What is Helius?
Helius is a Solana-only infrastructure provider that sells RPC nodes, LaserStream gRPC streaming, webhooks and token APIs. Its pricing page lists a free plan with 1M credits and 10 requests per second, and paid plans at $49, $499 and $999 per month.
How Helius works
Helius bills most work in credits.
A standard RPC call costs 1 credit, getProgramAccounts and every DAS asset call cost 10, and a parsed Enhanced Transaction costs 100. Your monthly allocation is spent first, then prepaid credits, which never expire, then autoscaling credits at $5 per million if you enable them. LaserStream nodes take shreds directly from Solana leaders and stream transactions, slots, blocks and accounts over gRPC that is wire-compatible with Yellowstone, with replay of up to 48 hours after a disconnect. Streaming data costs 2 credits per 0.1 MB.
Transactions can go out through Sender, which submits across the Helius, Jito, Harmonic and Rakurai pathways at once and consumes no credits. You pay a SOL tip instead, plus a priority fee. The pricing page lists a 0.000005 SOL minimum tip; the Sender docs say that minimum applies to the SWQOS-only tier (enabled with ?swqos_only=true, single path), while Sender Max needs at least 0.001 SOL and enters a priority tip buffer. Sender has 7 regional endpoints and a default limit of 50 transactions per second.
How to start with Helius
- Create a free account in the Helius dashboard without a card and copy the API key from the API Keys page.
- The free plan allows 10 RPC requests per second, 1 sendTransaction per second, 5 getProgramAccounts calls per second and 2 DAS requests per second.
- You can pay with a credit card or USDC on Solana, and annual billing gives 2 months free.
Helius fees and limits
- Paid plans are $49, $499 and $999 per month for 10M, 100M and 200M credits, with 50, 200 and 500 requests per second.
- Professional can add 100 RPS for $100 per month.
- LaserStream data add-ons, sold on Professional only, run from $400 per month for 5 TB to $6,000 for 100 TB, raw shred delivery costs $1,000 per month per IP ($800 on Professional), and dedicated nodes start at $2,900 per month.
Sender tips are a per-transaction cost on top of your plan and do not draw on Helius credits. The pricing page says autoscaling limits, real-time usage tracking and alerts can be set to control overage spend.
Risks to know before using Helius
- Tips between 0.000005 and 0.001 SOL are accepted by Sender but skip the priority buffer and use fewer pathways, so a contested trade may land later than expected.
- LaserStream on mainnet requires the $499 Business plan or higher.
- The billing docs say autoscaling is capped on Developer and Business but unlimited on Professional, with extra credits at $5 per million.
- Helius offers SOC 2 compliance on Enterprise plans.
