Why can't I swap this token?

Before a swap on an EVM network, FxWallet checks the tokens, the price and what the swap would do on the blockchain. When a check finds a serious risk, it stops the swap or asks you to confirm. Find what you see below.

The Swap button names a risk

FxWallet won't let you buy a token that its security data flags as a scam. The button shows the risk instead of Swap, such as Honeypot, Self-Destruct Function or Fake Token, and can't be tapped. Don't buy the token anywhere else either: tokens like these usually can't be sold. See Tokens you can't sell.

FxWallet also won't swap a token whose tax would take most of what you swap. The button then shows the token's tax.

The Swap button stays grey

• The price impact is too high. The amount is too large for the token's liquidity, and FxWallet shows the estimated loss above the button. Swap less, or split it into several swaps. See Price impact.
• No Liquidity. No route can swap this pair right now. Try again later, try another amount, or swap through a common token such as USDT or ETH.

FxWallet asks you to confirm

When the risk is serious but not certain, FxWallet shows an alert with the estimated loss: for example High-Risk Token Alert when you sell a token flagged as a scam, or Unknown Trade Value Alert when it can't value one of the tokens.

warning

Confirm only if you're sure of both tokens and the amount: the loss shown can be real. To go ahead, tick I understand the risks and want to proceed, then tap Confirm Swap.

A confirmation covers one quote. If the quote changes, FxWallet asks again. If FxWallet couldn't finish its checks, it offers Retry and Continue Anyway: tap Retry first.

The confirmation screen stops the swap

Before you confirm a larger swap, FxWallet simulates it to see what you'd really receive:

• Simulation predicts failure. Execution blocked, or Execution blocked to prevent severe loss: you can't confirm this route. Go back and pick another route, swap less, or try again later.
• Significantly worse than quoted price: you'd receive much less than quoted. To swap anyway, use Slide to Confirm Swap.
• Simulation unavailable: FxWallet couldn't check the swap. The quote is marked Unverified Quote, and the button says Proceed to Swap.

These checks cover swaps on one network. Bridges, and swaps between networks, don't get them.
