Metamask: Confirm buttons graying to metamascus when you are trying to interact with the Uniswap contract
As a building developer on a blockchaine ethereum, it is necessary to ensure that all interactions, including interactions with external contracts, are smooth and trouble -free. However, users have reported a common problem, especially when trying to perform Uniswap Swaps using metamascus. In this article, we dive into the cause of the problem and provide a solution.
problem:
When attempting to interact with the Uniswap Treaty using metamascus, users often encounter a confirmation button on the gray. This question arises because of how metamascus interacts with external contracts in the Ethereum network.
Why does the metamascus gray gray the confirmation button?
After a closer inspection, it is clear that the interaction of Metamask with UNISWAP contracts is largely relied on the functions of “et_requesta et_sendtransaction”. However, these features are not properly configured when interacting with external contracts.
Solution:
To solve this problem, we will need to update Metamask configuration settings to ensure the correct interaction with UNISWAP contracts.
1 Scroll down to the “Wallet” section and click the “Advanced Options” tab.
- Enable the functionality of the external requirement: Enable the “External Request Functality” switch on the “Advanced Options” tab. This will allow Metamask to apply for external functions, including contracts from external contracts such as Uniswap.
Next steps:
To confirm that your changes work as expected, follow these steps:
- Verify the UNISWAP Contract Interaction: Start the Metamask app and try to interact with the uniswap contract using
et_requestor ‘et_sendtransaction`. If you encounter any mistakes, this may indicate problems with your configuration.
- Test the local development environment:
If you are developing locally, make sure your Ethereum network is correctly set up and the Uniswap contract has been deployed in the network.
According to these steps, users should be able to solve the problem of confirming Greyed-Out when interacting with uniswap contracts using metamascus.
