Private keys stay local
The wallet derives addresses and signing keys for UTXO coins, Quai, Qubic, Kaspa, CKB, Epic, and Zano locally. Mnemonics and private keys are not sent to the Altbase public API.

Privacy Summary
Private operations stay on the device.
Signed transactions are broadcast
For normal sends, the wallet builds and signs locally. The API receives only a signed raw transaction or a serialized signed transaction envelope for broadcast.
Addresses are queried
Balance, UTXO, history, and snapshot endpoints receive public wallet addresses. Those addresses are public blockchain data, but API access can associate requests with network metadata such as IP address.
Privacy coins use local native wallet code. When encrypted privacy cache is enabled, the server stores an encrypted blob only. Encryption keys are derived locally from the mnemonic; the server does not receive plaintext wallet cache.
