Huo Xing Cai Jing reports that RetoSwap disclosed on X that at 2:02 AM Beijing time today, the team received a report that the Haveno trading protocol was under attack. The team immediately used the filter function to set the minimum client version to 2.0, suspended trading, and blocked the attacker’s onion address. RetoSwap stated that its own team was not compromised—the vulnerability exists at the Haveno protocol level. Losses appear limited to large cryptocurrency orders, with fiat traders unaffected. The team is currently evaluating options to assist affected traders in recovering their funds. Trading will resume once the protocol is patched. Previously, on May 21, it was reported that due to a vulnerability in the Haveno protocol, RetoSwap suffered a theft of approximately $2.7 million.

Summary
RetoSwap upgraded its client version and suspended trading activity after an attack on the Haveno protocol was reported at 2:02 AM Beijing time. The team raised the minimum client version to 2.0, halted trading, and blocked the attacker’s onion address. The vulnerability existed at the Haveno protocol level, not within RetoSwap itself. Losses were confined to large cryptocurrency orders, with fiat traders remaining unaffected. The team is evaluating ways to support affected traders. Trading will resume once the protocol vulnerability is resolved. Earlier in 2026, a flaw in Haveno led to a $2.7 million theft from RetoSwap.
