Binance co-founder Changpeng Zhao has proposed strengthening crypto wallet protection against address spoofing. He suggests embedding automatic recipient address verification in wallets, which would check the address before sending funds and, if necessary, warn the user or block the transaction. Zhao emphasizes that such verification can be performed through a standard blockchain query, so no complex technical solutions are required. In his view, it's more important to shift from recommendations to automated protection mechanisms that operate without user intervention.
Changpeng Zhao's Proposal to Enhance Security
The core idea is to integrate functionality into wallets that verifies the recipient address before sending funds and detects suspicious activity. If the address is linked to anomalies, the system should either alert the user or temporarily block the transaction pending further review. According to Zhao, this verification can be done via a standard blockchain query without needing complex architectural changes.

The Problem of Phishing Attacks
Address spoofing is a type of phishing where a scammer first sends the victim a small amount of cryptocurrency so that the address appears in the transaction history. Then, users who do not carefully verify the details copy the address from the history and mistakenly send funds to the scammer. This scheme is especially dangerous for those who frequently transact or do not use address validation mechanisms. As a result, victims rarely manage to recover stolen funds.
Phishing Loss Statistics
According to Scam Sniffer statistics, nearly 6,400 users faced phishing attacks in November, losing about $8 million. The source notes that the scale of attacks may increase by December. The article also mentions a recent case where an unknown investor lost $50 million in USDT, highlighting the magnitude of some incidents.
Why This Matters
If you mine cryptocurrency and occasionally transfer funds between wallets, the risk of address spoofing directly affects your transfers and holdings. For miners with many transactions or multiple addresses, errors in recipient details can lead to significant losses from a single failed transaction. Moreover, even successful attempts to recover funds are rare, so preventive measures are preferable to recovery attempts.

What To Do?
- Manually verify addresses and perform small test transfers when sending to a new address.
- Enable and update available wallet checks: if developers offer built-in address validation, activate it.
- Store significant amounts in cold wallets and use hardware devices to sign transactions.
- Monitor transaction history and check for unknown incoming amounts that might indicate "address poisoning."
- Regularly update wallet software and use trusted clients to reduce vulnerability risks.
