What your coin can be priced in. A short list for discovery, anything else by account id, and a registry on chain that has the final word.

The three tabs

Any pair. NEAR, USDC, USDT, wBTC, ETH, ZEC, RHEA, stNEAR, and any NEP-141 you paste in. The pool is coin / asset on Rhea DCL; the market cap reads in dollars through the asset's price; the creator's fees arrive in the asset.

RWA. Real-world assets bridged to NEAR. Tether Gold (XAUT) today. Robinhood's stock tokens (AAPL, TSLA, NVDA, SPY, …) are listed and marked soon: Robinhood Chain is a chain NEAR already bridges from, and the stock tokens open as pair assets the moment they are listed on the bridge.

Perp-backed. Not a pair asset but a market: the coin launches in USDC and is later backed by a leveraged position on that market. See Perp-backed coins.

The registry

The factory keeps a registry of pair assets: for each one, its decimals, the default opening price, the band a creator may open inside, and whether it is enabled. A launch against an asset that is not in the registry, or is disabled, is refused by the contract. Adding an asset is an owner action; ask for one to be listed.

The depth check

The interface refuses to build a launch against an asset whose market is too thin, because a small buy in that market would move the asset's price, and the coin's chart with it.

The interface reads the asset's markets on NEAR through DexScreener and takes its deepest single pool, never the sum across venues. NEAR and USDC skip the check. Every pair asset needs a live USD price; one that cannot be priced cannot be launched against.

The check is a quality filter in the interface, not a rule in the contract: anyone calling the factory directly can launch against any asset the registry allows, however thin. Nothing in the protocol's funds depends on it.
