# Price Oracles

### Liquid Restaking Token Pricing

primeETH treats one ETH worth of LST as 1 primeETH, to ensure it remains consistent over time primeETH employs oracles to not overcompensate for LSTs that might be trading at a discounted rate. Thus, as it gets minted with multiple LSTs, the oracles come into play to accurately price respective LSTs as they interact with the platform. 

primeETH currently utilizes the following price oracles:

<table><thead><tr><th width="165">Asset</th><th width="116">Oracle provider</th><th>Address</th></tr></thead><tbody><tr><td>Origin (OETH)</td><td>Origin</td><td>0xc513bDfbC308bC999cccc852AF7C22aBDF44A995</td></tr><tr><td>Lido (stETH)</td><td>Chainlink</td><td>0x86392dC19c0b719886221c78AB11eb8Cf5c52812</td></tr><tr><td>Mantle (mETH)</td><td>Mantle</td><td>0xe3cBd06D7dadB3F4e6557bAb7EdD924CD1489E8f</td></tr><tr><td>Frax (sfrxETH)</td><td>Frax</td><td>0x584902BCe4282003E420Cf5b7ae5063D6C1c182a</td></tr><tr><td>Swell (swETH)</td><td>Redstone</td><td>0x061bB36F8b67bB922937C102092498dcF4619F86</td></tr><tr><td>Rocket Pool (rETH)</td><td>Chainlink</td><td>0x536218f9E9Eb48863970252233c8F271f554C2d0</td></tr><tr><td>Stader (ETHx)</td><td>Redstone</td><td>0xc799194cAa24E2874Efa89b4Bf5c92a530B047FF</td></tr></tbody></table>

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.primestaked.com/security-and-risks/price-oracles.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
