Breez x Turnkey: Instant Bitcoin for Embedded WalletsBreez x Turnkey: Instant Bitcoin for Embedded Wallets

Bringing bitcoin to millions means meeting people where they are. For users, that's money that moves like the apps they already know. For developers, it's bitcoin that fits the product they've already built. Our latest update is for the latter.

Many mainstream apps run everything from the backend, with one service handling millions of users. As a result, adding bitcoin for these teams generally means holding keys on their servers, and holding keys makes you a custodian: licenses, liability, and a honeypot that never sleeps. The alternative is creating a separate experience or rebuilding the product around a device-based wallet, sacrificing the architecture that helped them scale to millions of users in the first place.

They shouldn't have to choose, and now they don't have to.

Bitcoin Tools Built for MillionsBitcoin Tools Built for Millions

Breez has partnered with Turnkey to bring instant, non-custodial bitcoin to embedded wallets. Turnkey’s enterprise-grade embedded wallet infrastructure is trusted by some of the most popular apps in the world, and the idea is simple: every user gets a wallet whose keys are created and stored inside Turnkey's secure enclaves, where nothing can reach them. Not your server. Not Breez. Not Turnkey. Your backend holds a simple credential, and you decide exactly what it's allowed to do.

Turnkey already supports Spark natively, and the Breez SDK is built on Spark. Pair that with Breez's server mode and a single backend can run multi-user wallets for millions of users, all server-side managed. Instant, non-custodial bitcoin for every user, with no keys ever stored on your servers.

How It WorksHow It Works

For builders, the model is simple: only the user can move their money. Approval comes from a credential only they hold, like a passkey registered with Turnkey when they sign up. Your server prepares the transaction and shows exactly what will move: the amount, the fee, the destination. The user approves, and the transaction completes. Your server can never spend without them.

For users, nothing changes. Same app, same flow. There's no seed phrase to write down and no new habit to learn. The difference is underneath: the money is actually in their control.

With this release, the Breez SDK now delivers the same world-class user experience at enterprise scale. It can let a million users send and receive bitcoin instantly without holding a single key. Exchanges can automate payouts under rules their security team wrote. Fintechs can provide a non-custodial bitcoin service with the same level of UX their users are used to.

And the infrastructure underneath was built for it: Turnkey signs instantly, is SOC 2 audited, and secures some of the world's most popular apps.

The Breez SDK exists to put bitcoin in every app, and to make value move like information, instantly, globally, to anyone. Piece by piece, the barriers keep falling. Passkey Login replaced the seed phrase. Stable Balance took away the volatility. Send USDT/USDC connected bitcoin to the networks where dollars move. Turnkey partnership gives the world's biggest products the simplest way to securely offer instant bitcoin and stablecoins to millions of users without taking custody of a single satoshi.

Instant, non-custodial bitcoin at enterprise scale is now, quite literally, turnkey. (Sorry, we had to.)
