PROFILE
Robin Curbelo
Worked on the Crossmint/crossmint-sdk repository, focusing on authentication, wallet reliability, and developer experience for React Native and web platforms. Addressed a race condition in wallet initialization by deferring TEE connection until after WebView readiness, reducing runtime errors for email and phone signers. Improved authentication flows by refactoring error handling to surface specific OTP verification messages and updating state management to ensure accurate promise resolution. Enhanced onboarding for mobile developers by expanding documentation on embedded checkout for in-app credit card payments. Leveraged TypeScript, JavaScript, and React Native to deliver targeted bug fixes and documentation updates that improved SDK stability and integration clarity.

Apr 1, 2026Consolidated wallet initialization reliability in Crossmint SDK by fixing a WebView race condition in getWallet and deferring clientTEEConnection until after WebView initialization. This prevents errors when WebView is not ready for email/phone signer wallets and ensures TEE is available during wallet construction. Implemented unconditional WebView initialization before building wallet options and added a changeset to reflect the fix.

Oct 1, 2025October 2025 monthly summary for Crossmint SDK focusing on reliability and correctness of OTP verification in Non-Custodial Signer. Delivered a critical bug fix that propagates OTP verification errors accurately, refactors error handling to surface specific verification response messages, and updates the needsAuth state to ensure authentication promises resolve or reject appropriately based on verification outcomes. This work improves end-to-end authentication reliability, reduces user friction, and enhances developer experience for SDK integrators.
