# Adapter Framework

The Tetrics Adapter Framework provides a flexible, registry-based system for integrating DeFi protocols without enforcing rigid interfaces.

### How It Works

#### Protocol Registration

* Each adapter is registered with UniExecutor by protocol name (e.g., "lido", "morpho").
* Executor maintains a mapping: `mapping(string => address) public protocols`.
* Actions specify the protocol name and method to call.

#### BaseAdapter Foundation

* All adapters inherit from `BaseAdapter` (`src/adapters/BaseAdapter.sol`).
* Provides common utilities: token transfers, approvals, balance management.
* No enforced function signatures - adapters define their own interfaces.

#### Protocol-Specific Methods

Each adapter exposes methods specific to its protocol. Examples include:

* **LidoAdapter**:
  * `deposit(uint256 amount)`
* **MorphoAdapter**:
  * `supply(uint256 amount)`
  * `borrow(uint256 amount)`
* **FelixAdapter**:
  * `openCdp(address collateral, uint256 amount)`

#### Dynamic Method Calls

* UniExecutor uses low-level calls to invoke adapter methods.
* Action struct encodes the method signature and parameters.
* Flexibility to support any protocol without interface changes.

#### Adapter Structure

**Example: LidoAdapter**

```solidity
contract LidoAdapter is BaseAdapter {
    address public immutable executor;
    address public immutable stETH;

    constructor(address _executor, address _stETH) {
        executor = _executor;
        stETH = _stETH;
    }

    /// @notice Stake ETH and receive stETH
    function deposit(uint256 amount) external payable returns (uint256) {
        // Protocol-specific implementation
        // ...
    }
}
```

# 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://tetrics.gitbook.io/x/architecture/adapter-framework.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.
