Build a Launchpad

A launch site of your own on the shared core: your name, your brand, your share of every launch made through it. No contracts to deploy and nothing to host.

What a Launchpad is

A Launchpad is a GullyCorePad: a small contract cloned for you by GullyCorePadFactory. It is your tenant on the launch kit. It holds your terms and your brand on chain. The hosted site at /p/<your-launchpad> reads everything from it live, so the site needs no server of yours and no configuration file.

Launches made through your site go through the same kit, the same guards and the same lockers as every other launch on Gully Core. They get the same protections and the same "Locked by Gully Core" badge, and they trade on every DEX built on the core. See Launch a token.

Create one

Open Build a Launchpad. The builder shows a live preview of your site, saves your progress as you type, and creates the Launchpad in one transaction that also pays the site fee. Choose the chains it should live on. Each is its own transaction and its own fee.

Your terms

Every launch through your Launchpad carries the terms you set, frozen into that launch at creation.

Term	What it does	Bound
Integrator share	Your share of each launch's trade fees and of its locked liquidity's fees	set by the kit's rules
Launch fee	A flat native fee you charge per launch, paid to your wallet	inside the kit's cap
Tax cap	The highest creator tax a launch through you may set. 0 allows none	at most 10%
Tax share	Your share of any creator tax	set by the kit's rules
Quotes	The quote currencies your site offers	none

On a chain with launch kit release 3, Gully takes a flat 0.30% of every trade on your Launchpad's pools and nothing else. There is no share of the trade fee or of any tax, and no launch fee. See Fees. A launch must restate your terms exactly, so you cannot re-price a launch someone is already preparing.

Brand and themes

Name, tagline, logo, accent colour, links and one of the theme packs are stored on chain in the Launchpad's metadata, and the site renders them. The site's kind is part of the brand too: launchpad, dex or both (see Build a DEX). A site may mark itself a demo. It then wears a "Demo" tag.

Each site installs as its own app on a phone, with an icon drawn from its monogram and theme colours.

Custom domain

A free address: claim one <label>.pads.gullychain.xyz per Launchpad per chain from the site's Admin tab.
Your own domain: coming soon. It will take two halves that must agree: the brand's customDomain on chain, and DNS records only the domain's holder can create (a TXT proof and a CNAME). You can claim the hostname and publish the TXT record now. Nothing is served on your domain before it opens.

Owner and admins

Role	Can	Cannot
Owner (on chain)	Set terms, name and brand. Transfer the Launchpad (two-step). Rescue tokens sent to it by mistake	Touch any launch, lock or fee credit, or the kit. Renounce (it reverts)
Admins (hosted)	Edit the announcement, hide or feature launches	Sign anything on chain
Gully Core	Nothing on your Launchpad	Hold, change or pause it

Admins sign in with their wallet (a signature, no transaction) and are appointed by the owner. The owner role is read from the contract's owner() at sign-in.

More than one chain

Each chain has its own factory address, in the address book. See Contracts. A Launchpad's address is derived from the factory, your wallet and a value you choose, so nobody else can take it. On chains that share a factory address your Launchpad has the same address. Where the factories differ, as on Anubis and Gully Chain Testnet, it does not. Brand and terms are stored per chain. The owner tab edits once and prepares one transaction per chain. Use only chains where Gully Core is deployed. See Chains.

Site fee

Creating a Launchpad or DEX costs a flat fee of about $25 in the chain's native coin, on each chain you put it on. The fee is Gully Core's spam filter. There is no discount and no tenant share. Governance sets it in native units inside an immutable cap and re-prices it by hand. An increase takes effect only after a public notice period, a decrease at once. Anything sent above the fee is refunded in the same transaction.

The exact amount is read from the contract (padFeeWei(), maxPadFeeWei() and padFeeNoticeSeconds() on GullyCorePadFactory) and the app shows it before you sign.
