Deployment Notes

If you don't need to deploy a new WETH9 contract, comment out lines 38-41 in 01deploy_univ3.ts and assign the specified contract address to the _weth9_addr variable

// Fill in existing contract address
var weth9_addr = "<address>";

// const weth9 = await deploy_WETH9(deployer);
// console.log("deployed weth9 addr: ", weth9.address);
// await delay(1500);
// weth9_addr = weth9.address;

Deploy New Liquidity Pool

Modify Parameters

Modify the address variables in 02_deploy_pool.ts

// Use the Uniswap Factory address deployed above
const univ3_factory_addr = "<uniswap factory address>";

// Order of A and B addresses doesn't matter
const tokenA_addr = "<tokenA address>";
const tokenB_addr = "<tokenB address>";

// fee (500 || 3000 || 10000) only these three values are allowed by default. More fee tiers can be added later through contract interface or by modifying source code
const fee = 500; // 0.05%

Deployment

Execute the following command in the console

npx hardhat run ./scripts/02_deploy_pool.ts  --network <network name>

The console will return the deployment transaction hash
