Hyperbridge Says Attacker Forged Proofs and Minted 1 Billion Bridged DOT Tokens

Hyperbridge said an attacker forged proofs, took control of the bridged DOT contract on Ethereum and minted 1 billion bridged DOT tokens in what the project described as a security incident. The protocol published the update in its official security notice.

The project’s statement centers on a failure in the cross-chain verification path rather than a routine token issuance event. According to the update, the attacker was able to bypass the contract’s proof checks and create a large amount of bridged DOT on Ethereum. Hyperbridge did not frame the event as a planned release or normal network operation.

Bridged assets depend on the security of the verification process that links one chain to another. In this case, Hyperbridge said the attacker used forged proofs to interfere with that process and mint the tokens. The post does not, by itself, establish any broader impact beyond the contract and tokens involved in the incident.

What Hyperbridge disclosed about the attack path

Hyperbridge’s update ties the incident to the bridged DOT contract on Ethereum. The project said the attacker gained control of that contract after forging proofs, then minted the 1 billion tokens. The statement gives a clear account of the mechanism the project believes was abused, but it does not add further detail in the headline-level description about any wider spread across other contracts or chains.

Because the update is a security notice, the main confirmed point for readers is the mint itself and the method Hyperbridge says was used. Any additional interpretation about market effects or broader protocol exposure would need further confirmation from the project or other public reporting.
