About Bitcoin
What is Bitcoin (BTC)?
Bitcoin, launched in 2009, is the first decentralized cryptocurrency and remains the most widely held. It runs on a proof-of-work blockchain with a supply capped at 21 million coins and a UTXO accounting model, which makes it a natural fit for on-chain multi-signature scripts. Because it follows the BIP32/39/44 standards, a Bitcoin wallet created anywhere stays portable and recoverable. In Ownbit you can hold BTC as a standard wallet, an air-gapped cold wallet, or an on-chain MultiSig where several independent keys must approve every spend.

What you can do with it
Bitcoin in Ownbit
Self-custody by design
Your BTC mnemonic and keys are generated and encrypted on your own device — never uploaded for remote custody.
Cold-wallet workflow
Track BTC on a Watch Wallet and sign offline on an air-gapped phone; transactions move as QR codes.
On-chain MultiSig
an on-chain P2SH/P2WSH multisig script requires 2-of-3 or weighted approvals before any BTC moves.
How it works
How Bitcoin works in Ownbit
On Bitcoin, an Ownbit MultiSig address is a real on-chain P2SH/P2WSH script that needs M-of-N signatures to spend. Every participant holds an independent key, so no single person — and not Ownbit — can move funds alone. Add a Watch Wallet for tracking and keep signing keys on an air-gapped phone.
Recovery and compatibility
Bitcoin recovery & compatibility
For standard Bitcoin wallets, recovery completes with your mnemonic or private key in any compatible wallet. For MultiSig, each participant keeps an independent key and can recover from the wallet's on-chain configuration without depending on Ownbit's servers.
FAQ
Bitcoin wallet — frequently asked questions
Does Ownbit support Bitcoin MultiSig?
Yes. Ownbit supports on-chain M-of-N MultiSig for Bitcoin — an on-chain P2SH/P2WSH multisig script. You can set anything from a 2-of-2 personal wallet to weighted enterprise approvals, and the threshold is enforced on-chain rather than by a server.
Which Bitcoin assets can I hold?
Ownbit manages BTC on Bitcoin.
Is my Bitcoin self-custodial in Ownbit?
Yes. Your BTC mnemonic and private keys are generated and stored encrypted on your own device. Ownbit never holds them and cannot move, freeze, or access your funds.
Can I use Bitcoin as a cold wallet?
Yes. Pair a Watch Wallet on an online phone with an offline signing phone; unsigned and signed transactions move between them as QR codes, so your keys never touch the internet.
How do I recover my Bitcoin if I lose my phone?
Restore your BIP39 mnemonic in Ownbit or a compatible wallet. For MultiSig, each participant recovers with their own key plus the wallet's public configuration — no Ownbit server required.
