1inch was subjected to a hacker attack, losing more than $5 million due to a vulnerability in the smart contract, but user funds remained safe

1inch became the victim of a hacker attack, in which more than $5 million was stolen. The hackers exploited a vulnerability in the Fusion v1 smart contract, affecting the resolvers responsible for executing orders on the platform. However, user funds were not affected as the damage was limited to the resolver contract. In response to the attack, 1inch began cooperating with the affected parties, updated its smart contracts, and launched a bug bounty program to improve the platform's security.
