Security review and verification record

Euler has commissioned audits and focused reviews across its core contracts, oracles, periphery, integrations, and applications. The record also includes formal verification, fuzzing, penetration tests, and security competitions.

Security competitions and Capture the Flag contests

  • $1.25M Cantina Security Competition — More than 600 participants reviewed the scoped contracts. No high- or medium-severity findings were identified; low-severity and informational findings were rewarded, with $200,000 allocated to researchers.
  • $3.5M Hats Finance CTF Challenge — Approximately $3.5 million in live funds was placed in Euler markets. After 13 days, no funds were compromised.
