FTX Trust, the legal entity overseeing asset recovery for creditors in the bankruptcy of the FTX cryptocurrency exchange, filed a $1.15 billion lawsuit against Genesis Digital Assets today. The suit targets the major Bitcoin mining company over alleged fraudulent transfers.

The lawsuit represents one of the largest clawback efforts in the FTX bankruptcy proceedings. Under U.S. bankruptcy laws, the trust can pursue “avoidance actions” to recover funds transferred fraudulently before bankruptcy.

Genesis Digital received over $1 billion in investments from Alameda Research in 2021-2022, making it one of the largest assets in the FTX bankruptcy case. Alameda Research was a quantitative trading firm closely tied to FTX.

The FTX collapse in late 2022 led to over $8 billion in missing customer funds, triggering numerous lawsuits and recovery efforts. The exchange filed for bankruptcy amid fraud allegations against its leadership.
