Fees

Every buy and every sell pays 1% of its HYPE value. The pool's LP fee is 0, because all of its liquidity is the locked curve; the hook takes the fee itself, in HYPE, on both sides of the trade.

Uniswap V4 applies a per-pool protocol fee, capped at 0.1%. Arcadia reads that rate from the pool at swap time and takes the remainder, so the base stays 1% whatever Uniswap V4 sets: Uniswap's share comes out of the 1%, and the rest is Arcadia's.

On top of the base, each coin carries the fee its creator chose at launch, from 0% to 10% in steps of 0.1%. It is shown on every list, every quote and the coin's page.

Of the creator fee, 80% is the creator's and 20% is Arcadia's. The creator's part accrues to the launching wallet and is claimable at any time.

An example: a 100 HYPE buy of a coin with a 3.0% creator fee, on a pool with no Uniswap protocol fee.

Arcadia's whole share (the base less Uniswap's part, plus 20% of every creator fee) goes to the ArcadiaVault, which buys $ARCADIA in its Arcadia pool and burns it. $ARCADIA

A creator can lower their coin's fee from their profile at any time. It takes effect from the next trade and can never be raised again.
