Filament Finance reported the hack lasted four hours, between 12:00 AM UTC and 4:00 AM UTC on April 6. The DEX platform also noted it had about $680,000 in total user deposits before the compromise, implying that the exchange was left with $108,000 after the exploit.

Recovery Efforts

In its tweet, Filament Finance outlined its fund recovery efforts. First, the DEX platform secured its protocol by halting trading operations and withdrawals. Secondly, it reached out to leading blockchain forensic firms and DeFi partners to investigate the hack.
