Ownbit — Self-Custody MultiSig & Cold Wallet for professionals, families & teams
Note:
Ownbit 5.0 (io.ownbit.app) is the next generation of our existing app Ownbit
(com.bitbill.www), published by the same developer account. It is a full rebuild,
so it ships under a new package name. Once Ownbit 5.0 is approved and our users have migrated (they restore their wallets with their recovery phrase), we will unpublish the old Ownbit app.
Take full control of your crypto with Ownbit, a self-custody mobile wallet that pairs air-gapped cold storage with true on-chain multi-signature. Your private keys are generated and encrypted on your own device — never uploaded to a server. Store Bitcoin (BTC), Ethereum (ETH), Tron (TRX), Solana (SOL) and 500+ coins with confidence.
Trusted across the crypto community and operating since 2017 with zero security incidents.
Key Features
• Air-gapped cold wallet — Turn a spare phone into an offline signer. Track balances on an online Watch Wallet and sign transactions by QR code, so your keys never touch the internet. No extra hardware needed.
• True on-chain MultiSig — Real M-of-N multi-signature enforced on-chain, from a personal 2-of-3 to weighted team approvals with roles, spending policies, and thresholds.
• Self-custody by design — Your keys, your crypto. Recover anytime with your standard BIP39 recovery phrase in Ownbit or any compatible wallet. No third-party custody, no counterparty risk.
• Broad multi-chain support — BTC, ETH, TRX, SOL, BNB and 500+ coins and tokens, including ERC-20, BEP-20, TRC-20 and SPL.
• Built for teams & treasuries — Structured approvals and clear signer roles for families securing a legacy and teams managing shared funds.
