hi @Seanxwy

for get balance of wallet you must use this code :

            IServiceCollection services = new ServiceCollection();
            services.AddTronDotNetCore(x =>
            {
                x.Network = TronDotNetCorework.MainNet;
                x.Channel = new GrpcChannelOption { Host = "47.252.19.181", Port = 50051 };
                x.SolidityChannel = new GrpcChannelOption { Host = "47.252.19.181", Port = 50052 };
                x.ApiKey = "api-code"; //https://www.trongrid.io
            });
            services.AddLogging();

            var service = services.BuildServiceProvider();
            var walletClient = service.GetService<IWalletClient>();

            var account = walletClient.GetAccount(privatekey);

            //USDT TOKEN
            var contractAddress = "TXLAQ63Xg1NAzckPwKHvzw7CSEmLMEqcdj";


            var contractClientFactory = service.GetService<IContractClientFactory>();

            var contractClient = contractClientFactory.CreateClient(ContractProtocol.TRC20);

            var result = contractClient.BalanceOfAsync(contractAddress, account).Result;

你說的事件是指錢包發生有入帳的事件嗎?
如果是這樣你不是節點應該是無法，你要一直去監聽
除非你是節點，節點就會有自己的事件

不是节点，使用定时监听的方式也应该可以达成需求吧。

對阿 簡單的說就是你要一直去查
