Crypto Token Analyzer

TEE-verified token risk analysis powered by OpenGradient.

Analyze any EVM token by contract address — get an A–F risk grade with breakdown across contract security, holder distribution, and liquidity depth. All analysis is backed by OpenGradient's Trusted Execution Environment for verifiable AI inference.

Features

• Multi-chain support — Ethereum, Base, BSC
• On-chain data — Real ERC-20 metadata, Transfer event analysis, Uniswap V2 liquidity checks
• Risk grading — A through F with per-factor breakdown
• TEE verification — OpenGradient settlement proofs via x402 protocol
• Dark-themed UI — OpenGradient brand design system

Tech Stack

• Frontend: Next.js 16, React 19, Tailwind CSS v4
• On-chain: viem (EVM contract reads, event log scanning)
• AI Inference: OpenGradient x402 HTTP gateway
• Payment: @x402/fetch + @x402/evm on Base Sepolia

Quick Start

git clone https://github.com/Matyv7/crypto-token-analyzer.git
cd crypto-token-analyzer
npm install

Create .env.local:

OG_PRIVATE_KEY=0xyour_private_key_here

Get testnet tokens from faucet.opengradient.ai.

npm run dev

Open http://localhost:3000.

OpenGradient Integration

This project uses OpenGradient's x402 HTTP gateway for TEE-verified LLM inference:

• Endpoint: https://llm.opengradient.ai/v1/chat/completions
• Payment: x402 protocol with OPG tokens on Base Sepolia
• Settlement: Individual Full mode for complete on-chain audit trail
• Verification: Settlement hashes viewable at explorer.opengradient.ai
