Haven Protocol suffers an attack due to a vulnerability in "range proof verification"

ChainCatcher message, Haven Protocol has been attacked due to a vulnerability in the "range proof verification." The vulnerability allows hackers to illegally mint XHV without detection. The amount of XHV reported by exchanges exceeds 500 million, while audit data shows the current supply is only 263 million, indicating that the excess may have been generated through the vulnerability.

The team has confirmed that the issue lies in the "range proof verification" feature introduced after the Haven 3.2 reconstruction based on Monero, and the team has advised exchanges to halt trading on all trading pairs.
