  "family": "Liquidity provider economics",
  "summary": "A volume rebate the pool pays out of its own flow, settled on-chain at the end of each epoch, with no Merkle root, no off-chain calculation and nobody who can decline to publish it.",
  "description": "Volume rebates are how every venue rewards its best flow, and on-chain they are almost always a lie about where the computation happens. A team totals volume off-chain, posts a Merkle root, and traders claim against it. The rebate is real; the decentralisation is not. Whoever runs the script chooses who is in the tree, can publish late, can publish never, and is the only party who can tell you whether the number is right. The reason it is done that way is that per-trader accounting looks expensive, and in a continuous scheme it is: paying a share of a pot that is still growing means either an accumulator per trader or an unbounded loop. Epochs make it cheap. The hook skims `skimBps` of every swap into that epoch's pot and records the volume each account traded in it, which is two storage writes. Once an epoch has closed, both numbers are final, so a claim is one multiplication and a transfer:   payout = pot(epoch) * volume(epoch, account) / totalVolume(epoch) There is nothing to publish, nothing to compute off-chain, and nothing anybody can withhold. A trader who never claims simply leaves their share, and because a closed epoch's pot is fixed, that costs nobody else anything. Volume is attributed to whatever address the swap names in `hookData`, and this deliberately needs no signature. Naming somebody else credits them with volume you paid for, so the only thing a forged attribution achieves is giving away your own rebate. A swap that names nobody credits the router it came through, which lets a router run the rebate for its users and split it however it likes.",
  "priorArt": "Volume rebates, referral fees and loyalty discounts all exist as hooks, and all of them either discount at the point of trade (which cannot depend on a total that is not known yet) or settle against an off-chain Merkle root. Doing the accounting on-chain in closed epochs, so the rebate is a division anybody can verify and nobody can withhold, is the contribution here.",
  "limitation": "The rebate arrives after the epoch ends, so it is worth less than the same value taken off the trade, and a trader who wants a discount now is better served by a hook that discounts now. Epoch length is a real tradeoff rather than a parameter to shrug at: short epochs pay out sooner and let a single large trade dominate a small pot, long ones smooth that out and make the rebate feel remote.",
