Threshold Network's tBTC Bridge Resumes Operations; $120 Million Aave Reserve Remains Frozen

Threshold Network Resumes tBTC Bridge Operations

Threshold Network has restarted its tBTC bridge operations after a nine-day hiatus, initiated on October 30 due to a significant vulnerability in the Linux kernel which posed risks of remote code execution for unprotected servers. This measure was taken to enhance security before resuming transactions.

While the bridge is back in action, it is important to note that an Aave reserve, which contains approximately $120 million worth of tBTC, is currently barred from new deposits and lending activities.

Security Measures and Node Operations

On Sunday, Threshold announced that the network's underlying nodes—operated by independent parties responsible for authorizing Bitcoin transfers and managing deposit and redemption requests—were beginning to come back online with necessary security patches. However, until a sufficient number of nodes are re-established, the application will not accommodate any new deposits, minting, or redemptions. The exact date for when full services will recommence has not been disclosed yet.

Initially, the tBTC bridge was paused as a precaution against the aforementioned vulnerability, with Threshold confirming no signs of the bug being exploited. Meanwhile, Aave acted swiftly by freezing its tBTC reserve on October 31, aiming to mitigate potential risks while withdrawals were temporarily halted.

Current Status of tBTC

As it stands, roughly 4,320 Bitcoin remain secured in the bridge's wallets, contrasted with around 4,185 tBTC actively circulating in the market. No unauthorized transactions or minting of new tokens have been reported. Once normal operations resume, LlamaRisk, an Aave risk management partner, plans to recommend lifting the freeze on the tBTC reserve, allowing it to reopen for business.
