# ScaledToken

### Key functions:

```solidity
function mint(
    address user,
    uint256 amount,

) external onlyUTokenVault returns (uint256)
```

Mints new scaled tokens to a specified address.

### Parameters:

`account`: The address to mint tokens to.

`amount`: The amount of tokens to mint.

`liquidityIndex`: The liquidity index at the time of minting.

***

```solidity
function burn(
    address user,
    uint256 amount,
    uint256 index
  ) external onlyUTokenVault returns (uint256)
```

Burns scaled tokens from a specified address.

### Parameters:

`account`: The address to burn tokens from.

`amount`: The amount of tokens to burn.
