## Sign messages
Sign messages on an external browser.
```cpp theme={null}
const TSuccessCallback SuccessCallback = [OnSuccess](const bool& Result) { };
const FFailureCallback FailureCallback = [OnFailure](const FSequenceError& Error) { };
USequenceWallet* Wallet = NewObject();
Wallet->SignMessage(TEXT("some text"), SuccessCallback, FailureCallback);
```
## Transactions
### Get fee options
```cpp theme={null}
const FString To = TEXT("0x33985d320809E26274a72E03268c8a29927Bc6dA");
const FString Value = TEXT("0");
const FString FunctionSignature = TEXT("explicitEmit()");
const TArray Values = { };
UContractTransaction* Transaction = UContractTransaction::CreateContractTransaction(To, Value, FunctionSignature, Values);
const TSuccessCallback SuccessCallback = [OnSuccess](const FFeeOptionsResponse& Response) { };
const FFailureCallback FailureCallback = [OnFailure](const FSequenceError& Error) { };
USequenceWallet* Wallet = NewObject();
Wallet->GetFeeOptions(Transaction, SuccessCallback, FailureCallback);
```
### Send transactions
```cpp theme={null}
const FString To = TEXT("0x33985d320809E26274a72E03268c8a29927Bc6dA");
const FString Value = TEXT("0");
const FString FunctionSignature = TEXT("explicitEmit()");
const TArray Values = { };
UContractTransaction* Transaction = UContractTransaction::CreateContractTransaction(To, Value, FunctionSignature, Values);
FFeeOption EmptyFee;
const TSuccessCallback SuccessCallback = [OnSuccess](const FString& Result) { };
const FFailureCallback FailureCallback = [OnFailure](const FSequenceError& Error) { };
USequenceWallet* Wallet = NewObject();
Wallet->SendTransaction(Transaction, EmptyFee, SuccessCallback, FailureCallback);
```
### Send transactions without Permissions
Send transactions on an external browser.
```cpp theme={null}
const FString To = TEXT("0x33985d320809E26274a72E03268c8a29927Bc6dA");
const FString Value = TEXT("0");
const FString FunctionSignature = TEXT("explicitEmit()");
const TArray Values = { };
UContractTransaction* Transaction = UContractTransaction::CreateContractTransaction(To, Value, FunctionSignature, Values);
const TSuccessCallback SuccessCallback = [OnSuccess](const FString& Result) { };
const FFailureCallback FailureCallback = [OnFailure](const FSequenceError& Error) { };
USequenceWallet* Wallet = NewObject();
Wallet->SendTransactionWithoutPermissions(Transaction, SuccessCallback, FailureCallback);
```
## Transaction Factory
### Create Contract Transaction
```cpp theme={null}
const FString To = TEXT("0x33985d320809E26274a72E03268c8a29927Bc6dA");
const FString Value = TEXT("0");
const FString FunctionSignature = TEXT("explicitEmit()");
const TArray Values = { };
UContractTransaction* Transaction = UContractTransaction::CreateContractTransaction(To, Value, FunctionSignature, Values);
```
### Create Call Data Transaction
```cpp theme={null}
const FString To = TEXT("0x33985d320809E26274a72E03268c8a29927Bc6dA");
const FString Value = TEXT("0");
const FString Data = TEXT("0x00...");
UCallDataTransaction* Transaction = UCallDataTransaction::CreateCallDataTransaction(To, Value, Data);
```
### Create Transaction Batch
```cpp theme={null}
TArray> Transactions;
Transactions.Add(UCallDataTransaction::CreateCallDataTransaction("0x123...", "0", "0x00.."));
UTransactionBatch* Transaction = UTransactionBatch::CreateTransactionBatch(To, Value, Data);
```
