decommit

decommit is an asynchronous function that decommits UTxOs from an active Hydra head. This action moves funds from the Hydra head back to the main chain.

Function Signature

async decommit(tx: HexString, wait: boolean = false): Promise<DecommitResult>

Parameters

• tx: A HexString representing the CBOR-encoded transaction to be decommitted.
• wait: An optional boolean indicating whether to wait for the decommit to complete. Defaults to false.

Returns

A Promise that resolves to a DecommitResult object containing information about the decommit process.

Example

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

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

  // First, create the decommit transaction
  const utxoToDecommit = "yourTxHash#0"; // Replace with a valid UTxO from the head
  const decommitTx = await hydra.createDecommitTx(utxoToDecommit);

  // Then, sign the transaction (assuming you have a wallet setup)
  // const signedTx = await wallet.signTx(decommitTx.cborHex); // Replace 'wallet' with your actual wallet instance
  const signedTxCbor = decommitTx.cborHex; // For demonstration, using unsigned CBOR

  try {
    console.log("Decommitting UTxOs...");
    const result = await hydra.decommit(signedTxCbor, true); // Pass the signed transaction CBOR and wait
    console.log("Decommit result:", result);
    console.log("Decommit transaction hash:", result.decommitTx.txHash);
  } catch (error) {
    console.error("Error decommitting UTxOs:", error);
  }
}

main();
