Documentation
Debut is an NFT launchpad on Robinhood Chain. A project deploys its own ERC-721A contract through the factory, sets its own mint stages, and keeps ownership of the contract, the royalties and the proceeds, less the platform fee below. Debut never takes custody of a collection, its metadata or its funds.

The source of every contract above is published and verified on Sourcify, an independent verification service, so the bytecode running on chain can be compiled from the published source and compared byte for byte. Anything stated on this page can be checked against it rather than taken on trust. The block explorer's own verification API is behind a bot challenge that refuses automated submission, so the source is not yet mirrored there.
How a drop works
Stages
A drop holds an ordered list of stages. Each has a name, a price, a start and end time, a per-wallet cap, and optionally its own slice of the supply. Per-wallet limits are counted per stage, so an allowlist mint never eats into somebody's public allocation. A stage with no end time runs until the collection sells out.
Stages are not a promise. The creator owns the contract, so they can rewrite a stage's price, window, caps, allowlist or gate at any time, including while it is minting, and they can mint to themselves for free up to the collection's maximum supply without going through a stage at all. Those two powers are ordinary for an NFT contract and the creator needs them, but they mean a stage's terms describe what is true now, not what is guaranteed. Check the contract if the difference matters to you.
Allowlists
Only a merkle root and a URL go on chain, never the addresses themselves. The creator pastes addresses into the launch form, which builds the root in the browser and hands back a JSON file. Publishing that file is the creator's own job: Debut has no server and hosts nothing, so the file needs somewhere public, such as IPFS or any static host, and its URL goes into the stage. Before a launch, the form fetches that URL, rebuilds the root from what it finds and refuses to deploy unless the two match. A minter's browser then fetches the same list, rebuilds the tree and generates its own proof. An entry can carry a personal allocation, written as 0xabc..., 3. That allocation is part of the leaf, so a wallet cannot claim a bigger one than it was granted, and the leaf binds to the caller, so a proof cannot be reused by another wallet.
Declining price
A stage can fall from a start price to a floor across its window. The mint charges the price in the block it lands in and refunds any surplus, so a quote going stale between signing and confirmation costs nothing.
Token gates
A stage can require holding a minimum balance of another NFT collection, for holder-only mints.
Reveal
Token metadata resolves to baseURI + tokenId + .json, starting at token 1. The suffix is what a drop launched here uses; the contract itself lets the creator set a different one. Ship a placeholder URI for a delayed reveal and every token serves it until the creator reveals. Freezing metadata locks the URIs permanently and cannot be undone.
Money and control
- Mint proceeds sit in the drop contract until withdrawal, which splits the balance between the creator's payout address and the platform fee recipient in one transaction.
- Fee terms are burned into each drop when it is created. Changing the platform fee later cannot touch drops that already exist, and the factory caps the fee at 10%.
- The factory sets the drop's owner to whoever created it, whatever the payload says. The platform can pause new launches; it can never touch an existing collection, its metadata, or its funds.
- Withdrawal is callable by anyone, because it can only ever move funds to the collection's payout address and the platform fee recipient, never to whoever calls it. The fee recipient and the fee itself are fixed at deployment. The payout address is not: the creator can change it at any time.
- Royalties are published via EIP-2981 and honoured at each marketplace's discretion. The creator can change or remove them at any time.
Risks
- Supply can be reduced by a creator but never increased, and never below what is already minted.
- If a creator sets an allowlist root but never publishes a reachable address list, nobody can build a proof and that stage cannot be minted through this site.
- Collection art and metadata are hosted by the creator. Debut does not pin, mirror or guarantee them.
- Anyone can deploy a collection here. A listing is not an endorsement, and nothing on this site is a recommendation to buy.
About
Debut is an independent project. It is not affiliated with, endorsed by, or connected to Robinhood Markets. It runs on Robinhood Chain, a public network that anyone may deploy to.
