Send transaction with smart contract

Question

is it possible to send transactions to an address from the smart contract without having to confirm the transaction on metamask? I mean, I need a certain condition to start a transaction that sends coins to a wallet, but I can't make it automatic without my confirmation.

is it possible to do what i ask? Thank you

ps i am using js and web3

Answer 1

Yes, it's possible.

First thing: import IERC20 smart contract in your contract

1. You declare the address: address public toSend;

2. You approve the address to spend tokens using approve function:

function approve(address spender, uint256 amount) public virtual override returns (bool) {
                _approve(_msgSender(), spender, amount);
                return true;
        
        }

and call it like that:

approve(toSend, amount);

3. Send the tokens using transfer function

   function transfer(address recipient, uint256 amount) public virtual override returns (bool) { _transfer(_msgSender(), recipient, amount); return true; }

you will call it transfer(toSend, amount)

P.s. If you want ot do that from a web interface please check ether.js documentation
