The canonical repository for Interchain Standards (ICS) defining the Inter-Blockchain Communication (IBC) protocol used across the Cosmos ecosystem. It hosts specifications for the core transport, authentication, and ordering layer (IBC/TAO) as well as application-layer packet semantics (IBC/APP), including the newer IBC v2 standards.
Use cases
- understand how the IBC cross-chain communication protocol works
- read the official IBC interchain standards specifications
- implement IBC protocol support in a blockchain
- learn about IBC v2 client and packet semantics
- contribute to or propose new interchain standards
- find reference implementations of IBC standards
When to choose
- you are building or integrating IBC into a Cosmos SDK chain or other blockchain
- you need the authoritative, up-to-date protocol specifications for IBC v1 or v2
- you want to follow or contribute to interchain standards development
When to avoid
- you need a runnable IBC implementation rather than specifications - use ibc-go instead
- you want a general-purpose blockchain framework rather than protocol standards
- you need end-user tooling for transferring tokens across chains
