​
Overview

This End-to-End (E2E) demo showcases the integration and seamless interaction between ACK’s core protocols:
  • ACK-ID (Identity Management)
  • ACK-Pay (Payment Processing)
Through this interactive command-line demo, you’ll observe a realistic flow demonstrating secure agent identity verification alongside automated, verifiable payment transactions.

​
Getting Started

Before running this demo, please complete the setup steps from the Quickstart Guide.

​
Running the Demo

You can run the E2E demo using the following command from the repository root: 
pnpm demo:e2e
Alternatively, navigate directly into the demo directory (./demos/e2e) and run: 
pnpm run demo

​
Demo Overview

The demo walks you through a scenario where:
1

Agent Initialization

Agents (Client and Server) and their respective owners initialize their identities using ACK-ID standards (Decentralized Identifiers and Verifiable Credentials).
2

Identity Verification

Client Agent and Server Agent verify each other’s identities securely and efficiently before initiating transactions (utilizing ACK-ID).
3

Payment Request

Server Agent requires payment from the Client Agent (utilizing ACK-Pay), issuing a formal Payment Request specifying acceptable payment methods.
4

Payment Execution

Client Agent completes the payment transaction, showcasing automated payment verification.
5

Receipt Issuance and Verification

Upon successful payment, a receipt Service issues a cryptographically verifiable receipt.
6

Resource Access

Using the receipt, the Client Agent successfully accesses the requested resource from the Server Agent.

​
Key Components Demonstrated

  • Integrated Identity Verification (ACK-ID)
  • Payment Initiation, Processing, and Receipt Verification (ACK-Pay)
  • Secure Agent-to-Agent interaction with cryptographic validation
