Metamask: Fake transaction found but failed
When I tried to deploy a smart contract on Remix.ethereum using Metamask on the Polygon network, I ran into an issue that prevented me from successfully completing the transaction. The error message indicated that a fraudulent transaction had been made, which prompted me to investigate further.
Problem
While reviewing my transactions, I realized that the fake transaction was indeed hacked, but it failed. Because of this, the contract was not deployed properly, and any attempt to run it ended in an error. The error message indicated a problem with the transaction that needs to be mined. Usually, it is solved by checking the blockchain for the admissibility of transactions.
Error message
Here is the detailed error message I encountered:
`a fake transaction was mined, but its execution failed''
This means that Metamask detected a fake transaction mining on the Polygon network, but it was not executed due to some other problem.
What went wrong
After further investigation, I discovered that the problem was the way my contract was deployed using Remix.ethereum. In particular, the code of the contract and the deployment script were configured incorrectly, which led to sending an invalid transaction to the Ethereum blockchain.
Solution
To solve this problem, I made the following changes:
- Contract Code Deployed Correctly: I have updated the contract code to make sure it is compatible with Remix.ethereum and deployed it correctly using a valid contract id.
- Updated deployment script
: I modified my deployment script to use the correcttxHash` field value for my ABI contract.
Result
Thanks to these changes, my smart contract should now be successfully deployed to Remix.ethereum using Metamask on the Polygon network. The fraudulent transaction that was detected has been removed, and the execution of the contract can continue as expected.
Conclusion
In this article, I demonstrated how a simple mistake when deploying a smart contract using Remix.ethereum with Metamask on the Polygon network resulted in an error message indicating that a fake transaction was mined but not executed. Fixing the deployment configuration and updating the script allowed me to resolve the issue and deploy my contract successfully.
