safeTransferFrom does not transfer etherium to the target ERC-721

Question

I create a contract with ERC-721 and I try to transfer the token with money. I am using web3.js and openzeppelin. So, The transaction is confirmed, but no money is sent to the target wallet.

Here is the contract buy function;

function buy(uint256 _tokenId) public payable { address buyer = msg.sender; require(_isApprovedOrOwner(msg.sender, _tokenId), "ERC721: transfer caller is not owner nor approved"); approve(buyer, _tokenId); safeTransferFrom(ownerOf(_tokenId), buyer, _tokenId); }

And here is web3.js :

const buy = (2,2) => { //Token ID: 2 //Price: 2 ether contract.methods.buy(2).send({ from: account, value: web3.utils.toWei(2, 'ether') }) }

Please help me. Thank you.

Answer 1

I changed my contract buy function like this;

function buy(uint256 _tokenId, address payable _owner, uint256 _amount) public payable { address payable buyer = msg.sender; address payable owner = _owner; //<-- *payable (important) _transfer(ownerOf(_tokenId), buyer, _tokenId); owner.transfer(_amount); //<--- this function send the amount to the token owner. }

This helped in solving the problem!
