Sign and Execute Transaction

The signAndExecuteTransaction action prompts the connected wallet to sign and immediately execute a transaction on the Sui network. This is the most common way to execute transactions in your dApp.

Usage

import { createDAppKit } from '@mysten/dapp-kit-core';
import { Transaction, coinWithBalance } from '@mysten/sui/transactions';

const dAppKit = createDAppKit({
	/* config */
});

const tx = new Transaction();
// No need to manually set sender - it's done automatically
tx.transferObjects([coinWithBalance({ balance: 123 })], '0xrecipient...');

const result = await dAppKit.signAndExecuteTransaction({
	transaction: tx,
});

if (result.FailedTransaction) {
	throw new Error(`Transaction failed: ${result.FailedTransaction.status.error?.message}`);
}

console.log('Transaction digest:', result.Transaction.digest);

Parameters

• transaction - Transaction | string - The transaction to sign and execute. Can be either a Transaction instance or base64-encoded bcs bytes for the transaction.
• signal (optional) - AbortSignal - An abort signal to cancel the transaction request.

Return Value

Returns a Promise that resolves to a TransactionResult discriminated union:

type TransactionResult =
	| { $kind: 'Transaction'; Transaction: Transaction }
	| { $kind: 'FailedTransaction'; FailedTransaction: Transaction };

The Transaction object contains:

• digest - string - The transaction digest (unique identifier for the executed transaction)
• signatures - string[] - The signatures as base64-encoded strings
• epoch - string | null - The epoch in which the transaction was executed
• status - ExecutionStatus - The execution status with success: boolean and error: string | null
• effects - TransactionEffects | null - The parsed transaction effects (may be null if effects parsing fails for unknown effect versions)
• transaction - TransactionData - The parsed transaction data

const result = await dAppKit.signAndExecuteTransaction({ transaction });

if (result.FailedTransaction) {
	console.error('Transaction failed:', result.FailedTransaction.status.error?.message);
	return;
}

// Access the successful transaction results
const tx = result.Transaction;
console.log('Digest:', tx.digest);
console.log('Signatures:', tx.signatures);
console.log('Epoch:', tx.epoch);

Transaction Building

When passing a Transaction instance, the action automatically:

1. Sets the sender address if not already set
2. Builds the transaction using the current network's client
3. Converts it to the appropriate format for the wallet
4. Submits the transaction to the network

Wallet Compatibility

• The action transparently handles both sui:signAndExecuteTransaction and sui:signAndExecuteTransactionBlock wallet-standard features
• The wallet handles network submission and response
• Some wallets (Enoki, Enoki Connect, WalletConnect) may use the dApp Kit client and execute transactions within the application as an implementation detail

// The action automatically detects and uses the appropriate method
// No special configuration needed
const result = await dAppKit.signAndExecuteTransaction({
	transaction: tx,
});
