buildTx

buildTx is an asynchronous function that constructs a transaction within the Hydra head. This function allows you to define outputs and other transaction parameters for off-chain transactions.

Function Signature

async buildTx(tx: any, submit: boolean = false): Promise<CommonTxObject>

Parameters

• tx: An object representing the transaction to be built. This object should conform to the expected transaction structure for Hydra. For a comprehensive reference on transaction builder fields and their usage, please refer to the KuberIDE TxBuilder Object Reference.
• submit: An optional boolean indicating whether to submit the transaction to the head. Defaults to false.

Returns

A Promise that resolves to a CommonTxObject representing the built transaction.

Example

const { loadCrypto } = require("libcardano");
const { KuberHydraApiProvider } = require("kuber-client");

async function main() {
  await loadCrypto();

  const hydra = new KuberHydraApiProvider("http://localhost:8081"); // Replace with your Hydra API URL

  const transaction = {
    outputs: [
      {
        address: "addr_test1qr...", // Recipient address
        value: {
          lovelace: "500000", // 0.5 ADA
        },
      },
    ],
    // Add other transaction parameters as needed, e.g., inputs, metadata
  };

  try {
    console.log("Building transaction...");
    const builtTx = await hydra.buildTx(transaction, true); // Submit the transaction
    console.log("Built transaction:", builtTx);
  } catch (error) {
    console.error("Error building transaction:", error);
  }
}

main();
