Threshold Network says its tBTC bridge has resumed onchain operations after a security pause that began on October 30, while the user-facing app remains paused, according to The Defiant and Cointelegraph. Cointelegraph described the restart as partial and said the app will not accept new deposits, minting or redemptions until enough node operators are back online. Threshold has not announced a restart date, and requests submitted before the shutdown should be processed as operators return.
The pause came while operators patched a critical Linux kernel vulnerability that could let remote attackers run code on unpatched servers, Cointelegraph reported. Threshold said it found no evidence the flaw was exploited against tBTC nodes and saw no unauthorized Bitcoin transfers or minting. Earlier Threshold updates cited by The Defiant said every operator had either patched or taken nodes offline.
On backing, Cointelegraph cited about 4,320 BTC in bridge wallets against roughly 4,185 tBTC in circulation. The Defiant separately counted 4,320.33 BTC in six large wallets in an earlier check, against 4,185.16 tBTC shown on Etherscan.
The pause also hit DeFi. Aave froze its Ethereum Core tBTC reserve on October 31, which The Defiant now puts at $119.9 million. The freeze blocks new deposits and new borrowing against tBTC, while repayments and withdrawals continue. Aave risk provider LlamaRisk said it will propose restoring the reserve once Threshold’s operations return to normal. Both the timeline for the app and for the reserve remain unconfirmed.
