# Threshold Restarts tBTC Bridge Following Security Pause as Aave Holds Freeze

Independent node operators are reconnecting after a Linux patch, leaving an Aave reserve holding roughly $120 million in tBTC frozen to new deposits.

## At a glance

- **What happened:** Threshold Network initiated the restart of its tBTC bridge following a nine-day security maintenance pause triggered by a Linux kernel vulnerability.
- **Why it matters:** The bridge is clearing pending transactions with intact reserves, but an Aave pool holding about $120 million in tBTC remains blocked from new deposits.
- **Who is affected:** Threshold tBTC bridge users, node operators, and Aave tBTC depositors.
- **What's next:** LlamaRisk will propose restoring the Aave reserve once Threshold confirms normal operational parameters.

## Key points

- Threshold began restarting its tBTC bridge after an operational pause dating back to Oct. 30 [1].
- About $120 million in tBTC remains frozen to new deposits and collateral borrowing within Aave [1].
- Backing reserves hold roughly 4,320 BTC against 4,185 circulating tBTC, with no detected exploits [1].

## Editorial remark

- **Context:** The bridge was paused on Oct. 30 to remediate a critical Linux kernel flaw on operator nodes, leading Aave to freeze the reserve on Oct. 31 as a safeguard against redemption risks.
- **Impact:** tBTC holders cannot yet initiate new mints or redemptions, while Aave users holding roughly $120 million in tBTC cannot supply more collateral or expand borrowing capacity.
- **Watch:** LlamaRisk's upcoming governance proposal to unfreeze the Aave tBTC reserve once full node connectivity is restored.

The Threshold Network initiated the restart of its tBTC bridge on Sunday after a nine-day security shutdown, according to an announcement from the protocol [1]. Despite the bridge's onchain recovery, an Aave reserve holding approximately $120 million worth of the wrapped asset remains restricted from accepting new deposits or granting additional borrowing power [1].

Threshold halted bridge activity on Oct. 30 after identifying a critical Linux kernel vulnerability capable of granting remote attackers arbitrary code execution on unpatched hardware [1]. The network reported that independent node operators, who jointly validate Bitcoin transfers and facilitate minting and redemption cycles, are reconnecting after applying security patches [1]. The protocol stated that it identified no evidence that the vulnerability was exploited against its nodes, nor were any unauthorized token mints or Bitcoin transfers detected [1]. Backing reserves stand at roughly 4,320 $BTC against an active circulation of approximately 4,185 tBTC [1].

## Unfreezing Conditions on Aave

While the bridge processes backlogged transactions submitted prior to the Oct. 30 suspension, the front-end application will not permit new minting, deposits, or redemptions until a sufficient threshold of operators re-establishes connectivity [1]. Threshold has not yet set a definitive date for full operational capability [1].

In response to the initial stoppage, lending protocol $AAVE [froze its tBTC reserve](https://basisdesk.news/news/aave-freezes-tbtc-reserve-threshold-pause) on Ethereum Core on Oct. 31 to curb protocol exposure while underlying redemptions were paused [1]. Existing depositors may continue withdrawing assets and servicing outstanding debt [1]. Risk management firm LlamaRisk stated that it plans to submit a governance proposal to lift the reserve restrictions once Threshold demonstrates normalized operations [1].
