April 2026 Crossmint SDK monthly summary: Implemented security enhancements with Wallet SDK Signer Pre-Authentication and delivered a major React Native/Expo packaging compatibility fix. These changes reduce integration friction for mobile apps and strengthen security posture. Key outcomes include: 1) Wallet SDK Signer Pre-Authentication added to ensure signer is authenticated before approval; 2) React Native and Expo packaging compatibility fixed by bundling @hpke/core and @hpke/common into the package output, removing metro.config.js workarounds (WAL-9601); 3) Dependency packaging cleanup with lockfile synchronization (pnpm-lock.yaml) after moving @hpke/core to devDependencies. Overall impact: smoother onboarding for mobile apps, lower maintenance cost, and stronger security during approvals.
