Biscuit Wallet
Biscuit Wallet
Docs › Your wallet
Wallet › Information shows where the open wallet is stored, and Settings › Storage › Paths shows every folder Biscuit uses, with buttons to open them.
| Wallets | Settings and app data | |
|---|---|---|
| Windows | Documents\Biscuit\wallets | AppData\Roaming\Biscuit |
| macOS | ~/Biscuit/wallets | ~/Library/Application Support/Biscuit |
| Linux | ~/Biscuit/wallets | ~/.config/biscuit |
In portable mode and on Tails, both live in a biscuit_data folder next to Biscuit instead. To use another wallet folder, choose it in Settings › Storage › Paths; existing wallets aren’t moved for you.
| File | What it holds |
|---|---|
name.keys | The Monero keys and wallet settings. Lose it without your seed, and the coins are gone. |
name | The Monero cache: transactions, labels, contacts, notes, transaction keys, your Polyseed. Biscuit rebuilds most of it by syncing, but not labels, notes or transaction keys. |
name.btcltc | Your Bitcoin and Litecoin wallets: seeds, addresses, labels, contacts, swap history. |
All three are encrypted with your password. The Monero files use Monero’s own scheme (ChaCha20, with a key derived from the password by CryptoNight). The Bitcoin and Litecoin file uses XChaCha20-Poly1305, with a key derived by Argon2id, which is deliberately slow and memory-hungry to make guessing passwords expensive.
If the Monero cache can’t be read, Biscuit renames it name.old_cache and builds a new one.
settings.json | Your settings |
|---|---|
datafeed-cache.json | The last prices and Journal, so they show at once on the next launch |
tor/ | The Tor that Biscuit starts, and its data |
atomicswaps/ | The state of your atomic swaps |
libwallet.log | Monero’s log, empty unless you turn on Settings › Storage › Logging |
Never delete atomicswaps/ while a swap is running: it holds what Biscuit needs to finish it or get your Bitcoin back.
The Monero files are standard: a wallet from Feather or Monero’s own wallets opens in Biscuit, and the other way round. Keep both programs up to date before moving a wallet between them.
