Jev Trader: Autonomous Micro-Arbitrage

A sub-second paper trading algorithm reading Binance and Coinbase order books to exploit cross-exchange spread anomalies.

01 / The Decision

Execute buy or sell order based on order book depth imbalance.

Jev sits between the incoming context and the next system action. Rather than generating lengthy, slow natural language that requires brittle regex parsing, Jev returns non-autoregressive, calibrated probabilities that downstream code can immediately execute.

I built a trading bot with Jev! Jev decides if it should "buy" or "sell", given the price feed of an asset pair, and executes real trades. It uses Monad to place the orders on Kuru's on-chain order book in every 300ms block. Demo link → jev-trader.vercel.app
