Migrating from Helius

Standard Solana JSON-RPC calls use the same method and response model; replace the endpoint and authentication.

Compatibility boundary

  • Standard Solana JSON-RPC methods retain their request and response shapes.
  • Standard Solana WebSocket subscription methods remain compatible.
  • Helius proprietary methods such as getAsset are not part of the Solana RPC standard and are not drop-in compatible.

  1. Update environment variables

    Before:

    HELIUS_API_KEY=your_keyHELIUS_RPC_URL=https://mainnet.helius-rpc.com/?api-key=your_key

    After:

    OPENINFRA_API_KEY=sk_live_xxxxxxxxxxxxOPENINFRA_RPC_URL=https://rpc.sol.openinfra.sh

  2. Attach the API key

    -const conn = new Connection(process.env.HELIUS_RPC_URL!);+const conn = new Connection(process.env.OPENINFRA_RPC_URL!, {+  commitment: "confirmed",+  httpHeaders: { "x-api-key": process.env.OPENINFRA_API_KEY! },+});

    For clients without custom header support, append ?api-key=YOUR_API_KEY.

  3. Replace provider-specific streams

    Evaluate Yellowstone gRPC or OpenInfra data streams based on the payload and filter behavior your application needs.
