Threshold has restarted onchain operations for tBTC after a 9-day security pause, but this is a partial restart, not a return to normal bridge activity. Node operators are reconnecting after applying security patches for a critical Linux kernel vulnerability; the bridge was halted on October 30.
The usual Bitcoin-to-tBTC flows remain unavailable. New Bitcoin deposits are paused, new tBTC minting is paused, and redemptions are still off. So the network is coming back online, but users still cannot move through the bridge in either direction.
That limitation is keeping Aave’s tBTC reserve, worth about $120 million, frozen to new deposits and new borrowing. Existing borrowers can still repay, and suppliers can withdraw, so current positions can be unwound. But the reserve cannot support fresh lending activity while tBTC access remains restricted.
Threshold has described the halt as precautionary and tied it to security patching. The open question is operational restoration, not whether bridge activity has fully resumed. LlamaRisk is expected to propose restoring Aave’s reserve once bridge operations return to normal. The checkpoint is whether Threshold brings deposits, minting and redemptions back together; until then, the restart has not cleared the restriction that matters for Aave users.
