Fee Structure

FatCat charges product fees on trades and positions.

Some actions run on Jupiter programs, which add Jupiter program fees.

All on-chain actions also pay Solana network fees.

Fees shown here are current as of Feb 10, 2026.

You’ll always see the exact upfront cost in the in-app approval screen during approval.

You pay fees at approval/execution.

Fee types (what you’re paying for)

• FatCat fees: product fees charged by FatCat.

• Jupiter fees: program fees charged by Jupiter for specific features (limit, DCA, Perps).

• Solana network fees: paid to the network for transactions. These can’t be avoided.

Where you’ll see fees

You’ll typically see fees in two places:

• An estimation in the bot summary: the preview before you confirm.

• In the approval prompt: the final review screen (and sometimes multiple transactions).

If you’re unsure, treat the bot summary as an estimate.

Treat the approval prompt as the source of truth.

Fee summary (FatCat vs Jupiter)

Spot (swaps, limit, DCA)

Action	FatCat fee	Jupiter fee	When you’re charged
Market swap	0.1%	—	FatCat: upfront
Limit order	0.1%	0.1%	FatCat: upfront / Jupiter: at fill
DCA order	0.1%	0.1% per execution	FatCat: upfront / Jupiter: each execution

Limit and DCA run on Jupiter programs.

That’s why they can include Jupiter fees.

Perps

Timing glossary:

• Upfront: charged before execution.

• At fill: charged when the order executes.

• At approval: shown when you approve the action.

• Deducted: taken from collateral or trade amounts.

What can change your final cost

Fees are predictable. Execution costs can move.

• Solana network fees: can rise with congestion (priority fees).

• Price impact / slippage: depends on liquidity and size at execution.

• Perps borrow fees: accrue while the position stays open.

• Limit / DCA behavior: Jupiter fees apply on actual fills/executions (partial fills can mean partial fees).

Refunds, cancellations, and “why did I pay a fee?”

Some fees are charged upfront or at approval.

Those fees are usually non-refundable, even if you cancel later.

Why do I see multiple fees on one action?

It’s normal to see a mix of:

• FatCat fee (product fee).

• Jupiter program fee (if the feature runs on Jupiter).

• Solana network fees (to submit transactions).

These are separate payees and separate fee rules.

Why did I pay a fee if my transaction failed?

Solana network fees are paid when a transaction is processed.

That can happen even if the transaction fails due to slippage or simulation errors.

Market swaps

• FatCat fee is charged upfront.

• Solana network fees are paid when the transaction is sent.

• If the transaction fails, network fees can still be paid.

Limit orders

• FatCat fee is charged upfront when you place the order.

• Jupiter fee is charged only if it fills.

• Cancelling an order stops execution. It does not undo already-paid fees.

DCA orders

• FatCat fee is charged upfront when you set up the DCA.

• Jupiter fee is charged per execution.

• Cancelling stops future executions only.

Perps

• Perps fees are based on notional size.

• FatCat charges 0.08% only when you open a position. It’s shown at approval and is non-refundable once approved.

• Borrow fees accrue while the position is open.
