Pegasys Smart Order Router
This repository contains routing logic for the Pegasys 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.
Testing
Unit Tests
First make sure you have run npm install
and npm run build
.
npm run test

Adding a new Chain
The main components to complete are:
- Deploy contracts on chain, add the pools to subgraph
- Populate v3 providers in
src/providers/v3/subgraph-provider
andsrc/providers/v3/static-subgraph-provider
- Populate chainId and addresses in
src/util/chains.ts
andsrc/util/addresses.ts
- Populate token providers in
src/providers/caching-token-provider
andsrc/providers/token-provider.ts
- Populate gas constants in
src/routers/alpha-router/gas-models/*
- Populate bases in
src/routers/legacy-router/bases.ts
- Populate
test/integ/routers/alpha-router/alpha-router.integration.test.ts
andsrc/providers/v2/static-subgraph-provider.ts
- Populate
src/routers/alpha-router/*
- Add a log to
/CHANGELOG.md
- Run
npm run integ-test
