What makes Helius RPCs Different?

At Helius, we are Solana natives. We've been here since the beginning — and unlike other providers, we are exclusively on the Solana blockchain — focused on perfecting the Solana experience.
We pride ourselves in having the most well-rounded RPC offering in the entire ecosystem. Top 1% in performance, top 1% in pricing, and the most consistent uptime, no surprises. If you run into any issues, we provide best-in-class 24/7 support to help unblock you and keep you moving forward.

How to use Helius RPCs?

Simply generate an API key at dev.helius.xyz and your RPC URLs will be created for you. We provide controls to fine-tune your RPC access patterns (only allow requests from certain IPs or domains). You can configure these in our dev portal.

RPC Documentation, Testing, and Benchmarks

We've created an open-source tool for you to test, benchmark, and learn the Solana RPC methods in an interactive way, with code samples. Think Postman but for Solana RPCs — you can find it here:
