RetoSwap Halts Trading After Haveno Protocol Exploit; About 7,000 XMR Reportedly Stolen

RetoSwap said on May 21 (UTC+8) that Haveno's trading protocol—the upstream open-source project it relies on—was compromised by a hacker. The Tor-based peer-to-peer multisignature DEX has since blocked the attacker's onion address and paused trading by restricting client versions, adding that RetoSwap itself was not directly targeted. RetoSwap said the incident mainly affected large-value crypto transactions, while fiat-side traders were not impacted. The team is assessing ways to help affected users recover funds. PeckShield monitoring estimated losses at roughly 7,000 XMR, or about $2.7 million. Foresight News noted that RetoSwap is a fork of Haveno.
