What are viem's main functionalities?

Connecting to Ethereum Nodes

This feature allows you to create a client that connects to an Ethereum node using a specified URL. In this example, the client connects to the Infura mainnet node.

const { createClient } = require('viem');
const client = createClient({
  url: 'https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID'
});

Sending Transactions

This feature allows you to send transactions on the Ethereum network. The example demonstrates sending 1 ETH from one address to another.

const { sendTransaction } = require('viem');
const tx = await sendTransaction(client, {
  from: '0xYourAddress',
  to: '0xRecipientAddress',
  value: '1000000000000000000' // 1 ETH in wei
});

Interacting with Smart Contracts

This feature allows you to interact with smart contracts by calling their functions. The example shows how to call a function of a smart contract using its ABI and function name.

const { callContractFunction } = require('viem');
const result = await callContractFunction(client, {
  contractAddress: '0xContractAddress',
  abi: [
    // ABI of the contract
  ],
  functionName: 'functionName',
  args: [/* function arguments */]
});
