# Check signature-Typed Data

To verify a typed data signature it is required to insert the exact same parameters that was used in the [Sign Type Data](https://docs.novabloq.com/web3-metamask/elements-details/web3-and-metamask/sign-typed-data) action. \
Changing any character will result in incorrect result.\
\
The events and states are the same as for regular [Check signature](https://docs.novabloq.com/web3-metamask/elements-details/web3-and-metamask/check-signature) action, so use those.
