Polkadot.js Interface on a laptop plus two phones showing public chain exploration and transaction preparation screens.

Polkadot.js Interface public home screen with RPC connection and chain exploration controls.

(Problem)

Make RPC connection, storage queries and transaction preparation accessible in one browser interface.

(Approach)

I contributed the interface on a bootcamp starter repository, not the original chain architecture. React 19, TypeScript, Tailwind CSS and Polkadot.js API connect the interface to Westend, local Zombienet or a custom RPC endpoint, with wallet connection and transaction preparation controls.

(Result)

A public interface with chain-state, extrinsic and transfer screens. Screenshots show the public interface only; no transaction was submitted during capture. Transfer execution is not independently verified, and production readiness or original runtime design is not claimed.
