Syntax

public sealed class ExternalTransactionParams : TransactionParams<TransactionReceipt>

Examples

Relay a pre-built signed transaction, adding an extra signatory through the params object without reconstructing the body bytes:

// Use the params overload to layer additional signatures on top of
// an externally-signed transaction without re-building the body.
// Any Signatory in the client's context is also applied.
var receipt = await client.SubmitExternalTransactionAsync(new ExternalTransactionParams
{
    SignedTransactionBytes = signedBytes,
    Signatory = extraSignatory
});
Console.WriteLine($"Status: {receipt.Status}");
