Common ABIs

To help make developing your dApps easier, we include a set of pre-built ABIs for common contracts. These ABIs can be used directly with the useContract hook, and easily extended.

ERC-20

The ABI for ERC-20 tokens is provided.

import { ERC20_ABI, useContract } from "ethereal-react";

const contract = useContract(address, ERC20_ABI);

ERC-721

The ABI for ERC-721 tokens is provided, and includes common extensions for token metadata as well.

import { ERC721_ABI, useContract } from "ethereal-react";

const contract = useContract(address, ERC721_ABI);

Extending ABIs

The exported ABIs are arrays, and as such can be extended by spreading it into another array. For example, if you have an ERC721 token with a mint method, you could create the ABI as follows:

import { ERC721_ABI } from "ethereal-react";

const MintableERC721 = [
  // Copy all of the ERC721 ABIs:
  ...ERC721_ABI,
  // Add the `mint()` function:
  "function mint()",
];
