Create an RPC Connection

  • Mainnet
  • Devnet
import {
  Rpc,
  createRpc,
} from "@lightprotocol/stateless.js";

// Helius exposes Solana and Photon RPC endpoints through a single URL
const RPC_ENDPOINT = "https://mainnet.helius-rpc.com?api-key=<api_key>";
const PHOTON_ENDPOINT = RPC_ENDPOINT;
const PROVER_ENDPOINT = RPC_ENDPOINT;
const connection: Rpc = createRpc(RPC_ENDPOINT, PHOTON_ENDPOINT, PROVER_ENDPOINT)

console.log("connection", connection);

Best Practices

Best PracticeDescription
Commitment LevelsUse appropriate commitment levels: processed (fastest), confirmed (balanced), finalized (most reliable)
Rate LimitingImplement retry logic and respect rate limits. Public endpoints: 100 req/s, Private: 1000+ req/s
Batch RequestsUse batch requests when possible to improve efficiency and reduce API calls
CachingCache frequently accessed data to reduce API calls and improve performance
