开始部署
- 下载代码
git clone https://github.com/cppfuns/signdappplay.git - 编译代码
//进入源码目录 cd signdappplay/ //生成abi文件 eosiocpp -g signdappplay.abi signdappplay.cpp //生成wast文件 eosiocpp -o signdappplay.wast signdappplay.cpp - 部署合约
//提前创建好signdappplay 将合约部署到此账号 cleos set contract signdappplay signdappplay/ -p signdappplay - 为
signdappplay@active里添加signdappplay@eosio.code授权cleos set account permission signdappplay active '{"threshold": 1,"keys": [{"key": "EOS7nK2w6ZT8hKdrxr48xdt3CFj1MXpaDV6jagRHKayFhqJBX5GEf","weight": 1}],"accounts": [{"permission":{"actor":"signdappplay","permission":"eosio.code"},"weight":1}]}' owner -p signdappplay
开始转账创建账号
向signdappplay账号转账，并按规则（新建账户名:owner公钥:active公钥）填写memo。（分隔符支持"-" ":"或者空格，如果owner公钥与active公钥一致，可以只填写一个，如实例）。

warning: transaction executed locally, but may not be confirmed by the network yet账户向signdappplay账号转一定量的EOS，合约将会自动创建新账户，为CPU和NET各抵押0.1EOS，剩余EOS全部为新账户购买RAM（0.5%手续费）。
