Uniswap V4 Hook Deployment & Use cases

1. Run Uniswap V4 built-in tests

In Uniswap V4 core repo:

npx hardhat test

2. Compile pool and hook contracts

In Our Uniswap v4 periphery repo:

npx hardhat compile

Move the required ABI files from artifacts/contracts to SDK repo scripts/frontend/abi.

3. Deploy pool and hook contracts

In Our Uniswap V4 SDK repo:

1. Start a local blockchain node

   npx hardhat node

2. Deploy Uniswap V4 core contracts

3. Configure blockchain networks, wallet, and contract addresses in:
   scripts/config.ts

4. Run the hook deployment script:

   npx hardhat run scripts/depoly/depoly.ts

   • Limit Order Hook: contracts/LimitOrder.sol
   • Dynamic Fee Hook: contracts/DynamicFee.sol

4. Initialize the PoolManager contract

Run the initialization script:

npx hardhat run scripts/frontend/init/init.ts

5. Contract interactions

5.1 Trading at Market Price

• Add liquidity:

  npx hardhat run scripts/frontend/marketprice/addLiquidity.ts

• Swap:

  npx hardhat run scripts/frontend/marketprice/swap.ts

• Remove liquidity:

  npx hardhat run scripts/frontend/marketprice/removeLiquidity.ts

5.2 Trading of Limit Order

(Requires addLiquidity operation first, otherwise order placement will fail)

• Place order:

  npx hardhat run scripts/frontend/limitorder/place.ts

• [Todo] Cancel order:

  npx hardhat run scripts/frontend/limitorder/kill.ts

• [Todo] Withdraw liquidity:

  npx hardhat run scripts/frontend/limitorder/withdraw.ts

5.3 Dynamic fee

• Adjust fee:

  npx hardhat test scripts/feehook/testfeehook.ts

UniswapV4及hook部署使用

1. 运行uniswapv4自带测试： 命令行输入npx hardhat test

2. 合约编译：npx hardhat compile 将必要的abi文件从artifacts/contracts移至scripts/frontend/abi

3. 部署uniswapv4合约以及hook合约：

   1. 运行本地区块链节点网络：npx hardhat node
   2. 配置文件,配置区块链网络、钱包以及合约地址：scripts/frontend/lib/address.ts
   3. hook合约部署脚本：npx hardhat run scripts/frontend/depoly/depoly.ts
      • 限价交易hook:contracts/LimitOrder.sol
      • 动态手续费hook:contracts/DynamicFee.sol

4. 初始化poolmanager合约： 运行初始化脚本：npx hardhat run scripts/frontend/init/init.ts

5. 合约调用：

   1. 市价交易：
      • 添加流动性：npx hardhat run scripts/frontend/marketprice/addLiquidity.ts
      • 交易：npx hardhat run scripts/frontend/marketprice/swap.ts
      • 撤销流动性：npx hardhat run scripts/frontend/marketprice/removeLiquidity.ts
   2. 限价交易：(接添加流动性操作，否则无法正常挂单)
      • 挂单：npx hardhat run scripts/frontend/limitorder/place.ts
      • [失败]撤单：npx hardhat run scripts/frontend/limitorder/kill.ts
      • [失败]提取流动性：npx hardhat run scripts/frontend/limitorder/withdraw.ts
   3. 动态手续费：
      • [存疑]调整手续费：npx hardhat test scripts/feehook/testfeehook.ts

待完成事项

• 类似挖矿的流动性激励hook合约
