Metamascus: Confirm the saturated metamascus button when trying to interact with UNISWAP Contract

As developer construction applications in Ethereum Blockchain, it is crucial to ensure that all interactions, including those with external contracts, are soft and nocE. However, users have reported the usual question, especially when they try to run uniswap swaps using metamas. In this article, we will enter the cause of the problem and provide a solution.

Ask:

When trying to communicate with the UNISWAP treaty with a metamic, users often find a confirmation button. This problem is due to the way in which metamas communicate with external contracts online Ethereum.

Why the Gray Metamascus button for confirmation?

After a more examined examination, it is clear that the interaction of metamas with UNISWAP’s contracts is largely based on the functions of ‘eth_request’ ieth_sentransación '. However, these functions are not configured correctly when they interact with external contracts.

Solution:

To solve this problem, we will have to update the METAMASK configuration configuration to guarantee adequate interaction with UNISWAP contracts.

  • Update Metamascus configuration: Go to the website [Metamascus] ( and go toconfiguration ‘>Advanced configuration'. Move down the 'Wallet' section and click the advanced options card.

  • Enable the functionality of the external application: inAdvanced options’, enable the ‘external application’ switch. This will allow MetamSk to request external functions, including those of external contracts such as UNISWAP.

Additional steps:

To confirm that their changes function as expected, follow these steps:

  • Check the interaction of the Uniswap contract: Start the Metamascus application and attempt the interaction with the UNISWAP contract using eth_request oreth_Sradransation. If you find any error, you can indicate problems with your configuration.

  • Try a local development environment: If you are developing locally, make sure your Ethereum network is correctly configured and the UNISWAP contract has been assigned online.

Following these steps, users must be able to solve the problem of the Siejan button for confirmation when the interaction with UNISWAP contracts using metamas.
