Origin Dollar (OUSD) is a fully collateralized stablecoin that allows users to passively earn yield while holding it in their wallets. It is backed 1:1 by other stablecoins such as USDC, USDT, and DAI, ensuring a stable value pegged to the US dollar. Users can mint OUSD by converting their stablecoins through the Origin Dollar front-end app, which automatically routes transactions to provide the best available price while considering slippage and gas costs.

Once minted, OUSD begins to accrue compounded yield, which is generated through the deployment of the underlying stablecoins to various DeFi protocols like Aave and Compound. The yield is then distributed to OUSD holders through a constant rebasing of the token supply, ensuring that the OUSD price remains pegged to 1 USD while the user's token balance increases over time.

Redeeming OUSD back for the underlying stablecoins incurs a 0.25% exit fee, which is distributed as additional yield to remaining OUSD holders and serves as a security feature to discourage short-term speculation. The protocol's rebasing function ensures that user balances are protected from daily fluctuations in the prices of the underlying stablecoins.

OUSD can be traded on decentralized exchanges like Uniswap and Curve, as well as on centralized exchanges like Gate.io and KuCoin. It is also accessible through the Origin Dollar dApp, which facilitates buying and selling OUSD tokens. Overall, OUSD provides a reliable store of value and a convenient way to earn passive income in the DeFi ecosystem.
