+
+| Method | Description | How to test | Test Result |

+| decimals | see nep-5 | neo-gui | ✅ |

+| transfer | see nep-5 | neo-gui or neo-cli | ✅ |
+| transferAPP | transfer from other smart contract | neo-gui + other smart contract | ✅ |
+| TriggerType.Verification | | c# code + neo-cli | ✅ |
+
+Useful Test Tools: [https://github.com/chenzhitong/ApplicationLogsTools](https://github.com/chenzhitong/ApplicationLogsTools)
+
+备注:
+
+Verification 触发器执行时如果有参数需要传参,否则会因为栈不平而失败
+
+Verification 触发器的参数要放在交易的 Witness 的 InvocationScript 字段中,可以用 ScriptBuilder 来构造
+
+Verification 触发器中不能执行下面的代码
+var callscript = ExecutionEngine.CallingScriptHash;
+
+未部署的合约不能执行 Storage.Get() 方法
+
+Storage.Get() 如果查询不到的话,返回 byte[0] 而不是 null
+
+Application 触发器中如果调用 CheckWitness() 的话,需要在 TransactionAttribute 中传附加人的签名 Usage = TransactionAttributeUsage.Script Data = ScriptHash,并且在 Scripts 中添加一个新的 Witness
+
+推荐使用 StorageMap 来读写存储区,而不是直接用 Storage.Get 或 Storage.Put
+
+NEP-5 中,参数错误应该抛出异常,而不是返回 false
