OUSD's balance growth comes from automatic compounding, with no staking or locking required. The USDC you deposit is used by the protocol to earn yield on Morpho and Curve, and the yield is added directly to your OUSD balance daily. However, the short-term growth rate of your balance won't always exactly match the APY number shown on the page, because compounding happens in batches.

Balance Growth: Added Directly to Your Wallet, No Claiming Needed
OUSD is a positive rebase stablecoin. Yield is not airdropped to you as new tokens; instead, it directly increases the amount of OUSD in your wallet, while keeping 1 OUSD = 1 USD. You don't have to do anything—your balance grows on its own.
Rebasing is triggered at least once a day, automatically by normal user interactions and Chainlink Keepers. Each time it triggers, the yield earned by the protocol since the last rebase is distributed proportionally to all eligible holders.
But the balance growth is not linear. Origin's official FAQ explains that the size of each rebase varies a lot, depending on how much the vault has earned since the previous rebase. Some rebases only receive small yields from lending strategies, while others involve liquidation reward tokens or fee collection. So in the short term, you may see your balance grow faster or slower than the advertised APY. This is normal—don't try to annualize based on a single rebase.
Where Yield Comes From: Morpho Lending + Curve Market-Making
OUSD's USDC collateral is mainly deployed in two places:
Morpho lending is the primary yield source. Origin and Yearn jointly manage a Morpho vault specifically designed for OUSD. Funds are lent to USDC markets on Morpho, earning interest paid by borrowers. Yearn handles day-to-day capital allocation, adjusting weights across different markets within the risk parameters set by Origin. The market access criteria are: the market must have deep liquidity, and the collateral must be audited blue-chip assets.
Curve market-making is a secondary source, typically not exceeding 20% of the USDC collateral. The protocol provides liquidity in the OUSD/USDC pool on Curve, earning trading fees and CRV rewards. This pool also serves another purpose: it provides swap liquidity for holders who want an instant exit without going through the redemption process.
The yield amplification mechanism is a design feature of OUSD. Certain smart contracts (like OUSD in Uniswap pools) do not participate in rebases, meaning those OUSD tokens do not receive yield. But their USDC collateral is still earning yield—and that yield is distributed to regular OUSD holders. Origin calls this a "yield bonus." Currently, OUSD's yield amplification is roughly 1.66x. This is why OUSD's yield is usually higher than directly depositing into Morpho or Curve.
Redemption: Two Paths, Choose Based on Amount and Speed Needs
Path 1: Redeem through the Origin dapp. In the dapp, you can swap OUSD 1:1 back to USDC with no slippage. Origin's docs say redemption is "always available," but in practice, small amounts are instant while large amounts may need to wait. Redemption is free—there is no exit fee.
Path 2: Swap on Curve. If you want USDC instantly, you can swap directly in the OUSD/USDC pool on Curve. This involves slippage, and the pool depth determines how much you get. The pool's liquidity is maintained by the protocol itself, so it's usually sufficient, but for large operations, it's still better to check the pool status first.
How large redemptions actually work: Origin's redemption mechanism is asynchronous—minimum 10 minutes, and up to 24 hours when liquidity needs to recover. The official recommendation for large exits is to split them into multiple smaller redemptions, which makes instant execution more likely.
Risks: Know Where the Money Goes and What Has Happened Before
Smart contract risk is the primary risk. OUSD's funds pass through external protocols like Morpho and Curve, and vulnerabilities in those protocols directly affect OUSD. In November 2020, OUSD suffered a $7 million exploit, where an attacker drained funds through a reentrancy bug, and OUSD's price briefly dropped to $0.14. Afterwards, Origin made full compensation (full amount for the first 1000 OUSD, with OUSD + OGN compensation for the excess) and strengthened security measures. But this incident shows: the combination of rebase stablecoins and DeFi strategies is not zero-risk.
Utilization risk. Morpho is a peer-to-peer lending market. If a market's utilization rate reaches 100% (all funds are lent out), OUSD cannot withdraw from that market and must wait for borrowers to repay or new funds to enter. Yearn continuously monitors and manually rebalances, but automated tools are still on the roadmap. This means under extreme market conditions, large redemptions may be delayed.
USDC counterparty risk. OUSD is 100% backed by USDC, and USDC is a centralized stablecoin issued by Circle. Circle has the power to freeze USDC at specific addresses. OUSD inherits this layer of risk.
A practical assessment: OUSD is suitable for people who want stablecoin yield but don't want to actively manage DeFi positions. Its balance growth is automatic, redemption paths are clear, and yield sources are relatively transparent (Morpho + Curve). But the 2020 exploit and the asynchronous redemption mechanism remind you: this is not an "absolutely safe" savings account. If you need to withdraw a large amount of USDC anytime, without delay, you may want to test the redemption speed in advance, or keep a portion in the Curve pool.
