Swaps

Swaps (spot trading) vs limit orders

Swaps are market orders. They execute instantly.

Limit orders execute only when the price hits your target. See Limit orders.

Before you swap

• You need a wallet. See Setting Up Your Wallet.

• Always keep extra SOL in your wallet balance for covering network fees.

• New tokens may require a one-time token account creation fee.

Accessing swaps

• Main menu: 🟢 Buy or 🔴 Sell

• Commands: /buy or /sell

Token → token swaps use the same flow. Change both input and output tokens.

What you can do

• Buy: swap SOL → token.

• Sell: swap token → SOL.

Inputs you control

• Token: what token you want to buy or sell.

• Amount: what you spend or receive.

• Slippage tolerance: how much price movement you accept.

Tighter slippage reduces bad fills. It increases failure risk.

How execution works

When you confirm, FatCat builds and submits a transaction that:

• Finds the best route across liquidity sources.

• Splits across venues when needed.

• Uses routing with MEV protection to reduce sandwich risk.

• Settles output tokens back to your wallet.

Make a swap

5

Confirm

The trade executes on-chain right away.

What happens after you confirm

• Submission: the swap is sent to Solana.

• Execution: routing chooses the best available path.

• Settlement: output assets land in your wallet.

• Failure cases: the swap can fail on slippage, liquidity, or fees.

Troubleshooting

Swap failed (slippage)

• Increase slippage tolerance a bit.

• Reduce size in thin liquidity.

• Avoid fast candles and big news moves.

Swap failed (insufficient SOL)

• Keep extra SOL for fees.

• You may also need SOL to create a token account once.

Output is lower than expected

• Check price impact before confirming.

• Tighten slippage when markets are calm.

• Prefer smaller chunks in low liquidity.
