LaWallet: a NOSTR-Backed Lightning Wallet by Mariano Perez Rodriguez. Watch now: "How can Lightning reach the whole world? How can non-tech-savvy users be on-boarded? How can familiar payment UXs be leveraged? How can NOSTR help us be shamelessly transparent?" These were the questions we tried to answer with LaWallet: an Open Source, transparent, custodial, Lightning wallet, with built-in BoltCard support. Join us as we visit the inception, design rationale, protocols, and future extensions of this modular machine. This presentation was recorded in Buenos Aires, in February 2024 during bitcoin++ payment edition. #btcplusplus #devconf #bitcoineducation #bitcoinconf #bitcoindev #bitcoinconference #cypherpunks

Building a Custodial Lightning Wallet the Right Way by gudnuf. Watch now: Traditional Lightning wallets offer a stark choice: complex and non-custodial or privacy-compromising and custodial. Cashu bridges this gap, enabling developers to build user-friendly Lightning-enabled apps without the usual complexities. In this hands-on workshop, with the help of cashu-ts and Replit, participants will implement sending and receiving Lightning payments while exploring privacy features, offline capabilities, multi-currency support, and user-selectable custodians.

Simple Layer Twos by Christian Lewe. Watch now Christian Lewe of Blockstream Research (clewe) presents on: Simplicity is a proposed overhaul of the scripting language of Bitcoin. It fundamentally changes what can be done on layer one, but it does not stop there. Given what was possible with the existing scripts so far, imagine the explosion of ideas that Simplicity would enable. In this talk, we explore some of those applications, including Validity rollups and Fedimint accounts.
