# Cashu over Nostr

There are two Cashu wallets with nostr capabilities right now: Nutshell (CLI, for pros) and Nutstash (beginner-friendly web wallet).

## How does it work?

In Cashu, you exchange ecash tokens (represented as a long random-looking string) denominated in Satoshis that you can redeem on Lightning with the help of a mint (the custodian).

You can send these tokens directly (and privately!) to another user's nostr pubkey (or nip05 like mine: calle@cashu.me). The tokens then show up in the receivers nostr DMs. When the receiver uses one of the above wallets, the wallets automatically scan your DM inbox for incoming tokens. When a token is received, it is automatically redeemed into your wallet.

That's it! Encrypted DMs on an uncensorable social network paired with an untraceable privacy layer for custodial Bitcoin wallets. It's a perfect match 💜
