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 ^0.7.0;
import "eth-token-recover/contracts/TokenRecover.sol";
contract MyContract is TokenRecover {
// your stuff
}
Code
This repo contains:
Contract has a recoverERC20
function that transfers a tokenAmount
amount of tokenAddress
token to the contract owner.
function recoverERC20(address tokenAddress, uint256 tokenAmount) public onlyOwner;
Note: only owner can call the recoverERC20
function so be careful when use on contracts generated from other contracts.
