Building with Viem: A Web3 Developer's Journey

import { createPublicClient, http } from 'viem'
import { mainnet } from 'viem/chains'
const client = createPublicClient({
  chain: mainnet,
  transport: http()
})

import { formatUnits } from 'viem'
async function getTokenBalance(address: string, tokenAddress: string) {
  const balance = await client.readContract({
    address: tokenAddress,
    abi: erc20Abi,
    functionName: 'balanceOf',
    args: [address]
  })
  
  return formatUnits(balance, 18)
}

Web3 development has evolved rapidly, and with it, the tools we use to build decentralized applications. Today, I want to share my experience with viem, a TypeScript interface for Ethereum that's changing how we interact with the blockchain.

Why Viem?

Coming from ethers.js, I was initially skeptical about switching to a new library. However, viem's approach to type safety and developer experience quickly won me over.

> Viem provides excellent TypeScript support out of the box. No more guessing what parameters a function expects.

Key Benefits

> The migration wasn't without challenges, but the improved developer experience made it worthwhile.
