Rust implementation of the Inter-Blockchain Communication (IBC) protocol that

hosts all the data structures and on-chain logic implementations of various IBC

core, clients and applications. This repository organized as a collection of

sub-crates that can be used independently or together.

## Project Structure

| 
Crate | Description                                                                                          |

| ------------------------------------ | ---------------------------------------------------------------------------------------------------- |

| [ibc](ibc)                           | Re-exports all the data structures and on-chain logic of various IBC core, clients and applications. |

| [ibc-data-types](ibc-data-types)     | Re-exports all the IBC data types that are shared across different IBC implementations.              |

| [ibc-core](ibc-core)                 | Contains data structures and implementations of all the IBC core specifications.                     |

| [ibc-clients](ibc-clients)           | Contains data structures and implementations of various IBC light clients.                           |

| [ibc-apps](ibc-apps)                 | Contains data structures and implementations of various IBC applications.                            |

| [ibc-testkit](ibc-testkit)           | Provides testing toolkit to aid `ibc-rs` and host chains in writing integration tests.               |

| [ibc-query](ibc-query)               | Contains utility traits and implementations for querying states of an integrated IBC module.         |

| [ibc-derive](ibc-derive)             | Derive macros for `ClientState` and `ConsensusState` traits, reducing boilerplate.                   |

## Contributing

IBC is specified in English in the [`cosmos/ibc` repo][ibc]. Any protocol

changes or clarifications should be contributed there.

If you're interested in contributing, please refer to the

[CONTRIBUTING](./CONTRIBUTING.md) guidelines. We welcome and appreciate

community contributions!

## Community calls

The IBC-rs community calls are now part of the IBC Core community calls. During

these calls, we update the community on our current direction and gather

feedback on what to work on next. The community calls are also a platform for

you to update everyone else on what you're working on and find opportunities to

collaborate.

Please join the [Google group](https://groups.google.com/g/ibc-community) to

receive a calendar invitation to the monthly meetings.

## `ibc-rs` in the wild

The [IBC Protocol][ibc-protocol] is integrated in numerous networks and

projects. The `ibc-rs` implementation, in particular, is used for IBC

integration, testing, or development for some of the most technically compelling

use cases.
