BlockFills, a CME-backed cryptocurrency trading and lending platform, has suspended customer withdrawals and deposits as it works to restore liquidity. The company announced that the suspension, which began last week, aims to protect both customers and the firm. Trading services remain available under certain conditions, but no timeline has been provided for resuming withdrawals. BlockFills, which serves institutions and high-net-worth clients, is collaborating with investors and customers to address the liquidity issues. The management has not confirmed the safety of customer assets or the possibility of full repayment once withdrawals resume. The platform's investors include CME Group's venture capital arm and Susquehanna Private Equity Investments.
