Bay Wallet

ldk wallet & nostr client for the plebs of tampa, by tampa plebs.

Description

Bay Wallet is a project spawned from the Tampa BitDevs meetup. The goal of the project is to inspire new Bitcoin developers to work on a Bitcoin project in a collaborative environment with experienced Bitcoin developers.

Bay Wallet is built with LDK, a Lightning implementation library. LDK allows developers to create full node implementations wihtout having to use a monolithic node implementation such as LND, Core Lightning, or Eclair. This bodes well for mobile because we can run a full node on the device.

Included with Bay Wallet is a nostr client. Having a nostr client included with a Lightning wallet creates a seamless UX for zaps, community engagement, as well as app support.
