NEI DexArb Overview

Automated arbitrage bot finding price differences between decentralized and centralized exchanges.

NEI DexArb Overview.

NEI DexArb finds and executes arbitrage opportunities — price differences for the same asset between decentralized exchanges (DEX) and centralized exchanges (CEX). Buy low on one, sell high on the other, profit the spread.

How Arbitrage Works.

  1. Token X trades at $1.00 on Uniswap (DEX).
  2. Same token trades at $1.03 on Binance (CEX).
  3. Buy on Uniswap, sell on Binance. Pocket $0.03 minus fees.

What DexArb Automates.

  • Scanning. Monitors price feeds across 10+ DEXs and 5+ CEXs continuously.
  • Calculation. Factors in: gas fees, swap fees, slippage, transfer time.
  • Execution. When profitable spread found, executes both sides atomically.
  • Reporting. Logs every opportunity: taken, skipped, and why.

Realistic Expectations.

Arbitrage spreads are small (0.1-0.5%) and compete with other bots. Volume and speed matter more than individual trade size. Consistent small profits compound.
