🧐 What Is ERC-8004?

ERC-8004 gives AI agents a portable, on-chain identity — like a passport for the agent economy.

It's a standard for discovering, choosing, and interacting with agents across organizational boundaries without pre-existing trust. No API keys. No vendor lock-in. Just smart contracts.

In plain English: Your AI agent gets an NFT (ERC-721) that says who it is, what it can do, and where to reach it. Anyone can verify it on-chain. Forever.

Option 2: Run locally

git clone https://github.com/sperax/erc8004-agent-creator.git
cd erc8004-agent-creator
open index.html
# That's literally it. No npm. No build. No config.

Option 3: Self-host

Drop index.html on Vercel, Netlify, GitHub Pages, IPFS, or any static host. One file.

✨ Features

🌐 Supported Chains

Testnets

Mainnets

📜 Contract Addresses

Testnet Contracts (Shared across all testnets)

Mainnet Contracts (Shared across all mainnets)

All contracts use CREATE2 vanity deployment with 0x8004 prefix via the SAFE Singleton Factory, ensuring identical addresses across all chains.
