  <br>

  **1. Key Components**

  • Trikon Bundler: Functions as a validator, fetching transactions from the mempool and executing them via the Entrypoint contract.

  • Entrypoint Contract: A pre-deployed contract across all networks for handling transactions.

  • Verifying Paymaster Contract: Facilitates gas payment and sponsorship for user transactions.

  • Smart-Wallet-Factory Contract: Streamlines wallet creation for users, ensuring a smooth gaming experience.

  <br>

  **2. Configuration Steps**

  1\. Ensure the Trikon Bundler is operational on the designated blockchain network.

  2\. Deploy the Entrypoint Contract to handle transaction execution.

  3\. Deploy the Verifying Paymaster Contract for gas fee sponsorship.

  4\. Set up the Smart-Wallet-Factory Contract to simplify wallet creation.

  5\. Configure paymaster policies via the Paymaster UI, tailoring gas fee sponsorship to project needs .\
