Etherscan issued a warning that address poisoning has surged by 612% after the Ethereum Fusaka upgrade

Etherscan posted on social media that there were approximately 17 million poisoning attempts on Ethereum from 2022 to 2024, affecting 1.3 million users, with confirmed losses of at least $79.3 million. After the Fusaka upgrade (December 3, 2025), transaction costs will decrease significantly, and dust transfers will explode, increasing by 612%.

Etherscan recommends that users take the following measures:

• Always manually verify the complete target address before transferring (most important)
• Add private name tags for frequently used addresses + use ENS domain names
• Enable the Etherscan Address Highlight feature · Pay attention to pop-up reminders when copying addresses.
