Threshold Network’s tBTC bridge began resuming onchain operations after a nine-day security pause, but the restart did not yet restore full user access. An Aave reserve holding about $120 million in tBTC also remained frozen to new deposits and additional borrowing power.

Network restart was not a full reopening
Threshold said on Sunday that security-patched node operators were reconnecting to the bridge’s underlying network. These independent 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 did not announce a date for reopening those functions.
The distinction matters for access: resumed onchain operations did not mean users could immediately initiate new bridge transactions.
Security pause and Aave restrictions
Threshold halted the bridge on October 30 while operators addressed a critical Linux kernel vulnerability that could allow remote attackers to execute code on unpatched servers. The project said it found no evidence that the vulnerability had been exploited against tBTC nodes.
Aave froze its tBTC reserve on Ethereum Core on October 31 to prevent additional exposure while redemptions were unavailable. The freeze blocked new tBTC deposits and prevented the token from adding borrowing power, while 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 was a conditional proposal, not an announced reopening.
Reported backing, not a measure of adoption
Threshold reported roughly 4,320 BTC in bridge wallets, compared with about 4,185 tBTC in circulation, and said it had detected no unauthorized Bitcoin transfers or token minting.
Those figures describe reported bridge holdings and token supply at the time of the report. They do not establish user growth, retention or renewed demand. The immediate issue was operational availability: enough operators needed to return before the app could reopen, while Aave’s restrictions remained in place.
