🌐 NEAR.AI — Cross Chain Tokenization Powered by AI Agents

Break asset barriers. Simplify cross-chain access. Let AI handle Web3.

---

🧩 The Problem

Web3 promises decentralization, but today's experience is fragmented and difficult:

• 🌍 Border Barriers of Assets
  Global users face restrictions in accessing real-world assets due to geographical and regulatory boundaries.

• 🔐 Fragmented Key Management
  Managing private keys across multiple chains is confusing, insecure, and a major hurdle for onboarding Web2 users.

• 🧠 Complex UX of Web3 dApps
  Users are forced to juggle between wallets, chains, and keys. What if they could simply “ask” in natural language?

---

✅ Our Solution

NEAR.AI brings together AI Agents, Tokenization, and Cross-Chain Signatures into a seamless Web3 interface:

💰 Tokenization of Assets

Real-world assets like stocks are digitized into tokens (e.g., tokenized Apple stock).

🔗 NEAR Cross-Chain Signatures

Use your NEAR wallet to interact with Ethereum, Solana, and beyond. One key, many chains — no need to manage multiple wallets.

🤖 AI Agents for Web3

Powered by ElizaOS, users describe actions in natural language (e.g., “Mint 1 Apple stock token on Ethereum”), and the AI agent executes it behind the scenes.

🚀 Example Flow

🟢 Mint Flow

1. User chats with the ElizaOS agent on NEAR

   "Buy 3 shares of AAPL using 10 ETH"

2. Agent sends the mint transaction using NEAR private key to the MPC contract to sign.

3. **MPC contract responds with the signature.

4. Signed transaction is broadcasted to the dNEAR smart contract on Ethereum

5. Oracle:

   • Fetches real-time AAPL stock price (USD)
   • Places an off-chain order to buy stock via custom JS

6. Chainlink Price Feed:

   • Fetches ETH/USD price

7. Smart Contract Logic:

   if (ETH_in_usd >= stock_price_usd * quantity) {
       mint DNEAR token(s);
       update totalHoldings[requester][stock];
       refund excess ETH;
   }
   
   

🚀 Redeem Flow

1. User chats with the ElizaOS agent on NEAR

   "Sell 3 shares of AAPL"

2. Agent sends the redeem transaction using NEAR private key to the MPC contract to sign.

3. **MPC contract responds with the signature.

4. Signed transaction is broadcasted to the dNEAR smart contract on Ethereum.

5. Oracle:

   • Fetches real-time AAPL stock price (USD)
   • Places an off-chain order to buy stock via custom JS

6. Chainlink Price Feed:

   • Fetches ETH/USD price

7. Smart Contract Logic:

   if (totalHoldings[requester][stock] >= quantity) {
   burn DNEAR token(s)
   update totalHoldings
   send back  ETH equivalent to stock_price_usd * quantity   }
