module Glueby

    # This class can send TPC between wallets.
    #
    # Examples:
    #
    # sender = Glueby::Wallet.load("wallet_id")
    # receiver = Glueby::Wallet.load("wallet_id")
    #                      or
    #            Glueby::Wallet.create
    #
    # Use `Glueby::Internal::Wallet#receive_address` to generate the address of a receiver
    # receiver.internal_wallet.receive_address
    # => '1CY6TSSARn8rAFD9chCghX5B7j4PKR8S1a'
    #
    # Balance of sender and receiver before send
    # sender.balances[""]
    # => 100_000(tapyrus)
    # receiver.balances[""]
    # => 0(tapyrus)
    #
    # Send
    # Payment.transfer(sender: sender, receiver_address: '1CY6TSSARn8rAFD9chCghX5B7j4PKR8S1a', amount: 10_000)
    # sender.balances[""]
    # => 90_000
    # receiver.balances[""]
    # => 10_000
    #
