# INTRODUCTION

**Protocol** : Origin Dollar

**Website** : [https://ousd.com/](https://ousd.com/)

**Integration** : Price feed for $OUSD. $OUSD is a yield-bearing stablecoin, which deploys users’ underlying capital to a diversified set of yield-earning strategies, rebalancing over time to achieve great yields while diversifying risk.

**Use case** : Will be used for lending markets for OUSD

**Blockchain:** Ethereum

# REQUEST INFORMATION

## Assets

The following assets will be included in the Oracle:

| Asset Ticker | Asset Blockchain | Asset Address | Asset Markets Overview | Trades Aggregation Window Size |
| --- | --- | --- | --- | --- |
| OUSD | Ethereum | [0x2A8e…5e86](https://etherscan.io/address/0x2A8e1E676Ec238d8A992307B495b45B3fEAa5e86) | [OUSD markets](https://www.diadata.org/app/price/asset/Ethereum/0x2A8e1E676Ec238d8A992307B495b45B3fEAa5e86/) | 120 sec |

## Methodology

Select the methodologies that will define the feeds:

- Volume Weighted Average Price with Interquartile Range (VWAPIR) will be used to calculate the price for the assets. Learn more about it [here](https://docs.diadata.org/documentation/methodology/exchangeprices/mair-moving-average-with-interquartile-range-filter)

- 2% deviation threshold for updates trigger will be applied

- 120s trades aggregation window size will be applied

- The feed will be updated every 24h period if there are no deviation based updates

# DELIVERY INFORMATION

Select if the feed should be delivered on-chain via oracle and if so, which network:

- **Delivery method** : Oracle on Ethereum

- **Testnet required** : No

# NOTES

Additional relevant information:

- Delivery estimate: 10 days

Thank you for requesting a data feed via DIA CDR. We confirm the CDR specifications were requested correctly. Find the oracle information below:

### Oracle

The oracle is deployed and can be accessed [here](https://etherscan.io/address/0xafa00e7eff2ea6d216e432d99807c159d08c2b79).

You can query for assets by calling the read function getValue() with parameters such as “OUSD/USD”. It will return two values:

1. The price of the asset queried with 8 decimals
2. The unix timestamp of the last update

You can see Solidity and Vyper code integration examples [here](https://docs.diadata.org/introduction/intro-to-dia-oracles/access-the-oracle#oracle-integration-example) or use a dedicated DIA oracles integration library described in detail [here](https://docs.diadata.org/introduction/intro-to-dia-oracles/access-the-oracle#accessing-dias-oracles-with-a-dedicated-solidity-library).

### Funding

Each deployed oracle has a separate gas wallet which is the only entity allowed to update oracle values based on selected parameters. To find out more information on how it works, visit the following [link](https://docs.diadata.org/introduction/intro-to-dia-oracles/oracle-funding).

Please make sure to top up the gas wallet, as we only put in some gas to deploy and start the oracle.

Gas Wallet address: [0x3a4b859279998e5841e4f305b9b43e63e2f57645](https://etherscan.io/address/0x3a4b859279998e5841e4f305b9b43e63e2f57645)

### Markets

You can view the markets included for each feed by pressing on a link to DIA App in the deployed assets list:

1. [Ethereum-0x2A8e1E676Ec238d8A992307B495b45B3fEAa5e86](https://app.diadata.org/price/asset/Ethereum/0x2A8e1E676Ec238d8A992307B495b45B3fEAa5e86/?asset=OUSD)

Note: DIA uses Blockchain-Address querying formatting to ensure asset selection precision (token symbols might duplicate)

You can also query current asset prices and find other market information on the asset by using the DIA API as described [here](https://docs.diadata.org/products/token-price-feeds/access-api-endpoints).

I would like to request addition of an OETH/ETH oracle as well:

Contract: [Origin Protocol: OETH Token | Address 0x856c4Efb76C1D1AE02e20CEB03A2A6a08b0b8dC3 | Etherscan](https://etherscan.io/address/0x856c4Efb76C1D1AE02e20CEB03A2A6a08b0b8dC3)

Dear team,  
the OETH/ETH oracle has been deployed. This consists of two parts:

First, the existing oracle is now receiving feeds of OETH/USD and ETH/USD. Each time OETH/USD is updated, an update for ETH/USD is also made to ensure the update timing coincidence of both assets.

Second, an adapter contract has been deployed at [0xab9e20e8ab03c4f9476531b3ba3a0fc522cd0faa](https://etherscan.io/address/0xab9e20e8ab03c4f9476531b3ba3a0fc522cd0faa) to retrieve the value of OETH/ETH directly.  
To do taht, just call `getAPriceInB()` to receive the price of OETH in ETH (with 8 decimals) and the timestamps of the two underlying updates.  
We recommend to check that these timestamps are closely together to ensure freshness of the data when you call this function.

Hello,

Peter here again from Origin. I would like to request addition of a superOETHb/ETH oracle on Base.

Asset markets: [superOETHb | Super OETH API & Price Oracle | DIA](https://www.diadata.org/app/price/asset/Base/0xDBFeFD2e8460a6Ee4955A68582F85708BAEA60A3/)

Thank you for requesting a data feed via DIA CDR. We confirm the CDR specifications were requested correctly. Find the oracle information below:

### Oracle

The oracle is deployed and can be accessed [here](https://basescan.org/address/0x4a622611b790d579875a2c096ec2947f148ad17c).

The adapter for querying the ratio SUPEROETHB/ETH is located [here](https://basescan.org/address/0x98E2B416BC536c1AC9f91504362123813196541B).

You can query for assets by calling the read function getValue() with parameters such as “SUPEROETHB/USD”. It will return two values:

1. The price of the asset queried with 8 decimals
2. The unix timestamp of the last update

In the adapter contract you can call `getAPriceInB()` to to retrieve the value of SUPEROETHB/ETH directly. We recommend to check that these timestamps are closely together to ensure freshness of the data when you call this function.

You can see Solidity and Vyper code integration examples [here](https://docs.diadata.org/introduction/intro-to-dia-oracles/access-the-oracle#oracle-integration-example) or use a dedicated DIA oracles integration library described in detail [here](https://docs.diadata.org/introduction/intro-to-dia-oracles/access-the-oracle#accessing-dias-oracles-with-a-dedicated-solidity-library).
