🔐 Your mnemonic is encrypted and stored locally in Chrome. Never transmitted.
Your keys never leave your browser
Your mnemonic is encrypted in Chrome's isolated extension storage. Never sent to any server.
All Bitcoin transactions (PSBTs) are signed locally using Taproot Schnorr signatures.
Chrome extensions run in an isolated process. Websites cannot access your wallet data.
You can inspect every line of code. No hidden scripts, no tracking, no analytics.
When you create your wallet, you'll receive 12 or 24 words (mnemonic).
⚠️ If you lose these words, you lose access to your funds FOREVER. There is no recovery.
