我有这个我想在 Polygon Network 中铸造的地址列表：

所有地址都是有效的，原因是：

/**
 * Checks if the given string is an address
 *
 * @method isAddress
 * @param String address the given HEX adress
 * @return Boolean
 */
var isAddress = function (address) 
  if (!/^(0x)?[0-9a-f]40$/i.test(address)) 
    // check if it has the basic requirements of an address
    return false;
   else if (/^(0x)?[0-9a-f]40$/.test(address) || /^(0x)?[0-9A-F]40$/.test(address)) 
    // If it's all small caps or all all caps, return true
    return true;
   else 
    // Otherwise check each case
    return isChecksumAddress(address);
  
;

/**
 * Checks if the given string is a checksummed address
 *
 * @method isChecksumAddress
 * @param String address the given HEX adress
 * @return Boolean
 */
var isChecksumAddress = function (address) 
  // Check each case
  address = address.replace('0x','');
  var addressHash = sha3.keccak256(address.toLowerCase());
  for (var i = 0; i < 40; i++ ) 
    // the nth letter should be uppercase if the nth digit of casemap is 1
    if ((parseInt(addressHash[i], 16) > 7 && address[i].toUpperCase() !== address[i]) || (parseInt(addressHash[i], 16) <= 7 && address[i].toLowerCase() !== address[i])) 
      return false;
    
  
  return true;
;

但我仍然收到以下错误：

PATCH /smart/airdrop/polygon Error: execution reverted: ERC721: transfer to non ERC721Receiver implementer
0x08c379a0000000000000000000000000000000000000000000000000000000000000002000000000000000000000000000000000000000000000000000000000000000324552433732313a207472616e7366657220746f206e6f6e20455243373231526563656976657220696d706c656d656e7465720000000000000000000000000000

【参考方案1】：

您使用的地址是有效的，但在您使用的 erc721 合约版本中（我不确定这种行为在 openzeppelin 合约版本 4 中是否发生了变化）以便在合约应该已经实现了这个https://docs.openzeppelin.com/contracts/3.x/api/token/erc721#IERC721Receiver，以防止代币被锁定在合约中

【讨论】：

我创建的智能合约确实实现了这一点，问题是我想要铸造 ERC721 的地址可能不是用户有效地址。问题是我如何在尝试造币之前验证这一点。
