Aave opens final governance for tBTC collateral on Arbitrum

What happened

Aave opened an on-chain proposal to add tBTC as collateral on its Arbitrum v3 instance.

What changed

If executed, tBTC would become non-borrowable collateral with a 50 tBTC supply cap, 73% LTV, 78% liquidation threshold, and Chainlink BTC/USD pricing.

What did not change

The proposal record does not by itself confirm execution or establish that tBTC was available as collateral on August 20.

Confirmed

• The proposed Arbitrum tBTC contract is 0x6c84a8f1c29108f47a79964b5fe888d4f4d0de40.
• The proposed supply cap is 50 tBTC and the borrow cap is 25, while borrowing is described as disabled in the operative configuration.
• The proposed LTV and liquidation threshold are 73% and 78%.
• The candidate links Aave Governance proposal 360.

Still open

• Final vote result and execution timing require operative on-chain confirmation.
• The final live reserve configuration and oracle address must be reconciled after execution.

What it means for an advisor

• Monitor final execution before treating tBTC on Arbitrum as an available Aave collateral market.
• Review wrapped-Bitcoin minting, bridge, oracle, liquidity, and liquidation dependencies introduced by the listing.
• Confirm that the final borrow-enabled flag and borrow cap are internally consistent.
