A self-custodial bitcoin wallet on Ark, in a single HTML file.

Use it: download index.html (or the repo ZIP) and open it in a modern browser. That's the whole install.

• Runs entirely in your browser — keys are generated locally and never leave it
• Bitcoin mainnet by default, signet toggle in the header
• Send and receive over Ark, Lightning, and on-chain; unified payment QR
• Optional password encrypts your recovery phrase at rest
• Encrypted wallet backup: one click downloads a backup file encrypted with a key derived from your recovery phrase (useless without the words). On Chrome/Brave/Edge, pick a file once and the wallet silently keeps it current. Restore = seed words + backup file.
• Unilateral exit: reclaim your funds on-chain with no cooperation from the Ark server (Settings → Unilateral exit). The wallet progresses the exit automatically in the background and lets you claim matured funds to any bitcoin address.
• Built on @secondts/bark, Second's official WASM SDK

⚠️ Beta software handling real bitcoin — keep amounts small. While Bark is in beta, the 12 words alone recover unspent incoming Ark payments only — funds from Lightning receives, boards, and change need the backup file too. Keep both: write down the words, keep the backup file current (the wallet shows a "backup needed" badge when it's stale).
