METASK: How to avoid clicking “Accept” twice in Metask
As a user of the popular Metask extension for Ethereum wallets, you can encounter a problem in which you click the “APPROVED” and “Transferfrom” buttons, resulting in a rejected transaction. This can be frustrating and can lead to lost funds or unnecessary delays. In this article, we will explore how to avoid this problem using ETHERSJS.
Understanding Metamek behavior
Before you sink into solutions, it is essential to understand why Metamk could click the “Accept” button twice in certain situations:
- Tank transfers : When transferring a token from the wallet to a contract, Metask must approve both the transfer and approval of the token contract.
- Contractual interactions : Certain contractual interactions, such as appeal functions or updating status, may require more approvals.
The problem: By clicking “accept” twice
When clicking on the “Approve” button twice in Metask, it tries to approve two different chips simultaneously. This can lead to:
- Rejection of the token : The first approval could be rejected due to insufficient or balanced problems.
- Error execution of the contract : If the second approval fails, the contract can execute an incorrect or outdated state, causing additional problems.
Solutions:
To avoid clicking on “accept” twice in Metask, try these solutions:
1.
Use the “Transferfrom” option with “activated activated **
The “Transferfrom” function now includes an option to allow any token. You can activate this option by passing a Boolean value of True:
`JavaScript
IERC20 (token) .Transferfrom (msg.sender, address (this), sum, {allowanythen: true});
This will approve both the transfer and approval of the token contract, without clicking "acceptance" twice.
2
Alternatively, you can use the "approve" function to grant several simultaneous roles:
JavaScript
IERC20 (token) .approve ([contract.address, msg.sender], sum);
In this case, click "accepting" twice twice, because the first approval will be sufficient.
3.
Disable Automatic approval of Ethers.JS
You can disable the automatic approval of the ETHERSJS tokens using the "DisableauticalProved" option:
JavaScript
Ierc20 (token) .disableautomaticProved ();
However, this can have performance implications and is not recommended for the use of production.
4.
Update -va Metask Extension
As the last solution, ensure that the extension of Metask is updated. ETHERSJS Version 2.1.0 or later includes improved chip approval mechanisms.
Conclusion
To avoid clicking "Accept" twice in Metask, try to use the "Transferfrom" option with "allowanytoken" or "APROVE" option with "AllowaRole activated. In addition, deactivating the automatic approval of ETHERSJS tokens is a viable solution, but use this method with caution.
By implementing these solutions, you should be able to reduce the number of times to click “Accept” in Metask and minimize the risk of lost funds or incorrect contractual interactions.
additional tips
- Make sure that the metamark extension is installed and configured correctly.
- Use a secure wallet for the transfer of tokens to prevent unauthorized access.
- Test ETHERSJS implementation with small, controlled transactions before implementing them for production.
