 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/)).
