## Minting DLLR stable coin

In order to perform the minting of DLLR assets, the user must own a balance of valid assets: so far, whether Dolar-on-Chain or "DOC" or Zero-Dollar or "ZUSD".

The user must first execute the proper `approve` function to the ERC20 contract of the basic asset.

After such transaction the user can address the execution of `mintTo` to the `MassetManager` contract. The `mintTo` function implies the internal execution of `safeTransferFrom` openzeppeling tool to bring the basic asset to the treasury of `MassetManager` and then the execution of `DLLR.mint` in favor of the user.

```solidity
function mintTo(
        address _bAsset,
        uint256 _bAssetQuantity,
        address _recipient
    ) external nonReentrant returns (uint256 massetMinted) 
```
