在ERC721中，有3种提供NFT传输的方法：

function safeTransferFrom(address _from, address _to, uint256 _tokenId, bytes data) external payable;
function safeTransferFrom(address _from, address _to, uint256 _tokenId) external payable;
function transferFrom(address _from, address _to, uint256 _tokenId) external payable;

简而言之，您想做的就是处理上述方法中的费用。最简单的方法是从呼叫者那里收取费用，因为应付所有3种方法。

uint256 fee = 0.1 ether;
function transferFrom(address _from, address _to, uint256 _tokenId) external payable{
    require(msg.value >= fee, "sent ether is lower than fee")
    // your erc721 implementation
}

In ERC721, there are 3 methods that provide NFT transfer:

function safeTransferFrom(address _from, address _to, uint256 _tokenId, bytes data) external payable;
function safeTransferFrom(address _from, address _to, uint256 _tokenId) external payable;
function transferFrom(address _from, address _to, uint256 _tokenId) external payable;

Simply, what you would want to do is handle fees in the above methods. The most simplistic approach would be to collect the fee from caller, since all 3 methods are payable.

uint256 fee = 0.1 ether;
function transferFrom(address _from, address _to, uint256 _tokenId) external payable{
    require(msg.value >= fee, "sent ether is lower than fee")
    // your erc721 implementation
}
