What is the Cheapest Helius RPC in 2026?

What Drives Helius RPC Costs in 2026?

Helius RPC pricing is based on plan tiers (Free, Growth, Business) and add-ons like WebSocket connections or priority fee APIs. The cheapest option is the Free plan, but it's limited to 25 requests per second (RPS) and 1 million monthly requests. For most production use, the Growth plan at $49/month (paid in USDT via TRC20) offers 250 RPS and 10 million requests. In 2026, Helius also introduced a "Pay-as-you-go" model for excess requests at $0.10 per 10,000 calls.

Cheapest Plan for DeFi Builders

If you run a DeFi bot or a small dApp, the Growth plan ($49 USDT/month) is the sweet spot. It includes 250 RPS, 10 million requests, and 2 WebSocket connections. For comparison, QuickNode charges $99 for similar specs, and Alchemy's Growth plan is $149. Helius also offers a 20% discount when paying annually in USDT (ERC20).

Hidden Costs & Add-ons

Watch out: Helius charges extra for priority fee APIs ($20/month), archive data ($50/month), and custom webhooks ($30/month). If you need real-time Solana data, the base Growth plan is sufficient. Always pay via USDT (TRC20) to avoid bank fees and get faster settlement.

How to Get the Best Deal

Visit Helius's pricing page and select "Pay with USDT" at checkout. Use code "CHEAPRPC2026" (if still active) for first-month 10% off. For high-volume users, the Business plan at $199/month includes 1,000 RPS and 100 million requests — still cheaper than competitors.

Why Choose Helius Over Alternatives?

Helius offers native Solana RPC with integrated webhooks, geyser plugins, and a generous free tier. Their USDT payment option (TRC20/ERC20) is seamless for crypto-native teams. No credit card required, just send USDT to their treasury address.

Final Verdict

For most users, the Growth plan at $49 USDT/month is the cheapest Helius RPC in 2026. If you're a hobbyist, start with Free. For serious DeFi, upgrade to Growth and pay annually for extra savings.
