First Gasless Registration

The first-ever gasless agent registration on the Agent Registry -- proof that the ERC-2771 meta-transaction flow works end-to-end on a live blockchain.

Gas Cost 0.00000194274 ETH (~$0.005)
Cost to Agent $0.00

What This Proves

Three key proofs

  1. Gasless registration works on a live blockchain. The agent wallet had zero ETH. It signed an EIP-712 message locally (free). The relayer submitted the transaction and paid 0.000002 ETH in gas.

  2. The agent is publicly verifiable. Anyone can call isRegisteredAndCompliant(0x4b19...) on Base Sepolia and confirm the registration -- no API, no trust required.

  3. The cost is negligible. At $0.005 per registration, the relayer can register approximately 8,000 agents per dollar on Base L2.

Verification Commands

Check the contract state from the command line:

# Check total agents registered
node -e "
const { ethers } = require('ethers');
require('dotenv').config();
const p = new ethers.JsonRpcProvider('https://sepolia.base.org');
const r = new ethers.Contract(
  '0x2EFaB5B3BEf49E56a6Ce1dcB1A39EF63C312EA23',
  ['function nextAgentId() view returns (uint256)',
   'function isRegistered(address) view returns (bool)'], p);
(async () => {
  console.log('Total agents:', Number(await r.nextAgentId()) - 1);
  console.log('Agent #1 registered:',
    await r.isRegistered('0x4b192fD5c4f24cE23000B49f31CF3d7484Ccf252'));
})();

# Check wallet balances
npm run addresses

Next Steps

  • Run scientific experiment scenarios
  • Security audit
  • Governance transition (owner -> multi-sig -> DAO)
  • Mainnet deployment (Base L2)
