The lib directory contains git-submodules which in turn also have submodules. To update all submodules recursively, execute:

git submodule update --init --recursive

Docs

To build the docs locally, run docs-build. The output will be inside of ./result.

Run docs-serve to serve the docs locally (after building them previously). You can edit the docs in ./docs.

Running tests

To run all tests, you can use check (alias for nix flake check); it will build all packages and run all tests.

You can use tests -h to execute a specific test, which will provide more information.

Formatting

You can manually format the source using the fmt command.

MevEth - Maximizing Ethereum Value

The MevEth contract serves as a sophisticated platform for Liquid Staking Receipt (LSR) management, designed to optimize Ethereum value through efficient staking and reward distribution. This contract leverages multiple core modules to achieve its objectives, including admin control, staking management, share vault updates, ERC4626 integration, withdrawal queues and omni-chain tokens.
