Lemo

Lemo is an agentic AI browser extension that automates online shopping by finding the best deals across marketplaces like Flipkart, Amazon, and others, while enabling crypto-based checkout and data monetization.

When a user searches for a product, the Lemo Agent scrapes product details, compares specs, and summarizes results with reasoning. Users can directly complete the purchase using stablecoins or 1MB DataTokens (reward-based claiming), making checkout fast and decentralized.

Each transaction is securely stored on Lighthouse decentralized storage, giving the user a verifiable spending ledger. Lemo also integrates EIP-8004 (Proof of Honor) — a feedback protocol where users rate the agent’s performance, generating a verifiable trust score for the AI. Every feedback submission rewards the user with 1MB DataTokens, creating an incentive loop around trust and data quality.

The collected transaction + feedback data (encrypted) forms a data coin on 1MB.io , enabling future ML training and monetization of aggregated insights while preserving privacy.

We had integrated the paypal's PYUSD in our project for the transaction with secure environment.

Lemo’s architecture combines AI, blockchain, and decentralized storage: Frontend: Built as a browser extension using React + TypeScript. It integrates the Gemini SDK for agentic reasoning, product summarization, and decision assistance. The UI allows wallet connection, browsing history, and feedback submission. 1mb tokens for reward giving. Backend: Built with Node.js (Express + TypeScript) as a separate service (/filecoin-example/backend). It handles: User session + wallet linking , Transaction logging ,Lighthouse SDK integration (uploads encrypted JSON logs + feedback data) ,Feedback API (EIP-8004 formatted proofs),Token reward flow using 1MB DataTokens and FVM smart contracts Smart Contracts (FVM): LemoHonor.sol implements EIP-8004 logic to maintain honor scores per wallet. RewardDistributor.sol automates 1MB token payouts based on verified feedback.
