During September 2025, Mennat Naga developed cross-network interoperability features for the XMTP ecosystem, focusing on Lens Protocol integration. She added Lens Chain and Lens Testnet support to the xmtp-js repository, configuring HTTP transport and aligning chain IDs to enable seamless interaction with Lens networks. In libxmtp, she extended the smart contract wallet verifier to support EIP-1271 validation for Lens v3 smart accounts, mapping chain IDs to Lens RPC URLs for secure signature verification. Her work leveraged TypeScript, JavaScript, and blockchain integration skills, delivering robust, maintainable solutions that expanded XMTP’s network reach and improved security for Lens-based interactions.
