After shutting down for nine days due to a security issue, Threshold Network’s tBTC bridge has resumed on-chain activity, but the reserve on Aave containing about $120 million worth of tBTC remains frozen. The bridge will allow new deposits, minting, and redemptions only after a sufficient number of nodes reconnect. Threshold suspended the bridge on October 30 because a critical vulnerability in the Linux kernel could allow remote attackers to run code on unpatched servers. Threshold said there is no evidence the vulnerability was ever used to attack tBTC nodes. Aave still allows users to withdraw funds and repay loans, but prohibits new tBTC deposits and does not allow the token to provide additional borrowing capacity. Risk service provider LlamaRisk said it would propose reopening the reserve on Aave once Threshold resumes normal operations.
