Adaptive MEV Sandwich Defense & Counter-Arb

Active mempool adversarial searcher neutralization and dynamic slippage constraint enforcement.

Executive Summary · Key Invariants

MEV sandwich defense analyzes pending mempool transactions in real time to calculate whether an adversarial searcher can profitably sandwich a trade. By formulating the attacker's profit function in Datalog, our engine calculates the maximum safe slippage tolerance ($S_{safe}$) and routes orders through private relays if attack viability is detected.

Formal Datalog Specification & Correctness Proof

The following first-order declarative rule guarantees non-reverting execution by validating token balance conservation and minimum net profit constraints.

Datalog Rule: mev-sandwich-shield

datalog

sandwich_vulnerable(TxHash, AttackerProfit) :-
    mempool_pending(TxHash, Pool, InAmount, MaxSlippage),
    pool_reserve(Pool, Rx, Ry),
    simulate_frontrun(InAmount, Rx, Ry, FrontrunDelta),
    AttackerProfit := FrontrunDelta - gas_cost(),
    AttackerProfit > 0.05.

Execution Logic & Pipeline Architecture

1. Sniff raw transaction payloads from Ethereum mempool. 2. Engine executes speculative pool state transitions for pending transactions. 3. Flag high-risk transactions before block mining. 4. Broadcast dynamic counter-transactions or divert to Flashbots Protect.
