问题
在我使用WatchBlockEvent()订阅方法时出现了以下错误：
对应源码:
tips: 报红是我导包出错得问题,不影响本问题
个人建议
监听方法当出现错误时支持重连逻辑
support GM
update the version of the dependency of xchain
建议：SetContractAccount方法不要限制16位，因为要传以太坊地址
account包的SetContractAccount方法，下图逻辑限制了16位，但是某些场景需要传入以太坊地址，由于该字段未export，所以在包外又无法修改
比如下图合约：
mint方法需要校验合约账户是否为owner，此时需要传入eth的40位地址，而不是xuper的16位地址
合约查询，返回结果与cli命令结果不一致
solidity代码如下：
// SPDX-License-Identifier: MIT

}
function _beforeTokenTransfer(address from, address to, uint256 amount)

override

super._beforeTokenTransfer(from, to, amount);
}
}
当我执行继承自openzeppelin包的方法时，如果xuperIDE调试，结果如下：
如果用cli调用，也是一致的
唯独在调用sdk时，返回结果不一致，是一串代码
返回的结果是这样的
请问如何才能取到正确的返回数据？
合约调用错误问题

合约event问题
请问：
1.调用合约返回信息中没有eventlog，那有办法在不使用订阅的情况下知道此次交易是否有eventlog吗？
2.我想同步非挖矿的交易信息，如果使用订阅所有块，返回的信息中只有交易hash，并不能区分出这个交易是出块奖励还是正常的交易，这个有办法吗？
没有evm合约升级方法
请问有evm合约升级方法吗,我看sdk中只提供了native和wasm合约升级方法,另外通过解读源码发现,提示说关闭了evm升级,不知为何？

功能建议：增加一个xuper地址和evm地址转换的接口
在利用solidity语言开发是，如ERC20、ERC721等，参数会经常传入以太坊0x的40位地址，这与xuper的16位地址不相同。
目前我是通过cli的形式在转换，既然cli已经支持，为什么sdk不加入该接口呢？

在使用sdk有这样的场景,有人部署了一个native go得合约,或者我忘记了，现在我想调用这个合约，但是我不知道这个合约是什么类型，现在我用别得类型比如InvokeEVMContract() 方法去调用这个go合约就会出错，请问我如何能拿到合约module类型，如果没有可否考虑在QueryAddressContracts()方法或者QueryAccountContracts()方法中进行扩展？

我想通过TxId查询判断当前这一笔交易有没有上链,但QueryTxByID()没有返回相关状态值。看下代码,貌似是有实现的但是并没有暴露出来。
QueryTx方法返回的是TxStatus结构体对象
对应的枚举值
不知道我的猜想是否正确,有没有什么方案？感谢！

XuperChain使用Go-SDK调用模板合约“文件hash上链时，更改文件hash_id后仍出现”such hash has existed already的报错
image
我在“工作台”中“合约管理”中调用中修改不同的hash_id均成功了，但是在本地调用时修改不同的hash_id出现了such hash has existed already的报错
智能合约中的存证函数如下：
void storeFileInfo() {
xchain::Context* ctx = this->context();
std::string user_id = ctx->arg("user_id");
std::string hash_id = ctx->arg("hash_id");
std::string file_name = ctx->arg("file_name");
const std::string userKey = UserBucket + "/" + user_id + "/" + hash_id;
const std::string hashKey = HashBucket + "/" + hash_id;
std::string value = user_id + "\t" + hash_id + "\t" + file_name;
std::string tempVal;
if (ctx->get_object(hashKey, &tempVal)) {
ctx->error("storeFileInfo failed, such hash has existed already");
return;
}
if (ctx->put_object(userKey, value) && ctx->put_object(hashKey, value)) {
ctx->ok("storeFileInfo success");
return;
}
ctx->error("storeFileInfo failed");
}
后续更新：
去除了智能合约中的唯一性约束代码：
if (ctx->get_object(hashKey, &tempVal)) {
ctx->error("storeFileInfo failed, such hash has existed already");
return;
多次使用不同的hash_id运行成功，两次使用相同的hash_id上链存储也成功运行。但是实际的区块链存证业务场景中要求对存证文件的唯一性约束，请问错误是处在SDK上还是智能合约上？

查询区块Proposer的一些疑问
SDK版本：0.2.0
Xchain 版本：5.1.0
使用Go SDK查询区块的Proposer返回有问题，请问是我解析的有问题还是返回的内容不正确，其他参数(PreHash 等)暂时没问题。
`普通账号`给`合约账号`转账出现：TX_VERIFICATION_ERROR错误
场景：
- 使用的链地址（39.156.69.83:37100）
- 本来想通过SDK部署本地编译的solidity合约到链上，提示
合约账号UTXO不足； - 所以尝试通过
普通账号给合约账号转账一些，结果出现TX_VERIFICATION_ERROR的错误？
这个合约账号是普通账号下的。
请问是什么原因？
