Uniswap V3

Fork Changes

I forked this repo as part of my investigation and development of a MEV Bot. The purpose being the development of a uniswap v3 simulator. Whilst developing this, I found my self refering to the uniswap v3-core tests a lot! So, to help this process, I added the ability to debug any test file independently in VS Code.

This repository contains the core smart contracts for the Uniswap V3 Protocol. For higher level contracts, see the uniswap-v3-periphery repository.

Bug bounty

This repository is subject to the Uniswap V3 bug bounty program, per the terms defined here.

Local deployment

In order to deploy this code to a local testnet, you should install the npm package @uniswap/v3-core and import the factory bytecode located at @uniswap/v3-core/artifacts/contracts/UniswapV3Factory.sol/UniswapV3Factory.json. For example:

import {
  abi as FACTORY_ABI,
  bytecode as FACTORY_BYTECODE,
} from '@uniswap/v3-core/artifacts/contracts/UniswapV3Factory.sol/UniswapV3Factory.json'

// deploy the bytecode

This will ensure that you are testing against the same bytecode that is deployed to mainnet and public testnets, and all Uniswap code will correctly interoperate with your local deployment.

Using solidity interfaces

The Uniswap v3 interfaces are available for import into solidity smart contracts via the npm artifact @uniswap/v3-core, e.g.:

import '@uniswap/v3-core/contracts/interfaces/IUniswapV3Pool.sol';

contract MyContract {
  IUniswapV3Pool pool;

  function doSomethingWithPool() {
    // pool.swap(...);
  }
}
