@balancer-labs/v2-pool-utils
Advanced tools
This package contains Solidity utilities for developing Balancer V2 Pools, implementing common patterns such as token decimal scaling, caller checks on hooks, etc.
The most useful contracts are BaseGeneralPool and BaseMinimalSwapInfoPool, used as base contracts for Pools with the General and MinimalSwapInfo/TwoTokens specializations respectively.
The recommended pattern is to create new Pools from factory contracts, as that lets other systems reason about Pool logic by checking whether a Pool was deployed from a given factory. BasePoolFactory can be used for this purpose.
$ npm install @balancer-labs/v2-pool-utils
Contracts in this package are meant to be used via inheritance to develop new Pools. The BaseGeneralPool and BaseMinimalSwapInfoPool contracts are abstract, meaning some virtual functions (such as _onJoinPool or _onSwapGivenIn) are not defined: derived contracts must override them and provide an implementation.
See v2-pool-weighted for the implementation of Pools with a Constant Weighted Product invariant using these base contracts.
