- Binance’s CZ calls for wallets to block poison addresses.
- The $50M theft spurs industry-wide security changes.
- Address poisoning remains a critical crypto security challenge.
Changpeng Zhao proposed that wallets block ‘poison addresses’ by default after a $50M USDT hack on December 20, 2025, via address poisoning.
Address poisoning poses significant risks to crypto security, highlighting vulnerabilities the industry must address to protect users from theft.
Following a $50M USDT theft via address poisoning, Binance co-founder CZ suggests wallets automatically block “poison addresses” by default. The incident involved USDT transferred to a scam address after a deceptive test transaction.
Changpeng Zhao, the co-founder of Binance, addresses the crypto world by urging that all wallets implement blocking of “poison addresses” by default. This proposal comes in the wake of the recent high-profile theft.
Immediate effects on the cryptocurrency industry are profound. The proposed changes could set a new standard for wallet security, protecting investors against similar scams. The theft caused a significant stir, leading to urgent discussions on increasing security.
The theft had no reported impact on the broader market’s liquidity or valuation. However, industry experts are raising the alarm about the growing sophistication of such attacks and advocating improvements in blockchain security protocols.
This event adds to the ongoing debate over cryptocurrency wallet security. With historical precedents like the $68M WBTC incident, which prompted Binance’s algorithmic intervention, systemic reforms are necessary to prevent further losses. CZ’s vision aims to eliminate such threats from the ecosystem by leveraging technology.
“All wallets should simply check if a receiving address is a ‘poison address’, and block the user.” – Changpeng Zhao (CZ), Co-founder and former CEO of Binance
Potential outcomes from this proposal may include a wider adoption of advanced security measures across the sector. Historical data shows increased phishing and hacking incidents, emphasizing the need for enhanced defenses. Blocking systems could reduce future financial risks significantly.
