Implement Sovereign <> Cosmos relaying in Hermes SDK

[Farhad-Shabani]

Background

This issue outlines the high-level tasks required to achieve relaying between Sovereign and Cosmos chains within the Hermes SDK. The provided steps serve as an initial roadmap and will be updated as progress is made:

Naive relaying without recursive ZK proofs

• Will update every immediate height

Relaying with lazy waiting of recursive ZK proofs

• Wait for rollup provider to post recursive ZK proofs

Relaying with active ZK proofs generation

• Relayer would call the corresponding ZK prover to generate ZK proofs

Prerequisites

The following tasks should be completed before any efforts can be made on the relayer implementation front:

Tasks

Preview Give feedback

1. Hermes should be able to craft 08-wasm client messages #21
   relayer +1
2. Empower Hermes to retrieve essential data from Sovereign rollups #32
   4 of 6
   relayer tracking +2
