Nutstash is a Cashu wallet for your browser.
What is Cashu? "Cashu is a free and open-source Chaumian ecash system built for Bitcoin. Cashu offers near-perfect privacy for users of custodial Bitcoin applications. Nobody needs to knows who you are, how much funds you have, and with whom you transact with." - cashu.space This app is in early development and most likely buggy. It does handle real sats though, so be sure to use only amounts that are small enough to lose.
