# FAQ

**Where can I acquire Origin's yield-bearing tokens?**

OETH, OUSD, and Super OETH can be acquired in the [Origin dapp](https://app.originprotocol.com/).

**What is an AMO?**

Algorithmic Market Operations (AMO) are smart contracts that automatically execute monetary policies within specific protocols. These policies can be applied to internal systems or external platforms like Curve. AMOs can mint new tokens and add them to liquidity pools or lend them to money markets when certain conditions are met. See [more here](/yield-bearing-tokens/core-concepts/amo.md).

**What fees are charged by the protocol?**

Origin Protocol takes a 20% fee on yield generated by OETH, Super OETH, OUSD, and ARM Vaults. All fees are used to buyback OGN and distribute it as staking rewards to xOGN. APYs displayed on analytics and the Origin dapp are net of fees.

**How soon will my OUSD, OETH, or Super OETH balance increase?**

Your balance of OUSD, OETH, or Super OETH will increase with each positive rebase event. These rebases occur several times a day and are linked to the minting and redeeming activity. For more details, refer to the Elastic Supply documentation.

**How is it possible for the APY to be so high?**

You can read about our various strategies in [Yield Generation](broken://pages/21VD2AtjUIyd0vy5EOd6). We currently get most of the yield from harvesting rewards tokens. Additionally, the yield increases as more OUSD, OETH, and Super OETH are held in smart contracts that do not opt into rebasing since the underlying collateral continues to earn for the remaining holders.

**Why is my balance increasing at a slower rate than the advertised APY?**

Balances increase when the supply is rebased. But the size of each rebase varies wildly depending on how much the vault has earned since the last rebase. And while most rebases collect a small amount of earnings from lending strategies, other rebases involve liquidating rewards tokens or collecting fees. As a result, the yield will vary significantly during short periods of time.
