The Euler exploit ended with a rare large-scale return of funds
In March 2023 Euler Finance reported an exploit; the attacker later returned most of the funds after negotiations and a public response.
The incident involved a vulnerability in a lending-market configuration and demonstrated how quickly an exploit can threaten users across integrated protocols.
The recovery drew attention, but it was an exceptional outcome rather than a reliable incident-response model.
Users should treat post-hack negotiations as uncertain; protocol security and clear response plans remain the primary safeguards.
