Slippage and priority fees
Two knobs on every Solana trade: slippage and priority fee. Both live in your Quick-buy preset and in the trade page's advanced settings.
Slippage
The maximum price move you will tolerate between your click and the trade landing on-chain.
| Value | Behavior |
|---|---|
| Default | 20% |
| Floor | 0.1% — 0 is auto-corrected up to 0.1% |
| Minimum accepted | 0.01% — values below this are rejected |
| Maximum accepted | 100% — values above this are rejected |
On memecoins, slippage below 10% tends to fail during volatile moments. A typical range is 15–25%. Higher slippage means your trade is more likely to land but at a potentially worse price.
::: tip Why memecoins need higher slippage Prices on fresh pools can move several percent in a single block. A 2% slippage setting that works on majors will reject most Pump.fun trades. :::
High-slippage warning
If your slippage exceeds the platform's safe threshold, a High Slippage Warning dialog fires before the trade submits. You confirm to proceed. This catches accidental "100%" inputs that would let you buy at any price.
Priority fee
A SOL-denominated tip to the Solana validator who includes your transaction. Higher fee = earlier inclusion in a block.
| Setting | What it does |
|---|---|
| Low | Cheap, but may land later or fail during congestion |
| Medium / Default | Reasonable balance — fine for most trades |
| High | Priority inclusion, used when sniping or racing for a fill |
Priority fee is distinct from your slippage. Slippage is price tolerance; priority fee is speed.
High-priority-fee warning
If your priority fee looks unusually high — e.g. from a mis-typed 0.1 SOL tip — a High Priority Fee Warning dialog fires before the trade submits.
Where to set them
Both live in two places:
| Location | Scope |
|---|---|
| Quick-buy preset settings | Applies to every quick buy using that preset |
| Trade page — Advanced settings | Applies to the next market / limit order from that page |
Bribes (optional, per trade)
Some trades (sniper path, Pumpfun flows) accept an optional bribe parameter on top of the priority fee. This is an extra tip routed for faster inclusion in specialized paths. It is advanced — leave it at default unless you know why you're setting it.
How defaults interact with MEV mode
When you enable MEV protection in Secure or Reduced mode, transactions route through Jito or Nozomi. In that path:
- Your priority fee is still paid.
- Jito tips go to the bundle for priority.
- Only works for imported local wallets. Turnkey wallets (email/Google signup) fall back to standard RPC silently. Your fee is charged the same way.
Limits for limit orders
Limit orders snapshot slippage and priority fee at creation time, not execution time. Updating a preset later does not change queued limit orders. You cancel and recreate to change them.
Practical tuning
| Situation | Slippage | Priority fee |
|---|---|---|
| Buying a fresh Pump.fun launch | 20–30% | Medium–High |
| Trading a liquid, graduated pool | 10–20% | Default |
| Sniping — trying to land in the first block | 25%+ | High |
| Selling a thin-liquidity position | 20%+ | Default |
