Build a DEX

A hosted exchange over Gully Core pools, with your name and brand. It is the same contract as a Launchpad. Only what the site shows changes.

What a DEX is

There is no separate contract for a DEX. A DEX is a GullyCorePad whose brand says kind: "dex", or "both" for a site that launches tokens and trades them. The kind only changes what the hosted site at /p/<your-site> renders: a swap box, markets, charts and pool pages. Ownership, admins and the free address work as on Build a Launchpad.

Create one at Build a DEX.

Which pools it lists

Scope	Markets shown
`launches`	Pools of tokens launched through your site
`all`	Every Gully Core pool on the chain

The owner may hide a token. Every pool that trades it leaves the site's markets, ticker and swap box.
The owner may feature launches at the top of the site.
A token's own icon is drawn from its on-chain metadata. A token that names none gets a monogram.

Router

Your site's swap box uses Gully Core's router with no configuration: best price across Gully Core pools and the other venues it routes through. See Router. The routing fee applies only to a fill routed to another venue, not to a Gully Core pool. Your share as a site comes from launches, not from routed trades.

A site built from a white-label template may point at its own router instead. It then neither pays nor collects Gully Core's routing fee, and owns that router's security.

Fees

On pools your DEX creates, Gully takes a flat 0.30% of every trade and nothing else. Gully's own apps follow separate terms. See Fees.

Custom domain

A free <label>.pads.gullychain.xyz address now. Your own domain is coming soon. The details are on Build a Launchpad.

Build a stock market

A stock market is the same GullyCorePad with kind: "stocks". See Stock market.

Site fee

Creating a DEX costs the same flat site fee as a Launchpad: about $25 in the chain's native coin on each chain, set by governance inside an immutable cap and read from the contract. An increase takes effect only after a public notice period. Anything sent above the fee is refunded. The app shows the exact amount before you sign.
