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
See code in context// 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();
We can also use the result of a transaction request to extract a transaction summary:
ts
See code in context/**
* 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();
Or we can build a transaction summary from a stored transaction ID:
ts
See code in context// 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();
