Bounty Specification: Build a Nostr Wallet Connect Wallet Service Extension for LNbits#

Project Overview

This project aims to build a Nostr Wallet Connect (NWC) extension for LNbits to allow LNbits to act as a NWC Wallet Service as defined in NIP-47 https://github.com/nostr-protocol/nips/blob/master/47.md

LNbits has an example extension that can be used as a starting point on your extension development journey. Watch the extension build tutorial video here

Objective

To develop a fully functional NWC Wallet Service extension that adheres to the NIP-47 protocol specifications, enabling the following capabilities:

• Generation and handling of Nostr Wallet Connect URIs.
• Processing of payment requests including pay_invoice, make_invoice, lookup_invoice, list_transactions, get_balance, multi_pay_invoice, pay_keysend, multi_pay_keysend and get_info
• Creation and lookup of invoices.
• List and balance querying functionalities.
• Secure communication through encrypted events as per NIP04.
• Implementation of error codes
• Implementation of connection rules with control of the following: Maximum payment amount, maximum daily budget, connection expiry date (never expire should be an option) denominated in sats.

Deliverables

1. NWC Wallet Service Extension Code: Clean, commented, and secure codebase that uses the existing LNbits nostrclient.py functionality and an LNbits funding source to provide a NWC Wallet Service.
2. NWC Wallet Service Extension UI: A user interface within the extension that allows a user to connect a new app to the NWC wallet service and edit existing connections. The app connection should allow control of the following rules: Maximum payment amountMaximum daily budgetConnection expiry date (never expire should be an option)
3. Documentation: Documentation covering:
   • Setup and configuration instructions.
   • Usage examples.
4. Test Suite: A comprehensive test suite covering all key functionality

Technology Requirements

• The extension must be developed in Python, consistent with the LNbits platform.
• Use of existing LNbits libraries and adherence to its architectural style is required.
• NIP-47 specification must be adhered to.

Budget

• Total Bounty: 750,000 sats
• Payment will be made upon final delivery, after successful testing and documentation review.

Evaluation Criteria

• Adherence to the NIP-47 specifications and LNbits integration requirements.
