Addressing timestamp-related signature issues in user operations
Your user operation’s signature is invalid due to a timestamp mismatch. This occurs when:
block.timestamp
is later than the validUntil
timeblock.timestamp
is earlier than the validAfter
timeThese time constraints are derived from the validationData
(a bytes32
field) returned by the smart account’s validateUserOp
function.
For Time-Sensitive Operations:
validAfter
and validUntil
settingsFor Standard Operations:
validAfter
and validUntil
to 0
Pro Tip: For non-time-sensitive operations without aggregators, simplify your validateUserOp
function:
uint(0)
for valid signaturesuint(1)
