Ethereum: Format Issue When Signing and Verifying Messages Using a Safe Wallet
= 2.
Insufficient gas limit: Check that your wallet has enough gas to complete the signing process.
- Incorrect message length: Make sure that your message is not too long, as it may exceed the maximum allowed gas.
Solution: Handling GS026 Error
—————————–
To fix the GS026 error using ISignatureValidator.isValidSignature, you can do the following:
- Check signature buffer allocation
: Check that the signature buffer has enough space to complete the signing. You can do this by checking its length and allocating more space if necessary:
const signatureBuffer = new Uint8Array(2 * message.length); // Allocate enough space
- Check gas limit: Make sure that your wallet has enough gas to complete the signing process. You can check the current gas limit by calling
ethGasLimit' on the Ethereum blockchain:
const currentGasLimit = await ethGasLimit();
if (currentGasLimit < MAX GAS LIMIT) {
// Reduce gas limit if necessary
}
- Check message length: Make sure your message is not too long, as it may exceed the maximum allowed gas. You can check the message length and reduce it if necessary:
const maxLength = MAX GAS LIMIT / 8; // Pieņemsim, ka bloka lielums ir 8 baiti uz vienu gāzes vienību
if (message.length > maxLength) {
// Yes nepieciešams, samazinite ziņojuma garumu
}

Tālāk ir sniegts Solidity līguma piemērs, kas paraāda, kā rīkoties ar GS026 kļūdu:
“ stingrība

līgums SafeContract {
// Inicializējiet maku un iestatiet gāzes ierobežojumu
constructors() public {
_setGasLimit(2 ** 32); // Set a sufficient gas limit
// Allocate enough space for the signature buffer
const signatureBuffer = new Uint8Array(2 * message.length);
}
function _signMessage(message: bytes) internal return (byte memory) {
// Check if the gas limit is sufficient to perform the signing
assert(_gasLimit >= ethGasLimit(), “Insufficient gas limit”);
// Check the signature buffer allocation
if (signatureBuffer.length != 2 * message.length) {
request(0, “Invalid signature buffer”);
}
// Reduce the message length if necessary
if (message.length > MAX GAS LIMIT / 8) {
_reduceMessageLength(message);
}
// Parakstiet ziņojumu, izmantojot OpenZeppelin ERC721 marķiera līgumu
