# Price Oracles
_(Requires the [PriceOracle amendment][] {% not-enabled /%})_
Blockchains can't inherintly interact with and "know" what's happening off the network, but many of its use cases in decentralized finance require this information.
Price oracles solve this problem. An oracle is a service or technology that gathers real-world information, such as market prices, exchange rates, or interest rates, and relays it to the blockchain. Like blockchains, most oracles are also decentralized and validate data through multiple nodes.
{% admonition type="info" name="Note" %}
Oracles aren't limited to only providing financial information. It can provide any type of info, such as what sports team won a game, or even the weather. The oracle implementation on the XRP Ledger, however, only gathers the price of assets.
{% /admonition %}
## How Oracles Works
Most oracle blockchain interactions work like this:
1. An oracle validates data on its network.
2. The data is sent to the blockchain.
3. The blockchain uses that information to execute a smart contract, such as releasing funds from an escrow.
This process can also work in reverse, pushing transaction information to external systems.
## Price Oracles on the XRP Ledger
XRPL price oracles are a native, on-chain oracle, enhancing the native DeFi functionality of the XRP Ledger. Off-chain price oracles send their data to XRPL oracles, which store that information on-chain. Decentralized apps can then query the XRPL oracles for price data; multiple XRPL oracles can be queried to minimize risk and inaccuracies.
By standardizing price feeds in this manner, all XRPL apps can access a dependable, shared data source.

"PreviousTxnLgrSeq": 56865244
}
```
## Oracle Fields
| Field | JSON Type | Internal Type | Required? | Description |
|---------------------|-----------|---------------|-----------|-------------|
| `Owner` | String | AccountID | Yes | The XRPL account with update and delete privileges for the oracle. It's recommended to set up [multi-signing](https://xrpl.org/set-up-multi-signing.html) on this account. |
| `Provider` | String | Blob | Yes | An arbitrary value that identifies an oracle provider, such as Chainlink, Band, or DIA. This field is a string, up to 256 ASCII hex encoded characters (0x20-0x7E). |
| `PriceDataSeries` | Array | Array | Yes | An array of up to 10 `PriceData` objects, each representing the price information for a token pair. More than five `PriceData` objects require two owner reserves. |
| `LastUpdateTime` | Number | UInt32 | Yes | The time the data was last updated, represented in Unix time. |
| `URI` | String | Blob | No | An optional Universal Resource Identifier to reference price data off-chain. This field is limited to 256 bytes. |
| `AssetClass` | String | Blob | Yes | Describes the type of asset, such as "currency", "commodity", or "index". This field is a string, up to 16 ASCII hex encoded characters (0x20-0x7E). |
| `OwnerNode` | String | UInt64 | Yes | A hint indicating which page of the oracle owner's owner directory links to this entry, in case the directory consists of multiple pages. |
| `PreviousTxnID` | String | UInt256 | Yes | The hash of the previous transaction that modified this entry. |
| `PreviousTxnLgrSeq` | String | UInt32 | Yes | The ledger index that this object was most recently modified or created in. |
### PriceData Fields
| Field | JSON Type | Internal Type | Required? | Description |
|---------------------|-----------|---------------|-----------|-------------|
| `BaseAsset` | String | Currency | Yes | The primary asset in a trading pair. Any valid identifier, such as a stock symbol, bond CUSIP, or currency code is allowed. For example, in the BTC/USD pair, BTC is the base asset; in 912810RR9/BTC, 912810RR9 is the base asset. |
| `QuoteAsset` | String | Currency | Yes | The quote asset in a trading pair. The quote asset denotes the price of one unit of the base asset. For example, in the BTC/USD pair, USD is the quote asset; in 912810RR9/BTC, BTC is the quote asset. |
| `AssetPrice` | Number | UInt64 | No | The asset price after applying the `Scale` precision level. It's not included if the last update transaction didn't include the `BaseAsset`/`QuoteAsset` pair. |
| `Scale` | Number | UInt8 | No | The scaling factor to apply to an asset price. For example, if `Scale` is 6 and original price is 0.155, then the scaled price is 155000. Valid scale ranges are 0-10. It's not included if the last update transaction didn't include the `BaseAsset`/`QuoteAsset` pair. |
## Oracle ID Format
The ID of an `Oracle` object is the [SHA-512Half](https://xrpl.org/basic-data-types.html#hashes) of the following values, concatenated in order:
1. The `Oracle` space key (`0x52`)
2. The `Owner` Account ID.
3. The `OracleDocumentID`.
## Currency Internal Format
The `Currency` field type represents a standard currency code, such as XRP, or an arbitrary asset as a 160-bit (40 character) hexadecimal string. This type is generally conformant to the XRPL [currency codes](https://xrpl.org/currency-formats.html#standard-currency-codes) format. Below is a JSON example with `BaseAsset` representing a CUSIP code `912810RR9` as a 160-bit hexadecimal string and `QuoteAsset` representing a standard `USD` currency code:
```json
{
"PriceData" : {
"BaseAsset" : "3931323831305252390000000000000000000000",
"QuoteAsset" : "USD",
"Scale" : 1,
"SymbolPrice" : 740
}
}

Creates a new `Oracle` ledger entry or updates the fields of an existing one, using the Oracle ID.
The oracle provider must complete these steps before submitting this transaction:
1. Create or own the XRPL account in the `Owner` field and have enough XRP to meet the reserve and transaction fee requirements.
2. Publish the XRPL account public key, so it can be used for verification by dApps.
3. Publish a registry of available price oracles with their unique `OracleDocumentID`.

| `AssetClass` | String | Blob | Variable | Describes the type of asset, such as "currency", "commodity", or "index". This field is a string, up to 16 ASCII hex encoded characters (0x20-0x7E). This field is required when creating a new `Oracle` ledger entry, but is optional for updates. |
| `PriceDataSeries` | Array | Array | Yes | An array of up to 10 `PriceData` objects, each representing the price information for a token pair. More than five `PriceData` objects require two owner reserves. |
### PriceData Fields

| `AssetPrice` | Number | UInt64 | No | The asset price after applying the `Scale` precision level. It's not included if the last update transaction didn't include the `BaseAsset`/`QuoteAsset` pair. |
| `Scale` | Number | UInt8 | No | The scaling factor to apply to an asset price. For example, if `Scale` is 6 and original price is 0.155, then the scaled price is 155000. Valid scale ranges are 0-10. It's not included if the last update transaction didn't include the `BaseAsset`/`QuoteAsset` pair.|
`PriceData` is created or updated, following these rules:
- New token pairs in the transaction are added to the object.
- Token pairs in the transaction overwrite corresponding token pairs in the object.
- Token pairs in the transaction with a missing `AssetPrice` field delete corresponding token pairs in the object.
- Token pairs that only appear in the object have `AssetPrice` and `Scale` removed to signify that the price is outdated.
**Note:** The order of token pairs in the transaction aren't important because each token pair uniquely identifies the location of the `PriceData` object in the `PriceDataSeries`.
## Reserve Requirements
The owner reserve requirement is 1 for one to five `PriceData` objects, and 2 for six to ten `PriceData` objects.
## Error Cases
Besides errors that can occur for all transactions, `OracleSet` transactions can result in the following transaction result codes.
| Error Code | Description |
|---------------------------|-------------|
| `temARRAY_EMPTY` | The `PriceDataSeries` has no `PriceData` objects. |
| `tecARRAY_TOO_LARGE` | The `PriceDataSeries` exceeds the ten `PriceData` objects limit. |
| `tecINVALID_UPDATE_TIME` | The `Oracle` object has an invalid `LastUpdateTime` value. |
| `tecTOKEN_PAIR_NOT_FOUND` | The token pair you're trying to delete doesn't exist in the `Oracle` object. |
| `tecARRAY_EMPTY` | The `PriceDataSeries` has no `PriceData` objects. |
| `temARRAY_TOO_LARGE` | The `PriceDataSeries` exceeds the ten `PriceData` objects limit. |
