BNB Sidechain
How to
Deploy an ERC-721 Token

Deploy ERC-721 token

Deployment of ERC-721 token can be done though Remix IDE of locally using truffle. Since BNB Sidechain has EVM & Web3 support, it is compatible with Ethereum development toolsets. Remix is the easiest way to deploy the ERC-721 smart contract into a BNB Sidechain network.

To deploy an ERC-721 token using Remix IDE go to the remix page (opens in a new tab). In the deploy section choose Injected Web3 and make sure your MetaMask is connected to one of the BNB Sidechain networks. To get connected to the BNB Sidechain network, go to one of the BNB Sidechain devnet's staking pages, for example, (opens in a new tab), and it will create a new MetaMask network automatically for you. You can also configure your MetaMask manually.

Use this snippet from the ERC-721 smart contract:

// SPDX-License-Identifier: GPL-3.0
pragma solidity ^0.8.1;

import "@openzeppelin/contracts/token/ERC721/extensions/ERC721URIStorage.sol";
import "@openzeppelin/contracts/utils/Counters.sol";
import "@openzeppelin/contracts/access/Ownable.sol";

contract MyERC721Token is ERC721URIStorage, Ownable {
    using Counters for Counters.Counter;
    Counters.Counter private _tokenIds;

    constructor() ERC721("MyERC721Token", "Test Token") {}

    function mintNFT(address recipient, string memory tokenURI)
        public onlyOwner
        returns (uint256)

        uint256 newItemId = _tokenIds.current();
        _mint(recipient, newItemId);
        _setTokenURI(newItemId, tokenURI);

        return newItemId;

MetaData URI is a link (usually on ipfs) that returns a JSON object with information about your NFT token.
