Allows the contract owner to recover any ERC20 token sent into the contract for error

ETH Token Recover

TokenRecover allows the contract owner to recover any ERC20 token sent into the contract for error.

Motivation

There are lots of tokens lost forever into Smart Contracts (see OMG token balances). Each Ethereum contract is a potential token trap for ERC20 tokens. They can't be recovered so it means money losses for end users.

Install

npm install eth-token-recover

Usage

pragma solidity ^0.8.0;

import "eth-token-recover/contracts/TokenRecover.sol";

contract MyContract is TokenRecover {
  // your stuff
}

Code

This repo contains:

• TokenRecover.sol

Contract has a recoverERC20 function that transfers a tokenAmount amount of tokenAddress token to the contract owner.

function recoverERC20(address tokenAddress, uint256 tokenAmount) public virtual onlyOwner;

Note: only owner can call the recoverERC20 function so be careful when use on contracts generated from other contracts.
