# Deposit Pipe

The DepositPipe handles deposits and implements ERC4626 compatibility. Each DepositPipe handles a specific asset, meaning that for a given xToken there can be multiple DepositPipe (1 per accepted deposit asset).

**Key Functions**

**`deposit(uint256 assets, address receiver, address controller, uint256 minShares)`**

Deposit assets and receive shares with slippage protection.

```solidity
/**
 * @param assets Amount of deposit asset (in asset's native decimals)
 * @param receiver Address to receive minted shares
 * @param controller Address that owns the assets being deposited
 * @param minShares Minimum shares to receive (slippage protection, 18 decimals)
 * @return shares Amount of shares minted (18 decimals)
 */
function deposit(
    uint256 assets,
    address receiver,
    address controller,
    uint256 minShares
) external returns (uint256 shares);
```

**Overloads:**

* `deposit(uint256 assets, address receiver)` - Uses `msg.sender` as controller, no slippage protection
* `deposit(uint256 assets, address receiver, address controller)` - No slippage protection
* `deposit(uint256 assets, address receiver, uint256 minShares)` - Uses `msg.sender` as controller

***

**`mint(uint256 shares, address receiver, address controller, uint256 maxAssets)`**

Mint specific amount of shares by depositing assets.

```solidity
/**
 * @param shares Exact amount of shares to mint (18 decimals)
 * @param receiver Address to receive shares
 * @param controller Address that owns the assets
 * @param maxAssets Maximum assets willing to spend (slippage protection, native decimals)
 * @return assets Amount of assets deposited (native decimals)
 */
function mint(
    uint256 shares,
    address receiver,
    address controller,
    uint256 maxAssets
) external returns (uint256 assets);
```

**Overloads:**

* `mint(uint256 shares, address receiver)` - Uses `msg.sender`, no slippage limit
* `mint(uint256 shares, address receiver, address controller)` - No slippage limit
* `mint(uint256 shares, address receiver, uint256 maxAssets)` - Uses `msg.sender`
