    message,
    recipientKey
  });
  return result.encryptedMessage;
}

3. Integrate with Solana

// Example of verifying TEE attestation on Solana
import { Connection, Transaction, PublicKey } from '@solana/web3.js';

async function verifyAttestation(connection, attestation, teePublicKey) {
  const transaction = new Transaction().add(
    attestationProgram.instruction.verify({
      teePublicKey: new PublicKey(teePublicKey),
      attestation: attestation,
    })
  );
  return connection.sendTransaction(transaction, [payer]);
}

4. Add AI Capabilities

// Example of running AI in TEE
async function processMessageWithAI(enclave, encryptedMessage, userKey) {
  // AI runs inside the enclave
  return await enclave.invokeSecure('analyzeMessage', {
    encryptedMessage,
    userKey
  });
}

TEE in Web 3

Welcome to the TEE in Web 3 Guide powered by TEEChat and TEEGPT. These platforms offer fully decentralized private AI messaging using TEEs on the Solana blockchain.

What is Decentralized Private AI Messaging?

At its core, decentralized private AI messaging combines several cutting-edge technologies to create secure, private communication systems powered by artificial intelligence:

• Trusted Execution Environments (TEEs): Think of these as ultra-secure digital vaults inside computer processors where data can be processed without anyone - not even the system administrators - being able to see what's happening inside.

• Blockchain (like Solana): A distributed ledger technology that records transactions across many computers, making the system transparent, verifiable, and resistant to tampering.

• Privacy technology: Tools that help manage digital identities and sensitive information while maintaining user control and confidentiality.

• AI Agents: Intelligent software that can perform tasks, make decisions, and interact with users on their behalf.

Why This Technology is Revolutionary

Imagine having AI assistants that can handle your most sensitive information while guaranteeing that:

• Your data remains encrypted and private

• No central company or government can access your communications

• The system is resistant to censorship

• You maintain ownership and control of your digital identity

Use Cases For TEE in Web 3

How do we use TEE, and what use cases can we implement right now on Solana using TEE and AI Agents:

1. Private DeFi Assistants

AI agents operating in TEEs could manage your DeFi portfolio, executing trades and yield farming strategies without exposing your wallet contents or trading strategies to anyone. The blockchain verifies transactions while the TEE ensures privacy.

2. Secure Crypto Trading Signals

Trading signals and analysis could be generated by AI within TEEs using proprietary algorithms that remain secure, while still providing verifiable results on the blockchain.

3. Cross-Chain Privacy

TEEs could facilitate private cross-chain transactions where AI agents coordinate asset transfers between different blockchains without exposing transaction details.

4. On-Chain AI Governance

DAOs (Decentralized Autonomous Organizations) could employ AI agents in TEEs to help analyze proposals and execute governance decisions with guaranteed integrity.

5. Private NFT Creation and Trading

Artists could use AI assistants to create and trade NFTs while keeping their creative process and identity private if desired, with the blockchain only recording the final transaction.

6. Front-Running Protection

TEEs can prevent malicious actors from seeing pending transactions before they're confirmed, protecting users from front-running attacks that plague many DeFi protocols.

How People Can Make Money With It

There are several ways to monetize this technology:

• Building and Selling TEE-Secured AI Applications: Developers can create specialized AI agents that operate within TEEs for specific industries like healthcare, finance, or legal.
