Fiber RGB++ Swap

Rust + CKB SDK prototype for an atomic swap / channel boundary dApp.

Architecture

• backend/ — Actix Web API server with CKB SDK integration points.
• frontend/ — Yew web UI that talks to the backend.

Requirements

• Rust toolchain (stable)
• trunk for Yew frontend builds
• A local or remote CKB node RPC endpoint for the backend

Run locally

1. Start the backend:

cd "c:\Users\MRNOBODY\Documents\Fiber RGB++ Swap\backend"
cargo run

2. Start the frontend:

cd "c:\Users\MRNOBODY\Documents\Fiber RGB++ Swap\frontend"
trunk serve --open

3. Open the UI in the browser and use the swap form.

Notes

This prototype now includes:

• POST /api/swap/initiate for swap creation with mock transaction hashes
• GET /api/swap/{swap_id} for status polling and phase progression
• GET /api/swap to list persisted swaps from the backend
• GET /api/swap/{swap_id}/raw to fetch raw transaction JSON for a specific swap
• frontend status refresh, swap detail display, and swap history table
• raw transaction JSON for funding and leap transactions included in API responses
• simulated funding/leap workflow state and verification command output

Next recommended improvements

1. Implement real CKB transaction construction for channel funding and settlement.
2. Add RGB++ leap integration using actual RGB++ validators and on-chain anchor logic.
3. Add transaction validation and error handling for timeout/failure paths.
4. Extend the UI with swap history, on-chain status indicators, and transaction hash links.
