### Summary

This proposal seeks to list cUSDO, a non-rebasing, yield-bearing stablecoin issued by OpenEden, as a new market on Moonwell Base. cUSDO is a wrapped version of USDO — a stablecoin backed 1:1 by U.S. Treasury Bills — and allows users to earn real-world yield while participating in DeFi lending, borrowing, and collateralization within the Moonwell ecosystem.

* * *

### Motivation

Integrating cUSDO brings several benefits to Moonwell:

- Capital Efficiency – Supply cUSDO, earn passive yield, and use it as collateral simultaneously.
- Real-World Yield – Backed by U.S. T-Bills through OpenEden’s USDO vault.
- Non-Rebasing = DeFi Ready – cUSDO maintains ERC-20 compatibility, avoiding issues of rebasing tokens.
- Institutional-Grade Structure – Transparent, regulated custodianship, real-time reserve attestation.

This listing would further Moonwell’s mission to bridge DeFi and real-world assets (RWAs).

2. **TVL Requirements**  
Combined TVL of USDO and cUSDO \> $40M across Base and other chains.  

3. **Security & Audit**

- Fully verified contract
- Standard role-based access controls for mint/burn
- Third-party audit by ChainSecurity (no critical vulnerabilities)
- [Transparent](https://openeden.com/usdo/transparency) reserves and regulated custodians

1. **Market Caps**

- on BASE: 3.5M
- on ETHEREUM: 214M

1. **Total Transactions**

- on BASE: 65K transfers & 15K direct txs & 9K holders
- on ETHEREUM: 60K transfers & 9K direct txs & 2K holders

1. **Age of Token**

- on BASE: 131 days
- on ETHEREUM: 237 days

### Smart Contract Review

Contract: [`cUSDO`](https://basescan.org/address/0x83db73ef5192de4b6a4c92bd0141ba1a0dc87c65#code)

- **Proxy Architecture:**  
The cUSDO contract is deployed as an `ERC1967Proxy`.

- **Base Contracts:**  
The [logic](https://basescan.org/address/0xc9c0479cd63ffd5e116430189a9eb6550617f287#code) implementation inherits from OpenZeppelin’s battle-tested upgradeable libraries:

- **Permission Structure:**  
Role-based access is enforced using `AccessControl`. Critical roles include:

- **Security Observations:**

- **Blacklist Functionality:** No.

- **Is the token pausable?** Yes.

- **Does the project have an active bug bounty program?** No.

### Why List cUSDO Instead of USDO

| Feature | USDO | cUSDO |
| --- | --- | --- |
| **Token Type** | Rebasing | Non-rebasing |
| **DeFi Compatibility** | Limited | Full (ERC-20 standard) |
| **Interest Handling** | Balance increases via rebasing | Value increases via internal exchange rate |
| **Use as Collateral** | Problematic | Seamless |
| **Price Oracle** | Less practical | Available via Chainlink |

### Reserve Attestation Transparency

OpenEden’s USDO vaults are backed 1:1 by U.S. Treasury Bills. Reserve holdings are verified via a live [Chainlink Proof-of-Reserves (PoR) oracle](https://data.chain.link/feeds/base/base/usdo-por), ensuring transparency and onchain trust in the asset’s collateralization.

### [Risk](https://docs.openeden.com/usdo/risks) Considerations

To ensure safe integration, the following risks should be reviewed:

- [RWA Exposure](https://docs.openeden.com/tbill/trust-and-transparency#audit-and-attestations) – USDO is backed by U.S. T-Bills. Low volatility but subject to regulatory or market shifts.
- Centralization – While the token is issued by a regulated entity (OpenEden Digital Limited), it remains a centralized asset in terms of custody and minting permissions. However, it uses independent custodians (e.g., Zodia Custody) and a bankruptcy-remote trust structure to mitigate this.
- Oracle Risk - Chainlink’s native cUSDO/USD price feed is live and operational on Base, ensuring a decentralized and reliable price source. It uses a time-weighted average price (TWAP) model to reduce volatility or manipulation.
- And Of Course Smart Contracts Risk!

### Conclusion

cUSDO is a strong candidate to expand Moonwell’s Base markets with a secure, transparent, and yield-generating RWA-backed asset. The combination of Chainlink oracles, proof of reserves, and OpenZeppelin-based upgradeable contracts offers both transparency and safety.

We look forward to the community’s feedback and collaboration to move this proposal forward.

# Assessing cUSDO via the MALF

# Summary

The [Moonwell Asset Listing Framework (MALF)](https://forum.moonwell.fi/t/moonwell-asset-listing-framework-v2/724) provides the community with a recommended set of requirements that should be met when listing new assets on Moonwell. This initial assessment from Boardroom is meant to be a **first-pass look** at whether or not the proposal meets these minimum criteria; this is **not meant as an official endorsement nor rejection of the asset**. If the author is able to provide any missing information, we will edit our comment to reflect whether or not the proposal adheres to the MALF.

Based on the information outlined below, the **cUSDO proposal does not meet the minimum asset listing requirements.**

### Proposal Requirements

| Requirement | Has the Requirement been met? |
| --- | --- |
| Forum Post: Was the proposal submitted with the correct “Add [ASSET SYMBOL] market to Moonwell on [Network]” format? | Yes |
| Forum Post: Was it posted in the “[Community Proposals](https://forum.moonwell.fi/c/proposals/community-proposal/19)” category? | Yes |

| --- | --- |
| **General** : Token asset name | Yes |
| **General** : A description of the project and the token | Yes |
| **General** : Benefits to the Moonwell community | Yes |
| **General** : Resources (website, social media, docs) | Yes |
| **General** : Author’s contact information | Yes |
| **General** : Relationship between the author and the token | Yes |
| **Market Risk Assessment** : Market cap of the token | Yes |
| **Market Risk Assessment** : Total supply | No |

| **Decentralization** : List of all privileged roles in the token contract (whitelisted EOAs, multi-sigs, or DAOs) | No |
| **Decentralization** : Pausability of the token? | Yes |
| **Decentralization** : Does it have a blacklist? | Yes |
| **Codebase & Onchain Activity** : Github repo for token contracts | Yes |
| **Codebase & Onchain Activity** : Basescan/Moonscan/Etherscan links with verified contracts | Yes |
| **Codebase & Onchain Activity** : Age of token (days) | Yes |

| **Additional Requirements** : Swap size requirement ($500K swap incurs a 25% price impact or less across DEXs and/or aggregators) | Yes |
| **Additional Requirements** : Liquidity threshold (at least $2M total TVL across DEX pools) | No |
| **Additional Requirements** : Commercial Viability (potential to generate at least $1K/mo in protocol revenue) | No |

### Notes

The liquidity threshold requirement cannot be met with combined liquidity across the wrapped asset and the underlying asset. [USDC/cUSDO TVL](https://aerodrome.finance/liquidity?query=cusd) on Aerodrome on Base is currently sitting ~$1.58M, which falls short of the required $2M. As Moonwell is not deployed on Ethereum, we can’t consider the cUSDO/USDC Curve pool. Other information that is missing from this proposal includes total supply, largest exchange information, volatility, average trading volume, list of privileged roles in the token contract, emergency contacts, some upgradeability information, further information on the wrapping mechanics, and commercial viability.
