Alex Cordero from the Stellar Development Foundation presented the Wallet SDK, a new developer tool that simplifies wallet integration with anchors by reducing implementation complexity from 291 lines of code to just 10 lines, while maintaining interoperability standards.
At Meridian, Alex Cordero, Senior Director of Engineering at the Stellar Development Foundation, introduced the Wallet SDK, a comprehensive developer tool designed to simplify wallet-anchor integration. The SDK addresses the challenge of implementing complex Stellar Ecosystem Proposals (SEPs) by providing standardized, production-ready code that captures all edge cases and nuances. Currently available in Kotlin and TypeScript, the SDK supports Stellar Auth, account recovery, fee sponsorship, and interactive on/off-ramping, reducing implementation effort from 291 lines of code to 10 lines. Cordero explained how premature standard definition, backwards compatibility requirements, and communication challenges have historically made interoperability difficult. The SDK solves this by allowing developers to focus on user experience rather than standards compliance. Future roadmap includes SEP-6 support and Soroban integration, with the team actively seeking community feedback.
