useContract()

Use it to get a viem's contract instance.

WARNING

This hook is still in early development and currently only works with EVM-compatible wallets, allowing interaction with contract instances via JSON-RPC.

Usage

import { useContract } from '@buidlerlabs/hashgraph-react-wallets'
import { contractABI } from './ABIs'

const App = () => {
  const contract = useContract({
    address: '0x123...321',
    abi: contractABI
  })


  // do stuff

  return ...
}

Parameters

interface IUseContractProps<Connector> {
  connector?: Connector | null
  abi: Abi
  address: `0x${string}`
  autoFetch?: boolean
}
