A preset bundles your execution settings. Each trading surface shows its active preset next to the buy controls. Tap it to switch between P1, P2, and P3, or open Edit Presets to change what they mean.
The preset selector: P1 on Auto, P2 and P3 with manual values, Edit Presets below
New to slippage, priority fees, and tips? Leave P1 as it ships and trade. It is built to be the answer for most people: P2 and P3 ship with fixed manual values rather than Auto: tighter slippage, larger fees. Use them when you want a trade to behave the same way every time regardless of conditions. One habit worth having: raise slippage only when a trade keeps reverting on a thin market, and remember it is the worst price you are agreeing to accept, not a target. Signed transactions are submitted through Primal’s managed relay; preset settings never select a browser RPC endpoint.

The settings panel

Preset Settings: slippage, priority fee, tip, max auto fee, and Anti-MEV Off/Red/Sec
Each preset holds its own copy of every setting. The pink Auto pills and the Anti-MEV row are the two controls that matter most; the rest is manual override for when you want exact numbers.

​
Auto mode

Set fee, tip, or slippage to Auto and the terminal resolves them at trade time from live network conditions. Priority fees target fast inclusion at the current market rate. Tips track what protected execution currently costs. Slippage adapts to the pool. The Max auto fee ceiling always wins: Auto never spends past it.

​
MEV protection

A sandwich attack sees your buy in the public mempool, buys before you land, and sells into your fill. The Anti-MEV setting controls whether your transaction is ever visible there. Three modes: Two guarantees behind Red and Sec:
  • No public fallback. Ever. If the protected lane cannot land your transaction, it fails. The terminal never silently retries through the public mempool, because a retry there is exactly the exposure you paid to avoid. A failed transaction costs at most its network fee; a sandwich costs far more.
  • Honest confirmation. Bundles can land late. Sec trades are watched for a longer confirmation window, so a fill that lands at the edge is reported as the trade it is, not falsely declared dead.
The tip setting funds the protected lane. On Auto it tracks what protected inclusion currently costs; the Max auto fee ceiling still applies.
