A marketplace where experts upload SKILL.md files, buyers chat with AI agents powered by those skills, and creators earn on-chain royalties via 0G every time their skill runs.
AI agents are only as good as the knowledge behind them. Today, that knowledge lives in the heads of domain experts — lawyers, financial analysts, senior engineers, seasoned traders — who have no way to monetize it in the age of AI. Meanwhile, buyers pay for generic AI that doesn't know their industry, their edge cases, or their standards.
There's no marketplace for AI expertise. Until now.
SkillMarket is an on-chain AI skill marketplace built on 0G Chain. Experts publish SKILL.md files — concise, structured system prompts that encode deep domain knowledge and teach Claude a specialized skill. Buyers browse the marketplace, select the skill they need, and chat with a Claude agent powered by that expert's knowledge. Every time a skill runs, the creator earns an on-chain royalty — automatically, instantly, without intermediaries.
Think of it as the App Store for AI expertise, where the apps are skills, the developers are domain experts, and every install pays a royalty in real time.
Experts publish — An expert writes a SKILL.md file encoding their methodology, frameworks, and domain knowledge. They register it on-chain and upload it to 0G's decentralized storage network.
Buyers chat — A buyer selects a skill and starts a conversation. The backend injects the expert's SKILL.md as a system prompt with prompt caching for low-latency, cost-efficient responses powered by Claude.
Royalties fire on-chain — After each message, the platform calls executeSkill() on the SkillRegistry smart contract on 0G Chain, splitting the payment between the creator and the platform with zero manual steps — no wallet popups, no friction.
Storage on 0G — All skill metadata and content is stored on 0G's decentralized storage network, keeping it verifiable, permanent, and censorship-resistant.
0G Chain is purpose-built for AI-native applications — high throughput, low fees, and a decentralized storage layer that makes on-chain AI content practical at scale. SkillMarket uses 0G for both the royalty settlement layer and as the content backbone for skill storage, making every skill traceable, ownable, and monetizable on-chain.

Every expert in the world has knowledge worth paying for. SkillMarket gives them a one-file publishing tool to turn that knowledge into a recurring, passive income stream — powered by AI, settled on-chain, and available to any buyer anywhere in the world.
