CZ said block explorers should completely filter spam transfers tied to address poisoning scams, arguing current displays of zero-value transactions can leave users exposed to deceptive wallet history entries.
CZ escalated criticism of how block explorers handle address poisoning scams, saying on X that Etherscan should fully filter malicious spam transfers instead of continuing to display zero-value transactions. He stated that Trust Wallet already applies this kind of filtering. The comments build on Etherscan’s earlier warning that address poisoning uses lookalike wallet addresses and negligible transfers to manipulate transaction histories, and follow its statement that such attacks are becoming more automated and widespread.
