## What happened

Aave's ARFC vote approved advancing tBTC onboarding for the Base v3 instance.

## What changed

The proposal advanced to final AIP preparation with recommended collateral, borrowing, cap, liquidation, and BTC/USD oracle settings.

## What did not change

ARFC approval did not add the reserve or make tBTC available on Aave Base; final AIP approval and execution remained necessary.

## Confirmed

- The ARFC passed on August 25, 2025, with quorum and YAE as the winning option.
- The proposed Base tBTC contract is 0x236aa50979D5f3De3Bd1Eeb40E81137F22ab794b.
- Recommended parameters include a 130 tBTC supply cap, 13 tBTC borrow cap, 73% LTV, and 78% liquidation threshold.
- The next stated step was publication of an AIP.

## Still open

- Final AIP result and execution were not established for this event.
- Final oracle configuration and live reserve parameters require post-execution reconciliation.

## What it means for an advisor

- Monitor the final AIP and verify live parameters before considering tBTC-on-Base exposure.
- Review Threshold minting, Wormhole-related Base components, secondary liquidity, and BTC/USD pricing dependencies.
- Do not infer that ARFC approval constitutes product approval for clients.
