I have created the following ERC721 contract:
pragma solidity ^0.6.0; import "@openzeppelin/contracts-upgradeable/token/ERC721/ERC721PausableUpgradeable.sol"; import "@openzeppelin/contracts-upgradeable/access/OwnableUpgradeable.sol"; contract MyNFT is ERC721PausableUpgradeable, OwnableUpgradeable { // keep the order of Status enum Status { Start, End} mapping (uint256 => Status) private status; string private constant MY_URI = "www.abc.com/metadata/start.json"; function initialize() initializer public { __ERC721_init_unchained("MyNFT", "MNFT"); __Ownable_init_unchained(); } function mint(address to, uint256 tokenId) public onlyOwner { _mint(to, tokenId); status[tokenId] = Status.Start; _setTokenURI(tokenId, MY_URI); } . . . And I've tried the same with a plain-vanilla ERC721 as well:
// SPDX-License-Identifier: MIT pragma solidity ^0.6.0; import "@openzeppelin/contracts/token/ERC721/ERC721.sol"; contract MyNFT is ERC721 { constructor(string memory name_, string memory symbol_) ERC721(name_, symbol_) public { } function mint(address holder, uint256 tokenId) public { _safeMint(holder, tokenId); } } Then on Ropsten I mint a token to my Coinbase Wallet address (Ropsten). However, I can't see my ERC721 under "Collectibles" in the Coinbase Wallet, although I can see in in the console. Does anyone have an advice how to make the ERC721 visible in Coinbase Wallet? ERC20 tokens I can see. The same problems applies for both ERC721 contract version, for the upgradeable as well as for the plain-vanilla ERC721.
Is something special required for Coinbase wallets?
