This package contains the addresses and ABIs of all Balancer V2 deployed contracts, for Ethereum and Polygon mainnet, as well as various test networks. Each deployment consists of a deployment script (called 'task'), inputs (script configuration, such as dependencies), outputs (typically contract addresses), and ABIs of related contracts. All tasks are found in the tasks directory, where each subdirectory represents an individual deployment.
Note that some protocol contracts are created dynamically: for example, WeightedPool contracts are deployed by the canonical WeightedPoolFactory. While the ABIs of these contracts are stored in the abi directory of each deployment, their addresses are not. Those can be retrieved by querying the on-chain state or processing emitted events.
