OFAOrderFlowAuctionHook

EthereumRegistered

An order-flow auction hook for ETH/OFA pools that routes exact-in buy swaps to bonded fillers at the spot price when a qualifying filler is available, distributing the filler's surplus bid to OFA token holders. Falls back to a 2% baseline fee on unmatched buys and all sells, also forwarded to holders.
