About Cardano
What is Cardano (ADA)?
Cardano is a proof-of-stake layer-1 developed through peer-reviewed research and a formal, phased roadmap. It uses an extended UTXO model and the ADA token for fees and staking. Ownbit holds Cardano in self-custody with air-gapped cold-wallet signing, keeping keys generated and stored on your own device and recoverable from your BIP39 phrase.

What you can do with it
Cardano in Ownbit
Self-custody by design
Your ADA mnemonic and keys are generated and encrypted on your own device — never uploaded for remote custody.
Cold-wallet workflow
Track ADA on a Watch Wallet and sign offline on an air-gapped phone; transactions move as QR codes.
Standards-based recovery
Recover ADA with your BIP39 phrase in Ownbit or any compatible wallet — BIP32 · BIP39.
How it works
How Cardano works in Ownbit
Cardano in Ownbit is a single-key self-custody wallet: your BIP39 mnemonic and keys stay encrypted on your device. Run a Watch Wallet on an online phone and keep the signing key on an offline phone for air-gapped, QR-based cold storage.
Recovery and compatibility
Cardano recovery & compatibility
Recovery completes with your BIP39 mnemonic or private key in Ownbit or any compatible wallet — control of your ADA always stays with your keys, not a server.
FAQ
Cardano wallet — frequently asked questions
Is my Cardano self-custodial in Ownbit?
Yes. Your ADA 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.
Which Cardano assets can I hold?
Ownbit manages ADA.
Can I use Cardano 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 Cardano if I lose my phone?
Restore your BIP39 mnemonic (BIP32 · BIP39) in Ownbit or any compatible wallet to regain access to your ADA.
Does Ownbit support Cardano MultiSig?
Cardano is supported as a single-key self-custody and cold wallet. On-chain MultiSig is available for chains like Bitcoin, Ethereum, and TRON; for Cardano, Ownbit focuses on self-custody with air-gapped cold-signing.
