Base Network IDs

ℹ️

The network ID is used to distinguish different Ethereum-compatible networks from each other. The Base mainnet always has network ID 8453.

Base NetworkNetwork IDChain ID
Base Mainnet84538453
Base Goerli (testnet)8453184531
Base Sepolia (testnet)8453284532

Use Cases

  1. Network Verification Confirm that you're connected to the correct Base network before sending transactions.

    // Check if connected to Base mainnet
const netVersion = await provider.send("net_version", []);
if (netVersion !== "8453") {
  console.error("Not connected to Base mainnet!");
}

  2. Multi-Chain Applications Use the network ID to adapt your application's behavior based on the connected network.
