This week we dig into the growing NIP-55 signer ecosystem as Primal Android ships eight PRs to become a full local signer alongside Amber and Aegis. Shopstr's new Zapsnags feature turns your social feed into a flash sale marketplace—one zap and you've bought it. Mostro tackles the sustainability question with an opt-in development fund that lets relay operators contribute a percentage of trading fees. On the library side, NDK fixed a duplicate write bug that was adding 3.6 seconds to app boot, cutting cache queries from 3,690ms to 22ms. We walk through NIP-02 and NIP-10—the specs that make follow lists and threaded conversations work—and close with a discussion on Tenex's RAL architecture for coordinating AI agents over Nostr.
