$2.5M Hyperbridge Hack Triggers System-Wide Rebuild Amid DeFi Weakness

Hyperbridge, a cross-chain interoperability protocol, recently faced a major exploit on April 13, resulting in the minting of approximately 1 billion fake DOT tokens. The attack occurred when hackers found a weakness in the Token Gateway smart contract on Ethereum, allowing them to trick the system and create fake bridged tokens that were then swapped for real crypto.

The initial loss was estimated at around $237,000, but further checks revealed the damage to be significantly higher, reaching approximately $2.5 million after accounting for incentive pool damage across various chains.

Rather than simply patching the issue, Hyperbridge's team decided to rebuild large parts of their system, removing centralized controls and shifting towards a more permissionless design. This new approach allows anyone to run key proof checks, reducing reliance on a single group and increasing security.
