README.md

Atomic cross-DEX arbitrage with sub-block execution. Designed to be owned by exactly one operator.

Overview

Arb Engine scans pairs across DEXs, builds atomic multi-hop routes, and executes within the block. Includes a backtesting harness and hard risk caps.

Why 1/1

An arbitrage edge decays with every additional operator running it. This listing exists as a single edition for that reason, so buying it closes it.

Quick start

cargo build --release, configure pools and risk caps, then run against devnet first. Mainnet requires a funded keypair and a low-latency RPC.

Requirements

  • Rust toolchain
  • Low-latency Solana RPC
  • Funded keypair (mainnet)

Stack

Rust

Pinned dependencies, no lock-in to the seller's accounts. Deploy scripts included.

How it works, end to end

1. ingest → stream events from source
2. process → parse, score, decide
3. act → submit transaction / render output
4. log → record outcome + metrics

What it has

  • Atomic cross-DEX routing
  • Sub-block execution
  • Backtesting harness
  • Risk caps

Can be improved

  • Single-region RPC assumed
