⚔️ ChainYodha.AI

ChainYodha.AI is an AI-powered onchain risk and trust intelligence layer — built on Arbitrum — that assigns real-time TrustScores to wallets, smart contracts, and DeFi protocols. It protects users from scams, fraud, and rug-pulls by giving them transparent, AI-evaluated risk data — directly in the wallet, dApp, or payment flow.

By combining onchain activity, AI analytics, and social graph signals, ChainYodha.AI becomes your “digital warrior” — defending Web3 users and builders from hidden threats.

🧠 Why ChainYodha.AI?

India is rapidly adopting Web3 — but users face:

• Fake UPI-to-token swap scams

• Rug-pull NFT collections

• Fraudulent Arbitrum stablecoin wallets

• No public “reputation score” for wallets or smart contracts

ChainYodha.AI solves this with a decentralized, composable TrustScore system that evaluates:

✅ Wallet behavior (risk flags, tx patterns, scam tokens)
✅ Onchain identity + social links (Farcaster, GitHub, ENS, Lens)
✅ Smart contract audit data, developer credibility
✅ AI-generated flags from LLMs trained on fraud patterns
✅ Community reporting + reputation consensus

🛡️ Use Cases

• 🪙 DeFi: Score-based lending, trust-verified liquidity providers

• 📦 P2P & Stablecoins (arbINR, USDC): Know before you send

• 🛍️ Merchants: Embed ChainYodha badge to prove payment wallet trust

• 🔐 Wallets & DApps: Show risk levels at connect time

• 📲 Discord/Telegram Bots: Community wallet vetting

⚙️ Architecture

• Network: Arbitrum One (main deployment)

• Smart Contracts: Solidity + Stylus (Arbitrum Nitro compatible)

• AI Engine: Open-source LLM risk analyzers + onchain behavior scoring

• Frontend: Next.js (React + Wagmi)

• Wallets: MetaMask, MathWallet, TrustWallet

• Multi-chain Support: Ethereum, Solana, Arbitrum, Polygon

🧩 Modules

• TrustScoreOracle.sol – Main scoring contract

• IdentityLinker.sol – Social + DAO linkage to wallet

• ChainYodhaBadge.sol – ERC-721 trust badge

• ScoringValidator.sol – Verifies offchain AI score hash onchain

• ProofStore.sol – Stores IPFS hashes of audit data, social proofs

🧰 Tech Stack

• Blockchain: Arbitrum One, Arbitrum Orbit (future-ready)

• Smart Contracts: Solidity, Stylus (for advanced L2 logic)

• Frontend: Next.js, TypeScript, TailwindCSS

• AI Stack: VectorDB (Weaviate), LLM-based classification

• API Layer: Node.js + REST endpoints

• SDK: ChainYodha TypeScript SDK

🔁 Example Workflow

1. User connects wallet in dApp

2. ChainYodha API/contract fetches TrustScore

3. Frontend shows visual badge (🟢 Trusted, 🟡 Risky, 🔴 Dangerous)

4. dApp adjusts behavior (e.g., disallow transfer, flag user)

🇮🇳 India-Relevant Impact

• Stops fake payment links with arbINR or stablecoin integrations

• Enables safe tokenized land ownership & gold-backed RWA usage

• Lets freelancers verify clients before accepting payment

• Prevents UPI-to-wallet scams using social trust overlay

• Builds confidence for Bharat users in Web3

🧪 Sample Commands & Queries

• /score 0xABCD... → 🟢 Trusted | Score: 91

• /verify raj.eth → Linked to GitHub + ENS + Lens ✅

• /scan smart contract → Suspicious: Reentrancy loop
