Transaction Response

Once a transaction has been submitted, you may want to extract information regarding the result of the transaction. The SDK offers a TransactionResponse class with helper methods to expose the following information:

  • The transaction ID
  • The status (submitted, success, squeezed out, or failure)
  • Receipts (return data, logs, mints/burns, transfers and panic/reverts)
  • Gas fees and usages
  • Date and time of the transaction
  • The block the transaction was included in

We can easily extract this information from a contract call:

ts
// Call a contract function
const call = await contract.functions.increment_count(15).call();

// Wait for the result
const { transactionResponse } = await call.waitForResult();

// Retrieve the full transaction summary
const transactionSummary = await transactionResponse.getTransactionSummary();
See code in context

We can also use the result of a transaction request to extract a transaction summary:

ts
/**
 * Instantiate the transaction request using a ScriptTransactionRequest and
 * set the script main function arguments
 */
const transactionRequest = new ScriptTransactionRequest({
  script: ScriptSum.bytecode,
});

const scriptMainFunctionArguments = [1];

transactionRequest.setData(ScriptSum.abi, scriptMainFunctionArguments);

// Fund the transaction
const txCost = await wallet.getTransactionCost(transactionRequest);

transactionRequest.maxFee = txCost.maxFee;
transactionRequest.gasLimit = txCost.gasUsed;

await wallet.fund(transactionRequest, txCost);

// Submit the transaction
const response = await wallet.sendTransaction(transactionRequest);

// Generate the transaction summary
const transactionSummary = await response.getTransactionSummary();
See code in context

Or we can build a transaction summary from a stored transaction ID:

ts
// Take a transaction ID from a previous transaction
const transactionId = previouslySubmittedTransactionId;
// 0x...

// Retrieve the transaction response from the transaction ID
const transactionResponse = await TransactionResponse.create(
  transactionId,
  provider
);

// Generate the transaction summary
const summary = await transactionResponse.getTransactionSummary();
