High-impact swaps settle at a price only Chainlink VRF decides — after the trade is already locked in. Small swaps never notice a thing.
Every swap is classified before it ever executes. Small ones move on immediately. Large ones — the ones actually worth sandwiching — get routed somewhere a bot can't price in advance.
A high-impact swap locks its intent on-chain and requests randomness from Chainlink VRF. Nothing executes yet — there's nothing for a bot to price in advance.
Chainlink's VRF node returns a number nobody — not even the trader or the hook — could predict at commit time. It selects 1 of 5 pre-committed price boundaries.
The swap executes bounded by the randomly-selected price limit. The exact boundary was unknowable until after the trade was already locked in.
A small premium on the settled amount is donated straight into the pool's fee-growth accounting — paid to LPs, proportional to their share, not to the hook.
