Self-custody explained
Self-custody is the foundational principle behind Bread. It means your private keys — the cryptographic proof that you own your bitcoin — are generated on your device, stored on your device, and never shared with Bread or anyone else.
This article explains what that means in practice, why it matters, and how it compares to the alternatives.
How it works
Keys are created locally
When you create a Bread wallet, your device generates a random set of cryptographic keys using its built-in secure enclave. These keys are the mathematical proof of ownership for your bitcoin. They never leave your phone — not during setup, not during transactions, not ever.
Your recovery phrase is your backup
The 12-word recovery phrase you write down during setup is a human-readable encoding of your private key. If you lose your phone, the recovery phrase is the only way to regenerate your keys and access your bitcoin on a new device.
Transactions are signed on-device
When you send bitcoin, swap, or make a payment, the transaction is signed by your private key on your device. Bread’s servers never see your key — they only receive the signed transaction to broadcast to the network.
Self-custody vs. custodial wallets
Most people’s first experience with crypto is through a custodial service — Coinbase, Binance, Cash App, Robinhood. In these systems, the company holds your keys and gives you an IOU.
What you gain with self-custody
- No counterparty risk — If Bread disappeared tomorrow, your bitcoin is still yours. You can restore your wallet with your recovery phrase in any compatible wallet app.
- No account freezes — No one can freeze your funds, restrict your withdrawals, or lock you out of your own money.
- No data collection — No KYC, no identity verification, no personal data stored on servers.
- Censorship resistance — Your transactions can’t be blocked or reversed by a company or government.
What you take responsibility for
- Your recovery phrase — If you lose it and lose your device, your bitcoin is gone. There is no recovery process.
- Device security — If someone gets physical access to your unlocked phone, they could access your wallet.
- Phishing awareness — No one should ever ask for your recovery phrase. Not Bread support, not a DeFi app, not anyone.
Why Bread chose self-custody
We believe the whole point of bitcoin is sovereignty — owning your money without intermediaries. A bitcoin wallet that holds your keys for you defeats the purpose.
That said, self-custody has historically been hard to use. Confusing seed phrases, clunky interfaces, and the fear of doing something wrong have kept most people on custodial platforms.
Bread is built to close that gap. Self-custody security with an experience that feels as simple as Cash App. You get full ownership without the full complexity.
Security best practices
- Write your recovery phrase on paper and store it in a safe place
- Enable biometric authentication (Face ID / Touch ID) in the app
- Keep your phone’s operating system updated
- Never share your recovery phrase with anyone, for any reason
- Be skeptical of any message, email, or website asking you to “verify” or “connect” your wallet
