Я ищу способ перевести все остатки из Ethreuem и других его токенов. Для ETH я могу оценить gas и gasPrice, используя следующий код:

var wallet = new Wallet(Words, Password);
            var account = wallet.GetAccount(0);
            var web3 = new Web3(account);
            var balanceRes = web3.Eth.GetBalance.SendRequestAsync(account.Address, new BlockParameter(new HexBigInteger(9349220))).GetAwaiter().GetResult();
            var balance = Web3.Convert.FromWei(BigInteger.Parse(balanceRes.ToString()));
            var gas = web3.Eth.GetEtherTransferService().EstimateGasAsync("To address", balance).GetAwaiter().GetResult();
            var gasprice = web3.Eth.GasPrice.SendRequestAsync().GetAwaiter().GetResult().Value;
            var tmp = gas * gasprice;
            var fee = Web3.Convert.FromWei(tmp);
            var amount = balance - fee;
            var transaction = web3.Eth.GetEtherTransferService().TransferEtherAndWaitForReceiptAsync("To address", amount).GetAwaiter().GetResult();

Проблема возникает, когда я хочу сделать то же самое с токенами. Вот пример с токеном USDT, который не работает должным образом:

var wallet = new Wallet(Words, Password);
            var account = wallet.GetAccount(0);
            var web3 = new Web3(account);
            var gasprice = web3.Eth.GasPrice.SendRequestAsync().GetAwaiter().GetResult();
            var contractByteCode = "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";
