如何检查地址是否允许接收ERC721？

Question

I have this list of address that I want to mint in Polygon Network:

["0x8d520d016246f31fe7a676648f1fd5e55ec5562d","0x5a52b317ed280c90d903d9605c2f41acbbc4b066","0x1bd7dabaae1b0d3f82cb47e182502b019f796b1c","0x35c81e79e1c49718db71b95179600e8c2472571d","0x4675e69560d9750a3682944a9dfa1b4fe3cda279","0x101a036ba89748a2c05431c7b088342758d38ab5","0x2bcc25c0cc7c8bb097b58b076b68574483af2985","0x55c052df9d0238a77dbf40931c26409c60955ff3","0x9024f7a9159e76b90029e0964f74d69d2b34c1a2","0x6441303870f67bbc3bb9665c6e951ed501d16233","0x2433ec4e8b0878ac4d7c7bf56e1fdf2b8977b06d","0x45d4bd22ca029d805cf971a2a53f884666e916df","0xbe6e3669464e7db1e1528212f0bff5039461cb82","0xd8dfba40a13df7f9270154bf13b293b732fea1f0","0x4772c5be232ba11daf20c1985c02338b0f8f871a","0xa691ea9bb77464c0a7def21a175a7d281dd44a0e","0x32619ea96a1260e7215bd71b711882769d5b3dc3","0xa28872727a46b0827527fb04540f52933db577ed","0x841ce48f9446c8e281d3f1444cb859b4a6d0738c","0xe7f80963f9ec6c449a120b68cae5571f87237e41","0xf7fbf80fa09975042ef620e8d6ef54af8bf2cc46","0xeb21e84c68d8e9fb4371e3b3686ecdf5e81de689","0x661d3005506aea3def4422606b1a31be9cef1d80","0xef9702ea316e52b4e771ef3ba81930320c4b88e6","0x4e3144dcd9b91a6acd7ea238afb74fb789fcd03a","0xf7b30915db932ec94e04a7f0208a63cc8eb87aa9","0x0c3d5fb65c2bdf9aaffc420303c523b55c3dca6c","0x16f33b3d0272f897d9bc55282fa151215215602c","0x4081c28448038d4eca175e89312c174fdf9c6a0d","0x22475406fa38e0747d88766dc38417ecc73e4adf","0xc22f5b5ccf5c718582460e6450391f738fdaf005","0xab25a1276b9fa7e2cb64b6e858cdc35d71213e48","0xc830cf22bbb93f5eaf380496054f74d497499cec","0x9619d3fa1f29c1de8fcfacedc07321637c1f0c3b","0x961c90b02232c2678eaf864627eaa20438d70ef2","0xfbb6aa0ba4a9ee610b9f0fea384e9d597c676a5f","0x4327342ccc2b7dd74751a5193ceb36ba5ce33567","0xcd5e2f67325d01bf4d9535a939428e2d8dab261d","0x81513aedaf902b0024168616de85361e5ff9cc28","0x166ed9f7a56053c7c4e77cb0c91a9e46bbc5e8b0","0x57043ee3d107de959e55e6932892874623fc961d","0x2831c1a4bbf6d7f5af915f0e09767a0463e12cfa","0x6a4d2b58a53b2dc960be1a888f279426a97b847f","0xd5f6f246507ffa6191c9d1851474dfe1782c5d25","0xc40bdf4aa875b6104381901e064f16bcb775789f","0xebb2db2d6c51a68bdee10470fe994fe3a4e53d23","0xd39a43b25f38e1ff7ec48420bff88743386688d6","0xfe03ea2901ffc6db88e7dc2410b0e98dff8f50ab","0x726dd921b64ebd09318e827d13f28047aa4a18d2","0xd46b4d81aa6764d00e61ee217a4f5cecd9aa189b"]

All the address are valid, due to:

/**
 * 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;
};

But I still get the following error:

Answer 1

The address that you are using are valid, but in the version of the erc721 contract that you are using (I'm not sure is this behavior has changed in the version 4 of openzeppelin contracts) in order to receive an erc721 in a contract the contract should have implemented this https://docs.openzeppelin.com/contracts/3.x/api/token/erc721#IERC721Receiver , in order to prevent tokens being locked in contracts
