-Each Bundler is a domain-specific abstract layer of contract that implements some functions that can be bundled in a single call by EOAs to a single contract.

+Each Bundler is a domain-specific abstract layer of contract that implements some functions that can be bundled in a single call by EOAs to a single contract. They all inherit from [`CoreBundler`](./src/CoreBundler.sol) that enables bundling multiple function calls into a single `multicall(bytes[] calldata data)` call to the end bundler contract. Each chain-specific bundler is available under their chain-specific folder (e.g. [`ethereum`](./src/ethereum/)).
 
 Some chain-specific domains are also scoped to the chain-specific folder, because they are not expected to be used on any other chain (e.g. DAI and its specific `permit` function is only available on Ethereum - see [`EthereumPermitBundler`](./src/ethereum/EthereumPermitBundler.sol)).
