Fuji1155

This contract tracks all the tokens stored on the Fuji Vaults, simplifying the task of switching protocols for the Flasher. Also helps the Fuji Liquidator in case a user's position is not healthy.

ERC-1155 takes a new approach to defining tokens. Items are now stored in a single contract with the minimum possible amount of data needed to distinguish the token from other ones.

Interface

Fuji1155 is the contract where all tokens are stored - both collateral (ETH) and debt tokens (DAI/USDC).

interface IFujiERC1155 {
  //Asset Types
  enum AssetType {
    //uint8 = 0
    collateralToken,
    //uint8 = 1
    debtToken
  }

General Getter Functions

//General Getter Functions
function getAssetID(AssetType _type, address _assetAddr) external view returns (uint256);

function qtyOfManagedAssets() external view returns (uint64);

function balanceOf(address _account, uint256 _id) external view returns (uint256);

getAssetID: identifies the asset's type and address which can be called externally.

qtyOfManagedAssets: this function gives the overview of all the assets in Fuji Vaults.

balanceOf: generic function to receive an address' balance.

Permit Controlled Functions

function mint(
  address _account,
  uint256 _id,
  uint256 _amount,
  bytes memory _data
) external;

function burn(
  address _account,
  uint256 _id,
  uint256 _amount
) external;

function updateState(uint256 _assetID, uint256 _newBalance) external;

mint: this function mints a new Fuji token when a user deposits collateral into the protocol.

burn: when a Fuji token is redeemd and collateral withdrawn, the burn function burns the Fuji token and thus the debt from the protocol.

updateState: function to update the Fuji1155 account.
