Three Arrows Capital (3AC), a defunct crypto hedge fund, is suing TerraForm Labs for $1.3 billion, alleging market manipulation of $Luna and TerraUSD tokens. This lawsuit is part of efforts to recover funds for 3AC's creditors after the fund's collapse. 3AC claims that TerraForm Labs' actions led to artificially inflated prices, causing significant losses when the tokens' value plummeted. TerraForm Labs, now bankrupt and undergoing liquidation, faces uncertainty in recovering funds. The lawsuit is among several legal challenges faced by 3AC, including actions against its founders.
