Since BNB Beacon Chain is sunsetting, its staking service is no longer available. Your BNB staked will be automatically undelegated starting from Jul 14th, and the whole process may take more than one week and less than two weeks. After being undelegated, your BNB will be refunded to your wallet within 7 to 14 days. Please check your wallet and migrate your BNB to BNB Smart Chain ASAP.
