DeFiPie - Audit Report

Summary

DeFiPie Audit Report DeFiPie aims to create a financial system that is open to everyone and minimizes the need to rely on central authorities. DeFiPie combines Lending-as-a-Service, Liquidity Pool-as-a-Service, and Staking-as-a-Service all in one platform.

DeFiPie's platform allow users to deposit idle assets to earn interest via lending; and to borrow against collateralized assets to gain access to additional capital. We audited DeFiPie's contracts, accessible at the following link, at commit 1d0d869310c521ae4f42d86e1f511723ab03ea1a on Github. The team appears to have only made minor changes since then.

Audit Findings:
  • Oracle pricing for the project comes from Uniswap's TWAPs (time-weighted average prices), which cannot be manipulated by flash loan attacks.
  • Some functions use tx.origin instead of msg.sender. This is not best in line with solidity best practices (SWC-115), but it prevents contracts from accessing some functions.
  • Admins of the project have the ability to pause features of the platform. Ensure trust in the team; they are public and their actions thus far have proven trustworthy.
  • No security issues from outside attackers were identified.
  • Date: November 30th, 2020

We ran over 400,000 transactions interacting with this suite of contracts on a test blockchain to determine these results.
