What is Verify Contract Address Ownership?

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

Previously, Etherscan 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 Etherscan’s account.

To have an address verified, the user would need :

A Etherscan account
To have signed a message once to verify ownership of each address

Features available upon verification of address ownership :

Update Token Info
Update Token Sales Info
Update address Name Tag / Labels

How to Verify Token Ownership?

The Verify Address Ownership feature is only available for Smart Contract Addresses and applies to all EVM-chain explorers built by Etherscan where the feature is available
