Javi Ribo contributed to the MetaMask/metamask-sdk repository by building and refining a robust multichain SDK, focusing on cross-platform wallet integration, onboarding flows, and developer tooling. He implemented features such as Mobile Wallet Protocol integration, IndexedDB-based persistence, and modular UI components for installation and authentication. Using TypeScript, JavaScript, and React, Javi consolidated session management, transport handling, and error reporting, while standardizing APIs and improving code quality through refactoring and linting. His work addressed edge cases in onboarding and state transitions, enhanced documentation, and streamlined release processes, resulting in a more reliable, maintainable, and developer-friendly SDK foundation.
In October 2025, the metamask-sdk team delivered a comprehensive Multichain SDK refresh focused on reliability, onboarding UX, and developer productivity. The work consolidated initialization, transport handling, and session management with improved modal lifecycle and onboarding flows, addressing critical edge cases and race conditions. Documentation was refreshed to reflect installation, development commands, and build steps across the SDK-multichain packages and related playgrounds.

September 2025 — MetaMask metamask-sdk: Delivered key features to strengthen cross-wallet integration and data persistence while tightening release reliability. Implemented Mobile Wallet Protocol (MWP) integration to enable seamless, session-managed connections between the SDK and mobile wallets, with UI for installation/OTP and platform-specific adjustments; adopted IndexedDB for web storage to improve persistence, with added tests; launched a multichain developer playground in React to validate networks, wallet connections, and RPC invocations, refactoring the flow to use ConnectionRequests for QR code generation/management and improved modals, session handling, and error reporting; completed a release rollback to address the rollback issue for version 0.33.1 and updated changelogs across affected packages to maintain accuracy and transparency. These workstreams improved reliability, developer experience, and cross-wallet interoperability, enabling faster iteration and safer rollouts.

July 2025 delivery focused on establishing a robust, multi-chain MetaMask SDK foundation, tightening developer experience, and enabling cross-platform integrations. Key outcomes include a core multi-chain framework with event handling, platform detection, and error handling; new install and OTP modal UI components; a cross-platform storage layer with standardized get/set/delete semantics; comprehensive code quality improvements; and a Node.js playground to accelerate developer adoption. These changes reduce integration time for partners, improve reliability across desktop, mobile, and web, and strengthen the SDK's extensibility for future features.
