## What happened

Aave Labs proposed listing Open USD on Ethereum V3 Core and V4 Core as a supply and borrow asset.

## What changed

The concrete listing proposal adds an issuer-controlled stablecoin to the research pipeline. The ARFC describes upgrade, pause, freeze, seizure, and transfer-policy powers that require listing diligence.

## What did not change

No listing authorization or execution is established. Collateral use is disabled in the proposal, and future collateral enablement would require separate governance.

## Confirmed

- The ARFC proposes supply and borrowing access with collateral disabled.
- The proposal describes Bridge Building Inc as issuer and Open Standard as program company.
- The ARFC describes privileged issuer functions and an external policy registry.
- Final parameters await risk recommendations and production Chainlink feeds.
- Snapshot and an AIP are described as subsequent steps.

## Still open

- Final caps, reserve factor, interest-rate model, and oracle configuration.
- Independent verification of the deployed token's authority and audit mapping.
- Approval and execution status.
- Operational redemption limits and available reserve attestations.

## What it means for an advisor

- Monitor the listing and require a complete issuer, control, reserve, and redemption review before extending the Aave memo's supported exposure perimeter.
- Preserve the distinction between a supply-and-borrow listing and collateral approval.
