# Peer-to-Peer Pool

## Overview

In the current lending pool, there is an interest rate difference between the Suppliers and the Borrowers. Supplied amounts are much larger than borrowed amounts, but the interest generated by borrowers is evenly distributed to all suppliers. The purpose of launching a Peer-to-Peer pool is to solve this mismatch of assets between borrowers and suppliers. When no Peer-to-Peer pairing is formed (When there is no Peer-to-Peer pairing) , the funds will be deposited in the ordinary lending pool to enjoy normal supply APR. When the funds are paired, they will be withdrawn to the Peer-to-Peer pool. Then the Supply APR of the suppliers increases, and the Borrow APR of the borrowers decreases, so that both sides can obtain the optimal solution.

## Supported Assets

All supported assets are Ethereum based assets.
