Case Studies

AllScale powers cross-border stablecoin transactions with Turnkey

Challenge

AllScale, a stablecoin neobank, was building a platform for freelancers, creators, and small businesses to send and receive global payments. They needed to abstract complexities like private keys and gas fees so users could issue invoices and receive stablecoin funds with the simplicity of a traditional fintech product.

Solution

AllScale used Turnkey's Embedded Business Wallets to implement multiple authentication flows, making non-custodial wallet creation as simple as logging into a fintech app. With Turnkey’s session-based signing and policy engine, users can execute onchain actions without signing fatigue, while maintaining defined transaction limits and security controls.

Independently Verifiable

Turnkey’s code is regulator-ready and can be independently verified in real time, giving fintechs cryptographic proof that every stablecoin wallet and transaction runs exactly as intended.
