## 1\. 摘要

《第三十三课 如何创建自己的ERC721非同质化资产生物商店？》讲解了如何使用REMIX本地环境搭建ERC721非同质化资产生物商店，因为合约相对复杂，采用solidity import多级合约编辑的方式。
本文采用TRUFFLE框架的形式来发布建ERC721非同质化资产生物商店的内容，以便后续js脚本扩展和DAPP开发。
本文包括内容：
（1）环境准备
（2）智能合约编译
（3）配置.env环境变量
（4）智能合约部署到rinkeby测试网
（5）配置.env环境和更新ABI
（6）创建ERC721资产

辉哥系统整合出了ERC721从理论到实践的文章，可按需查看：

## 2\. 内容

### 2.1 环境准备

ERC721的智能合约就采用OpenZeppelin的ERC721模板合约。
具体的代码架构和分析辉哥就不展示了，有需要源码工程的同学可直接加入辉哥的知识星球下载。

![](https://img.learnblockchain.cn/2020/02/01_/789208183.png)

然后在Ubuntu环境建把工程文件复制过去。

### 2.2 智能合约编译

编译成功结果：

```
duncanwang@ubuntu:~/work/opensea-creatures$ truffle compile
Please set a mnemonic and infura key.

Compilation warnings encountered:
...
  function baseTokenURI() public view returns (string) {
  ^ (Relevant source part starts here and spans across multiple lines).

Writing artifacts to ./build/contracts

```

### 2.3 配置.env环境变量

.env的配置内容参考：

```
mnemonic_ropsten=mosquito electric slim hybrid craft charge shrimp digital car wonder term oven
mnemonic_rinkeby=mosquito electric slim hybrid craft charge shrimp digital car wonder term oven
mnemonic_mainnet=
NETWORK="rinkeby"
INFURA_KEY="8ce5ebd357144bef8dceae3de1915e29"
MNEMONIC="mosquito electric slim hybrid craft charge shrimp digital car wonder term oven"
OWNER_ADDRESS=""
NFT_CONTRACT_ADDRESS=""
FACTORY_CONTRACT_ADDRESS=""

```

其中，
（1）mnemonic_ropsten,mnemonic_rinkeby，MNEMONIC为你的metaMask钱包助记词，可以从metaMask钱包导出。记得从ropsten，rinkeby测试网水龙头网址申请一点测试ETH。请不要用辉哥的助记词哦。
（2）INFURA_KEY为你在infura网络申请的KEY，申请地址为 [https://infura.io/](https://infura.io/) 。
（3）NFT_CONTRACT_ADDRESS在部署后才可以获取。

### 2.4 智能合约部署到rinkeby测试网

运行命令：

> truffle migrate --network rinkeby --reset --compile-all
> 【成功运行结果】

```

```

**【说明】**
所以，对应的生物合约creature的交易地址为 [https://rinkeby.etherscan.io/tx/0x636f9f4060142298518a36fec820c7b6de1d123342108cd7cf142752cbc17617](https://rinkeby.etherscan.io/tx/0x636f9f4060142298518a36fec820c7b6de1d123342108cd7cf142752cbc17617)
和合约地址为 0x6f155409060919c3035727fd88f437c2d0a83d1a

### 2.5 配置.env环境和更新ABI

更新.env文件参数。
OWNER_ADDRESS为ERC721生物商店需要归属的以太坊地址，NFT_CONTRACT_ADDRESS为刚才编译成功的creature合约地址。

```
OWNER_ADDRESS="0xD1F7922e8b78cBEB182250753ade8379d1E09949"
NFT_CONTRACT_ADDRESS="0x6f155409060919c3035727fd88f437c2d0a83d1a"

```

修改mint_test.js的NFT_ABI为truffle框架编译文件Creature.json的JSON内容。

### 2.6 创建ERC721资产

> node scripts/mint_test.js

【运行成功结果】

```

输入合约地址，可见已创建了12个ERC721的资产。
[https://rinkeby.etherscan.io/address/0x6f155409060919c3035727fd88f437c2d0a83d1a](https://rinkeby.etherscan.io/address/0x6f155409060919c3035727fd88f437c2d0a83d1a)

### 2.7 发布生物商店

参考《第三十三课 如何创建自己的ERC721非同质化资产生物商店？》文章，在 [https://rinkeby.opensea.io/get-listed/step-two](https://rinkeby.opensea.io/get-listed/step-two) 地址输入智能合约地址，导入items后，就可以看到OpenSea的店铺了。
本案例使用的智能合约地址为0x6f155409060919c3035727fd88f437c2d0a83d1a
创建成功后，进入账号可以看到该智能合约对应的海洋生物商店。
