Binance co-founder Changpeng Zhao has urged the crypto industry to adopt unified defenses against address poisoning scams following a $50 million theft involving a single mistaken transaction. The incident, which occurred on December 20, highlights how even experienced traders remain vulnerable to increasingly sophisticated wallet manipulation tactics.

Address poisoning is a form of phishing that exploits how crypto wallets display shortened addresses. By mimicking the first and last characters of a legitimate address, attackers trick users into sending funds to fraudulent destinations that appear familiar at a glance.

How the $50 Million Scam Unfolded

According to on-chain data, the victim began with a standard precaution: a small test transfer. On December 20, the trader sent 50 USDT to what they believed was the correct address. Twenty-six minutes later, confident the destination was verified, they transferred 49,999,950 USDT.

Unbeknownst to the sender, the second transaction went to a scammer-controlled address. The fraudulent address matched the first five and last four characters of the intended destination, differing only in the middle portion—exactly the segment most wallets hide behind ellipses.

This visual similarity allowed the attacker to exploit common user behavior, where traders confirm only the beginning and end of an address rather than the full string.

After receiving the funds, the attacker quickly converted the stolen USDT into DAI, then swapped it for approximately 16,690 ETH. The ETH was later deposited into Tornado Cash, a privacy protocol frequently used to obscure transaction trails. The victim subsequently offered a $1 million on-chain bounty in an attempt to recover the funds.

CZ’s Proposal to Stop Address Poisoning

In response to the incident, Changpeng Zhao proposed three industry-wide countermeasures designed to reduce address poisoning risk across wallets and platforms.

First, Zhao called for automatic detection of suspected poison addresses within wallets. These systems would flag addresses that closely resemble previously used destinations and warn users before transactions are signed.

Second, he suggested real-time sharing of blacklisted scam addresses across the industry. A coordinated database could allow wallets and exchanges to instantly recognize known malicious addresses and alert users.

Third, Zhao recommended filtering spam transactions from wallet histories. Since attackers often seed wallet activity with fake transactions to create misleading address records, hiding or isolating these entries could significantly reduce the effectiveness of poisoning attempts.

Binance Wallet already implements warnings for suspected poison addresses, but Zhao emphasized that isolated solutions are not enough. Address poisoning, he argued, requires a collective response across the crypto ecosystem.

Why Address Poisoning Is a Growing Threat

The incident underscores a broader trend in crypto-related crime. Phishing attacks were the most costly category of crypto theft in 2024, according to blockchain security firm CertiK. Attackers stole more than $1 billion across 296 phishing incidents that year alone.

In 2025, address poisoning accounted for over 10% of wallet drain incidents, reflecting both its effectiveness and ease of execution. The technique does not rely on smart contract vulnerabilities or malware, making it harder to detect with traditional security tools.

One notable case in May 2024 involved a victim who lost $68 million worth of wrapped Bitcoin through address poisoning. In that instance, the attacker eventually returned the funds after pressure from investigators, but such outcomes remain rare.

The Bigger Picture for Crypto Security

Total cryptocurrency theft reached an estimated $3.4 billion in 2025, reinforcing the urgency of improving user-level protections. As self-custody adoption grows, so does the responsibility placed on individuals to verify transactions accurately.

Address poisoning highlights a fundamental usability issue in crypto wallets: human-readable shortcuts can create dangerous blind spots. Without better safeguards, even cautious users can make irreversible mistakes in seconds.

Changpeng Zhao’s call for industry-wide standards reflects a growing consensus that security must evolve alongside adoption. Preventing address poisoning will likely depend not only on better tools, but on collaboration across wallets, exchanges, and blockchain infrastructure providers.

As crypto continues to move toward mainstream usage, reducing preventable losses may prove just as important as advancing new technologies.

A security incident involving the Trust Wallet browser extension has resulted in the loss of nearly $6 million worth of cryptocurrency, triggering concern across the crypto community during the holiday period. The breach highlights ongoing risks tied to browser-based wallets and the importance of rapid updates when vulnerabilities emerge.

According to Trust Wallet, the issue is limited to version 2.68 of its browser extension. Users of the Trust Wallet mobile application and those running other extension versions are not affected.

What happened with the Trust Wallet hack?

The vulnerability was first identified on December 24, when abnormal wallet activity began appearing on-chain. By December 25, blockchain analysts observed funds being drained from multiple wallets operating on Bitcoin, Ethereum, and Solana networks.

Independent investigator ZachXBT reported receiving messages from hundreds of users whose balances dropped suddenly without any outgoing transactions initiated by them. Community researchers later identified suspicious code within version 2.68 of the extension. The code allegedly redirected sensitive wallet data to a fake external website, giving attackers unauthorized access to user funds.

On-chain analysis suggests the stolen funds were routed through numerous addresses, making the total scope difficult to track precisely. Current estimates place losses at a minimum of $6 million.

Trust Wallet confirms extension vulnerability

Trust Wallet has acknowledged the incident and confirmed that only the 2.68 browser extension was compromised. The company instructed users to immediately stop using that version and upgrade to version 2.69, which it says resolves the issue.

The wallet provider stated that its security and support teams are actively investigating the breach and reaching out to affected users. While Trust Wallet has not yet confirmed whether compensation will be offered, it says impacted users are being guided through recovery and reporting steps.

What users should do immediately

Anyone who used the Trust Wallet browser extension is advised to take action without delay:

First, do not open the Trust Wallet extension on desktop devices if it is still enabled. This reduces the risk of further exposure.

Second, disable the extension immediately via the browser’s extensions settings.

Third, update only to version 2.69 and ensure the update is downloaded exclusively from the official Chrome Web Store. Users should double-check the version number after installation.

Finally, contact Trust Wallet support if any funds are missing. Providing transaction history and wallet details may help ongoing investigations.

Why this incident matters for crypto users

The Trust Wallet hack underscores the unique risks associated with browser extensions. Unlike hardware wallets or isolated mobile environments, browser-based wallets operate in a space frequently targeted by malicious code injections, phishing scripts, and supply-chain attacks.

Even well-established wallet providers can be exposed if a compromised update slips through. This incident reinforces the need for users to monitor wallet updates closely, limit hot wallet balances, and consider additional security measures for long-term holdings.

As investigations continue, Trust Wallet has stated it will release further updates. For now, the breach serves as a reminder that security hygiene — including timely updates and cautious extension use — remains critical in the crypto ecosystem.

Hong Kong is moving decisively to redefine its role in the global digital asset economy. By 2026, the city plans to introduce a comprehensive licensing framework for cryptocurrency trading and custody services, signaling a clear commitment to regulated growth rather than fragmented oversight.

The initiative is being led jointly by Hong Kong’s Financial Services and the Treasury Bureau (FSTB) and the Securities and Futures Commission (SFC). Draft legislative proposals are now advancing after regulators reviewed more than 190 public submissions gathered during a two-month consultation period. The upcoming framework is expected to align closely with the Anti-Money Laundering and Counter-Terrorist Financing Ordinance (AMLO), bringing crypto market supervision closer to standards already applied in traditional securities markets.

A Unified Regulatory Vision for 2026

At the heart of Hong Kong’s 2026 crypto agenda is consolidation. Regulators aim to bring cryptocurrency trading platforms and custody providers under a single, coherent licensing regime. This approach mirrors the structure used for licensed securities brokers, offering clearer expectations around governance, compliance, and operational controls.

Custody regulation is a central focus. The proposed framework prioritizes the safeguarding of private keys, segregation of client assets, and strict controls over asset handling. On the trading side, regulators plan to clearly define who is permitted to act as a crypto broker, under what conditions, and with which compliance obligations. Together, these measures form a key pillar of the SFC’s ASPIRe roadmap, which seeks to expand access to crypto markets while strengthening investor protection.

The SFC is also broadening its scope beyond exchanges. A parallel consultation is underway to extend oversight to cryptocurrency advisors and asset managers. Under the guiding principle of “same business, same risk, same rule,” the regulator intends to apply standards comparable to those governing securities advisory and portfolio management services. Feedback on this proposal is open until January 23.

Building a Regulated Crypto Hub in Asia

Hong Kong’s regulatory push is part of a broader ambition to establish itself as a leading crypto hub in Asia. Rather than adopting a permissive or hands-off approach, the city is positioning regulation as a competitive advantage—one designed to attract institutional capital, global firms, and long-term builders.

This strategy places Hong Kong in direct competition with other financial centers such as Singapore, while standing in sharp contrast to mainland China’s continued restrictions on cryptocurrency activity. Over the past year, regulators have steadily laid the groundwork for this transition.

In February, the SFC announced new licensing requirements for over-the-counter crypto trading. This was followed by reviews of derivatives and margin trading involving digital assets. By April, regulators had approved staking services for licensed exchanges and funds, subject to strict asset control and disclosure requirements. Spot crypto exchange-traded funds have also been trading locally since 2024, further integrating digital assets into the regulated financial system.

Why This Matters for the Crypto Market

Hong Kong’s approach reflects a growing recognition that institutional participation requires clarity, accountability, and auditability. By aligning crypto market infrastructure with standards familiar to traditional finance, the city is attempting to bridge the gap between innovation and risk management.

The proposed framework does more than regulate individual activities. It seeks to create an integrated pathway where trading, custody, advisory services, and asset management operate under a unified regulatory architecture. For market participants, this reduces uncertainty. For investors, it strengthens confidence. And for Hong Kong, it reinforces the city’s ambition to serve as a gateway between global capital and the digital asset economy.

As the 2026 timeline approaches, Hong Kong’s regulatory experiment will be closely watched. Its success—or failure—could influence how other financial centers approach crypto regulation, particularly as institutional demand continues to rise and global standards begin to converge.
