What it does

POST /v1/wallet/mev_exposure

$0.30

Composite — samples recent blocks, per-tx heuristic, returns 0–100 exposure score.

POST /v1/tx/sandwich_check

$0.05

Was this tx sandwiched? Confidence (none/weak/medium/strong/confirmed) + attacker addr.

POST /v1/pool/recent_mev_density

$0.10

Pool's recent sandwich density (0.0–1.0) + sample sandwiches.

Methodology

Flag tx N as sandwiched iff:

  1. tx N-1 and N+1 share a from-address that differs from tx N, AND

  2. all three target a known DEX router on the same chain.

Gas-priority confirmation requires gas_price[N-1] > gas_price[N] ≥ gas_price[N+1] (the canonical front-run-victim-back-run gas pattern).

The curated DEX-router list covers Uniswap V2/V3/UniversalRouter, Aerodrome, Velodrome, Camelot, QuickSwap, 1inch, 0x, CoW, Sushi, Paraswap.

Chains

ethereum / base / arbitrum / optimism / polygon. Default base. Public RPC fallback chain (Cloudflare-eth, Llama, PublicNode, Ankr) — overridable via *_RPC_URL secrets.
