How Does OpenEden USDO Work?

RWA|Risk B-|6 mechanisms|4 interactions

OpenEden USDO is a regulated stablecoin that pays you US Treasury yields while you hold it. Backed 1:1 by tokenized US Treasury Bills, USDO earns real yield from the safest asset in traditional finance and passes it to holders automatically. Issued under a Bermuda license and audited by Ernst & Young, it is one of the first regulated yield-bearing stablecoins with a Moody's A-rated backing asset.

Core Mechanisms

Stablecoin/RWA-Backed

USDO: regulated yield-bearing stablecoin pegged 1:1 to USD, fully backed by tokenized US Treasuries (TBILL tokens)

USDO is issued by OpenEden Digital under a Bermuda DABA license. Fully collateralized by TBILL tokens representing US Treasury Bills. Yield from Treasuries accrues to holders automatically. Moody's 'A' rating on TBILL.

Token/Yield-Bearing-Wrapper

Novel

cUSDO: wrapped USDO approved as off-exchange collateral on Binance for institutional use

cUSDO is a wrapped version of USDO approved as the first yield-bearing digital asset for off-exchange custody on Binance. Novel bridge between RWA yield and centralized exchange collateral use cases.

RWA/Tokenized-Treasuries

TBILL: tokenized US Treasury Bill vault with real-time on-chain proof of reserves

TBILL vault offers direct exposure to short-dated US T-Bills via ERC-4626 vault standard. Each TBILL is backed 1:1 by US T-Bills held in segregated accounts. Audited by Ernst & Young and Hacken/Verichains.

Custody/Segregated-Account

Segregated Accounts Company (SAC) structure isolating USDO reserves from OpenEden Group liabilities

OpenEden Digital operates as a Segregated Accounts Company under Bermuda law. USDO reserves are legally separated from corporate liabilities, providing structural protection in case of corporate insolvency.

Oracle/Proof-of-Reserves

Real-time on-chain proof of reserves for TBILL backing USDO

On-chain attestation of reserves provides transparency on USDO's backing. However, proof-of-reserves ultimately relies on the custodian and auditor providing accurate data.

Integration/Multi-Chain

USDO deployed across multiple chains and integrated with DEXs, lending markets, and payment gateways

USDO is live on multiple chains with integrations across DEXs, lending protocols, yield markets, and fiat-crypto payment gateways. Multichain expansion planned for 2026.

How the Pieces Interact

Off-chain US Treasury custodyUSDO peg stabilityHigh

USDO's peg depends entirely on the ability to redeem for US Treasuries held off-chain. Custodian failure, regulatory freeze, or operational issues at the SAC level would break redemption and the peg, even though assets exist off-chain.

Permissionless DeFi integrationUnaudited smart contract exposureMedium

USDO's permissionless nature means third-party protocols can integrate it without OpenEden's review. Users may interact with malicious or unaudited contracts that drain USDO, damaging the token's reputation even though the core protocol is secure.

Bermuda regulatory licenseGlobal user accessMedium

USDO's legitimacy derives from its Bermuda DABA license. If major jurisdictions (US, EU) issue adverse regulatory guidance on offshore-regulated stablecoins, USDO could face exchange delistings or integration restrictions.

US Treasury yieldUSDO holder yield distributionLow

If US Treasury yields drop significantly (e.g., during rate cuts), USDO's yield advantage over non-yield stablecoins (USDC, USDT) diminishes, reducing demand and potentially causing capital outflows.

What Could Go Wrong

  1. Centralized custodian risk — USDO reserves are held by off-chain custodians in segregated accounts; custodian failure or regulatory seizure would break the peg
  2. Regulatory risk from Bermuda Digital Asset Business Act licensing — changes in regulatory stance or cross-border enforcement actions could freeze operations
  3. Permissionless DeFi integration means third-party platforms can integrate USDO without OpenEden's consent, exposing users to unaudited smart contracts

Custodian Failure or Regulatory Seizure

Tail

Trigger: The custodian holding USDO's underlying US Treasuries becomes insolvent, is sanctioned, or has assets frozen by regulatory action, making USDO reserves inaccessible

  1. 1.Custodian holding USDO's Treasury reserves faces regulatory enforcement action or insolvency USDO redemptions are paused as underlying assets become temporarily or permanently inaccessible
  2. 2.USDO depegs on secondary markets as holders cannot redeem 1:1; price drops to $0.80-0.95 DeFi protocols using USDO as collateral face liquidations; lending markets experience bad debt
  3. 3.OpenEden Digital activates SAC legal protections; lengthy legal recovery process begins Funds may eventually be recoverable via legal proceedings but timeline is 6-18 months; liquidity is frozen
  4. 4.Contagion spreads to cUSDO on Binance and other institutional integrations Institutional users face collateral shortfalls; trust in regulated RWA stablecoins broadly damaged
