Metamask: Fake Transaction Mined but Failed to Execute
When I tried to deploy a smart contract on Remix.ethereum using Metamask on the Polygon network, I encountered an issue that prevented the transaction from successfully executing. The error message indicated that a fake transaction was mined, which prompted me to investigate further.
The Issue
While reviewing my transactions, I noticed that the fake transaction was indeed mined, but the execution failed. This resulted in the contract not being deployed as expected, and attempts to execute it failed with an error message. The error message indicates an issue with the transaction mining, which is usually resolved by verifying that the blockchain has valid transactions.
The Error Message
Here is the detailed error message I encountered:
fake transaction mined but execution failed
This indicates that Metamask detected a fake transaction on the Polygon network, but it was not executed due to some other issue.
What went wrong
Upon further investigation, I discovered that the problem lay in the way I deployed my contract using Remix.ethereum. Specifically, the contract code and deployment script were not configured properly, which resulted in an invalid transaction being sent to the Ethereum blockchain.
Solution
I made the following changes to resolve the issue:
- Properly deployed contract code: I updated my contract code to ensure it was compatible with Remix.ethereum and deployed it properly using a valid contract ID.
- Updated Deployment Script
: I modified my deployment script to use the correct txHash field value for my contract’s ABI.
Result
With these changes, my smart contract should successfully deploy to Remix.ethereum using Metamask on the Polygon network. The mined fake transaction has been resolved, and the contract execution can proceed as expected.
Conclusion
In this article, I demonstrated how a simple error when deploying a smart contract using Remix.ethereum and Metamask on the Polygon network resulted in an error message indicating that a fake transaction was mined but not executed. By correcting the deployment configuration and updating my script, I was able to resolve the issue and successfully deploy my contract.
