AI Model Marketplace

Discover how developers and smart contracts interact with on-chain AI models through the world’s first decentralized model marketplace.

GrantChain introduces the first fully on-chain AI model marketplace — a decentralized registry where AI becomes a programmable, composable primitive for smart contracts, agents, and dApps.

🔍 What It Does

The marketplace allows:

• 🧑‍💻 Developers to upload and monetize models

• 📦 Smart contracts to consume models via API-like calls

• 📈 Token holders to fund or vote on new model integrations

• ✅ Users to verify model execution via zkML

---

🧰 Key Features

1. Model Uploads

AI researchers and builders can:

• Upload trained models (e.g., LLMs, classifiers, predictors)

• Version them (v1.0, v2.1...)

• Add metadata like pricing, description, licensing

• Link to IPFS or Arweave model files

2. On-Chain API Access

Every model receives a unique callable interface:

jsCopyEditcontract.callModel("model_id", { input: "user query" });

No off-chain bridges. No third-party oracles. Just native AI interaction on-chain.

3. Pay-per-Execution

Each call to a model deducts $GRANT from the caller and rewards the model owner.

• Execution revenue = usage × fee

• Model devs earn income for providing inference

4. zkML Proofs

Every execution can optionally emit a zero-knowledge proof of correctness, ensuring that:

• The right model ran

• The output is valid

• The computation was not tampered with

💡 Why It Matters

• Smart contracts can now “think” — not just execute logic

• Models become public infrastructure, like liquidity pools

• Developers finally have a native monetization path for AI work

Think of it as the Uniswap for intelligence — programmable, open, and verifiable.
