- Contract Vulnerability
Incident Overview
According to reports from exchanges, the amount of XHV exceeds 500 million tokens, while audit data indicates a current supply of only 263 million tokens. The surplus is likely generated through this exploit. The team found a weakness in the "range proof validation", which was introduced after the Haven 3.2 rebase to Monero and has advised exchanges to halt trading on all pairs.
