Hyperbridge Exploit Review Bifrost integrates with @hyperbridge to provide cross-chain vToken minting and redemption services across multiple networks, including @Ethereum, @base , @arbitrum , @Optimism, and @BNBCHAIN Following the recent security incident involving Hyperbridge, the Bifrost team responded immediately and implemented a series of protective measures. Full Asset Audit All vToken reserves on Bifrost remain secure. A detailed breakdown is as follows: vDOT: Secure. However, vDOT that had been bridged to Base via Hyperbridge were exposed. The exploit only affected mirrored assets already existing on Base. No new vTokens were minted on Bifrost. vETH / vMANTA / vASTR / vPHA / vBNC: Fully secure. Total issuance remains 1:1 backed by on-chain reserves. vKSM: Not affected, as it is not integrated with Hyperbridge. Any ETH or MANTA losses are limited to Hyperbridge's own reserves and are entirely unrelated to Bifrost's vToken operations. Actions Taken Upon learning of the security incident, our team acted immediately to eliminate any risk of further exposure. The following measures have been implemented: Cross-chain channels closed. All cross-chain communication channels between Bifrost and Hyperbridge have been suspended. No messages can be transmitted in either direction until the situation is fully resolved. Mint and burn permissions revoked. Hyperbridge's authority to mint or burn any vTokens has been revoked until the situation is fully resolved. This eliminates the possibility of any further anomalous minting at the source. Cross-chain services suspended. All vToken minting and redemption services conducted via Hyperbridge have been suspended until further notice. Unaffected Services The following core functionalities remain fully operational: - All native features on Bifrost-Polkadot chain (staking, swapping, lending, etc.) - Cross-chain operations within the Polkadot ecosystem via XCM - Holding, transferring, and utilizing vTokens on the Bifrost chain Next Steps - Continue working closely with the Hyperbridge team to complete a full security assessment - Evaluate safe conditions for restoring cross-chain services - Provide timely updates to the community as progress is made Final Note The security of user funds is the highest priority for Bifrost. We acted swiftly to isolate all exposure points and have confirmed that our on-chain reserves remain sound. We understand that security incidents create uncertainty, and we want to assure the community that we are taking every necessary step to handle this responsibly.
