Features

  • Abstractions over the JSON-RPC API to make your life easier
  • First-class APIs for interacting with Smart Contracts
  • Language closely aligned to official Ethereum terminology
  • Import your Browser Extension, WalletConnect or Private Key Wallet
  • Browser native BigInt, instead of large BigNumber libraries
  • Utilities for working with ABIs (encoding/decoding/inspection)
  • TypeScript ready (infer types from ABIs and EIP-712 Typed Data)
  • First-class support for Anvil, Hardhat & Ganache
  • Test suite running against forked Ethereum network

... and a lot more.

Overview

// 1. Import modules.
import { createPublicClient, http } from 'viem';
import { mainnet } from 'viem/chains';

// 2. Set up your client with desired chain & transport.
const client = createPublicClient({
  chain: mainnet,
  transport: http(),
});
