## Bonding curve

The curve charges **1%** on buys and sells. Buy fees come out of the pair-token
input; sell fees come out of the gross pair-token output. The quote functions
already return fee-adjusted amounts:

- `quoteBuyFor` returns the launch-token output, fee, and any terminal refund.
- `quoteSell` returns the gross pair-token output, net output, and fee.

Fees are rounded up to the pair token's smallest unit. See
[Trade on the bonding curve](/guides/trade-on-the-bonding-curve) for executable
examples.

## Uniswap V4

After graduation, the pool charges **0.3%** per swap. Fees earned by Clank's
full-range liquidity position remain attached to its permanently locked
position until collected.

## Fee collection

Bonding-curve fees accrue in a shared escrow. V4 fees accrue to the locked
position. Anyone may trigger collection, but all funds go to the factory's
current `feeDestination`; callers cannot redirect them.

The factory also requires a zero launch fee, zero creator tax, and no buyback.
