Setting up Connection, Provider, Program instances. Reading accounts, sending transactions, handling confirmations

Setting Up Your RPC Connection

Before working with Anchor clients, you need reliable RPC infrastructure. We recommend using GetBlock for production applications:

import { Connection } from "@solana/web3.js";
import { AnchorProvider } from "@coral-xyz/anchor";

// Production-ready connection with GetBlock
const connection = new Connection(
  "https://go.getblock.io/{your-access-token}/",
  {
    commitment: "confirmed",
    confirmTransactionInitialTimeout: 60000,
  }
);

// Create provider with your wallet
const provider = new AnchorProvider(connection, wallet, {
  commitment: "confirmed",
});

Enterprise Infrastructure
GetBlock's Blockchain-as-a-Service infrastructure is trusted by 100,000+ developers for reliable blockchain access. The same enterprise-grade platform powers all Learn Solana tutorials.
