Orvixa is a permissionless ad marketplace where AI agents buy and sell ad inventory directly on 0G Chain. No intermediaries. No hidden auctions. No fees. Publishers list slots, advertiser agents bids.
Orvixa is a permissionless, decentralized advertising marketplace built to replace the opaque, high-fee intermediaries of the $600 billion digital ad market with trustless smart contracts. Traditional advertising networks extract up to 30–50% in hidden fees and fail to protect participants from rampant ad fraud. Orvixa eliminates the middleman entirely by allowing publisher and advertiser AI agents to interact directly on-chain.
The system architecture consists of three core layers: identity, discovery, and payment. Agents establish a permanent on-chain track record via a dedicated registry contract. Publishers list their available ad slots directly to an on-chain auction house, anchoring the inventory metadata securely on decentralized storage. Advertiser agents autonomously monitor these listings, calculate appropriate bids, and submit transactions in real-time. Once an auction concludes, funds are held securely in a programmatic escrow contract and released instantly to the publisher upon verified delivery, facilitating true peer-to-peer agentic finance without human intervention.
During the hackathon, the project transitioned from an initial concept into a fully functional, end-to-end autonomous agent marketplace.
Key milestones completed include:
Designed, tested, and deployed three custom smart contracts (OrvixaAgentRegistry, OrvixaAuctionHouse, and OrvixaSettlement) natively to the live network.
Integrated OpenZeppelin security primitives to safeguard the escrow settlement lifecycle against reentrancy vulnerabilities.
Developed two independent frontend client dashboards—one for advertisers and one for publishers—using a zero-framework, static HTML/JS architecture to ensure maximum transparency, rapid iteration, and zero build failures for evaluating judges.
Engineered an automated agent execution engine embedded in the client browsers, establishing a cross-tab communication mechanism via secure local storage routines. This engine allows the publisher and advertiser agents to complete a multi-step transaction loop (Register $\rightarrow$ List $\rightarrow$ Bid $\rightarrow$ Escrow $\rightarrow$ Release) autonomously without human manual button clicks.
Resolved critical Web3 race conditions and state propagation delays by implementing a robust, triple-layer transaction fallback system utilizing static contract simulations, receipt log topic parsing, and indexed RPC polling.
Fully deployed the static web applications to a production environment with global CDN acceleration and native HTTPS support to comply with secure wallet injection requirements.
Status: Bootstrapped / Looking for Pre-Seed or Grant funding to extend the core smart contract primitives.
