# Emergency Controls

### Rescue Tokens

The `rescueTokens` function allows Node owners to recover tokens accidentally sent to the Node that are not part of its components.

```solidity
function rescueTokens(address token, address recipient, uint256 amount) external onlyOwner {
    if (token == asset) revert ErrorsLib.InvalidToken();
    if (_isComponent(token)) revert ErrorsLib.InvalidToken();
    for (uint256 i; i < components.length; i++) {
        try IERC7575(components[i]).share() returns (address share) {
            if (token == share) revert ErrorsLib.InvalidToken();
        } catch {}
    }
    IERC20(token).safeTransfer(recipient, amount);
    emit EventsLib.RescueTokens(token, recipient, amount);
}
```

#### Constraints

* Only Node owner can call
* Cannot rescue Node's underlying asset
* Cannot rescue any token that is a component
* Token must implement ERC20

#### Use Cases

* Recover tokens sent to Node by mistake
* Remove airdrops or other unwanted tokens
* Clean up Node contract of non-component assets

#### Security

The function prevents extraction of:

```solidity
function _isComponent(address component) internal view returns (bool) {
    return componentAllocations[component].isComponent;
}
```

* Node's underlying asset
* Any current component tokens
* Any tokens used in Node strategies
