Rust implementation of an Inter-Blockchain Communication (IBC) relayer.

This project comprises primarily of 6 crates:

[ibc-relayer][relayer-crate-link] provides an implementation of an IBC relayer, as a library.
[ibc-relayer-cli][relayer-cli-crate-link] is a CLI (a wrapper over the ibc-relayer library),

comprising the hermes binary.

[ibc-chain-registry][ibc-chain-registry-crate-link] provides functions to fetch data from

the chain registry and automatically generate chain configuration for Hermes.

[ibc-telemetry][ibc-telemetry-crate-link] is a library for use in the Hermes CLI,

for gathering telemetry data and exposing that in a Prometheus endpoint.

[ibc-relayer-rest][ibc-telemetry-crate-link] is a library for use in the Hermes CLI,

for exposing a REST API to inspect the state of the relayer.

[ibc-test-framework][ibc-test-framework-crate-link] provides the infrastructure and framework

for writing end-to-end (E2E) tests that include the spawning of the relayer together with Cosmos full nodes.

See the table below for more details.

⚠️ The [ibc][ibc-rs-repo] and [ibc-proto][ibc-proto-rs-repo] crates have been moved to their own repositories.

The repository also includes TLA+ specifications.
