Description
SmartChain Hub is a decentralized AI commerce platform where every user owns a sovereign AI agent with verifiable on-chain identity, persistent cross-session memory, and cryptographically proven intelligence powered entirely by the 0G modular stack.
Unlike projects that bolt AI onto a wallet, SmartChain Hub implements the full agentic loop:
1. IDENTITY
SmartChainAgentID.sol mints a soulbound NFT (one per wallet, non-transferable) storing the agent's TensorFlow model hash, 0G Storage KV memory root, and reputation score. Reputation increments on every confirmed optimization.
2. INTELLIGENCE
The AI agent runs LLaMA 3.1 8B inside a Trusted Execution Environment via 0G Compute TeeML mode. Every inference returns a cryptographic TEE proof displayed in the UI users can verify the AI ran correctly.
3. MEMORY
Agent memory (preferred routes, past savings, user behavior) is persisted to 0G Storage KV layer across browser resets and devices. The memory Merkle root is committed on-chain after every session.
4. RECEIPTS
Every transaction optimization uploads an immutable receipt to 0G Storage Log layer via @0glabs/0g-ts-sdk. The Merkle root is stored in Supabase and on-chain simultaneously.
5. ECONOMICS
SmartChainPayments.sol collects a 0.5% fee on every transaction. SmartChainRevenue.sol distributes 10% proportionally to registered stakers. Users earn 5% APY on staked A0GI.
Every single user action generates exactly 3 on-chain interactions: 1 Storage upload + 1 Agent ID memory update + 1 revenue event. This is the economic flywheel.
The platform also integrates M-Pesa (via Flutterwave) and Stripe onramps, targeting emerging markets where fee optimization has the highest real-world impact Sub-Saharan Africa and Southeast Asia.

Tech Stack
Fundraising Status
<p>Pre-seed stage. We have a fully functional MVP deployed on 0G Galileo Testnet with live contracts, a working AI agent, and a production frontend. We are actively seeking $150K–$300K seed funding to deploy on 0G Mainnet, onboard the first 1,000 Agent IDs, and launch the M-Pesa integration for East African markets. The economic flywheel is live every optimization generates staking rewards, creating organic user retention without paid acquisition.</p><p></p>
