This repository contains routing logic for the Udonswap V3 protocol.
It searches for the most efficient way to swap token A for token B, considering splitting swaps across multiple routes and gas costs.
First make sure you have run npm install and npm run build.
npm run test
Make sure the .env file is configured to connect to mainnet and other chains. See the CLI section below for more details.
npm run integ-test
Quotes can be simulated on Tenderly
Ensure you set the following environment variables:
process.env.TENDERLY_BASE_URL!,
process.env.TENDERLY_USER!,
process.env.TENDERLY_PROJECT!,
process.env.TENDERLY_ACCESS_KEY!,
The package can be run as a CLI for testing purposes.
First create a .env file in the root of the project and configure:
JSON_RPC_PROVIDER = '<JSON_RPC_PROVIDER>'
To run on chains other than mainnet set up a connection by specifying the environment variable
JSON_RPC_PROVIDER_MODE = '<JSON_RPC_PROVIDER>'
Then from the root directory you can execute the CLI.
./bin/cli quote --tokenIn 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA --tokenOut 0x4200000000000000000000000000000000000006 --amount 10 --exactIn --minSplits 1 --protocols v3 --router alpha --chainId 919
The main components to complete are:
- Deploy contracts on chain, add the pools to subgraph
- Populate v3 providers in
