path-registry

The goal of this project is to make optimal swap paths available in smart contracts without compromising on trustlessness.

The main smart contract, called PathRegistry.sol, has 2 functions:

1. A registration and a quality verification of Uniswap v2 and v3 paths.
2. Swapping tokens using the registered path. A path is selected based on input and output token addresses and the amount of input token to swap.

Setup

1. Install Foundry
2. git clone https://github.com/benesjan/path-registry.git
3. git submodule update --init
4. cp ./foundry.toml_template ./foundry.toml
5. Replace ARCHIVE_NODE_RPC_URL with actual archive node RPC endpoint (Archive node is required for tests to pass becase tests are fixed at a block.)
6. yarn
7. forge build
8. forge test

Note: Archive node is required for tests to pass because they are fixed at block 14411926. I use archivenode.io endpoint.
