Activate an ENS Name

Open the Onchain section

1. Visit app.namespace.ninja/onchain.
2. Connect the wallet that owns the ENS name you want to activate.
3. Select your ENS name from the dropdown at the top, then click Activate Name.

Choose the listing type

Pick where subnames will be issued:

• L1 ENS Subnames — issue original ENS subnames on Ethereum mainnet.
• L2 ENS Subnames — issue subnames on a supported L2 chain (Base or Optimism). Pick the network from the “Select Subname Network” dropdown.

Click Next.

Setup — base activation properties

Configure the collection:

• Currency — the token mint fees are collected in (e.g. ETH or USD).
• Treasury Address — wallet that receives mint revenue.
• Name and Symbol — collection metadata.
• Burnable — allow subname holders to burn their subname.
• Renting — allow time-bound subname rentals.

Prices — mint pricing rules

Set how subnames are priced:

• Base Price — default price for every subname. Set to 0 to make subnames free.
• Prices by length — override price for specific subname lengths (e.g. 3-char names cost more).
• Special Name Pricing — custom rules for emoji-only, numbers-only, or other patterns.

Reservations — block or specially price specific subnames (optional)

Reserve subnames so they either cannot be minted at all (set Mintable off → “No Mint”) or are minted at a specific price different from your base rules.Add reservations one-by-one or bulk-import via CSV.

Deadline — set a minting cutoff (optional)

Toggle Use Deadline to make the collection time-bound. After the chosen date, no new subnames can be minted.

Whitelist — restrict who can mint (optional)

Toggle Use Whitelisting to gate minting by wallet address. Two modes:

• Can mint only if whitelisted — restrict minting to listed wallets.
• If whitelisted, can mint for free — allowlisted wallets bypass the mint fee.

Add addresses or ENS names one-by-one.

Token Gated — require token holdings (optional)

Toggle Use Token Gated Listing to require that minters hold a specific token:

• Standard — ERC-20 or ERC-721.
• Token Address — contract address of the gating token.
• Subname Network — the chain the token lives on.
• Minimum Amount Required — minimum balance the wallet must hold to be eligible.
