Tracking issue for MVP demo #2

[soareschen]

Context

This issue tracks the status of the progress toward MVP demo implementation by the end of February 2025.

Task List

The following items should be implemented:

Cairo Contracts

Full implementation of Cairo IBC core with mocked IBC clients for both Cosmos and Starknet.
NOTES: the mocked light clients can at best support signature-based attestation by the relayer. There is no light client security available at this point.

Comet Light Client

Preview Give feedback

1. Store chain ID in both Starknet and Comet client state #147
   cairo comet light client starknet light client +3
   
2. Authenticate based on trusted relayer's signature for the Comet client on Starknet #157
   cairo starknet light client +2
   

Starknet Light Client on Cosmos

Preview Give feedback

1. Authenticate based on trusted relayer's signature for the Starknet Wasm client on Cosmos #192
   starknet light client +1
   

Relayer

Full IBC relaying integration on public testnets with a working CLI that users can experiment with.
