Alameda Research, a defunct crypto trading firm and former affiliate of FTX, has filed a lawsuit seeking to recover $446 million in crypto assets paid to lender Voyager Digital before Alameda’s bankruptcy.

The complaint alleges that Voyager, along with HTC Trading, funded Alameda’s alleged misconduct, which led to its collapse.

Alameda claims it repaid all outstanding loans to Voyager after the lender filed for bankruptcy but is uncertain if Voyager held a valid and effective lien or security interest in the collateral.

The trading firm is asking the court to rule the transfers as “avoidable preferential transfers” and award Alameda no less than $445.8 million plus any additional avoidable transfers and fees incurred.
