- Libraries & wallet updates
- Mint management tools
- Decentralized private AI access
- Bitchat
- Cashu Design
https://blog.cashu.space/cashu-highlights-q3-25/
Read: A team at StarkWare proposed a new NUT specification for integrating zero-knowledge programs in Cashu.
This would allow arbitrary ecash spending conditions without revealing the script to the mint, maintaining excellent user privacy. More in our latest blog post.

With Cashu Brr, you can print physical notes with QR codes holding redeemable Cashu tokens. Hand them over like cash and redeem them anytime.
Perfect for onboarding, just like here at a meetup in Cuba ⚡🥜
Coco RC20 is released!
The newest version adds `sweep` to the wallet API. This allows you to sweep funds from a bip 39 seed into your coco wallet.
https://github.com/cashubtc/coco/commit/119459ff9365a22de48503b607dc40d52711eb6b
Coco is a TypeScript library based on cashu-ts, making it easy to build a wallet without diving deep into the Cashu protocol nostr:nevent1qvzqqqqqqypzph0s8t9gtt0q88n8gt2mau7lx5klrxws6v0z9wv93eld4pwt8wa7qy88wumn8ghj7mn0wvhxcmmv9uq3uamnwvaz7tmwdaehgu3dwp6kytnhv4kxcmmjv3jhytnwv46z7qpqpa0g8kmfgjdvamvh322nfylr6wun48w8cuud5spw4nyn8fjtclqsjspy0y
Cashu is bringing tap to pay to Bitcoin.
Ecash travels from one device to another without Internet. Instant, privacy-preserving, peer to peer, built on open protocols.
Join the Bitcoin UX revolution. https://blossom.primal.net/57bcc9b8643e26878a51616875e54732cc7a29c02c66eecf8455d283a3b87750.mp4
Cashu will bring tap-to-pay to Bitcoin. 
The perfect Bitcoin wallet progression, all in one app:
1️⃣ Start with Cashu for small amounts
2️⃣ Upgrade to self-custody with Lightning
3️⃣ Secure your stack in cold storage
peer to peer ecash transactions in a nutshell
1 - alice sends ecash token to carol
2 - carol sends ecash to bob the mint
3 - bob verifies and checks for double-spending
4 - bob issues a new token to carol
like physical cash, step 1 is instant and works without internet. https://blossom.primal.net/5acf53584ac8a5487246983896055066968d2316c35f22e4ff5a454954e8055f.mov
