OZLFacetV1_2

Modifies the original methods from OZLFacet to add and remove tokens from the database in order to support the ability of add/remove tokens from the tokens array, which is the one the front-end needs to display all the stablecoins an user can choose from

Owner methods

addTokenToDatabase

function addTokenToDatabase(
        struct TradeOps calldata newSwap_, 
        struct LibDiamond.Token calldata token_
) external;

Adds a new token to the group of tokens that an user can choose from for an Account as the coin to receive as the final destination on L2.

Due to the nature of the interaction of each token, other details are added besides the address of the token, details such the Curve pool where it can be traded, its base token, etc.

Parameters:

Struct:

struct TradeOps {
    int128 tokenIn;
    int128 tokenOut;
    address baseToken;
    address token;  
    address pool;
}

Name	Type	Description
tokenIn	int128	Index at Curve pool of the base token (USDT or WBTC) of the new token to add
tokenOut	int128	Index at Curve pool of the new token to add
baseToken	address	Base token for swaps
token	address	New token to add
pool	address	Curve pool where the new token to add is found

Struct:

struct Token {
   address l1Address;
   address l2Address;
}

Name	Type	Descritpion
l1Address	address	L1 address of the token to add (it'd be address(0) if bridging is disabled)
l2Address	address	L2 address of the token to add

Function:

Name	Type	Description
newSwap_	struct TradeOps	Configuration of the new token to add
token_	struct LibDiamond.Token	Addresses (L1 and L2) of the token to add

removeTokenFromDatabase

function removeTokenFromDatabase(
        TradeOps calldata swapToRemove_, 
        LibDiamond.Token calldata token_
) external;

Removes a token from the database of tokens that the protocol supports.

Parameters:

The same as addTokenToDatabase()

Function:

Name	Type	Description
swapToRemove_	struct TradeOps	Configuration of the token to remove
token_	struct LibDiamond.Token	Addresses (L1 and L2) of the token to remove
