部署tron 721细节：
1.由于此代码限制：
1.每次部署时需要先把NFT数据写入合约
2.每次部署只能写入1个NFT素材
3.需要多种素材或者多个类型需要部署不同合约
5.上传.json格式素材需要去掉.json

Remix 工具部署及调用 Web3 ERC721 合约

1.介绍
web3 ERC721 是指根据以太坊web3发布的 ERC721 合约，目前公司常用相关链有：以太坊，FXEVM,BSC,POLYGON,TRON,AVAC等等，链相关地址都是0x开头
2.部署工具：
https://remix.ethereum.org/

部署流程：
生成合约
1.remix新建文件夹和.sol文件，粘贴合约代码

进入编译页面，选择合约对应版本，勾选自动编译，点击编译合约

小狐狸选择对应链，地址(看你想部署到什么链)，remix进入生成合约页面，选择injected web3 连接小狐狸，连接后下方展示连接地址的金额和链ID

打开生成合约的交易面板

生成token合约
