## What happened

Aave's guardian multisig froze Ethereum Core tBTC on October 31 at 10:01 UTC, according to LlamaRisk.

## What changed

Aave stopped accepting new tBTC deposits and additional borrowing power from tBTC following Threshold's minting and redemption pause.

## What did not change

Users can still repay and withdraw, and liquidators can continue liquidations. Aave kept the existing liquidation threshold.

## Confirmed

- LlamaRisk reported Threshold's precautionary minting and redemption pause on October 31.
- LlamaRisk confirmed that Aave had already frozen its Base and Arbitrum tBTC reserves during earlier deprecations.

## Still open

- Threshold's full backing claim remains unverified.
- LlamaRisk did not establish when Threshold would resume minting and redemption.

## What it means for an advisor

- Ketju should review the Aave memo's tBTC collateral restrictions and redemption dependencies.
- Borrowers cannot add tBTC to improve their health factors while the freeze remains effective.
