A day after DeFi platform Euler Finance was hacked for nearly $200 million, the company sent a message to the thieves in a very DeFi way: on-chain. "If 90% of the funds are not returned within 24 hours, tomorrow we will launch a $1M reward for information that leads to your arrest and the return of all funds," the publicly encoded message from Euler Finance said. The reward was publicly announced by the Euler Foundation today.
