Security built in

Your keys. Your Bitcoin. Bitcoin & Satoshi is designed so that attackers and thieves have as little to work with as possible.

  • Your seed stays on your device. It is stored only on your iPhone – never in iCloud, never in a backup, never on our servers.

  • True randomness. Every seed is created exclusively with iOS's proven system random number generator. Faulty random values are rejected.

  • Address check before every send. The start and end of the recipient address are highlighted, and you confirm before sending. This protects against tampered or look-alike addresses.

  • Protected clipboard. The app reads the clipboard only when you tap, and copied addresses clear themselves automatically.

  • No screenshots of your seed. Seed screens are protected against screenshots and screen recordings, and hidden in the app switcher.

  • PIN lock and Face ID. After each wrong PIN the waiting time grows, making guessing practically impossible.

  • Vetted software components. All building blocks are pinned to reviewed versions. Tampered updates cannot slip in unnoticed.

  • We never ask for your seed. Bitcoin & Satoshi, our team and our support will never ask for your seed phrase – and support never contacts you via DM. Anyone who does is a scammer.

We will never ask for your recovery phrase.

Nobody from Bitcoin & Satoshi – not support, not by email, X or phone – will ever ask for your seed words. Anyone who does is trying to steal your bitcoin. Never type them into a website or share them, not even as a screenshot.

Security model

Non-custodial means control — and responsibility — sit with you.

0:00 / 0:00

What non-custodial means

With a custodian (exchange, bank), the provider holds the keys. With Bitcoin & Satoshi, they live on your device.

We cannot authorise transactions, freeze balances, or recover lost wallets. That is not a gap — it is the product.

Recovery phrase

During setup the app creates a seed phrase. Write it down offline and store it away from the phone.

Anyone who knows the phrase can restore the wallet on another device. Share it with no one. Do not photograph it into a cloud album.

If you lose both the phrase and the device, the coins are gone. There is no master key on our side.

Device and updates

Protect the phone with a system PIN, biometrics, and a current OS. Do not sideload the app from unknown sources.

Always confirm receive addresses in the app — not only from screenshots or chat messages.

Third parties (MoonPay and others)

When you buy bitcoin with fiat you use a separate, often licensed service. Their identification, limits, fees, and blocklists apply to that purchase.

Once the payout is on-chain, only Bitcoin’s rules apply — not the partner’s, and not ours.

Age and responsibility

Send and receive are not age-locked. A minor can hold keys on their own device. Losing the phrase still means the coins are gone — for a child as for an adult. There is no recovery desk.

Buy and sell with fiat open only at the age of majority where you live, and only through the partner’s own checks. We cannot undo a partner’s decision, and we cannot move coins after they arrive.
