Biscuit Wallet
Features
Everything Biscuit does, and where it does things differently from other wallets.
Three coins, one wallet
Monero, Bitcoin and Litecoin live in the same window, behind the same password. Send, Receive and History work for all three: pick the coin at the top, or just paste an address in Send and Biscuit recognizes the coin by itself. The status bar shows every balance at once, and a click on it shows what each wallet holds and what it’s worth in your currency.
Most wallets that hold several coins are web apps in disguise, heavy and chatty. Biscuit is a real native desktop app that opens in a second.
Swaps, two ways
- Exchange swaps between any two of XMR, BTC and LTC, through Trocador. It asks many exchanges at once, keeps only the ones that don’t ask for your ID, and ranks them by one thing: what you actually receive. You send from your wallet and get paid into your wallet. We never add a fee on top: Trocador shares part of the exchange’s own fee with us, so you pay the same as on the exchange.
- Atomic swaps from Bitcoin to Monero, directly with a market maker, using the protocol from eigenwallet. There’s no exchange in the middle and no account: either the swap completes, or your Bitcoin comes back to you. It works over Tor.
Tor, for real
- Tor is built in. Turn on Tor mode at first launch or in the settings, and Biscuit hides your IP address: its connections to Electrum servers, swap makers and our server go through Tor, and so do its connections to Monero nodes (set Always over Tor to include a wallet’s first sync). There’s nothing else to install. Exchange swaps are off in Tor mode, because our swap partner requires us to record the IP address each swap comes from (see the privacy policy).
- Tor just for prices and updates. If you leave Tor mode off, Biscuit can still fetch prices, the Journal and updates through Tor.
- Our own onion service. In Tor mode, prices, the Journal and updates come from our .onion address, so that traffic never leaves the Tor network.
- Biscuit checks that it works. If your connections don’t actually come out of Tor, the status bar tells you, instead of letting you believe you’re hidden.
- Tails and Whonix are recognized: Biscuit uses the system’s Tor, and on Tails it keeps your wallets next to the AppImage in your Persistent folder.
Monero, the Feather way
Monero in Biscuit is Feather Wallet, and we try not to get in its way: subaddresses, coin control, transaction proofs, view-only wallets, Ledger and Trezor, offline signing with QR codes on a computer that never goes online, and your own node.
Bitcoin and Litecoin, done carefully
- Light wallets over Electrum servers, the public ones or your own, on your home network or over .onion.
- Coin control: see every coin, freeze the ones that must never move, and send only the coins you choose.
- Fee bumping when a payment is slow, and paying silent payment addresses, which never appear on the blockchain.
- A new address after each payment, so people who pay you can’t see your other payments, with every old address still listed and still working. Or keep one address for good if you prefer.
- Several wallets per coin, each with its own name and seed, all under the same password.
- Signed messages to prove an address is yours, and contacts for the addresses you pay often.
Yours, and only yours
- Your keys never leave your computer. Wallet files are encrypted with your password. Biscuit never holds your coins, and nothing is sent until you confirm it.
- No account, no analytics, no crash reports. Every copy of Biscuit makes the same requests, so they say nothing about your wallet.
- Standard seeds: Polyseed for Monero, BIP39 for Bitcoin and Litecoin, so your coins open in other wallets too.
Releases you can check
Every release is built with Guix, like Bitcoin Core and Monero, so anyone can rebuild it from the source and compare. Every release is signed, and Biscuit updates itself only after checking that signature. The source of each release is published right next to it.
The little things
- A light and a dark theme, and icons drawn pixel by pixel.
- The Journal inside the app, on the Home tab: our essays, news and releases. Like prices, it shows the moment Biscuit opens, then refreshes quietly.
- Windows, macOS (Apple Silicon and Intel) and Linux, including Tails.
