Solana RPC for payment processors: best providers and infrastructure guide 2026

When Visa settled $3.5 billion in annualized USDC volume through Solana by December 2025 and PayPal expanded its PYUSD cross-border remittance pilot in March 2026, choosing the right Solana RPC provider moved from a developer concern to a business-critical decision. USDC transfer volume on Solana surpassed Ethereum’s in late December 2025, and Solana now processes roughly 35% of all on-chain stablecoin transfers globally by transaction count.

Quick verdict: best Solana RPC providers for payment processors in 2026

Chainstack is our top pick for regulated Solana payment processors that need isolation, predictable billing and audited attestation, based on Dedicated Nodes, method-agnostic request-unit pricing, the Unlimited Node add-on, SOC 2 Type II and ISO 27001, and a contractual Enterprise SLA. This is an editorial judgment, not a latency ranking: Chainstack publishes this page and is one of the six listed providers, and in the Chainstack Compare 24-hour snapshot below Quicknode ranks first on latency score and Chainstack second. See how we compared before relying on the order. The best fit by need:

• Best for regulated payment processors that need isolation, flat-rate options and a contractual SLA: Chainstack (Dedicated Nodes, Unlimited Node add-on, SOC 2 Type II + ISO 27001, Enterprise SLA).
• Best for multi-chain payment stacks and the broadest certification list: Quicknode (SOC 2 Type II, SOC 1, ISO 27001; staked submission through Transaction Fastlane and Lil’JIT; lowest latency score in the Compare snapshot).
• Best for Solana-only stacks that need webhooks and enriched token data: Helius (webhooks, DAS API, LaserStream; SOC 2 compliance listed on its pricing page, report type not verified).
• Best for technically sophisticated teams that want usage-based pricing and streaming depth: Triton One (Yellowstone authors, bare-metal nodes, $10/M standard calls; no published SOC 2; not measured by Compare).
• Best for development, testing and lower-volume production: Alchemy (30M CU free tier, SOC 2 Type II report listed on its Trust Center; no Solana dedicated nodes).
• Best as a low-cost secondary broadcast or backup path: dRPC (free public endpoints, $6/M requests; no published SOC 2 found; no SLA on free public endpoints, committed SLAs on Enterprise).

Solana RPC providers for payment processors compared (2026)

Rows follow the article’s own editorial order (Chainstack first, then the order of the provider sections below), not a benchmark ranking. Provider figures reflect public positioning as of May 2026, as stated in the original article. The Compare 24h rank column comes from the snapshot described in the benchmark section.

Rank (editorial)	Provider	Best for	Pricing model	Free tier	Dedicated nodes	gRPC streaming	SOC 2	Compare 24h rank (by score)
1	Chainstack	Regulated payment processors needing isolation and a contractual SLA	RU (1 RU/request, method-agnostic)	3M RU/month, 5 RPS on Solana Mainnet	Yes (from Pro plan)	Yes — Yellowstone ($49/mo add-on)	Type II	2nd of 5 measured
2	Quicknode	Multi-chain payment stacks, broadest certifications	Credits (30 credits/Solana call)	1M credits/month	Yes (enterprise pricing)	Yes — Streams add-on	Type II + SOC 1 + ISO 27001	1st of 5 measured
3	Helius	Solana-only stacks needing webhooks and token data	Credits (method-weighted)	1M credits/month, 10 RPS	Yes (~$2,900/month)	Yes — LaserStream (Business plan+)	Not published	3rd of 5 measured
4	Triton One	Technical teams wanting usage-based pricing and streaming depth	Usage-based ($10/M standard calls)	$125 min deposit	Yes (~$2,900/month)	Yes — Fumarole (included)	Not published	Not measured
5	Alchemy	Development, testing, lower-volume production	CU-based (~27 CU/request, Alchemy’s planning average)	30M CU/month	No	gRPC listed on pricing page (from $75/TB, pay-as-you-go); Yellowstone compatibility not verified	Type II	4th of 5 measured
6	dRPC	Low-cost backup broadcast path	Per-request ($6/M standard requests paid)	Public endpoints, no SLA; paid plans list 99.96% uptime, Enterprise committed SLAs	No	No	Not published	5th of 5 measured

The 2026 inflection point for payment processors is compliance and scale converging simultaneously. The GENIUS Act in the US and MiCA in Europe are now in effect, meaning regulated payment processors need audited vendor attestation — not just uptime charts — from their RPC infrastructure. At the same time, stablecoin supply on Solana tripled between end-2024 and early 2026 to over $15 billion, and the transaction volumes that follow demand infrastructure that holds up under load, not just during office-hours demos.

This guide compares six Solana RPC providers evaluated specifically through a payment-processor lens: settlement certainty, infrastructure isolation, compliance posture, and the RPC methods that drive real-time payment flows.

Payment processing on Solana: RPC requirements

Payment workloads on Solana are not like DeFi trading or NFT minting. The latency budget is not sub-50ms. The budget is the window between a customer clicking “pay” and seeing “confirmed”: 1–3 seconds for acceptable consumer UX. Miss it and you are either holding the payment pending (bad customer experience) or releasing goods before finality (financial risk). The RPC layer is where that budget is spent or burned.

Latency and finality requirements

Solana produces blocks every 400 milliseconds. Transactions reach confirmed status (2/3 validator consensus) in 1–2 seconds and finalized status in approximately 13 seconds. For most consumer payments, confirmed is sufficient and appropriate. For high-value settlement or regulated flows (wire-equivalent transfers, payroll disbursements, any transaction where rollback risk cannot be accepted), finalized is required.

Production latency is not network latency; it is end-to-end RPC latency under load. Shared public endpoints can deliver 500ms–2+ seconds of p95 latency during Solana congestion events (an approximate figure from the original article, not measured here). A payment processor handling thousands of concurrent settlement requests cannot tolerate that variance. The benchmark that matters is p95 latency under burst traffic from your target deployment region — not the average latency figure that most providers publish in their marketing copy.

Throughput requirements

Payment processors exhibit burst traffic patterns: settlement windows, payroll runs, and reconciliation batches all generate request spikes that can be 10x or more above baseline. A shared endpoint that handles your average load may fail exactly when you need it most. Dedicated infrastructure — isolated RPC nodes or flat-rate throughput tiers — is, in our assessment, the most dependable way to secure headroom during those peaks without renegotiating capacity in real time.

Key RPC methods for payment processors

The methods below form the core of any Solana payment integration. Understanding their behavior under load determines which provider tier you actually need.

Method	Purpose	Payment-processor concern
getLatestBlockhash	Obtain a valid blockhash for transaction construction	Blockhashes expire after ~150 slots (~60 seconds). Stale hashes cause “Blockhash not found” failures during high-latency broadcast
simulateTransaction	Dry-run a transaction without committing	Catch insufficient funds and program errors before paying fees on a doomed transaction
sendTransaction	Broadcast a signed transaction to the network	With skipPreflight: false, the provider runs simulation first; skip only when you have already simulated
getSignatureStatuses	Poll confirmation status for one or more signatures	The primary confirmation polling method; must tolerate high call frequency without rate-limit degradation
getTokenAccountsByOwner	Retrieve all USDC/USDT token accounts for a wallet	Called on every new merchant onboard; can return large payloads for wallets holding many token types
getAccountInfo	Fetch raw account data including mint address	Critical for USDC mint validation — any token can claim the name “USDC,” so always verify the mint address matches the canonical USDC mint before crediting a merchant
getBalance	SOL balance lookup for a public key	Verify the payer has enough SOL to cover transaction fees before attempting to send

WebSocket subscriptions — signatureSubscribe and accountSubscribe — are the preferred alternative to polling getSignatureStatuses at high frequency. A single WebSocket connection surfaces the confirmation event within ~100ms of validator consensus. At 10,000 concurrent payments, switching from 500ms polling intervals to WebSocket subscriptions eliminates millions of redundant RPC calls per hour and removes the thundering-herd effect of synchronized polling bursts.

⚠️ Finality levels matter: A processed status means the transaction was included in a block but can still be dropped if that block is not voted into the canonical chain. Wait for confirmed (1–2 seconds) before releasing digital goods or reporting success to the customer. For regulated payment flows or wire-equivalent settlement, wait for finalized (~13 seconds).

Infrastructure requirements: Payment processors should run on dedicated or isolated infrastructure. Shared endpoints introduce noisy-neighbor risk — another application’s batch job can saturate the connection pool exactly when your settlement window opens. Archive access is needed for payment audit trails: fetching a historical transaction requires archive-class storage. Geographic proximity to your RPC endpoint matters: if your payment servers run in Frankfurt and your RPC is routed through a US node, you add 100ms+ of avoidable round-trip to every transaction.

Chainstack for payment processors on Solana

Chainstack’s stablecoin infrastructure platform is purpose-positioned for this workload: SOC 2 Type II and ISO 27001 certified, built for cross-border settlement, and designed for the compliance documentation that regulated payment teams actually need to file. The enterprise infrastructure offering extends this with contractual SLA, dedicated account management, and compliance documentation that regulated payment teams actually need.

• Global Nodes provide geo-balanced routing across multiple regions, directing each request to the lowest-latency available node. For payment processors with distributed customer bases, this removes the operational overhead of maintaining regional endpoint pools manually.
• Dedicated Nodes provide full infrastructure isolation: no shared compute, no noisy neighbors, no per-request billing surprises at month end. Dedicated Nodes use Chainstack’s Bolt fast-sync technology, which cuts bootstrapping time significantly so new capacity comes online fast when you need to scale before a known high-volume period. All Solana mainnet RPC methods are available, including archive access for historical transaction queries.
• Unlimited Node add-on converts RPC pricing to a flat monthly fee with defined RPS tiers from 25 to 500 RPS, starting at $149/month. For settlement workloads where request volume is predictable, this eliminates overage risk and makes cost forecasting straightforward.
• Yellowstone gRPC Geyser plugin streams blocks, transactions, and account changes in real time via Protocol Buffers. For payment processors currently polling getSignatureStatuses on a loop, switching to Yellowstone can reduce confirmation notification latency from 500ms polling cycles to sub-100ms event delivery. Available from $49/month for 2 streams, $149/month for 7 streams and $449/month for 25 streams.
• SOC 2 Type II and ISO 27001 certification means Chainstack’s security controls were independently audited over an extended period — not merely attested point-in-time. Compliance teams at regulated payment processors can request the SOC 2 report directly; it is the documentation that vendor onboarding processes at banks and fintech companies actually require.

The Enterprise plan includes a contractual SLA with a 99.9% quarterly uptime commitment and service credits of 10% or 25% of the quarterly fee (contractual SLA terms, separate from the platform uptime shown on the status page; see how we compared) — the legal paper trail your procurement team needs before routing live settlement volume through any third-party infrastructure provider.

Code example: polling payment confirmation on Chainstack

The snippet below uses @solana/kit to fetch a fresh blockhash, simulate before sending, send the transaction, and poll confirmation status. See the Solana tooling documentation for full SDK setup and modern patterns.

import { createSolanaRpc, commitment } from "@solana/kit";

const rpc = createSolanaRpc(process.env.CHAINSTACK_SOLANA_ENDPOINT!);

// Step 1: Get a fresh blockhash — expires after ~60 seconds
const { value: { blockhash, lastValidBlockHeight } } =
  await rpc.getLatestBlockhash({ commitment: commitment("confirmed") }).send();

// Step 2: Simulate before sending — catch errors before paying fees
const simulation = await rpc
  .simulateTransaction(encodedTransaction, { commitment: commitment("confirmed") })
  .send();

if (simulation.value.err) {
  throw new Error(`Simulation failed: ${JSON.stringify(simulation.value.err)}`);
}

// Step 3: Send (preflight already done in simulation)
const signature = await rpc
  .sendTransaction(signedTransaction, { skipPreflight: true, preflightCommitment: commitment("confirmed") })
  .send();

// Step 4: Poll until confirmed
async function awaitConfirmation(sig: string): Promise<"confirmed" | "failed" | "pending"> {
  const { value } = await rpc
    .getSignatureStatuses([sig], { searchTransactionHistory: false })
    .send();
  const status = value[0];
  if (!status) return "pending";
  if (status.err) return "failed";
  if (status.confirmationStatus === "confirmed" || status.confirmationStatus === "finalized") {
    return "confirmed";
  }
  return "pending";
}

Provider-by-provider comparison for Solana payment processors

The sections below follow the editorial order of the table above. Each section ends with a verdict that names the main trade-off and links the provider’s official pricing page.

1. Chainstack: best for regulated payment processors that need isolation and a contractual SLA

Verdict: Dedicated Nodes, method-agnostic RU pricing, the Unlimited Node add-on, SOC 2 Type II and ISO 27001. Trade-off: Growth plan or above is needed for Yellowstone streaming, and the Compare snapshot below shows a weaker US P95 and P99 than Quicknode. Chainstack publishes this page. Official pricing: Chainstack pricing.

In our assessment, Chainstack’s method-agnostic RU pricing is the most predictable billing model in this comparison for payment workloads. A getSignatureStatuses confirmation poll costs the same as a getBalance call — 1 RU. Payment processors running high-frequency confirmation loops can model their monthly cost accurately without tracking per-method credit multipliers.

Dedicated Nodes provide the infrastructure isolation that high-value settlement flows require. No shared compute, no noisy neighbors, and Bolt fast-sync for rapid capacity expansion. The Unlimited Node add-on sits above that for teams that want flat-rate unlimited requests within a defined RPS ceiling — the correct model when your confirmation polling volume is predictable but high. The Yellowstone gRPC Geyser plugin is available from $49/month as a marketplace add-on, making real-time settlement streaming accessible at a lower entry cost than Helius’s LaserStream or a dedicated Triton One contract.

SOC 2 Type II and ISO 27001 certification and the contractual enterprise SLA make Chainstack, in our assessment, a strong infrastructure choice for regulated payment processors going through vendor due diligence; Quicknode additionally lists SOC 1 (see below). The full pricing range spans Developer (free, 3M RU, 5 RPS on Solana Mainnet) through Enterprise ($990+/month, 400M+ RU).

Limitations: The Yellowstone gRPC Geyser plugin streaming add-on requires Growth plan ($49/month) or above — the free Developer tier does not include streaming. In the Chainstack Compare 24-hour snapshot below, Chainstack ranks second of the five measured providers on Solana: it has the lowest P50 but a weaker US P95 and P99 than Quicknode. Chainstack operates Compare, so read that data with the disclosure in the benchmark section.

Fit for payment processors: Strong in our assessment — method-agnostic pricing, SOC 2 Type II and ISO 27001, Dedicated Nodes for isolation, contractual SLA for regulatory compliance, and a low-cost entry point for gRPC streaming ($49/month add-on; Triton One’s Fumarole is included in its plans).

2. Quicknode: best for multi-chain payment stacks and the broadest certification list

Verdict: SOC 2 Type II, SOC 1 and ISO 27001, staked submission paths and multi-chain coverage. Trade-off: method-weighted credits, and dedicated infrastructure is enterprise-tier only with custom pricing. Official pricing: Quicknode pricing.

In our assessment, Quicknode is the strongest option for payment processors already operating across Solana and multiple EVM chains simultaneously. A single vendor relationship, unified billing, and shared compliance documentation across Ethereum, Polygon, Solana, and 60+ other chains simplify vendor management for treasury and legal teams. For payments infrastructure that spans stablecoin settlement on Solana and EVM-based fiat on-ramp flows, consolidating on Quicknode reduces the number of vendor security reviews your procurement team must complete.

For Solana specifically, Quicknode provides Transaction Fastlane and Lil’JIT — first-party staked submission paths that improve transaction landing rates during network congestion. For payment processors where a dropped sendTransaction means a failed payment, this infrastructure advantage is meaningful: stake-weighted Quality of Service routes your transactions through validators with preferential processing relationships. Quicknode’s credit-based pricing charges 30 credits per standard Solana RPC call, with paid plans starting at $49/month and overage rates ranging from $0.62/1M credits downward on higher tiers.

Quicknode lists the broadest set of certifications of the six providers in this comparison: SOC 1 Type 2, SOC 2 Type 2 and ISO/IEC 27001 (reports available on request through its account team). For regulated payment processors going through vendor due diligence, Quicknode’s certification list is the longest in this comparison.

Limitations: The credit system’s method-weighted cost model requires tracking per-method usage to budget accurately. Dedicated infrastructure is enterprise-tier only with custom pricing — there is no self-serve dedicated node for Solana on standard plans. Archive and enhanced methods consume additional credits above the base 30-credit Solana call rate.

Fit for payment processors: Strong — the broadest certification list in this comparison, staked transaction submission, and multi-chain coverage. Optimal for teams standardized on Quicknode across multiple chains or those requiring ISO 27001 attestation.

3. Helius: best for Solana-only stacks that need webhooks and enriched token data

Verdict: Webhooks, DAS API and LaserStream on a Solana-only stack. Trade-off: Solana-only, SOC 2 report type not verified (its pricing page lists SOC 2 compliance), and a 10 RPS free tier that is thin for load testing. Official pricing: Helius pricing.

Helius is purpose-built for Solana and has, in our assessment, the strongest payment-specific tooling of the Solana-only providers in this comparison: webhooks for transaction event delivery, the Digital Asset Standard (DAS) API for token account metadata, and LaserStream for low-latency gRPC streaming. For payment processors that need to watch merchant wallets for incoming USDC payments and trigger fulfillment workflows automatically, Helius webhooks are, in our assessment, the most developer-friendly event delivery mechanism in this comparison — no polling loop required.

LaserStream gRPC streaming delivers Solana slot data via Protocol Buffers at low latency. Available on mainnet from the Business plan ($499/month, 200 RPS), with the Professional plan ($999/month, 500 RPS) adding direct Slack/Telegram support for latency-critical production workloads. Dedicated nodes are available from approximately $2,900/month with hybrid options combining dedicated backend compute with load-balanced frontend endpoints.

For Solana-only payment processors building consumer-facing flows — wallet lookup, token account management, real-time payment confirmation — Helius’s enriched API layer provides value above raw RPC. Helius’s pricing page lists SOC 2 compliance (Enterprise plan) without stating the report type or date, so regulated entities should request the report before relying on it.

Limitations: Helius is Solana-only. Payment processors operating across multiple chains need a separate RPC vendor. SOC 2 compliance is listed on its pricing page, but the report type and date are not stated (not verified here), so regulated teams should request the report. The free tier (10 RPS) is insufficient for production load testing.

Fit for payment processors: Strong for Solana-only stacks needing webhook delivery and enriched token data. The compliance gap limits applicability for regulated payment processors or enterprise fintech teams.

4. Triton One: best for technical teams that want usage-based pricing and streaming depth

Verdict: Yellowstone authors, bare-metal nodes and transparent usage-based pricing. Trade-off: no published SOC 2, engineering-led support, and not measured by Compare so no like-for-like latency data is available. Official pricing: Triton One pricing.

Triton One’s engineering lineage is directly relevant to Solana payment infrastructure: the team built Project Yellowstone, the Geyser plugin that is widely used for real-time streaming across the Solana ecosystem. Publicly reported p50 figures of around 100ms (early 2026 benchmarks, not verified for this article) are cited for Triton One; Compare does not measure Triton One, so this article has no like-for-like latency comparison for it. The bare-metal node architecture avoids the hypervisor overhead that can affect cloud-hosted providers during burst traffic.

Triton’s usage-based pricing is transparent: $10/M calls for standard RPC, $25/M for historical ledger access. No rigid tier walls, no credit multipliers. You pay for actual usage. The $125 minimum deposit functions as a commitment threshold rather than a plan tier, making it accessible for early-stage payment integrators who want premium Solana infrastructure without committing to a $499/month plan. Fumarole, Triton’s persistent streaming service, was made free on all plans through June 2026 (that period has ended as of this update, so confirm current terms before relying on it) — a low-risk way to evaluate gRPC-based settlement notifications before committing to streaming infrastructure budget.

Dedicated nodes start at approximately $2,900/month and are built on the same bare-metal infrastructure that handles institutional trading and MEV workloads — the same durability profile that high-value payment settlement requires.

Limitations: No published SOC 2 certification. Support is engineering-led rather than enterprise account management, which creates friction during vendor due diligence processes at regulated institutions. The usage-based pricing model requires active monitoring to avoid unexpected bills during volume spikes.

Fit for payment processors: Strong for technically sophisticated teams prioritizing raw performance, streaming depth, and transparent pricing. Limited for regulated entities requiring compliance documentation during vendor onboarding.

5. Alchemy: best for development, testing and lower-volume production

Verdict: A 30M CU free tier, SOC 2 Type II and strong dashboard tooling. Trade-off: no Solana dedicated nodes, so all Solana traffic runs on shared infrastructure, and Yellowstone compatibility of its Solana gRPC offering is not verified here. Official pricing: Alchemy pricing.

Alchemy supports Solana via standard JSON-RPC over HTTP and WebSocket. The free tier provides 30M CUs per month — approximately 1.1M requests at Alchemy’s stated planning average of 27 CU per request — making it accessible for building and testing a full payment integration without upfront cost. In our assessment, Alchemy’s dashboard analytics and debugging tooling are among the stronger options for rapid iteration during integration development.

For production Solana payment processing, Alchemy’s principal constraint is infrastructure isolation: dedicated node options are not available for Solana as of May 2026, meaning all Solana traffic runs on shared infrastructure. During Solana congestion events, shared endpoint users can be disproportionately affected by latency degradation. Alchemy’s pricing page lists Solana gRPC streaming (from $75/TB on pay-as-you-go); whether it is Yellowstone-compatible is not verified here, so confirm it before relying on it for settlement event delivery. Alchemy’s Trust Center lists a SOC 2 Type II report (held by Alchemy Insights, Inc., available on request) and no ISO 27001 as of October 29, 2026, which supports vendor onboarding for teams that need SOC 2 only.

Limitations: No dedicated nodes for Solana. Yellowstone compatibility of its Solana gRPC offering is not verified. CU pricing requires tracking method-specific credit consumption to forecast costs. Shared-only infrastructure limits applicability for high-value settlement flows that require p95 latency guarantees.

Fit for payment processors: Moderate — well-suited for Solana payment integration development and testing, lower-volume production, or as an additional endpoint in a multi-provider failover setup. The shared infrastructure is a constraint for high-value settlement flows.

6. dRPC: best as a low-cost secondary broadcast path

Verdict: $6/M pricing, free public endpoints and a decentralized node pool. Trade-off: no dedicated nodes, no published SOC 2 found, no SLA on free public endpoints (committed SLAs are Enterprise only), and the highest latency of the five providers Compare measures. Official pricing: dRPC pricing.

dRPC routes Solana traffic across a network of 50+ independent node operators using an AI-driven load balancer, with support for stake-weighted Quality of Service. The decentralized architecture can provide geographic redundancy across operators, and the pricing is at the low end of the comparison at $6/M standard requests on paid plans with free public endpoints for development.

For payment processors, dRPC’s most relevant role is as a secondary broadcast path or backup confirmation endpoint in a multi-provider setup. Sending the same signed transaction through both a primary provider (Chainstack or Helius) and dRPC simultaneously can increase the probability of a transaction landing during network congestion at little added cost. As a primary settlement endpoint, the absence of dedicated infrastructure, no published SOC 2 found, and no SLA on free public endpoints (committed SLAs are Enterprise only) present meaningful operational risk for high-value payment flows.

Limitations: No dedicated nodes. No published SOC 2 found. No SLA on free public endpoints; paid plans list 99.96% uptime and Enterprise lists committed SLAs. Public endpoints carry no performance guarantees. Best suited as a backup broadcast path rather than a primary settlement endpoint for a production payment processor. In the Compare snapshot below, dRPC shows the highest latency of the five measured providers (P95 672 ms, against 39–73 ms for the others).

Fit for payment processors: Limited as a primary provider. Genuinely useful as a low-cost redundancy layer or development endpoint.

Payment-processor criteria by provider

An earlier version of this page showed a numeric 100-point chart that gave Chainstack 97/100; the chart gave no published rubric for how each provider was rated, so it has been replaced by this table. Each cell restates a fact from the provider sections above. “Not stated” means the article gives no figure.

Provider	Dedicated or isolated infrastructure	Contractual SLA or uptime evidence	Compliance certification	Payment-specific tooling (gRPC, webhooks, submission)	Latency (Compare 24h snapshot, P95 / P99)
Chainstack	Dedicated Nodes with full isolation (from Pro plan); Unlimited Node add-on	Enterprise plan: contractual SLA with a 99.9% quarterly uptime commitment	SOC 2 Type II and ISO 27001	Yellowstone gRPC ($49/mo add-on); webhooks not stated	44 ms / 85 ms (2nd of 5 measured)
Quicknode	Enterprise-tier only, custom pricing	Not stated	SOC 2 Type II, SOC 1, ISO 27001	Streams add-on; Transaction Fastlane and Lil’JIT staked submission	39 ms / 52 ms (1st of 5 measured)
Helius	Dedicated nodes from about $2,900/month; hybrid options	Not stated	SOC 2 compliance listed on pricing page; report type not verified	LaserStream (Business plan+), webhooks, DAS API	65 ms / 154 ms (3rd of 5 measured)
Triton One	Dedicated nodes from about $2,900/month, bare-metal	Not stated	No published SOC 2	Fumarole (included), Yellowstone authors	Not measured
Alchemy	No Solana dedicated nodes (as of May 2026); shared infrastructure	Not stated	SOC 2 Type II report listed on its Trust Center; no ISO 27001 listed (as of October 29, 2026)	Solana gRPC listed on pricing page (from $75/TB); Yellowstone compatibility not verified	73 ms / 91 ms (4th of 5 measured)
dRPC	No dedicated nodes	No SLA on free public endpoints; Enterprise committed SLAs	No published SOC 2 found	Stake-weighted QoS support; no gRPC	672 ms / 1.10 s (5th of 5 measured)

Solana RPC latency benchmark: Chainstack Compare 24-hour snapshot

Disclosure: Chainstack operates Chainstack Compare and chose the ranking formula, and Chainstack is one of the providers measured. The table below is a rolling 24-hour view captured on October 29, 2026 at about 12:54 UTC. The live dashboard refreshes every 3 minutes, so current figures will differ. It is a snapshot, not a dated research report. The Compare dashboard headline for this view reads “Quicknode ranks #1 for Solana”.

Method in brief: probes from three regions (Germany, US, Singapore) every 1–3 minutes, each provider on its entry paid plan. Score = response time / success rate cubed per region, lower is better, with the three regions averaged equally. Compare labels the success-rate column “availability”; it is the share of probe requests that succeeded, not platform uptime. P50, P95 and P99 are response-time percentiles; the regional columns are P95 per region.

Provider (editorial order)	Score (lower is better)	Probe success rate	P50	P95	P99	DE P95	US P95	SG P95
Chainstack	0.045	99.97%	21 ms	44 ms	85 ms	28 ms	64 ms	40 ms
Quicknode	0.039	99.99%	29 ms	39 ms	52 ms	28 ms	44 ms	46 ms
Helius	0.067	99.99%	38 ms	65 ms	154 ms	43 ms	100 ms	51 ms
Triton One	Not measured	–	–	–	–	–	–	–
Alchemy	0.078	100.00%	40 ms	73 ms	91 ms	25 ms	43 ms	150 ms
dRPC	0.782	100.00%	148 ms	672 ms	1.10 s	632 ms	938 ms	447 ms

What the snapshot shows: Quicknode ranks first on score (0.039) with the lowest P95 and P99, and Chainstack ranks second (0.045). Chainstack has the lowest P50 (21 ms) and the best Singapore P95 (40 ms), but a higher US P95 (64 ms, against 44 ms for Quicknode and 43 ms for Alchemy) and a higher P99 (85 ms) than Quicknode (52 ms); the P99 of Alchemy is 91 ms. Helius scores 0.067 and Alchemy 0.078. Alchemy has the best DE P95 (25 ms) and US P95 but the weakest Singapore P95 of the top four (150 ms). dRPC scores 0.782, with a P95 of 672 ms and a P99 of 1.10 s. For payment flows, where the tail decides the customer experience, P95 and P99 matter more than P50.

What this benchmark does not show: Triton One is not measured, so no latency comparison is made for it. The snapshot covers one 24-hour window on entry paid plans using synthetic probes from three cloud regions; it does not measure sendTransaction landing rate, confirmation time, throughput under load, dedicated nodes, gRPC streaming, cost or correctness, and it is not end-user latency. Test from the region where your payment servers run.

To reproduce a basic read-path measurement against any endpoint, run the request below repeatedly and compare the median and the 95th percentile. See how to measure RPC latency (P50, P95, P99) for the full method.

curl -s -o /dev/null -w "%{time_total} s" -X POST https://YOUR_ENDPOINT -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"getLatestBlockhash","params":[{"commitment":"confirmed"}],"id":1}'

For payment processors, the methods most worth benchmarking are getLatestBlockhash (called on every transaction construction), sendTransaction (broadcast latency), and getSignatureStatuses (your confirmation polling loop). The older Chainstack performance dashboard also tracks Solana with live latency across providers and regions.

Payment teams evaluating providers should run benchmarks from their production deployment region during business-hours traffic — not from a developer laptop at 2 AM. The p95 latency under realistic burst load is the number that actually determines whether a customer’s payment shows “confirmed” in 2 seconds or 8 seconds.

⚡ Benchmark before you commit: p95 latency is the metric that matters for payment UX — average latency hides the tail latency that your worst-case customers experience every time there is a congestion event. Check Chainstack Compare for a current view, and run your own test from your deployment region before committing to a provider contract.

For teams processing high settlement volumes, add the Unlimited Node add-on from the marketplace to convert to flat-rate billing, and add the Yellowstone gRPC Geyser plugin to replace confirmation polling with real-time streaming events.

The Solana tooling documentation covers full SDK setup with @solana/kit, Anchor v1.0.0 integration, LiteSVM for testing, and Backpack wallet configuration against your Chainstack endpoint.

🤖 You can also access Chainstack Solana RPC directly from Claude, Cursor, Codex, Gemini, or Windsurf using Chainstack MCP. Learn more about Chainstack MCP.

What a Solana API adds above the RPC layer

getProgramAccounts returns account bytes for an AMM program. A positions view needs them decoded into pool shares with USD values, and decoders break when a protocol ships a new version. CoinStats Solana API handles that decode layer: pre-priced SPL and SOL balances, staking, lending and LP positions resolved across 10,000+ protocols, and an MCP server for agents. CoinStats API runs no nodes and submits no transactions.

How we compared Solana RPC providers for payment processors

Disclosure: this comparison is published by Chainstack. Chainstack is one of the six providers listed and is placed first, so read the order as a vendor perspective and check figures against the official pricing pages linked in each provider section.

Criteria. Each provider is compared on the same attributes: pricing model, free tier, dedicated or isolated infrastructure, gRPC streaming and payment tooling, compliance certifications and SLA, and the RPC methods that drive payment flows. The order is an editorial judgment for regulated payment processors. It is not a benchmark result: the Compare snapshot above ranks Quicknode first and Chainstack second of the providers it measures, and it measures five of the six listed providers (Triton One is not measured).

Sources. Prices, limits and certifications are those stated in the provider sections above, taken from each provider’s public pages as of May 2026 unless a section says otherwise; plans change often, so confirm current figures on the linked official pricing pages. Where a provider does not publish a Solana-specific figure, the section says so instead of estimating one.

Platform uptime (Chainstack only). Chainstack shows 99.99%+ platform uptime (status.chainstack.com, Solana Mainnet, 99.99%+ over the 90 days to October 29, 2026). Status-page figures are for the Mainnet component of each chain; testnet and devnet components are tracked separately. This is platform uptime shown on the status page, separate from the benchmark’s probe success rate, not a guarantee, and not the contractual Enterprise SLA described above. The status page covers Chainstack only, so this article makes no uptime comparison with other providers.

Not covered. Other providers may also support Solana payment workloads. They are not part of this comparison.

Not legal or compliance advice. Statements about the GENIUS Act, MiCA and vendor attestation are those of the original article; confirm obligations with your own counsel.

Solana RPC rate limits and free tiers compared

Billing units differ between providers, so the same number of calls can cost different amounts. This table summarizes the figures stated in this article, as of May 2026; “Not stated” means the article gives no figure.

Provider	Free tier	Published RPS	Billing unit	Notes
Chainstack	3M RU/month, 5 RPS on Solana Mainnet	Developer 5 RPS and Growth 50 RPS on Solana Mainnet (Chainstack docs); Unlimited Node add-on 25–500 RPS	Request units (1 RU/request, method-agnostic)	Unlimited Node from $149/month; Yellowstone $49/month (2 streams), $149/month (7 streams) or $449/month (25 streams); Enterprise $990+/month, 400M+ RU
Quicknode	1M credits/month	Not stated	Credits (30 credits per Solana call)	Paid plans from $49/month; overage from $0.62/1M credits downward on higher tiers
Helius	1M credits/month, 10 RPS	Business 200 RPS; Professional 500 RPS	Credits (method-weighted)	Business $499/month; Professional $999/month; dedicated nodes from about $2,900/month
Triton One	$125 minimum deposit (no free tier stated)	Not stated	Usage-based ($10/M standard calls; $25/M historical ledger)	Dedicated nodes from about $2,900/month
Alchemy	30M CU/month (about 1.1M requests at 27 CU each)	Not stated	Compute units (~27 CU/request, Alchemy’s planning average)	No Solana dedicated nodes as of May 2026
dRPC	Free public endpoints, no performance guarantees	Not stated	Per-request ($6/M standard requests on paid plans)	No published SOC 2 found; no SLA on free public endpoints

Chainstack alternatives for Solana payment RPC

If Chainstack is not the right fit, these are the head-to-head differences between Chainstack and each alternative, using only figures from this article:

• Chainstack vs Quicknode: Quicknode lists SOC 2 Type II, SOC 1 and ISO 27001, offers staked submission through Transaction Fastlane and Lil’JIT and covers 60+ chains, and has the lowest latency score in the Compare snapshot; its credits are method-weighted and dedicated infrastructure is enterprise-tier only. Chainstack offers method-agnostic RU pricing, self-serve Dedicated Nodes from the Pro plan and the Unlimited Node add-on, and the lowest P50 in the snapshot.
• Chainstack vs Helius: Helius is Solana-only with webhooks, the DAS API and LaserStream (Business plan, $499/month, and above), but its SOC 2 report type is not verified here (its pricing page lists SOC 2 compliance); Chainstack holds SOC 2 Type II and ISO 27001 and offers Yellowstone gRPC from $49/month. In the Compare snapshot, Helius has a P95 of 65 ms against 44 ms for Chainstack.
• Chainstack vs Triton One: Triton One authored Yellowstone, offers bare-metal dedicated nodes from about $2,900/month and usage-based pricing ($10/M standard calls) with no published SOC 2; Chainstack starts at a free tier and holds SOC 2 Type II. Triton One is not measured by Compare.
• Chainstack vs Alchemy: Alchemy has a 30M CU free tier and a SOC 2 Type II report listed on its Trust Center (no ISO 27001 listed) but no Solana dedicated nodes, and Yellowstone compatibility of its Solana gRPC offering is not verified here; Chainstack offers Dedicated Nodes and Yellowstone as an add-on. In the Compare snapshot, Alchemy has a P95 of 73 ms against 44 ms for Chainstack.
• Chainstack vs dRPC: dRPC offers free public endpoints and $6/M standard-request pricing across 50+ independent operators but no dedicated nodes, no published SOC 2 found and no SLA on free public endpoints, and has the highest latency in the Compare snapshot (P95 672 ms); Chainstack offers isolation, SOC 2 Type II and a contractual Enterprise SLA.

Conclusion

The defining infrastructure decision for Solana payment processors in 2026 is whether your RPC layer can provide the isolation and compliance documentation that high-value settlement flows demand — not just whether it can handle average load.

The picks below follow the editorial order of the sections above. On latency, the Chainstack Compare 24-hour snapshot (see the benchmark section) ranks Quicknode first and Chainstack second of the five listed providers it measures; Triton One is not measured.

• Regulated payment processors and fintech companies requiring SOC 2 attestation and contractual SLA: Chainstack (SOC 2 Type II and ISO 27001, Dedicated Nodes, stablecoin infrastructure page) or Quicknode (SOC 2 Type II + SOC 1 + ISO 27001 for multi-chain stacks)
• Solana-only payment processors needing webhook event delivery and enriched token data: Helius (LaserStream, DAS API, webhooks)
• Latency-critical settlement infrastructure where raw performance and transparent pricing matter most: Triton One (bare-metal, Fumarole streaming, reported ~100ms p50 that Compare does not measure)
• Development, integration testing, or multi-provider failover broadcast: Alchemy (30M CU free tier) or dRPC (free public endpoints, decentralized node pool)
