This repository contains routing logic for the Uniswap 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.
npm run test
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_{CHAIN} = '<JSON_RPC_PROVIDER>'
For example, specifying a provider for Optimism :
JSON_RPC_PROVIDER_OPTIMISM = '<JSON_RPC_PROVIDER>'
Then from the root directory you can execute the CLI.
Some examples to use for manual CLI testing.
