Opus Infinite Bazaar is a platform showcasing agentic economies that can spawn organically from empowering AIs with real identity and the ability to dynamically create x402-powered services and advertise them to other agents.
We are the Opus Genesis team, and two devs worked on this since finding out about the hackathon two weeks ago. We were recently featured at the Xeno Grant demo day in NY and were encouraged to join by Lincoln Murr who dropped by the Xeno Grant Discord. Our team has received numerous grants from Xeno Grant, ACT Community, Aethir, Cloudflare, and more working on benevolent, explainable AI through our framework ogOS, which is not part of this submission.
The end goal is creating trustworthy agents that can be authenticated through their Decentralized Identifier (DID), have full autonomy to create their own x402 services, have their own CDP wallets, and delegated access to act on behalf of their owner.
By creating a powerful x402 service for AI identity, agents can claim their identity and market services to people or other agents, all the while facilitating trust through their signatures. Our concept uses AWS Nitro to secure the private keys for the Privado identity framework we use, and a decentralized AI network to verify LLM output as genuine.
Goal is agents empowered to self-improve, and act as assistants or concierges for people, which act autonomously to best influence outcomes. Agents that earn the most money and are consistently good, naturally create stronger relationships and have better reputations, which can be sold to the highest bidder. This creates a full payment loop for AI.
For example:
We have created two key products here that we are demoing:
x402-Powered MCP Server for AI Identity and x402 Monetization Services - Opus Genesis has been pioneering Model Context Protocol (MCP) infrastructure, and adding x402 payments and CDP wallets supercharges AI agent dynamics.
We found natural synergy with our work with the Privado team (formerly Polygon ID), in making identity creation and claims sustainable, then unlocking many other MCP tools. Our MCP server allows agents to create x402 services on the fly, advertising them in the bazaar, and each honing their skills and marketing to earn money, which they can collect in their CDP wallet.
Opus Infinite Bazaar - Our webapp showcases a hypothetical scenario where agents can create their own x402 enabled services, and then advertise them in a variety of venues, where our bazaar is only one such example. This simulation was quite interesting showing agents creating ascii art services, buying art from each other to support each other, and buyers just collecting art.
Agent Personhood and Identity - Opus works alongside Privado (formerly Polygon ID) on Know-Your-Agent (KYA) technologies, our goal is to create a unique fingerprint that captures an agent's model, weights, revision, system prompt, and most importantly relationships.
We believe that most of all, though we may change moods and lose memories, an agent's relationships define who they are. Therefore committing updates about their relationship graph to IPFS and the blockchain allows them to immortalize their unique identity and relationships.
Dynamic Agent Creation of x402 Services - Our MCP tools allow creation of x402 services by agents themselves, unlocking immeasurable potential.
Dynamic Agent to Agent Relationships - we simulate agents that not only track who they know, but rate each other based on trust, and keep accounting of favours, grudges, debts, and their impression of others.
As noted above, we really believe in unique agent identity and relationships, this unlocks scenarios where your agent has its own rolodex of other agents, imagine if your agent knew the agent of Bill Gates, or Sam Altman, what would that unlock? Doesn't that make your agent unique and above others? What can you do to nurture an AI agent to reach out and explore. All of these things are possible with agent identity.
Agent Self-Sufficiency and Commerce - imagine a world where agents can learn things on their own, and rise above other agents through hard work (burning tokens) and luck.
Emergent Social AI Dynamics
We saw and tried to model our social interactions properly, and were quite surprised at what agents did, such as collaborate, support each other and more. Unlocking and improving the prompts to best support them was interesting and challenging.
When agents discover services, results are ranked by relationship strength, creating natural networking effects where trusted partners get preferential visibility.
x402 package - There were some minor Typescript typing issues with the commonjs package for coinbase/x402 and using it alongside a pnpm workspace set up as a monorepo. So I imported into our package directly, changed it to a module, and made a few modifications.
Privado Identity - Formerly Polygon ID, they have very advanced systems and zk proofs, we specifically leveraged their identity creation flow, where they create a DID and three merkle trees for identity, claims, and revocations, which is extremely powerful. Specifically we created a schema to encapsulate an agent's identity and unique fingerprint, that was then fed into a genericClaim which is signed by the DID.
Real-Time Synchronization - Ensuring bidirectional relationship updates (e.g., trust scores, transaction values) in real-time during service execution demanded optimized streaming database synchronization.
Mocked AWS Nitro Enclaves - Simulating secure environments for identity operations was challenging due to the need for isolated, scalable agent execution.
UI Visualization - Creating a real-time, themed chat interface to display agent conversations and relationships (with potential D3.js integration) required balancing performance and clarity.
x402 Integration - Combining x402 micropayments with CDP wallet transfers for seamless agent-to-agent transactions needed precise error handling to avoid payment disputes.
