現在の公開鍵と秘密鍵の取得

公開鍵に基づいて、既存のアカウントを表示

feng@feng-B250-HD3P:~/workSpace/eos/build/programs/cleos$ ./cleos get accounts EOS5a7fk4RAQ2fzdWy5TTRdhmcHpZQxwyoLqvczQHhpcGSjoFdSkK
{
  "account_names": [
    "eosio.token",
    "ex",
    "tester",
    "user"
  ]
}

契約ファイルの生成:
自分でbuild/contracts/ディレクトリの下にhelloフォルダとhello/hellolloを作成します.cppファイル

#include 
#include 
using namespace eosio;

class hello : public eosio::contract {
  public:
      using contract::contract;

      /// @abi action 
      void hi( account_name user ) {
         print( "Hello, ", name{user} );
      }
};

EOSIO_ABI( hello, (hi) )

wastファイルとabiファイルの生成
