Security by design

Secure self-custody

Ownbit emphasizes self-custody: critical secrets stay encrypted on-device, key derivation follows industry standards, and sensitive signing can move fully offline.

Encrypted locally

Mnemonic and seed are stored with enhanced local encryption rather than uploaded for remote custody.

Standards compatible

BIP32, BIP39, and BIP44 compatibility helps keep wallet generation and recovery predictable.

Only derive when needed

Private keys are derived for signing when required, reducing unnecessary exposure in normal use.

Encrypted backup options

QR-based mnemonic backup adds a practical layer for secure migration and disaster recovery.

Cold wallet

A true offline signing flow without extra hardware.

Turn a spare phone into a dedicated signer. Keep one device permanently offline, prepare transactions on a Watch Wallet, and exchange only QR data between them.

Offline signer

Keep private material on an air-gapped device that never needs to touch the network.

Watch wallet pairing

Mirror addresses on an online device to monitor balances and prepare transfers safely.

Human-verifiable QR flow

Scan unsigned data in, sign offline, and scan the signature back to broadcast.

MultiSig

From personal protection to family and enterprise approvals.

Use 2-2 for personal risk reduction, x-3 for family coordination, and x-4+ or Enterprise MultiSig for operational treasury with clearer governance.

2-2 for personal use

Add a second device or signer so one mistake or one lost phone does not become a single point of failure.

x-3 for family use

Coordinate long-term savings, inheritance planning, or shared funds with flexible threshold signing.

x-4+ for teams

Layer roles, policies, and approval thresholds for operational wallets and treasury control.
