Joy Marketplace

What is Joy? Joy is more than a marketplace. Joy is a new way for people to participate in the future of AI. Right now, artificial intelligence is being shaped by a small number of powerful companies. They control the models, the data, the infrastructure, and the value being created. But we believe the future of AI should belong to the people building it, using it, improving it, and being impacted by it. That is why we are building Joy. Joy is a people-powered AI marketplace where developers, creators, researchers, businesses, and communities can come together to build, share, protect, license, and monetize AI agents, models, datasets, tools, and digital intelligence. It is a place where creators can turn their knowledge into assets. A place where businesses can discover trusted AI solutions. A place where communities can help guide what technology becomes. And a place where ownership, transparency, collaboration, and purpose are built into the foundation. Joy uses Web3, blockchain, smart contracts, and decentralized infrastructure to create a more open and fair AI economy — one where people can prove ownership, protect what they build, earn from their contributions, and participate in the growth of the ecosystem. But Joy is not just about technology. Joy is about restoring the human side of innovation. It is about making sure AI serves people, not the other way around. It is about creating opportunity instead of extraction. It is about building a future where intelligence becomes accessible, creativity becomes valuable, and technology becomes a tool for shared prosperity. Joy is built for creators. Built for builders. Built for businesses. Built for communities. Built for the people who believe the future of AI should be open, ethical, useful, and joyful. Welcome to Joy.

Description

Joy Marketplace is a people-powered marketplace for the next generation of AI.

We are entering a world where artificial intelligence will shape nearly every part of life: how we work, learn, build, create, govern, heal, communicate, and solve problems. But right now, the future of AI is being built inside fragmented and centralized systems. Access is expensive. Ownership is unclear. Trust is hard to verify. Creators struggle to protect and monetize what they build. Businesses struggle to find reliable AI tools without hiring entire engineering teams. Communities are left consuming AI instead of owning, shaping, and benefiting from it.

Joy Marketplace exists to change that.

Joy Marketplace is a decentralized Web3 marketplace where AI models, agents, datasets, workflows, automations, skills, prompts, tools, and digital assets can be protected, published, discovered, licensed, deployed, and monetized. It gives creators a place to turn their intelligence into income. It gives businesses a trusted place to find and use AI solutions. It gives communities a way to participate in the AI economy instead of being left behind by it.

The vision is simple but massive:

Joy Marketplace is becoming the Amazon marketplace for AI.

But unlike the old platform economy, JoyMarketplace is not built to trap creators, extract value, or centralize control. It is built to return ownership to the people who create. It uses blockchain-backed proof of ownership, smart contracts, tokenized assets, secure licensing, transparent transactions, decentralized identity, reputation systems, and AI-powered discovery to create a marketplace where trust is built into the infrastructure.

A developer can upload an AI model and license it.

A creator can publish a workflow and earn from it.

A researcher can share a dataset with clear usage rights.

A small business can buy an AI agent without building one from scratch.

A student can learn AI, create a useful tool, and publish it to the marketplace.

A community can validate, improve, and govern the intelligence it depends on.

That is the heart of JoyMarketplace: intelligence becomes opportunity.

Joy Marketplace is more than a place to buy and sell AI tools. It is an economic engine for the people. It is a learning system, a creator economy, a trust layer, a deployment hub, and a pathway into the future of work. Through Joy Academy, people can learn how to use AI. Through JoyMarketplace, they can publish what they build. Through Joy agents, they can automate and scale their work. Through decentralized ownership, they can keep control of the value they create.

This creates a new cycle:

People learn AI.

People build with AI.

People publish AI assets.

Businesses and communities use those assets.

Creators earn.

Revenue funds more education, better tools, more languages, more agents, and more access.

The ecosystem grows.

Joy Marketplace also solves one of the biggest problems in AI: trust. As AI assets multiply, people need to know what they are using, who created it, how it performs, what it is allowed to do, and whether it aligns with ethical and community standards. JoyMarketplace brings trust to AI through reputation, transparent licensing, smart contracts, provenance, community feedback, and ethical scoring. The goal is not just more AI. The goal is better AI, accountable AI, useful AI, and human-centered AI.

For creators, Joy Marketplace means ownership.

For businesses, it means access.

For students, it means opportunity.

For communities, it means participation.

For the world, it means AI does not have to belong only to the largest corporations.

At its core, Joy Marketplace is a movement toward a more open, fair, transparent, and joyful AI economy. It is built on the belief that intelligence should not be locked away, opportunity should not be centralized, and the people creating the future should have a real stake in it.

Joy Marketplace is where AI becomes accessible.

Where creators become owners.

Where businesses find trusted intelligence.

Where students become builders.

Where agents become workers.

Where communities shape technology.

Where intelligence becomes opportunity.

And where the next generation of AI is powered by the people.

Progress During Hackathon

During the buildathon, Joy Marketplace progressed from a concept into a working agentic commerce platform deployed on Arbitrum Sepolia. The system now includes deployed smart contracts, gasless USDC purchasing, ENS-named stores, ERC-8004 identity and reputation, NFT edition creation, revenue splitting, subgraph indexing, IPFS agent metadata, frontend integration, and MCP tools that allow AI agents to transact on-chain. All core contracts were deployed on Arbitrum Sepolia, chain ID 421614. This includes the IdentityRegistry, ReputationRegistry, ValidationRegistry, JoyStoreRegistrar, EditionController, JoyRegistrationSplitter, DropERC1155, ENSRegistry, BaseRegistrar, JoyResolver, and JoyRegistrarController. Together, these contracts create the foundation for identity, reputation, naming, payments, fee distribution, and NFT issuance directly on Arbitrum. A major milestone was building a gasless buyer experience using USDC. Buyers can purchase editions by signing an EIP-3009 transferWithAuthorization message. They only need USDC and do not need ETH for gas. The relayer pays the Arbitrum gas, settles the USDC payment, and claims the NFT to the buyer. This was proven with a fresh buyer wallet holding 0 ETH that successfully purchased an edition, paid USDC once, and received the NFT. Because the public x402 facilitator does not support Arbitrum Sepolia settlement, we built our own self-facilitating x402 v2 server. This server verifies EIP-3009 signatures, settles Circle’s official Arbitrum Sepolia USDC, and submits the transaction through the relayer. The payment network identifier used throughout the system is eip155:421614. Joy Marketplace also now supports ENS-named stores on Arbitrum. Stores can register a human-readable name such as label.joymarketplace.io through the JoyRegistrarController. The openStore flow links the ENS node to the ERC-8004 identity on-chain. This was proven through ENS registration, openStore execution, creation of storeId 1, and resolver text records written on-chain. The platform now uses ERC-8004 identity and reputation directly on Arbitrum. Each store and each edition receives its own ERC-8004 identity NFT. Reputation is also fully on-chain through feedback functions, with ownership-gated reputation submission. This was proven by submitting edition feedback and reading back both edition and store reputation from the chain. Revenue splitting was also implemented on Arbitrum. Registration fees are split 50 percent to the platform and 50 percent to the DAO through JoyRegistrationSplitter. Edition sales are distributed in Arbitrum USDC using an 80 percent seller, 10 percent compute, 5 percent platform, and 5 percent DAO split through relayer fan-out. Edition minting and claiming are live on Arbitrum. EditionController creates editions through the thirdweb DropERC1155 contract and assigns an ERC-8004 identity to each edition. Buyers receive ERC-1155 NFTs on Arbitrum through the relayer claim flow. This was proven through the full createEdition, claim, and buyer ownership lifecycle. AI agent functionality was added through an MCP server with seven Arbitrum-aware tools: store_register, edition_create, edition_buy, store_reputation, edition_reputation, store_discover, and agent_get. These tools allow AI agents to register stores, create editions, buy editions, and read reputation. All write tools are relayer-signed and execute on Arbitrum Sepolia. Custom discovery tools were built because the third-party 8004-MCP could not reach Arbitrum. Two Goldsky subgraphs were created to index Arbitrum Sepolia activity. The joy-stores-arbitrum-sepolia subgraph indexes agents, stores, feedback, validation, and ENS domains. The joy-drop-arbitrum-sepolia subgraph indexes editions, purchases, reputation scores, and reputation events. This makes the system queryable by both the frontend and AI agents. Each store and edition also receives a zod-validated AgentCard pinned to IPFS. The IPFS CID is written as the tokenURI on the Arbitrum IdentityRegistry. Verification scripts confirm that the on-chain tokenURI resolves to the IPFS gateway and matches the expected schema. This anchors off-chain metadata to on-chain Arbitrum identities. The frontend is now Arbitrum-aware end to end. The shared contract config includes the full Arbitrum Sepolia address book. Store discovery fans out across chains and merges results so Arbitrum stores appear in the gallery. The market drop detail modal detects Arbitrum Sepolia and routes buyers through the gasless x402 USDC flow with correct 6-decimal USDC formatting and Arbitrum explorer links. The open store, buy edition, and reputation hooks all switch the wallet to Arbitrum Sepolia before writing. Quality validation was completed across the stack. Slither reported zero medium-or-higher findings on the registrar contract. Contract and server tests passed across JoyStoreRegistrar, EditionController, JoyRegistrationSplitter, the x402 server, and MCP smoke tests. Live Arbitrum Sepolia transactions proved ENS registration, store opening, edition creation, NFT claiming, reputation submission, x402 USDC settlement, and gasless NFT claim. In summary, the buildathon produced a working, deployed, and tested Arbitrum-based agentic commerce stack. Joy Marketplace now has ENS-named stores, ERC-8004 identities, on-chain reputation, gasless USDC purchases through x402 and EIP-3009, multi-party revenue splits, NFT edition ownership, IPFS-anchored agent cards, real-time subgraph indexing, and MCP tools that allow AI agents to transact directly on Arbitrum. One-line judge summary: Joy Marketplace is a fully on-chain agentic commerce platform on Arbitrum Sepolia, combining ENS-named stores, ERC-8004 identity and reputation, gasless USDC purchases, x402 settlement, NFT editions, revenue splitting, subgraph indexing, IPFS agent metadata, and MCP tools that let AI agents register, sell, buy, and build reputation through real Arbitrum transactions.

Fundraising Status

Joy is currently in the **pre-seed stage**, which means we are entering at the ground floor of a major opportunity. We have completed the vision, market positioning, pitch narrative, and early product direction, and we are now raising our first focused round to move from prototype into phase one of the marketplace build. This is the stage where early supporters can have the greatest impact. The technology is timely, the market is forming quickly, and the need is clear: creators need ownership, businesses need trusted AI tools, and communities need a fair way to participate in the AI economy. Our current raise is designed to help us build the core foundation of JoyMarketplace — including the upload flow, ownership protection, marketplace listings, smart contract licensing, and early blockchain integration. Being pre-seed is not a limitation. It is the opportunity. It means we are early, focused, lean, and positioned to build before the market becomes crowded. Early contributors, partners, and investors have the chance to help shape Joy from the foundation up.
