How To Fix Swap Failed Error on Uniswap and Metamask

If you have ever received an error message saying that your Swap Failed, then there are a few reasons why this is happening. We can also help you to reduce this error so that you can successfully swap your tokens.

Whether you are using the Ethereum, Base, or Binance onchain marketplaces to swap your tokens on Uniswap, depending on certain conditions, your swap will fail.

Reasons you receive a Swap Failed message:

1. Network Congestion – If the price of Bitcoin reaches an All-Time High or is pumping higher in the market, Alt-Coins tend to follow that trend. That usually means the entire crypto market as a whole is trading at a higher frequency. When this happens, transactions and swaps tend to fail.
2. Low Slippage – If your slippage is too low, swapping token will fail at a larger rate. Tokens such as Meme coins tend to need a higher slippage in order for the swap to succeed.
3. Little to no Gas – No matter the network you use, they will charge a gas fee. If you do not have enough to cover the network’s Gas Fee, your swap will undoubtedly fail every time.

How to Fix or Avoid Swap Failed message:

1. Swap during low peaks or a down market – When the market is exploding in trading volume, due to Bitcoin’s sudden surge in price, you can expect delays and errors. Your swaps on Uniswap will succeed at a higher rate when the trading volume of the overall market slows down or drops. This method works best at times, especially when increasing the slippage fails to work.
2. Increase Your Slippage – The standard slippage rate is usually 0.5% to 2%. The more percentage you raise it to, the less amount of tokens you will receive from the swap. So the best strategy here is to raise the slippage slowly, using increments of 1 or 2. That way, when you reach a maximum of 18%, your swap should have already succeeded. If you increased your slippage to a higher number and your swap still fails, network congestion may be the issue.
3. Trade on a Centralized Exchange – If and when your decentralized exchanges continue to fail, then try using centralized exchanges (Gemini or Coinbase) which are used to dealing with high volume transactions and user activity. These platforms act as an intermediary between your transactions and the blockchain, preventing your swaps from failing.
