Metamask gas assessment error and use of the Polygono testnet
As a metamask user, a popular cryptocurrency portfolio and a browser extension when executing transactions in the Ethereum network was probably found as an error of the gas estimate. In this article we will deepen what causes these errors and specify instructions for the use of polygon -testnet in Metamask.
What is the gas estimate error?
The gas estimation error occurs when Metamask is calculated the requested gas for the completion of a transaction, but does not correspond to the actual gas used by the transaction. This can happen for various reasons, such as:
- Failed network settings or configuration
- Software or extensions of the incompatible portfolio
- Inadequate funds in your account
- Network overload or high demand
Use of polygon tests with metamast
Polygon Testnet is a test test for Ethereum blockchain tests, with which developers can test and distribute intelligent contracts without risking the real world’s resources. When using polygon testnet in Metamask, it must be ensured that the following conditions are met:
- Software for the portfolio: Make sure that the metamask portfolio software is updated with the latest version.
- Network settings: Check whether the polygon account is connected to the Testnet network by checking the “Test” section of the Metamask settings.
- Gas boundary:
defines an appropriate gas limit for transactions, with the complexity of the code and the potential risks into account.
Analysis of the error message
The specified error message, {“code”: -32000, “Message”: “Change back” indicates an internal error JSON -RPC. This generally occurs if Metamask cannot carry out a transaction due to a logical error or gas problem.
Problem -solving steps
To solve the gas estimation error and the use of polygon testnet in Metamask:
- Check the network settings: Make sure that the polygon account is connected to the TestNet network by checking the “Test” section of the Metamask settings.
- Adjust the gas limit:
Reduce the gas limit for transactions to avoid excessive gas consumption.
- Check the complexity of the transactions: optimize the intelligent contract code for better performance and reduce the complexity of the transactions.
- Centers Metamask cache: occasionally stuck the metamask cache, which closes the browser extension or restarts the container software.
Diploma
Gas errors can occur when using polygon testnet in Metamask for various reasons such as the wrong network settings, incompatible portfolio software or inadequate funds. By following these problems of the problems and checking the Testnet configuration, these problems must be solved and polygon test network with metamask successfully used.
Remember to always check the official documentation of Ethereum and Metask updates to use the latest information on gas assessment errors and the use of polygon test networks in connection with the development of intelligent contracts.
