Symmetric V2

This repository contains the Symmetric Protocol V2 core smart contracts, including the Vault and standard Pools, along with their tests, configuration, and deployment information.

Structure

This is a Yarn 2 monorepo, with the packages meant to be published in the pkg directory. Newly developed packages may not be published yet.

Active development occurs in this repository, which means some contracts in it might not be production-ready. Proceed with caution.

Packages

• v2-deployments: addresses and ABIs of all Symmetric V2 deployed contracts, for mainnet and various test networks.
• v2-vault: the Vault contract and all core interfaces, including IVault and the Pool interfaces: IBasePool, IGeneralPool and IMinimalSwapInfoPool.
• v2-pool-weighted: the WeightedPool and WeightedPool2Tokens contracts, along with their associated factories.
• v2-pool-utils: Solidity utilities used to develop Pool contracts.
• v2-solidity-utils: miscellaneous Solidity helpers and utilities used in many different contracts.
• v2-standalone-utils: miscellaneous standalone utility contracts.

Build and Test

On the project root, run:

$ yarn # install all dependencies
$ yarn build # compile all contracts
$ yarn test # run all tests

This will run all tests in parallel. To run a single workspace's tests, run yarn test from within that workspace's directory.

You can see a sample report of a test run here.
