Keenn worked on enhancing the WCN client within the reown-com/blockchain-api repository, focusing on improving integration reliability for WCN-enabled networks. He revised the WCN client submodule, introducing serialization improvements through serde_json and migrating IRN node address handling from Multiaddr to PeerAddr to support better interoperability. His technical approach centered on Rust, leveraging dependency management and type migrations to streamline address serialization and reduce manual intervention during deployment. While the work was limited in scope to a single feature over one month, it demonstrated a solid understanding of Rust submodule management and targeted improvements to client stability and compatibility.
