eCash (Cashu) is now live on both Mobile + Web We’re rolling out eCash support powered by Cashu across our apps, giving you fast, Bitcoin-backed payments with stronger privacy and a smoother experience for tipping/zapping, sending, and receiving. What is eCash (Cashu)? Cashu is a Chaumian eCash system built for Bitcoin. It uses blind signatures so payments are not linkable between minting and spending, which is where the privacy benefit comes from. In practice, you hold tokens in your wallet and can send them like digital cash. Cashu is typically issued by mints (services that mint and redeem tokens) and is often used with Lightning for deposits and withdrawals. On Nostr, NIP-60 defines how Cashu wallet data can be stored on relays so your wallet can follow you across apps. Nutzaps (NIP-61) are a Cashu-based way to zap where the token itself can serve as the receipt.

Quick note on mints Cashu wallets depend on the mint(s) you choose. We recommend starting small, using mints you trust, and treating eCash like spending cash for everyday use (not for long-term cold storage). Update now Update to Web v5.6.0 and Mobile v2.0.1 to start using eCash today. If you’ve got feedback or mint suggestions, tell us — this is a big step toward smoother, more native value flow inside the app.
