Mapping the Mobile Wallet Attack Surface

This talk demystifies how native mobile wallets store and handle sensitive key material on-device. Using Fedi’s in-app browser as a sample / case study, we’ll walk through how WebLN payments and NIP-07 Nostr signing are used to create a convenient UX and what security assumptions and attack surfaces come with that design.

P2P Transmission Methods

Copy-pasting is easy enough... Animated QR codes are cool too! What else can we do? In this workshop we'll explore different ways of transmitting ecash from one device to another, particularly mobile devices in low-connectivity environments. - Text-based transmission (copy-paste & send) - Visual transmission (animated QR codes) - Audio transmission (wtf? is this even possible?)
