Holograph Protocol
Holograph Protocol operated as an omnichain tokenization protocol intended to preserve token identity across EVM chains. It is included because an attacker abused the Holograph Operator contract in June 2024 to mint one billion unauthorized HLG tokens, prompting a protocol lock, exchange-account freezes, a burn plan, and an investigation involving Halborn and law enforcement.
