Dear HALO community, In order to expand HALO Chain to be more suitable for the smooth operation of applications, self-built auxiliary nodes and node update and upgrade will be carried out for some applications, which is expected to be completed within 3–4 working days. During the upgrade period, it is expected that transfers and some applications cannot be packaged and put on the chain. We apologize for the inconvenience it may cause. We appreciate your patience and understanding.
