choose/switch to BOS wallet
Click【Import BOS account】，copy and paste the account private key of the EOS account
! ! Note: Although the private key is the same, the 【account name】 is modified when the BOS starts the mapping, so the account you see after importing is different from the EOS.
After the import is completed, the BOS wallet can be operated. The basic functions is almost the same as EOS.
