Easy to integrate. The Spend SDK is designed to complement your existing user interface and installs with just a few lines of code.

The Spend SDK is available for iOS and Android and supports the following wallet structures:

Custodial and exchange wallets
Smart contract wallets
Self-custody (non-custodial) wallets

Simple to use. Flexa’s end-to-end merchant integrations provide your users the easiest checkout experience, both online and off.

Whether showing a flexcode from their mobile device or scanning a payment request on the web, the Spend SDK makes instant payments with digital assets fast and seamless. Flexa handles payment authorization and reporting so that you can focus on the more important parts of your app experience.

Fully compliant. Through an embedded verification flow, Flexa provides complete regulatory coverage and AML protections.

As an app developer, regulatory compliance is often the last thing you want to worry about.

Flexa’s robust anti–money laundering technology and policies ensure that payments made with the Spend SDK are fully compliant with local regulations in supported jurisdictions, while requiring far less intrusive data collection than traditional KYC.
