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

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。


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:

  1. duncanwang@ubuntu:~/work/opensea-creatures$ truffle compile
  2. Please set a mnemonic and infura key.
  3. Compiling ./contracts/Creature.sol...
  4. Compiling ./contracts/CreatureFactory.sol...
  5. Compiling ./contracts/CreatureLootBox.sol...
  6. Compiling ./contracts/DeployCreature.sol...
  7. Compiling ./contracts/Factory.sol...
  8. Compiling ./contracts/Migrations.sol...
  9. Compiling ./contracts/Strings.sol...
  10. Compiling ./contracts/TradeableERC721Token.sol...
  11. Compiling openzeppelin-solidity/contracts/AddressUtils.sol...
  12. Compiling openzeppelin-solidity/contracts/introspection/ERC165.sol...
  13. Compiling openzeppelin-solidity/contracts/introspection/SupportsInterfaceWithLookup.sol...
  14. Compiling openzeppelin-solidity/contracts/math/SafeMath.sol...
  15. Compiling openzeppelin-solidity/contracts/ownership/Ownable.sol...
  16. Compiling openzeppelin-solidity/contracts/token/ERC721/ERC721.sol...
  17. Compiling openzeppelin-solidity/contracts/token/ERC721/ERC721Basic.sol...
  18. Compiling openzeppelin-solidity/contracts/token/ERC721/ERC721BasicToken.sol...
  19. Compiling openzeppelin-solidity/contracts/token/ERC721/ERC721Receiver.sol...
  20. Compiling openzeppelin-solidity/contracts/token/ERC721/ERC721Token.sol...
  21. Compilation warnings encountered:
  22. ...
  23. function baseTokenURI() public view returns (string) {
  24. ^ (Relevant source part starts here and spans across multiple lines).
  25. Writing artifacts to ./build/contracts

2.3 配置.env环境变量

.env的配置内容参考:

  1. mnemonic_ropsten=mosquito electric slim hybrid craft charge shrimp digital car wonder term oven
  2. mnemonic_rinkeby=mosquito electric slim hybrid craft charge shrimp digital car wonder term oven
  3. mnemonic_mainnet=
  4. NETWORK="rinkeby"
  5. INFURA_KEY="8ce5ebd357144bef8dceae3de1915e29"
  6. MNEMONIC="mosquito electric slim hybrid craft charge shrimp digital car wonder term oven"
  7. OWNER_ADDRESS=""
  8. NFT_CONTRACT_ADDRESS=""
  9. 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/。
(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】
```
duncanwang@ubuntu:~/work/opensea-creatures$ truffle migrate —network rinkeby —reset —compile-all

  1. **【说明】**
  2. 所以,对应的生物合约creature的交易地址为https://rinkeby.etherscan.io/tx/0x636f9f4060142298518a36fec820c7b6de1d123342108cd7cf142752cbc17617
  3. 和合约地址为 0x6f155409060919c3035727fd88f437c2d0a83d1a
  4. ## 2.5 配置.env环境和更新ABI
  5. 更新.env文件参数。
  6. OWNER_ADDRESSERC721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”

  1. 修改mint_test.jsNFT_ABItruffle框架编译文件Creature.jsonJSON内容。

```
输入合约地址,可见已创建了12个ERC721的资产。
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。

3.参考

1)英文文档导航
2)在 rinkeby上发然后去opensea登记
