Substrate Contracts UI
Substrate Contracts UI is a key developer tool maintained by Parity Technologies (founded by Ethereum co-founder Dr. Gavin Wood) for the Polkadot ecosystem, which has a market cap exceeding $7B. The UI simplifies WASM smart contract deployment and interaction on Substrate-based blockchains used by dozens of major projects.
I contributed to the project by enhancing code quality through multiple open-source contributions and gained experience in building dApps with Substrate.

Substrate Contracts UI is a web application for deploying and interacting with WASM smart contracts on Substrate blockchains. I contributed to the project by making open-source improvements to enhance code quality and performance.
I developed UI components for interacting with WASM smart contracts to improve usability and efficiency. This work provided practical experience in building decentralized applications on the Substrate framework.
I made these contributions while learning about Polkadot's ecosystem and exploring their protocol and smart contract development. The project demonstrates open-source contribution to blockchain developer tooling and complements my experience with other blockchain technologies.
Achievements
- Enhanced code quality and performance through multiple open-source contributions.
- Developed UI components for seamless interaction with WASM smart contracts.
- Gained extensive experience in building dApps on the Substrate framework.
