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(utxos: Commit, wait: boolean = false, submit: boolean = false): Promise<any>

Parameters

• utxos: A Commit object specifying the UTxOs to be decommitted.
• wait: An optional boolean indicating whether to wait for the decommit to complete. Defaults to false.
• submit: An optional boolean indicating whether to submit the transaction to the chain. Defaults to false.

Returns

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

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 utxosToDecommit = {
    utxos: [
      {
        txIn: "yourTxHash#0", // Replace with a valid UTxO from the head
        value: {
          lovelace: "500000", // 0.5 ADA
        },
      },
    ],
  };

  try {
    console.log("Decommitting UTxOs...");
    const result = await hydra.decommit(utxosToDecommit, true, true); // Wait and submit
    console.log("Decommit result:", result);
  } catch (error) {
    console.error("Error decommitting UTxOs:", error);
  }
}

main();
