How to get a Solana RPC endpoint for enterprise (2026 guide)

TL;DR

Your finance team should not be the first to know that a stablecoin settlement failed on Solana — but on a shared public endpoint, that is exactly what happens. A lagging RPC node issues a near-expired blockhash, the transaction silently drops, and the failure surfaces in reconciliation the next morning rather than in an alert at the moment of broadcast. This guide covers the infrastructure architecture, security controls, and compliance requirements that enterprise teams need to run Solana reliably in production — from dedicated RPC nodes and high-availability topology to Chainstack for Enterprise contracts with SOC 2 guarantees and custom SLAs.

Why enterprises are building on Solana in 2026

Solana is no longer the developer-first experimental chain it was three years ago. The infrastructure decisions that enterprise teams make on Solana today are the same decisions that payment processors, asset managers, and regulated financial institutions have already made — and deployed.

Solana’s stablecoin supply reached $14 billion by end of 2025, a 3x increase from $5 billion in 2024. USDC transfer volume on Solana surpassed Ethereum for the first time in December 2025. The enterprises driving that volume are not startups: PayPal (PYUSD), WorldPay (USDG), and Western Union (USDPT, launching 2026) all issue or plan to issue stablecoins on Solana. Visa settles billions in USDC payment volume on Solana. Aon settled the first stablecoin insurance premium using PYUSD on Solana through Paxos. SoFi, with 15 million members and $50 billion in assets, is building an enterprise fiat and stablecoin banking service on Solana.

On the asset side, Solana’s tokenized real-world asset market reached $2.5 billion — including $1.59 billion in tokenized U.S. Treasuries. At this scale, the RPC endpoint is not a developer convenience. It is the trust layer that determines whether a payment settles, whether a fund redemption executes on time, and whether your audit trail is complete enough to satisfy a regulator.

What is a Solana RPC endpoint for enterprise

A Solana RPC endpoint is the network interface through which your application reads chain state, simulates transactions, and broadcasts signed instructions to validators. Solana exposes its own JSON-RPC method set — getAccountInfo, sendTransaction, simulateTransaction, getSlot, getSignaturesForAddress — over both HTTP and persistent WebSocket connections. There is no EVM namespace, no ABI encoding, and no hexadecimal block numbers. Solana uses base58-encoded addresses, lamports as the native denomination, and slot numbers as the primary height reference.

For enterprise operations, the RPC endpoint is the single point of contact between your business logic and on-chain settlement. Everything that touches Solana — stablecoin transfers, token redemptions, program state reads, compliance event monitoring — flows through it:

• Payment submission (sendTransaction) with commitment-level confirmation — processed, confirmed, or finalized
• Account state reads (getAccountInfo, getMultipleAccounts) for balances, token accounts, and program state
• Transaction simulation (simulateTransaction) to validate instruction logic before committing value
• Historical audit lookups via getSignaturesForAddress and getTransaction for compliance and reconciliation
• Real-time settlement monitoring via WebSocket accountSubscribe and logsSubscribe
• Full ledger history reconstruction for regulatory reporting — archive nodes only

You can review the full list of supported JSON-RPC methods in the Solana developer documentation.

The endpoint quality determines whether a $500,000 stablecoin settlement lands in the first available block or expires unnoticed. On Solana’s 400ms slot time and 150-slot blockhash expiry window, the margin for infrastructure error is measured in seconds — not minutes.

Enterprise vs developer RPC requirements

The gap between what an individual developer needs from an RPC endpoint and what an enterprise operation requires is structural, not just a matter of scale.

Requirement	Developer	Enterprise
Uptime	Best effort	99.99% SLA with financial penalties
Support	Community / ticket	Dedicated account team, 1-hour response SLA
Security	API key in env file	SSO, RBAC, MFA, key management service integration
Compliance	Not required	SOC 2 Type II, MiCA operational resilience, DORA
Billing	Per-request, one card	Consolidated invoice, purchase order, net-30 terms
Node type	Shared, global	Dedicated, single-tenant, region-specific
Data retention	Full node (2–3 days)	Archive node — full ledger history
Failover	Manual retry	Automated multi-region with <100ms failover
Audit trail	Not required	Complete RPC access logs for compliance reporting
Contract	Click-through ToS	Custom MSA with data processing agreement

Every row in this table is a gap that a public or standard managed endpoint leaves open. Enterprise procurement teams — and increasingly regulators under MiCA and DORA — treat each one as a risk item.

How Solana RPC differs from EVM chains

Enterprise teams migrating from Ethereum-based infrastructure need to unlearn several foundational assumptions before deploying Solana in production.

Solana’s API has no overlap with EVM JSON-RPC. There is no eth_* namespace, no ABI-encoded call data, no eth_getLogs, and no “contract address” concept. Solana programs are deployed to accounts — a single program may manage dozens of separate state accounts, each queryable independently via getAccountInfo. Log access follows a two-step pattern: getSignaturesForAddress to find transactions referencing an account, then getTransaction to retrieve instruction data and program logs. EVM developers accustomed to range-based eth_getLogs queries for event indexing will need to restructure their data access patterns entirely.

Finality on Solana uses three explicit commitment levels: processed (optimistic, can be rolled back), confirmed (supermajority stake vote), and finalized (maximum lockout, irrevocable). Every enterprise operation must specify commitment deliberately. Using confirmed for user-facing payment status and finalized for settlement records is the standard enterprise pattern — but the ~32-slot lag between them (~12–15 seconds) must be reflected in your confirmation UX and reconciliation timing.

The most significant architectural difference for enterprise is Solana’s real-time streaming layer. EVM chains offer eth_subscribe via WebSocket. Solana enterprise workloads that need sub-50ms account updates, real-time settlement monitoring, or slot-level compliance alerting use Yellowstone gRPC — a Geyser plugin interface that reads typed protobuf-encoded data directly from validator memory. There is no EVM equivalent. For payment processors monitoring settlement confirmation at institutional volume, this is not optional infrastructure.

Solana RPC endpoint options

Public vs private Solana RPC endpoints

Public Solana endpoints fail enterprise workloads in a way that is hard to detect until after the damage: they lag. An RPC node more than 150 slots behind the cluster stops issuing valid blockhashes. Your application signs a transaction, submits it, receives no error — and the transaction never lands. The failure shows up in the next reconciliation run. For a stablecoin payment processor handling hundreds of transactions per minute, this is not a latency problem. It is an operational risk.

Official public endpoints:

• Mainnet: https://api.mainnet-beta.solana.com
• Testnet: https://api.testnet.solana.com
• Devnet: https://api.devnet.solana.com

⚠️ Public endpoints enforce 100 requests per 10 seconds per IP, 40 concurrent connections, and no uptime guarantee. The Solana documentation explicitly states these endpoints are “not intended for production applications.” Enterprise operations require dedicated infrastructure with SLA-backed availability.

Feature	Public endpoint	Enterprise private endpoint
Access	Free and open	Restricted, credentialed
Resources	Shared, multi-tenant	Dedicated, single-tenant
Best use case	Development & testing	Production, regulated workloads
Uptime guarantee	None	99.99% SLA
Slot lag under load	Unpredictable	Managed with alert thresholds
Transaction landing	Unguaranteed	Optimized with Warp transactions
Archive access	Not available	Full ledger history
Yellowstone gRPC	Not available	Available as add-on
Support	Community	Dedicated account team, 1-hour SLA

📖 For a provider-by-provider performance comparison, see Best Solana RPC providers for fast and reliable production in 2026.

Enterprise stablecoin operations, regulated asset platforms, and payment processors cannot absorb the slot lag risk of shared infrastructure. The public endpoint is a development tool — not a counterparty you can include in an operational resilience plan.

Full node vs archive Solana node

Solana full nodes prune the ledger aggressively — standard nodes retain only two to three days of transaction history. For regulated enterprise workloads, that window is too short for compliance reporting, audit responses, and historical reconciliation.

Full node access	Archive node access
Current account balances and token positions	Complete ledger history from genesis
Live settlement confirmation monitoring	Historical getTransaction lookup at any slot
Real-time program state reads	Full SPL token transfer history for compliance
Recent signature history via getSignaturesForAddress	Reconstruction of account activity across months or years
Transaction simulation and broadcasting	MiCA/DORA-grade audit trail for any past operation
Validator vote and epoch data	DEX, DeFi, and RWA data backfills for analytics

Chainstack supports Solana archive nodes with access to the complete ledger for compliance and analytics use cases. The full Solana ledger is substantial in size — factor dedicated storage costs into TCO alongside compute when budgeting for archive infrastructure.

For any enterprise operation subject to MiCA, DORA, or internal compliance requirements, archive access is infrastructure, not an option. Regulators can request transaction history going back years. A full node cannot answer those queries.

HTTPS vs WebSocket

At enterprise settlement volumes, repeated HTTPS connections accumulate overhead that compounds under load. For payment processors handling hundreds of confirmations per minute, persistent WebSocket connections eliminate per-request handshake cost and reduce confirmation latency on hot paths.

Feature	HTTPS	WebSocket
Model	Request/response	Persistent connection
Complexity	Simple operationally	Requires reconnect/heartbeat logic
Best for	Balance reads, tx broadcast, archive queries, batch reconciliation	Settlement confirmation UX, real-time compliance alerting, slot monitoring
Latency	Standard	Lower for high-frequency updates
Connection overhead	Per request	One-time handshake

For enterprise compliance monitoring and real-time settlement alerting at Solana’s throughput, Yellowstone gRPC is the third tier. It delivers sub-50ms typed protobuf streams directly from validator memory — account changes, transaction events, slot notifications — for workloads where WebSocket polling latency is a measurable operational gap.

High-availability Solana RPC architecture

A single managed endpoint, however reliable, does not meet enterprise HA requirements. Node upgrades, regional network events, and validator cluster instability can all interrupt service for seconds to minutes. For stablecoin payment processors and regulated asset platforms, that window is too long.

A production enterprise Solana RPC architecture uses three tiers:

Primary endpoint — a dedicated node in your primary operating region (EU-West for MiCA-regulated entities, US-East for US-domiciled operations). All transaction submission and settlement confirmation flows through here during normal operations. Slot lag monitored continuously; alert if >30 slots behind cluster tip.

Secondary endpoint — a dedicated or managed node in a secondary region with the same provider. Automated failover triggers if primary error rate exceeds 1% over a 30-second window or if slot lag exceeds 100 slots. Failover time target: under 100ms with client-side endpoint rotation.

Tertiary fallback — a separate RPC provider entirely. This protects against provider-level outages, not just regional ones. Activates only when both primary and secondary are degraded simultaneously. Transaction monitoring must account for the ~60-second blockhash validity window during failover transitions.

This topology — two endpoints at one provider, one at another — gives 99.99%+ effective uptime without the complexity of a full multi-provider active-active setup. Every enterprise Solana deployment should have the fallback endpoint configured and tested under load before it is needed in production.

Security and compliance for enterprise Solana

SOC 2 Type II

SOC 2 Type II certification means an independent auditor has verified that a provider’s security, availability, and confidentiality controls function as claimed over a sustained period — not just at a point in time. For enterprise procurement, this is the minimum credentialing requirement. It is also what MiCA’s operational resilience requirements point to when assessing third-party infrastructure providers: independently audited controls, not self-attested claims.

SSO, MFA, and RBAC

Enterprise teams do not operate from a single developer account. A payment processor running Solana infrastructure typically has separate roles with different access needs:

• Developers — read endpoint credentials, deploy test nodes, access devnet
• Operations — monitor node health, manage failover configuration, rotate keys
• Finance — view usage reports and invoices only
• Auditors — read-only access to usage logs and billing history, no node credentials

Chainstack for Enterprise supports SSO integration with enterprise identity providers, MFA enforcement, and granular RBAC across projects. Credentials are never shared across roles.

Key management

RPC endpoint credentials are secrets. In enterprise environments they belong in a secrets management system — not in environment files, not in CI/CD variables, and never in source code. Chainstack’s key management service integrates with Google Cloud Secret Manager, Kubernetes Secrets, and Hashicorp Vault, providing a structured path for credential rotation and access auditing without manual secret handling.

MiCA and DORA compliance requirements

July 1, 2026 is the full MiCA enforcement deadline across all EU member states. For crypto-asset service providers operating under MiCA, your RPC infrastructure is part of your operational resilience scope under DORA — meaning it must meet documented reliability standards, be covered by incident reporting procedures, and support audit trail requirements.

In practical terms, this means:

• Provider SLA — your RPC provider must have a documented uptime commitment you can reference in your DORA risk register
• Incident reporting — RPC outages that affect service availability must be reportable; this requires monitoring and alerting, not just reactive troubleshooting
• Audit trail — transaction history must be reconstructable for regulatory requests; full node retention (2–3 days) is insufficient under most compliance frameworks
• Third-party concentration risk — DORA requires assessing concentration risk in critical third-party providers; using a single RPC provider without a tested fallback is a documented risk item

How to get a private Solana RPC endpoint for enterprise with Chainstack

To deploy a private Solana RPC node on Chainstack:

1. Log in to the Chainstack console (or create an account)
2. Create a new project
3. Select Solana as your blockchain protocol
4. Choose network: Mainnet or Testnet
5. Deploy the node
6. Open Access/Credentials and copy your HTTPS and WebSocket endpoints
7. Run a connectivity and slot-lag check before wiring into production

For enterprise teams requiring custom SLAs, dedicated account management, SSO integration, consolidated billing, and a signed MSA, start at Chainstack for Enterprise before provisioning nodes — the infrastructure configuration will depend on the contract terms.

Once your node is running, connect with @solana/kit — the current Solana JavaScript SDK that replaces the maintenance-only @solana/web3.js v1:

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

// createSolanaRpc accepts your Chainstack HTTPS endpoint directly
const rpc = createSolanaRpc("YOUR_CHAINSTACK_ENDPOINT");

// getBalance returns lamports as a bigint — no wei conversion needed
const balance = await rpc
  .getBalance(address("23dQfKhhsZ9RA5AAn12KGk21MB784PmTB3gfKRwdBNHr"))
  .send();

console.log(balance.value); // bigint, e.g. 1000000000n = 1 SOL

📖 For the full integration guide, see the Chainstack Solana tooling documentation.

You can also connect to your Chainstack Solana node directly from Claude, Cursor, Codex, Gemini, or Windsurf using Chainstack MCP. Learn more about Chainstack MCP.

Chainstack pricing for enterprise Solana RPC

Chainstack billing runs on a request-unit model — 1 RU per API call on full nodes, 2 RU per call on archive nodes — giving enterprise finance teams a cost structure that is straightforward to forecast and budget. See the full Chainstack pricing page for plan details and overage rates.

Plan	Cost	Requests/Month	RPS	Overage (per 1M extra)
Developer	Free	3M	25	$20
Growth	$49	20M	250	$15
Pro	$199	80M	400	$12.50
Business	$499	200M	600	$10
Enterprise	$990+	400M+	Unlimited	$5

Enterprise infrastructure add-ons for Solana:

• Archive Node add-on — full ledger history for compliance and analytics, starting at $49/month
• Unlimited Node add-on — flat monthly rate from $149/month, no per-request billing, 25–500 RPS tiers; predictable cost for high-volume payment ops
• Yellowstone gRPC add-on — from $49/month (1 stream) to $449/month (25 streams)
• Dedicated Nodes — from $0.50/hour compute; single-tenant, region-selectable, required for DORA third-party concentration risk documentation

Enterprise TCO framework

1. Determine whether archive access and Yellowstone gRPC are required — for regulated stablecoin or RWA workloads, both typically are, and they materially affect the cost floor before you size the base plan
2. Establish your baseline request volume from current infrastructure or a scoping exercise; archive calls count at 2 RU, so separate archive vs full-node traffic in your estimates
3. Map your peak RPS requirement — stablecoin payment processors often see 10–20x baseline RPS during market events; size for the peak, not the average
4. For DORA compliance, budget the secondary and tertiary endpoints as fixed infrastructure cost, not optional scale-up capacity
5. On Solana, a single compliance monitoring job using Yellowstone gRPC streaming 24/7 can consume more RPS budget than your transaction submission path — scope streaming workloads separately

Production readiness checklist

• Primary + secondary Global Nodes in different regions, plus a tertiary fallback at a separate provider
• Automatic endpoint failover configured and load-tested under simulated degradation
• Request timeout policy set (5–10 seconds for Solana RPC)
• Retry logic with exponential backoff; no indefinite retries on expired blockhashes
• All credentials in a secrets management system (Google Cloud Secret Manager, Kubernetes Secrets, or Hashicorp Vault) — never in code or CI/CD environment variables
• SSO and RBAC configured; separate roles for developers, operations, finance, and auditors
• SOC 2 Type II certification confirmed with your primary RPC provider; documented in your vendor risk register
• Commitment level specified explicitly on every call — confirmed for user-facing status, finalized for settlement records and compliance logs
• Slot lag monitoring in place — alert at >30 slots behind cluster tip, failover trigger at >100 slots
• Blockhash refresh logic implemented — re-fetch immediately before signing; never cache across user interactions or batch delays
• Yellowstone gRPC reconnect logic with JSON-RPC fallback to detect and backfill missed slot range
• Transaction landing rate tracked; Warp transactions enabled for high-value settlement operations
• Archive node access verified for all compliance-relevant account addresses before go-live
• RPC provider included in DORA third-party ICT risk register with documented SLA and concentration risk assessment

Troubleshooting common enterprise Solana RPC issues

Issue	Likely Cause	How to Fix
Stablecoin settlement missing from morning reconciliation	Transaction signed against stale blockhash from lagging endpoint; expired silently with no error	Implement slot lag monitoring with automated failover; add blockhash freshness check immediately before sign-and-submit
BlockhashNotFound on high-value transactions	RPC node >150 slots behind cluster tip during market congestion	Switch primary to dedicated node with monitored slot lag SLA; add getSlot comparison against cluster tip to health checks
Compliance audit request fails — historical transaction not found	Transaction falls outside full node retention (>2–3 days old)	Enable archive node access; verify getSignaturesForAddress with searchTransactionHistory: true for complete history
429 Too Many Requests during peak settlement volume	Public or Growth-tier endpoint RPS limit hit during market event	Move to Business or Enterprise tier; use Unlimited Node for payment paths with unpredictable burst traffic
WebSocket subscription drops during compliance monitoring	Idle timeout or network event; missed events not detected	Implement 30-second heartbeat ping; on reconnect, poll getSlot to identify missed slot range and backfill via getTransaction
Transaction simulates successfully but fails on-chain	Simulation used a different (lagging) node than broadcast; stale state during simulation	Ensure simulation and broadcast share the same dedicated endpoint; set commitment: "confirmed" on simulation calls
Yellowstone gRPC stream falls behind during Solana congestion	Buffer overflow under spike traffic; events queued faster than consumed	Scale consumer thread count; add exponential backoff reconnect; implement missed-event detection via HTTP getSlot polling during gap

Conclusion

The enterprises deploying on Solana in 2026 — Visa, PayPal, WorldPay, Western Union — are not treating RPC infrastructure as a commodity. They are treating it as a regulated operational dependency, the same way they treat payment rails, custody systems, and settlement networks. The MiCA enforcement deadline this July makes that framing mandatory for any EU-regulated entity: your RPC provider is a critical third-party ICT provider under DORA, and the auditor will want to see the SLA.

The infrastructure pattern that works for enterprise Solana is not a single managed endpoint with retry logic. It is a three-tier topology — primary dedicated node, regional fallback, provider-level fallback — with Yellowstone gRPC for real-time compliance monitoring, archive access for full audit trails, and a provider contract that covers SOC 2, SSO, and custom uptime guarantees in writing. On Solana’s 400ms slot time and 150-block expiry window, anything less is infrastructure you are hoping will hold up, not infrastructure you have verified will hold up.

Start with a free Chainstack tier to validate connectivity and slot-lag behavior against your own workload. For production deployments with custom SLAs, consolidated billing, and enterprise security controls, Chainstack for Enterprise covers the full stack under one contract.

FAQ

What enterprise compliance certifications should my Solana RPC provider hold? At minimum, SOC 2 Type II — independently audited, not self-attested. This is the standard that MiCA’s operational resilience requirements and most enterprise procurement processes reference when evaluating critical third-party providers. For EU-regulated entities under DORA, you also need a documented SLA (uptime commitment, incident response time, escalation path) that you can include in your third-party ICT risk register. Chainstack holds SOC 2 Type II and offers custom SLAs under enterprise contracts.

Do we need a dedicated node or is a managed global node sufficient for enterprise? For development and staging, managed global nodes are sufficient. For production workloads handling real financial value — stablecoin payments, RWA redemptions, tokenized asset transfers — dedicated nodes are required. Dedicated means single-tenant: your traffic does not compete with other customers during market events. It also means a specific, documentable node identity for your DORA third-party register, rather than a shared infrastructure pool you cannot audit independently.

How does Solana’s blockhash expiry window create operational risk for enterprise payment systems? Solana blockhashes expire after approximately 150 slots — roughly 60–90 seconds at normal slot times. For enterprise payment systems that involve user confirmation flows, batch processing queues, or any delay between blockhash fetch and transaction broadcast, the expiry window is a live operational risk. A payment authorization collected from a user may arrive at broadcast with a blockhash that is 30–40 slots from expiry — and if the RPC node is lagging, it may already be expired. The production pattern is to re-fetch the blockhash immediately before signing and to monitor your node’s slot position continuously. The business risk is a payment that the customer believes they submitted but that never settled, discovered hours later.

What does Yellowstone gRPC do that standard WebSocket subscriptions cannot handle for enterprise? WebSocket subscriptions in Solana still route through the standard RPC stack — they are subject to the same slot lag as HTTP calls and do not provide the stream reliability that enterprise compliance monitoring requires. Yellowstone gRPC reads data directly from validator memory via the Geyser plugin, delivering typed protobuf-encoded updates with sub-50ms latency before data hits the RPC layer. For a regulated payment processor that needs to confirm settlement events in real time, or for a compliance system that must capture every token transfer event for MiCA reporting, the latency and reliability difference between WebSocket and gRPC is the difference between a system that works and one that requires manual event reconciliation.

How should we structure access controls for a multi-team Solana RPC deployment? Minimum RBAC pattern for enterprise: developers access devnet/testnet endpoints and read credentials for staging only; operations manage node configuration and failover but cannot access billing or audit logs; finance sees usage reports and invoices but has no node credentials; auditors have read-only access to usage logs and billing history with no operational permissions. All access managed through SSO integrated with your enterprise identity provider — no shared passwords, no personal accounts for production access. Chainstack for Enterprise supports SSO, MFA enforcement, and granular role assignment across projects.

What is the correct Solana commitment level for enterprise financial operations? Use confirmed for user-facing payment status and real-time confirmation UX — supermajority stake voting makes rollbacks extremely rare, and the reduced lag (~400ms) improves the settlement experience. Use finalized for all records with financial or regulatory weight: fund settlement entries, compliance logs, audit trail timestamps, and any data that will be exported to a reporting system or reviewed by an auditor. The ~32-slot lag between confirmed and finalized (~12–15 seconds) must be modeled explicitly in your settlement flow — do not record a payment as settled until finalized confirmation is received, even if the user-facing status updates at confirmed.
