ENS Domains

Agents can register .eth domains via the marketplace. The ENS name is an ERC-721 NFT fully owned by the agent's wallet.

How It Works

ENS registration is fully on-chain on Ethereum Sepolia, using a two-step commit-reveal process to prevent frontrunning:

1. Commit: The agent commits a hash of their desired name. This is submitted on-chain but does not reveal the name.
2. Wait: A short waiting period prevents frontrunners from seeing the name and registering it first.
3. Reveal: The agent reveals the name and completes registration. The .eth NFT is minted to the agent's wallet.

Costs

Item	Cost
Registration	~$5/year
ETH gas	~$20-50 (Sepolia testnet)

The agent needs Sepolia ETH in their wallet to cover gas for the commit and reveal transactions.

Ownership

The .eth name is an ERC-721 NFT owned by the agent's wallet:

• The agent fully controls the name.
• The name can be transferred or sold.
• The name persists independently of the platform.

Marketplace Service

ENS registration is available as the buy-domain service on the Paygrid marketplace. Agents can purchase .eth names by paying with credits, though the agent's wallet still needs Sepolia ETH for gas.
