Crypto exchange HTX stakeholder Justin Sun confirmed on Monday that the exchange suffered a hack over the weekend, with losses totaling $8 million. 

In an X thread, Sun wrote that the losses have been covered by the exchange, that current user deposits are secure, and that the platform is operating normally. 

Sun also publicly offered the hacker a 5% upon the return of the remainder of funds — short of the 10% often offered to attackers — in addition to a job at the exchange.  

Tron (TRX) is close to flat on the day, down 0.83%. Per DeFiLlama, HTX (formerly Huobi) has seen nearly $10 million in outflows, with $2.73 in customer deposits on hand. 

While the hack took place on Sunday, it largely went unnoticed until security firm Cyvers Alerts posted a thread on the attack at 9:35 am ET. An hour later, Sun confirmed the attack.

An address labeled as a HTX hot wallet by Nansen sent the hacker a series of messages in both English and simplified Chinese Monday morning. 

“We have identified your true identity. Please return the funds to 0x18709E89BD403F470088aBDAcEbE86CC60dda12e. We will offer you a 5% white hat bonus. This offer is valid for 7 days, until Oct. 2, 2023. If you have not returned the funds by then, we will involve law enforcement,” reads one. 

The hack comes just a few days after Sun posted a promotional video animation in which the billionaire, while on a spaceship to what appears to be Mars, defeats a hooded figure representing a hacker “shorting crypto” with a single punch.

Sun’s LinkedIn profile lists him has a member of Huobi’s “Global Advisory Board.” Bloomberg previously reported that the TRON founder bought a 60% stake in the exchange for $1 billion, though he has publicly denied owning a majority stake. 

Multiple Huobi and Justin Sun reps declined a request for comment by press time.

ERC 8004 introduces a new trust layer for AI agents by standardizing onchain identity, reputation, and validation. As agents begin handling capital and coordinating autonomously, trust becomes the key constraint to broader adoption. The rollout mirrors the early x402 narrative, where adoption lagged the initial launch until major integrations and a viral use case pulled attention into the ecosystem. If ERC 8004 follows a similar path, downstream infrastructure tied to the standard could see outsized benefit as the narrative gains traction. The primary beneficiaries are likely to be agent frameworks and launchpads at the distribution layer, agent to agent coordination platforms that enable delegation and payments, and validation providers that offer stronger security and execution guarantees.
