[Feature Request] Attach LN Address to Spark Wallet by default

[DoktorShift]

Problem Statement

Spark wallets currently do not provide a shared or static Lightning Address that can be used across applications.

This limits interoperability, as other services cannot easily:

• forward payments
• split incoming payments
• handle automated payouts

to a Spark wallet without using wallet-specific logic.

Proposed Solution

Introduce an optional static Lightning Address for Spark wallets, specifically for use in BuhoGO.

The Lightning Address would:

• be permanently associated with the wallet
• resolve to the wallet via Spark infrastructure
• be usable by third-party applications for forwarding, splitting, or payout logic

Technical Concept

• The Lightning Address is linked to the public identifier of the Spark wallet (the Spark address).
• Incoming Lightning Address payments are resolved to the corresponding Spark wallet.
• The Lightning Address acts as a stable, human-readable entry point for external systems.

Summary

Adding an optional static Lightning Address to Spark wallets allows BuhoGO and third-party applications to interact with Spark wallets in a standardized way, without compromising user privacy. The feature strengthens the Spark ecosystem while keeping control firmly in the hands of the user.
