# Blockchains

WalliD allows you to add blockchain asset ownership verifications to your user data verification flows

The dashboard will allow you to get the smart contract data of the tokens and NFTs you wish to validate and establish conditions  (eg. user owns NFT #ID 001) for a successful verification.
