This repository contains the Balancer Protocol V2 core smart contracts, including the Vault and standard Pools, along with their tests, configuration, and deployment information.
For a high-level introduction to Balancer V2, see Introducing Balancer V2: Generalized AMMs.
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 Newly developed packages may not be published yet.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.
v2-deployments: addresses and ABIs of 7274 all Balancer V2 deployed contracts, for mainnet and various test networks.v2-vault: theVaultcontract and all core interfaces, includingIVaultand the Pool interfaces:IBasePool,IGeneralPoolandIMinimalSwapInfoPool.v2-pool-weighted: theWeightedPoolandWeightedPool2Tokenscontracts, 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.
Multiple independent reviews and audits were performed by Certora, OpenZeppelin and Trail of Bits. The latest reports from these engagements are located in the audits directory.
