Threshold Network’s tBTC bridge has resumed onchain operations following a nine-day security pause, though an Aave reserve holding approximately $120 million in the token remains frozen to new deposits and borrowing.
The partial restart allows the underlying network to process pending requests as security-patched node operators reconnect. However, the bridge application will not accept new deposits, minting or redemptions until a sufficient number of nodes are online to ensure secure operation.
Network status and backlog
On Sunday, Threshold stated that the bridge’s underlying network was restarting. The project indicated that requests submitted before the shutdown are expected to be processed as more operators return, but it did not announce a specific date for the restoration of full functionality.
Threshold initially halted the bridge on Oct. 30 while operators addressed a critical Linux kernel vulnerability. The project stated it found no evidence the flaw was exploited against tBTC nodes. Threshold reported roughly 4,320 BTC remains in bridge wallets against about 4,185 tBTC in circulation, with no unauthorized Bitcoin transfers or token minting detected.
Aave maintains restrictions
Aave froze its tBTC reserve on Ethereum Core on Oct. 31 to prevent additional exposure while redemptions were unavailable. The restriction stops new tBTC deposits and prevents the token from adding borrowing power, although existing users can still withdraw assets and repay loans.
LlamaRisk, the risk provider for Aave, said it would propose restoring the reserve after Threshold’s operations return to normal.
