Celsius Network LLC, a bankrupt cryptocurrency firm, has agreed to sell its lending platform to NovaWulf Digital Management LP as part of a plan to distribute its coins and other assets to customers. If accepted by a majority of Celsius customers and approved by the bankruptcy court, the proposed deal would provide a way out for users whose digital assets worth billions of dollars have been frozen on the platform since July. Last year, the crypto firm declared bankruptcy with a $1.2 billion hole in its balance sheet, with digital assets owed to retail customers accounting for the majority of its liabilities.
