FAQ

Questions received last month:

Why isn't the ENS Name Tag displayed on the contract address page?
Currently on Etherscan, the ENS name tag for a contract address will only be displayed if the setNameForAddr function is called during the ENS reverse resolution setup. Learn how to set primary name for a contract here.

How does an address poisoning attacker spoof a token transfer event?
An attacker targets & mimics a high-value token transfer by deploying a spoofed token, creating an address similar in the first & last few characters, and initiating the transferFrom function with matching token value.
