Dear BitMart Users,   Due to the service upgrade, the deposit and withdrawal features of POLYGON chain and related tokens are temporarily suspended. Please be patient and keep an eye on our announcements for further updates. Thank you for your support and understanding!   Note: After the upgrade is completed, the deposit address for POLYGON chain and related tokens will be changed, and the previous deposit address is still working and will be unavailable after one month.   BitMart Team Nov. 24, 2021
