Metamask Error: Unable to exchange ERC20 tokens on UNISWAP

I have encountered an issue with my Metamask configuration that prevents me from successfully exchanging simple ERC20 tokens on the UNISWAP router. In this article, I will explain the error and provide potential solutions to resolve it.

Problem

After adding liquidity to a token pair, such as ERC20 tokens on UNISWAP, I received the following error:

Too few received

This error occurs because Metamask is not sending enough tokens to complete the transaction. Therefore, the exchange attempt fails.

Why is this happening?

When you add liquidity to a token pair on UNISWAP, your MetaMask account receives a certain amount of tokens as part of the initial liquidity addition process. However, this amount may not be enough to support the desired exchange amount. In most cases, the default amount of tokens sent to complete the exchange is around 1-2% of the token supply.

Potential Solutions

To resolve this issue, you can try the following solutions:

1. Increase the initial liquidity amount

You can increase the initial liquidity amount by using the “–liquidity” option when adding liquidity to UNISWAP:

metamask add liquidity --liquidity 1000000 




Replace with the desired token supply

This will send more tokens to complete the transaction, increasing the probability of a successful transaction.

2. Use the --swap option

You can also use the --swap option when adding liquidity to UNISWAP:

metamask add liquidity --swap --amount 1000000 
Replace with the desired amount of tokens

This will send a larger amount of tokens to complete the transaction.

3. Check the token supply

Make sure you are using the correct token pair and amount on UNISWAP. If you traded from a different pair or token, try adding liquidity again for that specific pair.

Additional Tips

• Make sure your MetaMask account has enough balance to support the transaction amount.

• Monitor the transaction details to ensure it is successful.

• Be patient and try adding liquidity again if the initial attempt fails.

By following these solutions or tips, you should be able to resolve the “Too little received” error when exchanging ERC20 tokens on UNISWAP.
