# Contracts and Integrations

Deployed contract addresses, oracle feeds, and integration guides for building on ether.fi.

Everything you need to build on ether.fi. The protocol's smart contracts are fully open-source, and weETH is integrated across the DeFi ecosystem on Ethereum and major L2s.

ether.fi's smart contracts are available on GitHub: [github.com/etherfi-protocol/smart-contracts](https://github.com/etherfi-protocol/smart-contracts)

## Price feeds

You can integrate weETH into your DeFi platform using **RedStone Oracles** on Ethereum, Arbitrum, and other L2s. See the available feeds and addresses in the [RedStone documentation](https://docs.redstone.finance/docs/smart-contract-devs/price-feeds).

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://etherfi.gitbook.io/etherfi/developers/contracts-and-integrations.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
