Only Bitcoin por Sabad

Only Bitcoin is a minimal, import-only Bitcoin wallet built for one thing: paying fast by scanning a QR code, right from your browser.

IMPORT, NEVER GENERATE
Only Bitcoin never creates a new seed phrase or private key for you. You import a wallet you already control — either a BIP39 mnemonic or a raw WIF private key — and the extension derives your native SegWit (bc1...) address using the standard BIP84 path.

YOUR KEYS STAY ON YOUR DEVICE
Your mnemonic or private key is encrypted locally with a password you choose (AES-256-GCM, PBKDF2 key derivation) before it ever touches storage. Nothing is uploaded to any server. Only Bitcoin has no accounts, no cloud backup, and no analytics.

SCAN. CONFIRM. DONE.
Click the extension icon, then "Scan & Pay." Point your camera at any standard BIP21 Bitcoin payment QR code, review the amount and destination address, and confirm. The transaction is signed locally and broadcast straight to the Bitcoin network.

WHAT IT TALKS TO
Only Bitcoin fetches your balance, current fee estimates, and broadcasts transactions through mempool.space's public API — the same Esplora-compatible service used by many Bitcoin tools. No other server, no tracking pixel, no third-party SDK.

WHAT IT DOESN'T DO
- Does not generate or "create" wallets — import only.
- Does not support altcoins — Bitcoin only.
- Does not require an account, email, or phone number.
- Does not show ads.

Only Bitcoin is intentionally small in scope: one focused tool to hold an imported Bitcoin wallet and pay QR codes quickly.
