ORRO, fees that wait for the liquidity
A Uniswap v4 hook that streams swap fees over an orbit, weighting liquidity by the time it remains in range.
Field notes
ORRO routes each swap’s fee into a forward stream lasting one orbit, displayed here as one hour, rather than distributing it instantly at the swap. Positions earn according to liquidity multiplied by the seconds they remain in range; a position that enters and exits inside one block receives zero weight. The page describes an accumulator-and-timestamp design and reuses the pool’s tick bitmap for range accounting. Its displayed pool currently has no liquidity, so the mechanism is more fully documented than demonstrated in the extract.
