## What happened

An official Aave DAO temperature check proposed adding USSD as a supplied and borrowable stablecoin in the Aave v3 Sonic instance.

## What changed

The proposal placed USSD and its reserve, minting, redemption, custody, and interoperability dependencies into Aave governance review. It did not yet change live Aave parameters.

## What did not change

No ARFC, AIP, execution, live reserve, collateral status, caps, LTV, liquidation threshold, or oracle configuration was established by this temperature check.

## Confirmed

- The proposal targeted the Aave v3 Sonic instance.
- It proposed enabling users to supply USSD and use it as a borrowing asset.
- The proposal described USSD as relying on tokenized Treasury reserves, institutional custodians, and cross-chain minting infrastructure.
- Risk parameters were deferred to later service-provider review and an ARFC.

## Still open

- The temperature-check vote outcome and any subsequent ARFC or AIP were not established by the candidate record.
- Final reserve parameters, oracle design, caps, collateral eligibility, and liquidation settings were unspecified.
- The reserve, redemption, custody, and interoperability claims had not been independently underwritten for Ketju.
- No live execution was confirmed.

## What it means for an advisor

- Monitor the proposal through ARFC and on-chain execution before treating USSD as part of any approved Aave v3 market.
- If the listing advances, review the Sonic instance and USSD as a distinct exposure with issuer, reserve, custodian, bridge, oracle, and redemption dependencies.
- Do not infer approval from the Aave v3 protocol-level verdict.
