Threshold Network has restarted onchain operations for its tBTC bridge after a nine-day security pause, though key user functions are still offline. The restart began after node operators running patched software started reconnecting to the network, according to an update published Sunday.

The bridge is not yet fully open. Threshold said it will continue blocking new deposits, minting and redemptions until a sufficient number of patched nodes are back online. At the same time, Aave’s Ethereum Core market continues to restrict its tBTC reserve, which holds about $120 million worth of the token.

Bridge resumes in limited mode

Threshold said the bridge’s underlying network is coming back into service as operators reconnect after applying security fixes. The protocol also said requests that were submitted before the shutdown should begin to move through as more operators return to normal operation.

Even with onchain activity restarting, the application remains in a limited state. Threshold did not give a date for restoring full functionality and said it would keep new deposits, minting and redemption requests disabled until enough patched operators are online.

Aave reserve remains under restrictions

Aave froze its tBTC reserve on Ethereum Core on Oct. 31, a step taken to avoid increasing exposure while redemptions through the bridge were unavailable. The reserve contains roughly $120 million in tBTC.

The current limits do not fully lock existing users in place. New tBTC deposits are blocked and the asset cannot be used to increase borrowing power, but users who already have positions can still withdraw their tBTC and repay loans.

Collateral and supply figures unchanged

Threshold said there are about 4,320 BTC in the bridge wallets, compared with roughly 4,185 tBTC in circulation. The network added that it had detected no unauthorized Bitcoin transfers and no unauthorized token minting during the incident.

Those figures are central to the market’s assessment of the bridge because they speak to whether the wrapped asset remains backed while service is disrupted. Threshold’s latest statement did not report any loss of collateral, but full normal operations have not yet resumed.

What happens next

The next confirmed step is a broader return of patched node operators, which Threshold says is required before it can reopen deposits, minting and redemptions. The protocol has not published a target date for that milestone.

On the lending side, Aave risk provider LlamaRisk said it would put forward a proposal to restore the Ethereum Core tBTC reserve once Threshold’s operations are back to normal. Until then, the reserve remains only partially available, with withdrawals and loan repayments still functioning.
