Crypto lending firm Celsius, which went bankrupt last year, is suing liquid staking platform StakeHound, accusing it of failing to return $150 million worth of ETH, MATIC, DOT and other tokens. According to court documents, Celsius commissioned StakeHound to pledge 60,000 ETH, 40 million MATIC, and 66,000 DOT in 2021. According to a court document filed with the U.S. Bankruptcy Court for the Southern District of New York, StakeHound filed an arbitration agreement against Celsius in Switzerland after Celsius went bankrupt. Said that 35,000 keys related to Celsius ETH were lost and was relieved of the obligation to return these tokens.
