Bitcoin wallet security and recovery

This wallet is non-custodial: the recovery phrase controls the Bitcoin. Transaction signing is performed in the browser rather than by an account on the hosting server.

Recovery phrase

The recovery phrase can restore the same deterministic wallet and its supported address branches. Anyone who obtains the phrase can derive the private keys and spend the associated Bitcoin, so it should be stored offline and kept private.

Persistent browser access

To keep an opened wallet available after a page refresh or browser restart, the current implementation stores the wallet recovery data in this website origin's browser storage until Close wallet is used. This improves convenience but makes browser and website security especially important.

Before using significant funds

• Verify the website address and HTTPS connection.
• Keep an offline backup of the recovery phrase.
• Test recovery and sending with a controlled amount first.
• Review the recipient address and fee before broadcasting.
