   - q: "Are sandwiches counted?"
     a: "Screened, not ranked. A sandwich's two legs both touch the pool, so they are the user's neighbours in the pool's own transaction sequence: another signer trading the same direction just before, and back just after, in the same slot or the next. Every hit is in the JSON with the attacker and both signatures. It is not a column because the share of swaps that can be screened depends on how busy the pool is, which differs per terminal. The victim's extra cost is not a separate line either: the front-run precedes the user's swap, so the arrival price already carries it inside the pool component."
   - q: "How is a swap attributed to a terminal?"
-    a: "By the fee it pays: every terminal transfers its fee to known wallets in the same transaction, and those wallet lists are the ones DeFiLlama's adapters use for volume, so attribution matches benches 201 and 267. Where the fee wallet is not enough: pump.fun's app and Banana Gun by their programs, Phantom by its fee token account, FOMO by the vanity account every FOMO transaction carries (its gas sponsor signs and is excluded as user), the EVM rows by the router the transaction was sent to (Binance Wallet from blocks read in full), the cross-chain rows by Relay's referrer or fee recipient."
