useContract

This hook is the foundation for many other hooks in useink. It returns a ChainContract<T> type and will automatically set the RPC url for the chain you specify.

Usage​

import { useContract } from 'useink'

const CONTRACT_ADDRESS = '..'
const ALEPH_CONTRACT_ADDRESS = '..'

export const MyContractView: React.FC = () => {
  // The default chain will be used if you omit chainId as the third argument
  // The default chain is the first item in the chain config for UseInkProvider
  const contract = useContract(CONTRACT_ADDRESS, metadata)
  const alephContract = useContract(ALEPH_CONTRACT_ADDRESS, metadata, 'aleph')

  // use with other hooks...
  // e.g. useCall, useCallSubscription, useTx, etc

  return null
}

Return Value​

{
  // A contract object that contains metadata, and an api client set with a specific RPC url
  contract: ChainContract<T>, 
  // A strongly typed chain name found in `useink/chains`
  chainId: ChainId,
} | undefined
