Breeze The two companies announced that they have partnered with Turnkey to allow developers to add uncustodial bitcoins to applications that run wallets from their own servers.
The partnership addresses a structural problem. Many major applications run from the backend, with a single service handling millions of users. Adding Bitcoin into this design means keeping user keys on the company’s servers.
Holding the keys makes the company a custodian, a status that carries licensing requirements, legal liability, and the security burden of a large store of user funds. The alternative was to create a separate device-based wallet, a change that breaks the architecture these apps use to access scale.
Under the new model, each user receives a wallet whose keys are generated and stored inside Turnkey’s secure enclaves. According to the companies, those keys Stay out of reach From the app servers, Breez, and Turnkey. The company’s backend holds credentials that specify the actions it can take, while the authority to transfer funds rests with the user.
In other words, this partnership positions some of the world’s largest consumer apps to add uncustodial Bitcoin without rebuilding their backend architecture or holding users’ funds.
Turnkey supports Spark, the network on which the Breez SDK is built. Combined with Breez’s server mode, a single backend can manage wallets for millions of users without storing keys.
Registered passkeys enable Bitcoin self-custodial applications
The approval flow works as follows. The user holds credentials, such as a passkey, registered with Turnkey upon registration. The server prepares the transaction and displays the amount, fees, and destination.
The user agrees to the transaction, and it is completed. The server cannot spend money without that approval. For the user, the current flow of the application does not change, and there is no initial statement to record.
Turnkey provides an integrated wallet infrastructure used by a range of consumer applications and is subject to SOC 2 review bitcoin magazine, Breeze positioned the issue as a way for exchanges, fintechs and neobanks to offer bitcoin and stablecoin services to large user bases without siphoning off funds.
Exchanges can automate payments under rules set by their security teams, and fintech companies can add a non-custodial Bitcoin service within their existing interface.
The partnership extends to a series of Breez SDK features aimed at reducing barriers to Bitcoin integration. Passkey login replaced the seed phrase, stable balance addressed price fluctuations, and a separate feature added support for sending USDT and USDC stablecoins. The companies say the built-in tools allow products running in the background to offer bitcoin and stablecoins to users while ownership of the assets remains with those users.
