Metamask error: unable to change the ERC20 tokens at Uniswap

I found a problem with my metamask configuration that is preventing me from successfully switching tokens ERC20 in the Uniswap router. In this article, I will explain the error and provide potential solutions to solve it.

The question

After adding liquidity to a pair of token, such as the ERC20 tokens in Uniswap, I have received the following error:

`

Very little received

`

This error is occurring because Metamask is not sending enough tokens to complete the exchange. As a result, the attempt to exchange fails.

Why does this happen?

When you add liquidity to a token pair to Uniswap, your metamask account receives a certain amount of tokens as part of the initial liquidity process. However, this value may not be sufficient to support the desired exchange value. In most cases, the default amount of tokens sent to complete the exchange is about 1-2% of the token supply.

Potential solutions

To solve this problem, you can try the following solutions:

1. Increase the value of the initial liquidity

You can increase the initial liquidity value using the --dealing option when adding liquidity to Uniswap:

`Bash

Metamask Add liquidity -Foom 1000000

Replace with the desired token supply

`

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

2. Use the --swap option

Alternatively, you can use the --swap option by adding liquidity to Uniswap:

`Bash

Metamask Add Liquidity –Swap – -Amount 1000000

Replace with the desired token supply

`

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

3. Check the token supply

Make sure you are using the correct token pair and your UNISWAP supply. If you have changed a different pair or token, try adding liquidity to this specific pair.

Additional Tips

• Make sure your metamask account has enough balance to support the exchange value.

• Keep an eye on the transaction details to ensure that it is successful.

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

By following these solutions or tips, you can solve the “very little received” error by changing the ERC20 tokens in Uniswap.
