I registered an account name on EOS mainnet and I have
cleos and other tools installed locally. How can I add/delete/change private keys and transfer EOS tokens to other accounts?
Description of adding/changing private keys is available here. To transfer EOS tokens using cleos, use:
cleos -u <RPC API URL> transfer <sender account name> <recipient account name> '<EOS amount> EOS' <[optional] memo>
cleos -u https://api.tokenika.io transfer aaaaaaaaaaaa bbbbbbbbbbbb '1 EOS'
