Threshold Network’s tBTC bridge began resuming onchain operations after a nine-day security pause, but the restart did not immediately restore access to new bridge requests or remove Aave’s restrictions on the token.
As reported on Nov. 9, 2026, at 12:03:08 UTC+8, an Aave reserve holding about $120 million in tBTC remained frozen to new deposits and additional borrowing power from the token.
Network recovery did not mean full bridge access
Threshold said on Sunday that the bridge’s underlying network was restarting as independent node operators reconnected after applying security patches. Those operators collectively authorize Bitcoin movements and process deposits and redemptions.
Requests submitted before the shutdown were expected to be processed as more operators returned. However, the app would not accept new deposits, minting or redemptions until enough nodes were online. Threshold had not announced a date for reopening those functions.
The bridge was initially halted on Oct. 30 while operators addressed a critical Linux kernel vulnerability that could allow remote attackers to execute code on unpatched servers. Threshold said it found no evidence that the vulnerability had been exploited against tBTC nodes.
Aave kept limits on new exposure
Aave froze its tBTC reserve on Ethereum Core on Oct. 31 to prevent additional exposure while bridge redemptions were unavailable.
The restriction blocked new tBTC deposits and prevented the token from adding borrowing power. Existing users could still withdraw and repay loans.
Aave risk provider LlamaRisk said it would propose restoring the reserve after Threshold’s operations returned to normal. That statement was a planned proposal, not confirmation that the restrictions had been lifted.
Reported backing and circulating supply
Threshold reported roughly 4,320 BTC in bridge wallets, compared with about 4,185 tBTC in circulation. It also said no unauthorized Bitcoin transfers or token minting had been detected.
Those reported balances were distinct from operational availability: the network’s gradual restart did not yet mean users could submit new minting or redemption requests, or use new tBTC deposits to increase borrowing power on Aave.
