Committing UTxOs

Once the Hydra head is initialized, both participating parties must submit their commitments. To do this, define a commit object specifying the UTxOs to be included. If a signing key is provided, the Kuber-Hydra server will generate a signed transaction that can be submitted to the blockchain. The submit parameter determines the desired behavior—set it to true to submit the transaction immediately, or false to receive an unsigned transaction for manual submission later.

const commitment: Commit = {
  utxos: [
    "4051dd270c1a51da8645b6c91d23053273547f1f853929fbec5519527e18266d#13",
  ],
  signKey: {
    type: "PaymentSigningKeyShelley_ed25519",
    description: "Payment Signing Key",
    cborHex:
      "5820def9b27d28b25a28156e42a57e1a81d5412517ba2f73784bb230c676dd0d9d65",
  },
};
const commitResponse = await hydraService.commit(commitment, true);
console.log(commitResponse);

On success, you will receive a Witnessed Tx in CBOR format.
