Worked on foundational enhancements to the wormhole-foundation/native-token-transfers repository by initiating support for NttOwner, enabling ownership and permissions features within the Native Token Transfer system. This involved setting up the initial integration, performing interface checks, and preparing dependency updates, with ongoing work to fully implement these capabilities. Additionally, upgraded the core runtime environments in the wormhole-foundation/wormhole repository by standardizing Node.js 22 across Dockerfiles and CI pipelines. This update improved security, performance, and consistency throughout build and deployment processes. The work leveraged skills in Docker, Node.js, and TypeScript, focusing on maintainability and future readiness of the codebase.
