Metamask: False Transaction Mined but Execution Failed
When I tried to deploy a smart contract on Remix.ethereum using Metamask on the Polygon network, I encountered an issue that prevented me from executing the transaction successfully. The error message pointed to a false transaction being mined, which led me to investigate further.
The Issue
Upon reviewing my transactions, I noticed that the false transaction was indeed being mined, but the execution failed. This resulted in the contract not being deployed as expected, and any attempts to execute it would fail with an error message. The error message indicated a problem with the transaction being mined, which is typically resolved by verifying the blockchain for valid transactions.
The Error Message
Here’s the detailed error message I encountered:
false transaction mined but execution failed
This indicates that Metamask detected a false transaction being mined on the Polygon network, but it was not executed due to some other issue.
What Went Wrong
After further investigation, I discovered that the problem lies in the way my contract is deployed using Remix.ethereum. Specifically, the contract’s code and deployment script were not correctly configured, leading to an invalid transaction being sent to the Ethereum blockchain.
Solution
To resolve this issue, I made the following changes:
- Correctly Deployed Contract Code: I updated my contract code to ensure it was compatible with Remix.ethereum and correctly deployed 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 now be successfully deployed on Remix.ethereum using Metamask on the Polygon network. The false transaction being mined was resolved, and the execution of the contract can proceed as expected.
Conclusion
In this article, I demonstrated how a simple mistake in deploying a smart contract using Remix.ethereum with Metamask on the Polygon network resulted in an error message indicating a false transaction being mined but not executed. By correcting my deployment configuration and updating my script, I was able to resolve the issue and successfully deploy my contract.
