Cross-Chain

Register your coin's ticker (its short name, like $PEPE) from the same wallet on each chain, and they all show up on one coin page, with a switcher to move between chains. There's no linking step and no linking fee.

You get:

• One name across all your chains
• One public coin page listing every chain, with a chain switcher
• Your coin in a Token List, the standard file wallets and exchanges read
• Per-chain details, so each chain's page can say what fits that chain

Adding a Chain

1. Open Select Chain. In your coin manager, click your coin's logo and ticker at the top, and press Add Chain.

2. Pick the chain. Chains you already have are marked "Already peered". Two or more chains in one order get 10% off.

3. Register or create on that chain, priced as a normal registration (or creation and registration). Pricing
4. Done. Once the new registration confirms, it links to your existing ones and appears on the same coin page.

Same wallet, not same creator

Linking follows the wallet that owns the registrations, not the wallet that created each coin:

• Register from the same wallet. Registrations share one coin page only when the same wallet owns them on every chain. Different wallets stay separate.
• The coin itself can come from anywhere. Each chain's coin may have a different deployer, as long as the wallet you register with passes that chain's ownership verification.

Linking Is Automatic

When the same wallet registers the same ticker on another chain, the registrations link as equal peers: one name, one coin page with a chain switcher, and inclusion in the Token List. There's no primary chain.

Each chain's registration is its own on-chain action, so you sign once per chain: three chains, three signatures. Bundled or not, every multi-chain registration links the same way.

Your dashboard shows the same group: one ticker on three chains, one coin.

Each chain's page is edited separately

One page and one chain switcher, but name, description, logo, social links and contract details are set per chain. Editing one chain's page changes that chain only; to update every chain, switch to each one and save.

One registration per chain per wallet

A wallet can link one registration per chain for a ticker. DOGE on Arbitrum, DOGE on Base and DOGE on Solana make one group; a second Solana DOGE from the same wallet is refused.

To point a chain at a different coin (say, moving DOGE on Solana to a new mint), remove the existing one first, then add the new one. A second registration of the same ticker on the same chain needs a different wallet, and stays on its own page.

Token List

Linked registrations are published in a Token List (in crypto terms, a coin is a token), the standard file wallets and exchange aggregators read. They pick up your updates without a listing application.

It includes your coin's name, symbol, decimals, logo, and the contract address and chain ID on each chain. It's served at GET /api/v2/tokenlist, or GET /api/v2/tokenlist?chainId=42161 for one chain.

To send your coin's details to exchanges and aggregators yourself, use Listing Export.
