It feels like Cashu and Fedimint excitement peaked several hype cycles ago, but it's cool to see work like this still happening.

coco provides a complete foundation for Cashu development with a storage-agnostic core that handles proof management, mint synchronization, quote lifecycle, counter tracking, and state updates through a typed event bus. Published packages now live under the @cashu npm scope.

Maintained adapters currently cover Node via @cashu/coco-sqlite, Bun via @cashu/coco-sqlite-bun, web via @cashu/coco-indexeddb, and Expo/React Native via @cashu/coco-expo-sqlite.
