Metamask: Token exchange does not work on Uniswap V2
I am a web3 developer and I encountered problems with the swap token on the decentralized exchange platform (Dex) Uniswap V2. While my exchange from ETH to my native token works correctly, I encountered problems with the inverse exchange from my native token to the hat.
The problem:
After conducting some problems, I identified the following problem:
- My Metamask portfolio has been updated to version 1.9.0 or later.
- I have a phrase of Metamasca seeds and I generated new private keys for both my ETH portfolio and for my wallet.
steps to reproduce:
To help others who could find similar problems, here are the steps I made:
- Metamask version: Make sure that the Metamask portfolio is performing version 1.9.0 or higher.

Potential causes:
Based on my research, I identified some potential causes for this problem:
* Network congestion:

If the network is experiencing a high congestion or large volumes of swap, it can cause problems with swap token.
* Configuration of the liquidity pool:
The liquidity pools erroneously configured can lead to errors during the swap token.
* Exchange rules: Make sure that the swap rules are set correctly on Uniswap V2.
Resolution:
To solve the problem, I recommend:
1
- Update the Metamask portfolio: Take the update of the Metamask portfolio to version 1.9.0 or higher.
- Check the configuration of the liquidity pool: Check that the liquidity pools are configured correctly on Uniswap V2.
Conclusion:
While I encountered some problems with the swap token on Uniswap V2, I am confident that a simple update to Metamask and some problems resolving the problems can solve the problem. If you are finding similar problems, try disabled the swap rules, update your wallet and check the configuration of the liquidity pool. With some changes, the swap tokens should work properly again!
