## Summary

Aave Labs proposed adding Open USD (OUSD) to Ethereum V3 Core and V4 Core on 30 September 2026, initially for supply and borrowing without collateral use. This is a governance proposal, not a verified live listing. Open USD and Origin Dollar share a ticker but are different assets.

## What changed, and what is still pending?

The [Aave Labs ARFC](https://governance.aave.com/t/arfc-onboard-ousd-to-aave-v3-core-instance-and-aave-v4-core-hub/25735) leaves final risk parameters and oracles pending. Its path runs through community feedback, Snapshot and an onchain proposal. It identifies Bridge Building Inc as issuer and Open Standard as program operator. Issuer powers include pausing, freezing and upgrading; the listed template audits are not an OUSD-specific deployed-contract audit.

The specification also limits aggregate redemptions to 10% of outstanding supply per 24 hours, despite broader no-cap language elsewhere in the post. Readers should seek clarification of the current contractual terms. Aave Labs discloses its Open Standard partnership and says it will not receive OUSD distribution compensation or reserve income.

## Open USD is not Origin Dollar

[Open Standard’s announcement](https://joinopenstandard.com/blog/introducing-open-usd) describes a payments stablecoin whose reserve earnings principally flow to adopting partners, after management costs. That distribution model does not establish an automatic yield entitlement for every token holder. Interest from a lending position would be a separate economic relationship.

[Origin’s documentation](https://docs.originprotocol.com/yield-bearing-tokens/origin-dollar-ousd) describes Origin Dollar, also OUSD, as a USDC-backed yield-bearing token using onchain strategies and rebasing balances. These are different products with different dependencies. A symbol match in a wallet, exchange search or article is insufficient evidence that you have found the intended asset.

[Bridge’s reserve page](https://reserves.bridge.xyz/ousd), dated 1 October 2026 at 04:50 UTC when checked, links Open USD’s Ethereum token at 0x9f6F3991D525015a6F8CaF062C83b62fD3AC4436 and reports cash and Treasury reserves. This is issuer-published information, not an independent reserve audit. We do not turn its changing supply figures into a permanent headline.

## Why supply, borrowing and collateral are different permissions

Our analysis: listing is best understood as a set of permissions. Supplying an asset adds funds to a lending market. Borrowing it creates an obligation to repay that asset with the applicable interest. Enabling it as collateral is another decision, allowing its value to support debt. Readers should check each permission separately rather than relying on a single “supported” badge.

[Aave V4 documentation](https://aave.com/docs/aave-v4) separates shared liquidity and accounting in Hubs from borrowing rules in Spokes. Consequently, a token’s presence in one deployment does not establish identical availability or settings in another. Our [Aave protocol guide](/article/aave/) and [lending hub](/lending/) explain the wider mechanics.

The [Sentora curated-Hub proposal](/article/aave-v4-sentora-curated-hub-proposal-september-2026/) is a separate governance development. Its mention of OUSD does not substitute for approval of a DAO core-market listing, and neither story establishes that the other configuration has executed.

## A practical verification table for a new stablecoin market

The following checklist is editorial analysis for evaluating any proposed stablecoin listing. Record dated evidence for the exact network and market; do not infer missing values from another pool.

*Evidence to collect before treating a listing as usable*

| Question | Evidence to inspect | What a missing answer means |
| --- | --- | --- |
| Which token is this? | Issuer, network and complete contract address | The ticker alone cannot identify the asset |
| Has governance executed? | Final payload and successful execution record | Discussion or voting is not activation |
| What can the market do? | Supply, borrow and collateral settings | One permission does not establish another |
| How is the asset valued? | Production oracle, update policy and fallback | A target dollar peg is not a working feed |
| Can funds exit? | Available market cash and separate redemption terms | Lending withdrawal and issuer redemption may differ |
| Who can intervene? | Issuer privileges and protocol emergency roles | Public contracts can still have administrative controls |

## Liquidity and redemption deserve separate checks

[Aave’s withdrawal guidance](https://aave.com/help/supplying/withdraw-tokens) explains that suppliers need enough unborrowed liquidity to withdraw. Taking a token out of a lending pool is therefore different from converting it to bank dollars through an issuer. A third route, selling it on an exchange, depends on that venue’s available liquidity and price.

Our analysis: assess these routes as a sequence. An available lending withdrawal does not prove access to issuer redemption, while a reserve report does not guarantee a particular exchange price. Borrowers should consider how they would obtain the debt token to repay during market stress. Suppliers should consider what happens if many lenders want to leave simultaneously.

Use the [stablecoin research hub](/stablecoins/) to compare design types and the [DeFi due-diligence checklist](/learn/defi-due-diligence-checklist/) to record evidence. A useful research note separates observations, source claims and unresolved questions. This report makes no forecast of yield, adoption or token-price performance.

## Sources, dates and coverage limits

Governance event: 30 September 2026. Original publication and source review: 1 October 2026. The proposal, Open Standard announcement, Bridge reserve page, Origin documentation and Aave documentation linked above were read for this report. The proposed listing is distinct from existing coverage of the Sentora instance and Origin Dollar.

This page reports an announced proposal and explains verification questions. We did not audit deployed contracts, verify reserves independently, execute a transaction or establish personal eligibility for minting or redemption. Updates will follow material verified changes rather than refreshing the publication date simply to appear new.

## Frequently asked questions

- Is the proposed market ready to use? No live listing was verified. Check approved parameters and governance execution before relying on availability.
- Does holding a payments stablecoin automatically earn its reserve income? Do not assume that. Read the issuer’s distribution terms separately from any lending-market interest.
- How should two tokens with the same symbol be distinguished? Match the full name, issuer or protocol, network and complete token contract against official sources.
