Deploy On-Chain AI Agent

Deploy and register autonomous AI agents on Nexis Appchain with proof-of-inference and task execution

Deploy On-Chain AI Agent

Create autonomous AI agents that execute tasks on-chain with verifiable proof-of-inference.

Agent Registration

import { NexisAgents } from "@nexis-network/sdk";
import { ethers } from "ethers";

const provider = new ethers.JsonRpcProvider("https://testnet-rpc.nex-t1.ai");
const wallet = new ethers.Wallet(process.env.PRIVATE_KEY, provider);

const agents = new NexisAgents(wallet);

// Register agent
const agentId = "my-ai-agent";
const metadata = {
  name: "GPT-4 Assistant",
  description: "AI agent powered by GPT-4",
  capabilities: ["text-generation", "analysis"],
  endpoint: "https://api.myagent.com"
};

const tx = await agents.register(agentId, JSON.stringify(metadata), "https://api.myagent.com");
await tx.wait();
console.log("Agent registered:", agentId);

// Stake tokens
const stakeTx = await agents.stakeETH(agentId, { value: ethers.parseEther("1") });
await stakeTx.wait();

Agent Server

server.js

const express = require('express');
const { OpenAI } = require('openai');
const crypto = require('crypto');

const app = express();
const openai = new OpenAI({ apiKey: process.env.OPENAI_API_KEY });

app.use(express.json());

app.post('/execute', async (req, res) => {
  const { input, taskId } = req.body;
  
  // Hash input for proof
  const inputHash = crypto.createHash('sha256').update(input).digest('hex');
  
  // Execute AI task
  const completion = await openai.chat.completions.create({
    model: "gpt-4",
    messages: [{ role: "user", content: input }]
  });
  
  const output = completion.choices[0].message.content;
  const outputHash = crypto.createHash('sha256').update(output).digest('hex');
  
  // Record on-chain
  await recordInference(inputHash, outputHash, taskId);
  
  res.json({ output, inputHash, outputHash });
});

app.listen(3000, () => console.log('Agent server running on port 3000'));
