MetaCoreX

Web3 / Web4 Infrastructure for the ARZY-G AI Token Ecosystem

MetaCoreX is a full-stack Web3/Web4 infrastructure project built around the ARZY-G ERC-20 AI token — an on-chain token with an embedded AI integration layer, Chainlink Functions oracle support, and a real-time Operator Console dashboard (in the metacorex-site frontend).

Overview

ARZY-G is an ERC-20 AI token with an on-chain intelligence layer. Unlike standard ERC-20 tokens, ARZY-G enforces that new tokens are minted only after an AI agent submits a verifiable proof of useful computation — evaluated and settled on-chain via Chainlink Functions.

Core capabilities:

Feature	Description
`registerAgent` / `submitProof`	Permissionless — any wallet registers itself and mints `amount * score / 10` by self-reporting a proof + score (0–10), no oracle round trip required
`requestUsefulness` → `birthToken`	Oracle-verified path: a Chainlink Functions callback approves a proof (score ≥ 1) and mints, split 99% agent / 1% protocol reserve
`Daily Quota`	Both mint paths share a global `dailyMintLimit` and a per-agent `agentDailyCap`, enforced on-chain via a UTC day epoch
`Supply Cap`	Hard `MAX_SUPPLY` ceiling (1,000,000,000 ARZY-G) enforced in every mint path via `_update`

Proof of Usefulness (PoU) Protocol

The Proof of Usefulness protocol is MetaCoreX's core economic and consensus mechanism. It replaces arbitrary inflationary minting with a verifiable, AI-evaluated work gate.

   │◀── ProofRejected event ────│    emit ProofRejected()  │

PoU Score

Every submitted proof carries a PoU Score — an integer from 0 to 10 — but it means slightly different things on the two mint paths:

Path	Score	Result
`submitProof` (direct, self-reported)	`0`	`ProofRejected` — no mint
`submitProof` (direct, self-reported)	`1–10`	`ProofAccepted` — mints `amount * score / 10`
`requestUsefulness` → oracle callback	`0`	`OracleProofRejected` — no mint
`requestUsefulness` → oracle callback	`≥ 1`	`TokenBirthed` — mints the full pre-agreed amount (99% agent / 1% reserve)

The PoU Score is displayed in real time on the Operator Console dashboard.

Roles

Role	Capability
`DEFAULT_ADMIN_ROLE`	Full contract governance, can reassign `RESERVE_ROLE`
`DEV_ADMIN_ROLE`	Trigger `requestUsefulness`, update `dailyMintLimit` / `agentDailyCap`
`RESERVE_ROLE`	Held by the protocol fee reserve address

registerAgent and submitProof are intentionally permissionless — no role is required, so any wallet (including third-party agents) can call them directly. See Connect Your Own Agent.

Daily Quota

Every AI-driven mint (submitProof and birthToken) shares a global daily limit and a per-agent cap, enforced on-chain using the UTC day epoch:

uint256 day = block.timestamp / 1 days;
require(mintedInDay[day] + amount <= dailyMintLimit, "Daily mint limit exceeded");
require(agentMintedInDay[agent][day] + amount <= agentDailyCap, "Agent daily cap exceeded");

This prevents runaway minting while still allowing high-throughput AI pipelines across many independent agents. Both limits are admin-adjustable (setDailyMintLimit, setAgentDailyCap) and a hard MAX_SUPPLY ceiling backstops every path regardless of quota.

Event Flow

The MetaCoreX EventBus (src/ws/eventBus.ts) is the central nervous system of the OS. All on-chain events are captured by ContractService via ethers.js listeners and republished to all connected metacorex-site dashboard clients over WebSocket in real time.

Blockchain Event  ──▶  ContractService  ──▶  McxEventBus  ──▶  WebSocket  ──▶  Dashboard
(MintRequested)         (ethers.js)          (EventEmitter)      (/api/ws)      (Terminal)

System Metrics

These are the live on-chain system metrics exposed by the dashboard and API:

Metric	Source	Update Frequency
Token Balance	`ARZYG.balanceOf(deployer)`	Every 5 seconds
Total Supply	`ARZYG.totalSupply()`	Every 5 seconds
Block Number	`provider.getBlockNumber()`	Every 5 seconds
Chain ID	`provider.getNetwork()`	On connect
PoU Score	WebSocket event stream	Real-time
Pending Requests	`MintRequested` event counter	Real-time
Minted / Birthed / Rejected	On-chain event counters	Real-time

Quick Start

Prerequisites

Node.js 24+
pnpm 10+

1. Install dependencies

pnpm install

2. Start the Hardhat local node

HARDHAT_DISABLE_TELEMETRY_PROMPT=true pnpm --filter @workspace/contracts run node

3. Compile and deploy contracts

# Compile
pnpm --filter @workspace/contracts run compile

# Deploy to local node (writes contracts/deployed.json)
pnpm --filter @workspace/contracts run deploy:local

4. Run the API server

pnpm --filter @workspace/api-server run dev

This serves only the JSON API at /api/* (health check: http://localhost:8080/api/healthz).

5. Run the frontend

pnpm --filter @workspace/metacorex-site run dev

The Operator Console dashboard and marketing site are now live wherever that dev server prints its local URL.

6. Run contract tests

pnpm --filter @workspace/contracts run test

Environment Variables

Variable	Required	Description
`PORT`	Yes	API server port (default: 8080 via workflow)
`DATABASE_URL`	Yes	PostgreSQL connection string — the server throws at startup without it
`SEPOLIA_RPC_URL` / `ETH_RPC_URL`	Recommended	Overrides the RPC URL in `contracts/deployed.json` at runtime
`DEPLOYER_PRIVATE_KEY`	Optional	Needed only for server-signed admin transactions (e.g. `/api/contract/mint-demo`)
`GITHUB_TOKEN`	Deploy only	GitHub PAT for pushing to the repository

Operator Console Dashboard

The Operator Console (artifacts/metacorex-site, the /dashboard route) is the real-time interface that bridges the blockchain and the operator — token balance/supply, agent status and PoU score, the live on-chain event feed, and PoU/verification submission tabs. It talks to the API server's JSON routes and subscribes to the McxEventBus over /api/ws for live updates (MintRequested, TokenBirthed, AgentStatusChanged, etc.) — see Event Flow above.

It is a separate deployable artifact from the API server; run it locally with pnpm --filter @workspace/metacorex-site run dev, or deploy it independently per docs/deploy-render.md.

Connect Your Own Agent

You can point your own AI agent at MetaCoreX without ever sharing a private key with us. registerAgent and submitProof on ARZYG_ERC20_AI.sol are permissionless — any wallet can call them directly on-chain.

Fork this repository. (The GitHub Actions template runs scripts/src/github-agent.ts inside the full pnpm workspace — copying just that file into an unrelated repo won't work standalone.)
Add two GitHub Actions secrets in your fork — AGENT_PRIVATE_KEY (your agent wallet) and SEPOLIA_RPC_URL (any Sepolia RPC endpoint) — plus an API_BASE_URL repo variable pointing at the published MetaCoreX API.
Fund that wallet with a little Sepolia ETH for gas from a public faucet.
Enable Actions — .github/workflows/agent.yml registers your agent and submits proof-of-work on a schedule, signing directly with your own key.

Prefer to run it yourself, in Node or Python, outside GitHub Actions? Copy-pasteable standalone scripts are in examples/: agent-example.js (ethers.js) and agent_example.py (web3.py).

Full details, including the on-chain safety caps your agent needs to know about, are in docs/agent.md. The two API routes that accept a raw private key (/api/agents/register, /api/agents/submit-proof) are internal-only, gated by a token in a gitignored local file (never an env var, so forks never inherit it), and reserved for this project's own automation — third-party agents should not use them.

Airdrop Points (Testnet)

A Sepolia-testnet-only points program — a preview of a future distribution, not a live token payout. Points are never stored as a mutable counter; they're derived at query time from what's already on-chain/in the database, so early participants are automatically credited retroactively with no backfill step needed:

Activity	Points
Register your agent (`registerAgent`)	+100
Each accepted proof (`submitProof`)	+50
Each wallet you refer that goes on to register	+200

View your points, referral link, and the leaderboard at /airdrop on the Operator Console, or hit the API directly — see Airdrop / points in docs/api.md. The /api/airdrop/claim route is currently a stub ({ claimed: false }); real ARZY-G distribution is a post-mainnet feature.

Deployment

The API server (which also serves this dashboard) ships as a self-contained Docker image and deploys to Fly.io with the committed Dockerfile + fly.toml:

fly launch --no-deploy   # first time only, keeps the committed fly.toml
fly secrets set DATABASE_URL="postgres://..." SEPOLIA_RPC_URL="https://..."
fly deploy

Full step-by-step instructions, required secrets, and how to verify a deploy are in docs/deploy.md.
