OKX X Layer · Uniswap V4 Hook · chain 1952

The V4 venue
Flap scoped but hasn't shipped.
So we built it.

FlapVenue reproduces Flap's creator tax as a beforeSwap hook delta that decays to zero over 30 days. It's a hook delta, not an ERC-20 transfer tax, so a Flap tax token can hold concentrated liquidity. Its live graduation path can't do that today.

Swap through the hook.

  1. 01

    You swap in the FlapVenue pool.

  2. 02

    beforeSwap skims the decaying creator tax from your input and holds it as ERC-6909 claims. The token itself carries no transfer tax.

  3. 03

    The concentrated-liquidity swap runs on the remainder.

  4. 04

    Creator and protocol claim their accrued tax anytime.

The tax is a hook delta, not an ERC-20 transfer tax. That's the whole reason a Flap tax token can sit in a concentrated-liquidity pool, which its live graduation path can't.
