When a swap fails
What each swap error means and how to fix it, from fees and slippage to missing routes and busy networks.
A failed swap doesn't take your tokens. If the transaction reached the network, only the network fee was spent. Here's what each message means.
Before you swap
The Swap button tells you what's missing.
| Button or message | What to do |
|---|---|
| Select a token | Choose both tokens. |
| Enter an amount | Type how much to sell. |
| Insufficient [token] | You're selling more than you have. Lower the amount or tap MAX. |
| Insufficient [COOK or SOL] for fees | Add a little COOK (Cookie Chain) or SOL (Solana) to pay the network fee. |
| This token is still on the bonding curve and cannot be swapped yet. | The token is still in its launch sale. Buy it on MomoSwap from the token's page, or place a limit order. |
| No liquidity pool found for this token pair. | Nobody is trading this pair. Try going through COOK or SOL, for example sell for COOK first. |
| No swap route available for this pair. | Same as above. |
| Quote request timed out. | Try again, or try a smaller amount. |
| Aggregator is under maintenance. or Service temporarily unavailable. | The exchange service is down for a moment. Try again shortly. |
After you hold to swap
When a swap fails, the result sheet shows Swap failed and the reason. Tap Try again to reopen Confirm Swap with a fresh quote.
| Message | What happened | What to do |
|---|---|---|
| Price moved too much. Try increasing slippage to [x]% or higher. | The price moved more than your slippage allowed, so the swap stopped to protect you. | Raise slippage a little. See Slippage and price impact. |
| You don't have enough COOK for network fees + account rent. | Swapping into a token you've never held opens an account for it, which needs a small deposit. | Add a little COOK (or SOL on Solana) and try again. |
| Network was busy, please try again. | The swap took too long to land and expired. | Try again. On Solana, choose a higher Priority Fee. |
| Swap service is temporarily unavailable. | The exchange service didn't answer. | Wait a few seconds and try again. |
Still stuck?
- Check you're on the right network. See Switch networks.
- Refresh your balance on Home. A swap you thought failed may have gone through.
- Open the transaction from Activity and tap View on explorer for the full story.
If a swap shows as failed but your balance changed, contact Support with the transaction ID. Never share your recovery phrase.
