This project was part of Inter IIT Tech Meet, which is basically one of the toughest student tech battles. Companies sponsor challenges, and this one was given by Aptos. The task was simple to say but scary to do. Build a DEX on their chain.
The funny part is I knew almost nothing about Web3 when I joined. I just joined as a dev and I was honestly nervous. Everyone else felt like a pro, and we had this underdog energy at the start. But we kept grinding hard. We learned wallets, on chain state, and how the Econia protocol fits into trading.
We built a decentralized trading platform with wallet support, order placement, and real time APIs so the UI feels smooth. A lot of time went into debugging weird edge cases that only show up when real users click fast, cancel orders, or refresh at the worst time.
And yeah, we won 1st place. That moment was insane. It went from "are we even going to finish" to "wait, we won" in one night.
