firsttx

Inspiration

I built FirstTX because I saw a clear gap in on-chain trading: most people do not lose because they lack information, they lose because they cannot execute fast enough under pressure. I wanted to create a training ground where people can build that execution skill before risking real capital.

What it does

How we built it

FirstTX is a reaction training platform for on-chain traders. In the app, users read a live-style signal feed, identify the correct token among noise and decoys, and act before the timer runs out. It tracks reaction time, accuracy, consistency, and rank progression across solo training, endless mode, duels, and simulated wager mode.

Challenges we ran into

Accomplishments that we're proud of

I built FirstTX as a full-stack web app using React and Next.js for the frontend, Supabase for authentication, profiles, rankings, and match history, and custom gameplay systems for timing, difficulty scaling, and progression. I designed the gameplay around realistic signal parsing so the experience feels closer to the speed and chaos of real on-chain markets.

What we learned

One of the biggest challenges was balancing the game so it felt skill-based instead of random. I spent a lot of time tuning timers, round flow, difficulty progression, rank gains, duel fairness, and reward logic. I also had to solve issues around auth, persistence, realtime multiplayer state, and keeping the UX polished across different devices and sessions.

What's next for firsttx

Next, I want to make the training loop deeper and the competitive side stronger. I plan to improve the realism of the signal environment, expand progression and ranking systems, push wager-based gameplay further, improve wallet integration, and eventually broaden FirstTX beyond a single ecosystem so it can train execution across more parts of crypto.
