Security Overview

Introduction

Euler stands as one of the most rigorously and extensively audited DeFi projects in the world. Its modular architecture isolates risk, makes code easier to test, analyze, and audit, and helps reduce single points of failure. For a detailed overview of the steps taken to secure Euler, you can explore a dedicated blog post on the topic here.

Security Measures

Code Security​

  • Extensive Auditing: The protocol codebase has undergone over 40 security reviews conducted by more than 16 of the world's leading web3 security firms.
  • Advanced Testing: The protocol's robustness is reinforced by extensive testing libraries, including bespoke fuzz testing and a formal verification testing suite.
  • Security Competitions: Before its launch, Euler underwent a record-breaking $1.25M Cantina security competition, with only low-severity and informational findings reported.
  • Battle Testing: Following its release, the protocol was battle-tested in a $3.5M capture-the-flag (CTF) challenge hosted by Hats Finance.

Ongoing Security​

  • Bug Bounty Program: Euler features an active bug bounty program on Cantina, offering rewards of up to $5M.
  • Active Monitoring: Leading security platforms provide active monitoring of all operational networks.
  • Emergency Response: A comprehensive pause and upgrade system allows for quick response to potential threats.

Application Security​

  • User Interface: The user interface has been audited to ensure it adheres to best-in-class security practices and is protected by Cloudflare.
  • Infrastructure: Advanced security measures protect against DDoS attacks, DNS spoofing, and other common threats.
  • Compliance: The application adheres to ISO 27001 standards through comprehensive internal policies.
