Send all Tokens and Eth to a Address automatically

Question

I have few child wallets and a parent wallet. Whenever these child wallets get incoming ERC20 tokens or ETH. I want to send them automatically to the parent wallet.

I know I can do below to send the entire eth balance.

beneficiary.transfer(this.balance);

How can I do it for erc20 tokens.

Answer 1

require(token.transfer(beneficiary, token.balanceOf(this)));

where token is the ERC20 token you're transferring. E.g.:

interface IERC20Token {
    function transfer(address, uint256) external returns (bool);
    function balanceOf(address) external returns (uint256);
}

contract Foo {
    IERC20Token token = IERC20Token(0x123abc...);

    function doit(address beneficiary) public {
        require(token.transfer(beneficiary, token.balanceOf(this)));
    }
}
