Pool V2

Overview

This repository contains the core contracts of the Maple V2 protocol that are responsible for the deployment and management of Maple Pools:

Contract	Description
Pool	Each pool represents a different lending pool with a unique strategy and pool delegate that issues loans on behalf of the liquidity providers. The Pool contract is compatible with the ERC-4626 Tokenized Vault standard.
PoolManager	Used by the pool delegate to manage pool level parameters and to issue loans to borrowers.
PoolDelegateCover	Holds first-loss capital in escrow on behalf of the pool delegate.
PoolDeployer	Used to deploy new pools with all the required dependencies.

Dependencies/Inheritance

Contracts in this repo inherit and import code from:

• maple-labs/erc20
• maple-labs/erc20-helper
• maple-labs/maple-proxy-factory

Contracts inherit and import code in the following ways:

• Pool inherits ERC20 for fungible token functionality.
• PoolDelegateCover, PoolDeployer and PoolManager use ERC20Helper for token interactions.
• PoolManager inherits MapleProxiedInternals for proxy logic.
• PoolManagerFactory inherits MapleProxyFactory for proxy deployment and management.

Versions of dependencies can be checked with git submodule status.
