# LlamaRisk proposes refreshing 27 Aave CAPO oracle snapshots

> The proposed cap reference points move to readings from September 28–29. LlamaRisk says the old snapshots and the growing gap between cap and current ratio could let collateral be overpriced during an inflation attack.

## What happened

LlamaRisk submitted a Direct-to-AIP proposal to refresh the CAPO snapshot ratios and timestamps on named Aave v3 adapters for yield-bearing collateral.

## What changed

The proposed cap reference points move to readings from September 28–29. LlamaRisk says the old snapshots and the growing gap between cap and current ratio could let collateral be overpriced during an inflation attack.

## What did not change

This is a proposal, and the oracle update has not executed. LlamaRisk modeled an attack; no inflation attack, collateral loss or bad debt has occurred.

## Confirmed

- The proposal lists new snapshotRatio and snapshotTimestamp values for 27 adapter configurations.
- The proposal covers assets including wstETH, tETH, sUSDe, weETH, cbETH, rETH, syrupUSDT, osETH, sAVAX and ezETH on named markets.
- The proposed Optimism wstETH snapshot timestamp moves from Feb. 15, 2024, to Sept. 29, 2026.
- The proposal describes selection rules meant to pass the _setCapParameters checks.

## Still open

- We do not know when the AIP will be created, how the vote will go, when it will execute or the final adapter parameters.
- Nobody outside LlamaRisk has reproduced its gap measurements or modeled losses.
- We do not know whether more adapters need a refresh before execution.

## What it means for an advisor

- Check snapshot age, cap headroom and the adapters behind any Aave v3 collateral a client might use.
- Check the vote, the execution and the live parameters before treating the modeled risk as fixed.
