As an improvement to our previous token update process, users now can have their ownership of a contract address be verified and tied to their Etherscan account. Once this is done, the access to submit a token update request for the contract address that is owned by them will only be available to them, thus providing the owner with a sense of security that no other parties can try to update the token’s information or hijack the token’s page.
(Please take note that every token update request will be reviewed and is subject to approval before it can be published on our platform)
