radFi Actions Flowchart

Key Components

Frontend (FE)

• User interface for sending actions and signing transactions.

RadFi Backend (BE)

• Processes requests, generates PSBTs, and handles transaction broadcasting.

Pending State Contract

• Temporary contract validating transactions before final submission.

Sequencer

• Ensures transaction validity before sending it to the Main State Contract.

Main State Contract

• Stores finalized transactions after validation.

Bitcoin Chain

• Bitcoin mainnet where transactions are permanently recorded on-chain.

Database (DB)

• Stores transaction-related data for tracking and verification.

Flow Overview

1. Fetch Pool and Ratio Data

• The FE retrieves pool and ratio data from the user.

2. User Action Request

• The user initiates an action via the FE, which sends a request to the RadFi BE.

3. Generate PSBT (Partially Signed Bitcoin Transaction)

• The BE creates a PSBT and sends it back to the FE for user signing.

4. User Signs PSBT

• The user signs the PSBT and returns it to the BE.

5. Broadcast Signed Transaction to Pending State Contract

• The BE broadcasts the signed transaction to the Pending State Contract.

6. Transaction Validation

• The Pending State Contract processes the transaction and returns a success/failure status.

7. Notify Frontend

• The BE relays the transaction success/failure result back to the FE.

8. Sequencer Processing

• If the transaction is successful, the BE sends the signed transaction to the Sequencer for final verification.

9. Broadcast Final Transaction to Main State Contract

• The Validator broadcasts the final transaction to the Main State Contract.

10. Transaction Finalization on Bitcoin Mainnet

• The Validator broadcasts the fully signed transaction to Bitcoin mainnet, completing the process.
