Verify Address Ownership process involves verifying the ownership of a smart contract address with the Ethereum address used to create the smart contract, and then link the contract address to the owner's Polygonscan account.

Previously, Polygonscan adopts a signed message method where the owner of the smart contract will need to sign a message claiming ownership of the particular contract for every submission.

The signed message is a security step to ensure only the owner/creator of a contract address can update the token information of the contract itself.

Moving forward, once a user has claimed ownership of a contract address, the user will be able to update their token information and address name tag without needing to sign a new message for future submissions.

The contract owner can verify ownership of multiple addresses under a single Polygonscan's account.

To have an address verified, the user would need :

1. A Polygonscan account

2. To have signed a message once to verified ownership of each address

Features available upon verification of address ownership :

1. Update Token Info

2. Update Address Name Tag / Labels
