Contributions summary:Sam primarily contributed to the front-end of the Polkadot/Substrate UI application, specifically focusing on adding and configuring network endpoints for various testnets and mainnets, including Kylin, Pichiu, and Imbue. They modified UI configuration files (colors, logos, and endpoints), and adjusted para IDs for parachains, which allowed users to connect to different blockchain networks through the UI. This work ensured the UI was up-to-date with new networks and compatible with the Polkadot ecosystem.
