5、查看合约: https://testnet.bscscan.com/ 输入合约地址

6、blockchain资料: https://benpaodewoniu.github.io/categories/%E5%8C%BA%E5%9D%97%E9%93%BE/page/3/

7、转账测试
crawsun@manka-d-l-5110 ERC20FixedSupply % truffle console --network testnet
truffle(testnet)> ERC20FixedSupply.deployed().then(function(instance){return instance.transfer('0x058A5c347171Dd0d1bE3F21269FD1366Fe49dEE6', '10000');})
注意这里amount要写成字符串，否则数字会溢出，实际转账金额要/decimal(默认是18)
ERC20FixedSupply.deployed().then(function(instance){return instance.transfer('0x30B1DeFB55e442c926732574b9cBCDeFa5a7eC48', '10000000000000000000000');})

从合约地址转账到钱包, todo test
ERC20FixedSupply.deployed().then(function(instance){return instance.transferFrom('0xcA9D8EB62F06CDb7F781FC5a37304BBE892ef701', '0x30B1DeFB55e442c926732574b9cBCDeFa5a7eC48', '1000000000000000000000');}))
