ChainCatcher report: RetoSwap disclosed on X that at 2:02 AM Beijing time today, the team received a report that the Haveno transaction protocol was under attack. The team immediately set the minimum client version to 2.0 using the filter function, suspended trading, and blocked the attacker’s onion address. RetoSwap stated that its team was not directly attacked and that the vulnerability exists at the Haveno protocol level. The 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 RetoSwap had been compromised of approximately $2.7 million due to a vulnerability in the Haveno protocol.

Summary
RetoSwap upgraded its client version and suspended trading after a Haveno protocol attack was reported at 2:02 AM Beijing time. The team raised the minimum client requirement to version 2.0, halted trading, and blocked the attacker’s onion address. The incident stems from a protocol-level vulnerability, not a compromise by the RetoSwap team. Losses appear limited to large cryptocurrency orders, with fiat traders unaffected. The Fear & Greed Index may react as trading volume declines during the suspension. The team is evaluating recovery options and will resume trading once the protocol flaw is resolved. This follows a $2.7 million theft exploiting a Haveno vulnerability on May 21.
