useTokenDecimals

Hook for fetching the decimals of an ERC20 token.

Tokens usually opt for a value of 18 , imitating the relationship between Ether and Wei. Therefore, 18 is the default value returned by this function, unless your ERC20 contract explicitly overrides it.

import { useTokenDecimals, useContract } from "@thirdweb-dev/react";
 
function App() {
  const { contract } = useContract(contractAddress, "token");
  const { data, isLoading, error } = useTokenDecimals(contract);
}
