wagmi-extended

Wagmi hooks extending base functionality

Overview

wagmi-extended is a library that extends the functionality of the base wagmi hooks, providing additional utilities for interacting with Ethereum smart contracts in a React environment. This library is designed to simplify the process of writing to contracts by offering a more flexible API.

Installation

To install wagmi-extended, you can use:

npm:

npm install @nejcm/wagmi-extended

yarn:

yarn add @nejcm/wagmi-extended

Usage

Example: Using useWriteContract

The useWriteContract hook allows you to interact with Ethereum smart contracts by writing data to them. Below is an example of how to use this hook:

import { useWriteContract } from 'wagmi-extended';
import erc20Abi from './erc20Abi.json';

const MyComponent = () => {
  const { writeContract, writeContractAsync } = useWriteContract({
    writeProps: {
      address: '0x0000000000000000000000000000000000000000',
      abi: erc20Abi,
      functionName: 'approve',
    },
  });

  const handleWrite = async () => {
    try {
      await writeContract({
        args: ['0x0000000000000000000000000000000000000000', BigInt(1000)],
      });
      console.log('Transaction successful');
    } catch (error) {
      console.error('Transaction failed', error);
    }
  };

  const handleWriteOverride = async () => {
    try {
      await writeContract({
        // Allows overriding the default writeProps
        address: '0x0000000000000000000000000000000000000001',
        functionName: 'revoke',
        args: ['0x0000000000000000000000000000000000000000', BigInt(1000)],
      });
      console.log('Transaction successful');
    } catch (error) {
      console.error('Transaction failed', error);
    }
  };

  return <button onClick={handleWrite}>Approve</button>;
};

API

useWriteContract

• Parameters: Accepts default useContractWrite props and an additional optional object with the following properties:

  • writeProps: An optional object containing:
    • address: Optional contract address.
    • abi: Optional contract ABI.
    • functionName: Optional name of the function to call.
    • args: Optional arguments for the function.
    • chainId: Optional chain ID.

• Returns: Return type is the same as the default useContractWrite hook with the following two methods overridden to allow optional arguments:

  • writeContract: A function to execute the contract write operation.
  • writeContractAsync: An async version of writeContract.

TODO

• Add more useful overrides and functionality
  • Batch transaction support
  • ...
