Polkadot Confirms Exploit on Hyperbridge's Ethereum Gateway Contract

Polkadot confirmed on Monday, April 13, that an exploit occurred on Hyperbridge's Ethereum gateway contract. The Polkadot team stated that native DOT and the broader Polkadot ecosystem remain fully secure and unaffected by the incident.

Hyperbridge also confirmed the exploit in an X post this morning and said that it has paused bridging “while the team contains the issue.”

CertiK first flagged the exploit, reporting that the attacker had minted 1 billion DOT, worth about $1.17 billion at current prices, but only successfully cashed out about $237K.
