Architecture

Before we dive deep into the contracts let's have a look at the high-level architecture.

PWN smart contract architecture

PWN

PWN contract serves as the only interface between a user and the protocol.

PWN Vault

PWN Vault is used for storing assets.

PWN LOAN

PWN LOAN is used to store information about LOANs. LOAN is an ERC-1155 token representing a loan in the PWN protocol.

MultiToken

MultiToken is a solidity library that wraps transfer, allowance and balance check calls for ERC20, ERC721 & ERC1155 tokens. Unifying the function calls used within the PWN context, so we don't have to worry about handling these token standards individually.
