0xf645eedf: ECDSAInvalidSignature

error ECDSAInvalidSignature()

What it means

A transaction that reverts with the raw data 0xf645eedf hit the custom error ECDSAInvalidSignature, defined in OpenZeppelin 5. The explorer shows the hex because it does not have the contract's ABI to translate it.

A signature the contract tried to verify is malformed. Common with signed orders, permits, and meta-transactions that were built incorrectly or corrupted in transit.

How to fix it

Re-sign the message or order from the dapp rather than reusing a stored signature. If it persists, the dapp is building the signature payload wrongly.

Paste the hash and we decode the revert against the contract itself, including the values inside the error, free.

Every selector on this page was computed as the first 4 bytes of keccak256 of the signature shown. A selector identifies a signature exactly; on rare occasions two different signatures share one, so the transaction decoder is always the more precise answer.
