The 'viem' npm package is a versatile library designed for interacting with Ethereum blockchain networks. It provides a range of functionalities including connecting to Ethereum nodes, sending transactions, interacting with smart contracts, and more.
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 */]
});The 'web3' package is a popular library for interacting with the Ethereum blockchain. It provides similar functionalities to 'viem' such as connecting to nodes, sending transactions, and interacting with smart contracts. However, 'web3' is more established and widely used in the Ethereum developer community.
The 'ethers' package is another widely-used library for Ethereum development. It offers a clean and simple API for interacting with the Ethereum blockchain, including functionalities for connecting to nodes, sending transactions, and interacting with smart contracts. 'ethers' is known for its ease of use and comprehensive documentation.

... and a lot more.
// 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(),
});
// 3. Consume an action!
const blockNumber = await client.getBlockNumber();
