Threshold Network has partially restarted its tBTC bridge after a nine-day security pause, though a $120 million reserve on Aave remains frozen. The bridge, which facilitates Bitcoin transfers to Ethereum, was halted on Oct. 30 due to a critical Linux kernel vulnerability that could allow remote code execution on unpatched servers. Threshold confirmed no evidence of exploitation but paused operations to apply security patches.
On Sunday, Threshold announced the bridge’s underlying network was restarting as patched node operators reconnected. These operators authorize Bitcoin movements and process deposits and redemptions. While the bridge is resuming operations, it will not accept new deposits, minting, or redemptions until enough nodes are online. Threshold did not provide a specific restart date for full functionality.
Aave froze its tBTC reserve on Oct. 31 to prevent additional exposure while redemptions were unavailable. The restriction stops new tBTC deposits and the token from adding borrowing power, though existing users can still withdraw and repay loans. Threshold reported that roughly 4,320 BTC remains in bridge wallets against about 4,185 tBTC in circulation, with no unauthorized transfers or minting detected.
LlamaRisk, Aave’s risk provider, said it would propose restoring the reserve after Threshold’s operations return to normal. The partial resumption of the tBTC bridge marks a step toward stabilizing the network after the security pause.
