Spot Trading Cryptocurrency App (Sponsor-directed Prototype)

Description

This full-stack web app was a group project developed for our sponsor, dYdX Trading Inc., to prototype a spot trading cryptocurrency app for inscription tokens.

Role

I was responsible for the front-end development, using React, TypeScript, and Ant Design to build an intuitive user interface. I integrated Chart.js for real-time market data visualization and created API endpoints for spot trading and the NFT marketplace. Additionally, I developed an indexer to gather blockchain data for inscription tokens, although it was not used in the final product due to performance limitations. I also handled the actual Bitcoin transactions on the platform, implementing the back-end logic using BitcoinJS and Blockstream Esplora.
