## What happened

A pufETH collateral-onboarding TEMP CHECK for Aave v3 Ethereum Core advanced to a Snapshot vote.

## What changed

If later approved and executed, Ethereum Core would add liquid-restaking collateral with Puffer, EigenLayer, exchange-rate, withdrawal-liquidity, slashing, and privileged-control dependencies.

## What did not change

The TEMP CHECK contained no final risk parameters and did not authorize or execute an asset listing. Existing collateral, oracle, liquidation, and borrowing configurations were unchanged.

## Confirmed

- The target market is Aave v3 Ethereum Core.
- The proposal identifies pufETH as a proposed collateral asset.
- The official forum states that the TEMP CHECK advanced to Snapshot on January 29.
- An Aave-funded risk contributor opposed onboarding at that stage, citing declining supply, reduced liquidity, pricing complexity, double-slashing exposure, and no active bug bounty.

## Still open

- The TEMP CHECK result and whether the proposal advances through ARFC and AIP stages.
- Final oracle design, collateral factors, liquidation settings, caps, and e-mode treatment.
- Whether pufETH liquidity, withdrawals, incentives, and security controls support the proposed risk parameters.

## What it means for an advisor

- Monitor the governance process and require a position-specific collateral and dependency review before treating pufETH as acceptable.
- Do not change the existing Aave approval or describe pufETH as supported based on the TEMP CHECK.
