Helius RPC provider overview (2026)

Solana teams care about two things: how quickly you can read state and how reliably you can land transactions when the network is busy. Helius leans into both with Solana‑specific plumbing, staked connections for sends, gRPC‑class streaming, and pre‑parsed data so you write less glue code.

Helius is a Solana-focused RPC provider and data platform that bundles staked RPC sends, Sender’s parallel submit path to Jito, Yellowstone-compatible LaserStream with replay and regional failover, faster Enhanced WebSockets, and DAS APIs for assets and transactions, all wrapped in a credit-based model with clear RPS caps and optional fixed-rate streaming tiers.

Where Helius fits (and where it doesn’t)

Best fit

• Solana‑only projects that need fast inclusion and low‑latency streams. Sender + staked defaults help when slots are tight.
• Teams that don’t want to maintain Yellowstone clusters; LaserStream is turnkey and adds replay/failover.
• Apps that hate writing parsers. DAS and Enhanced Transactions cover common asset and tx workflows.

Not ideal

• Multi‑chain roadmaps (you’ll need a second provider elsewhere).
• Workloads that can’t tolerate plan gating (e.g., LaserStream mainnet is Professional+; Enhanced WS sits on Business+).

Product surface

RPC nodes (HTTP/WSS). Paid plans use staked connections by default via the regular mainnet endpoint; “secure” masked URLs exist for frontends.

Streaming choices.

• LaserStream (gRPC) — drop‑in for Yellowstone; adds historical replay, auto‑reconnect, and multi‑region endpoints.
• Enhanced WebSockets — 1.5–2× faster on average than standard WS; now powered by the LaserStream backend.
• Webhooks — server‑to‑server pushes when you prefer HTTP over sockets.

Data APIs.

• DAS (Digital Asset Standard): ownership/metadata for tokens, NFTs, and compressed NFTs.
• Enhanced Transactions: human‑readable tx data + address history.
• getTransactionsForAddress: Helius‑exclusive, paginated, filterable history in a single method.

Send path.

• Sender: submits in parallel to Jito and Helius across 7 regions; no credits billed, min 0.001 SOL tip; tuned parameters recommended for speed.

Specialized option.

• Shred Delivery (beta): UDP feed of raw shreds for desks chasing single‑digit‑ms advantage.

Pricing at a glance

Helius uses a credit-based pricing model with additional pricing components for streaming and dedicated infrastructure.

Pricing is structured around three main components:

• Plans include monthly credits with request-per-second (RPS) caps.
• Data add-ons for LaserStream and Enhanced WebSockets are priced as fixed tiers ranging from 5 TB to 100 TB per month.
• Dedicated Solana nodes are listed as starting at around $2,900 per month.

Because RPC methods, streaming volume, and data services all consume credits or data bandwidth differently, total cost depends not only on request volume but also on streaming usage and the specific APIs used.

In this example, both workloads fit within included usage, but the pricing models differ significantly — request-based pricing ties cost directly to request volume, while credit-based pricing depends on method mix and streaming usage.

Tip: If streaming volume is your biggest cost variable, use right‑size filters and consider fixed‑rate tiers if you’re always on.

Strengths and trade‑offs

Helius vs. Chainstack

• Scope
  • Helius: Solana‑only, optimized around low‑latency streaming and fast inclusion.
  • Chainstack: Multi‑chain with managed Yellowstone gRPC and an Unlimited Node option for flat‑fee, RPS‑tiered scaling when you want predictable cost.
• Pricing posture
  • Helius: Credit plans + data add‑on for streaming; good when you want granularity and can size your data budget.
  • Chainstack: Transparent request‑based plans and flat‑fee Unlimited Node to cap spend under steady or bursty workloads.
