# WaterMargin
Create a cyberpunk Water Margin, also an inheritage of Chinese cultural treasures, by combining Web3 technology and traditional culture. An NFT is minted to represent one of the 108 characters of water Margin. Different characters delegate different communal roles of NFT holders. The NFT is integrated with DAO management to motivate members to continuously contribute to open source community.

## how to start
- install node_modules
```shell
cd Dapp-Learning-WaterMargin
yarn
```
- config environment
```shell
cd packages/hardhat
cp .env.example .env
PRIVATE_KEY=xxxxxxxxxxxxxxxx
PROJECT_ID=yyyy
PROJECT_SECRET=ZZZZ
```
- upload images to IPFS
```shell
cd Dapp-Learning-WaterMargin
yarn upload
```
- set MerkleList
因为 DappLearningCollectible 使用了 Merkle 空投方式, 在部署前需要设置空投的地址, 以便后续进行测试使用.
修改 packages/hardhat/scripts/addressList.json 文件, 在其中设置需要空投的地址
- deploy contract
目前主合约为 DappLearningCollectible, 拍卖合约使用 AuctionFixedPrice.
执行部署命令后, 合约自动部署在 matic 测试网路上, 并发布 ABI 到 react-app/src/contracts 下面. 如果需要部署到其他的测试网路, 需要需改 hardhat/hardhat.config.js 中的 defaultNetwork. packages/hardhat/test/MerkleDrop.test.js 为 Merkle 空投的测试脚本
```shell
cd Dapp-Learning-WaterMargin
yarn deploy
```
- replance WETH address and addressList.json
当前竞拍的所使用的标的资产是 ERC20, 为了方便, 同时能适配其他的网络, 需要进行 WETH 地址的替换.
执行如下 replace 命令, 即可替换 react-app/src/contracts/WETH.address.js 中 WETH 的地址, 以及 react-app/src/utils/addressList.json 文件
```shell
cd Dapp-Learning-WaterMargin
yarn replace
```
- deploy subgraph
通过 thegraph 部署的 subgrpah 只能部署在主网 和 rinkeby 网络, 如果需要使用其他的网络, 则需要自己搭建 graph 服务. 下面讲解下如何通过 thegraph 部署 subgraph - 创建 subgraph
在 thegraph 官网上创建一个 subgraph, 假设 subgraph 名字为 DappLearningCollectible
- install graph-cli
```shell
yarn global add @graphprotocol/graph-cli
```
- init subgraph
```shell
graph init --studio DappLearningCollectible
## 在选择网络的时候选择 rinkeby
```
- subgraph certification
```shell
graph auth --studio fc72b2●●●●●●●●476024
```
- copy and modify config file
复制 dapp-learning-test/src/mapping.ts , dapp-learning-test/schema.graphql , dapp-learning-test/subgraph.yaml 到对应的目录下, 同时修改如下配置
```shell
## subgraph.yaml 中的 address 和 startBlock
source:
address: "0xe1f5CCe0e39E6F3Fec75D29BCb32821A98d8b432"
abi: DappLearningCollectible
startBlock: 9737148
## mappting.ts 中的 auctionAddr
const auctionAddr = Address.fromHexString(
"0xAE8FF5372fE7beb7eBC515ebe19670afd9045bf0"
);
```
- compile files
```shell
cd DappLearningCollectible
graph codegen && graph build
```
- deploy
```shell
graph deploy --studio DappLearningCollectible
```
- get graph URL
graph depoloyed, then get info.
```shell
Subgraph endpoints:
Queries (HTTP): https://api.studio.thegraph.com/query/1542/dapp-learning-test/v0.1.0
Subscriptions (WS): https://api.studio.thegraph.com/query/1542/dapp-learning-test/v0.1.0
```
- copy environment variables
```shell
cd react
cp .env.example .env
## 然后在其中配置 REACT_APP_PROVIDER 和 REACT_APP_GRAPHQL, 其中 REACT_APP_GRAPHQL 值为上一步 graph 部署成功后显示的值
REACT_APP_PROVIDER
REACT_APP_GRAPHQL
```
- start react
```
yarn start
```
- Mint NFT
只有在 packages/hardhat/scripts/addressList.json 文件中的账户地址才能进行 Mint 操作.
- 拍卖
查看 Auction 合约中的 createTokenAuction 方法, 即拍卖方法, 可以发现其中调用了 IERC721(\_nft).safeTransferFrom(owner, address(this), \_tokenId), 即用户在执行拍卖前需要对 Auction 合约进行 NFT 的 approve 授权
```
function createTokenAuction(
address _nft,
uint256 _tokenId,
address _tokenAddress,
uint256 _price,
uint256 _duration
) external {
require(msg.sender != address(0));
require(_nft != address(0));
require(_price > 0);
require(_duration > 0);
auctionDetails memory _auction = auctionDetails({
seller: msg.sender,
price: _price,
duration: _duration,
tokenAddress: _tokenAddress,
isActive: true
});
address owner = msg.sender;
IERC721(_nft).safeTransferFrom(owner, address(this), _tokenId);
tokenToAuction[_nft][_tokenId] = _auction;
emit StartAuction(owner, _tokenId, _price, _duration);
}
```
- 购买
同理在 purchaseNFTToken 接口, 即购买接口中, 会调用 IERC20(auction.tokenAddress).transferFrom(msg.sender,seller,price) , 即用户需要对 Auction 合约进行 ERC20 的 approve 授权, 这里是调用 WETH 的 approve 对 Auction 合约进行授权
```
function purchaseNFTToken(address _nft, uint256 _tokenId) external {
auctionDetails storage auction = tokenToAuction[_nft][_tokenId];
require(auction.duration > block.timestamp, "Deadline already passed");
//require(auction.seller == msg.sender);
require(auction.isActive);
auction.isActive = false;
address seller = auction.seller;
uint price = auction.price;
require(IERC20(auction.tokenAddress).transferFrom(msg.sender,seller,price), "erc 20 transfer failed!");
IERC721(_nft).safeTransferFrom(address(this),msg.sender , _tokenId);
emit AuctionEnd(seller, msg.sender, _tokenId, price, auction.duration);
}
```
