Aave considers onboarding USSD to its Sonic market

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.
