Token Listener

The Prize Pool Token Listener interface allows contracts to "listen" to the complete token lifecycle of mint, transfer and burn. There are two functions that must be implemented: beforeTokenMint and beforeTokenTransfer

The beforeTokenMint function must be called whenever a token is minted.

function beforeTokenMint(
    address to,
    uint256 amount,
    address controlledToken,
    address referrer
) external;

Paramater Name	Parameter Description
to	The address that is receiving the newly minted tokens
amount	The amount of new tokens
controlledToken	The token being minted
referrer	The address that referred the user (for rewards)

The beforeTokenTransfer function must be called whenever a token is transferred or burned.

function beforeTokenTransfer(
    address from,
    address to,
    uint256 amount,
    address controlledToken
) external;

Paramater Name	Parameter Description
from	The address that is sending the tokens
to	The address that is receiving tokens. May be the zero address if burning.
amount	The amount of tokens
controlledToken	The token being transferred
