## What happened

An Aave DAO temperature check proposed onboarding USSD as a supply and borrowing reserve on the Aave V3 Sonic instance.

## What changed

If governance advances and executes the proposal, Aave Sonic would gain a new stablecoin exposure whose stated reserve and redemption stack includes cross-chain minting, third-party custodians, and tokenized Treasury products including WTGXX.

## What did not change

No ARFC, AIP, execution, reserve activation, risk parameters, caps, collateral settings, or independently verified reserve state is established by this temperature check.

## Confirmed

- The proposal identifies USSD's Sonic token address.
- The proposal describes USSD as redeemable through CCTP-supported chains and interoperable through LayerZero.
- WTGXX is among the tokenized Treasury instruments the proposal says can support USSD.
- Risk parameters were deferred to later service-provider review.
- The stated process requires further ARFC and AIP stages before enforcement.

## Still open

- The temperature-check vote outcome.
- Independent verification of USSD reserves, custodians, redemption rights, and legal structure.
- Whether WTGXX or another reserve asset would actually back circulating USSD used on Aave.
- Final oracle design, caps, collateral status, liquidation parameters, and bridge assumptions.
- Any ARFC, AIP, deployment address, and executed reserve state.

## What it means for an advisor

- Monitor the governance sequence without treating USSD as an approved or live Aave reserve.
- If the proposal advances, review USSD's reserve attestations, redemption waterfall, bridge dependencies, oracle design, and WTGXX linkage before changing the Aave or WisdomTree memos.
