Trading and liquidity
Fees, slippage, the launch floor and full-range positions.
The fee you pay
Every pool page shows the fee a small buy and a small sell pay right now, read live from the kernel. The fee is the pool's base fee plus whatever its blocks add, and it can rise with trade size (for example with a surge fee or dump damper). The kernel caps it at 50% during a pool's first 15 minutes and 10% after.
Placing a trade
- The trade panel quotes what you'll receive and a minimum after your slippage setting (0.5%, 1% or 3%).
- Approvals are for the exact trade amount; the router never gets a standing allowance.
- Trades expire after five minutes if not mined.
Why a trade can be refused
| Message | Why |
|---|---|
| One of this pool's rules refused the trade | A block refused it, for example a buy above the launch guard's per-trade cap. |
| The pool doesn't hold enough USDC | A sell on a launch would push the price below its launch floor. Try a smaller amount. |
| The price moved past your slippage limit | The price changed while your transaction was pending. |
| Not enough gas for this pool's rules | Your wallet set too little gas. Let it estimate gas. |
Providing liquidity
- Positions are full range and belong to your wallet. Add, withdraw a share, or collect fees at any time.
- You deposit an amount of the quote token; the matching amount of the other token is worked out at today's price.
- During a launch's guard window, outside liquidity is refused. No block can ever refuse a withdrawal: the kernel doesn't let blocks see removals at all.
