The greenhouse,
settled onchain.
Every NFT on Robinhood Chain in one place — and a launchpad that deploys your own ERC-721 in a single transaction, with fairness you can verify from across the street.

The Launchpad
Bring the seeds — one transaction deploys your own ERC-721, and mint money flows straight to you.

We build the greenhouse.
One battle-tested ERC-721, stamped out fresh for every drop — the thousandth collection runs the same code as the first. The art is pinned down before anyone mints — by on-chain code or a committed hash — the reveal is settled by a block that doesn't exist yet, and mint money walks straight from the collector's wallet into yours. Nobody in between.
Raised under this roof.
Launched through Vendra — with the fairness receipts to prove it.
Tokens
Coins that grow beside the collections.
Vendra Token
Ticker & CA — soon
Price mints in the token, gate drops to holders, and send a slice of every sale out of circulation. The token module opens alongside the launch — the contract address will appear here first.
Tokens launched beside drops will be listed here.

How the greenhouse is built.
The factory
Every collection is its own ERC-721 contract, deployed fresh by the
VendraFactory — the thousandth drop runs the same audited code as the
first. The factory keeps a public registry of everything grown here, takes no fee and
holds no funds.
Minting
Fixed supply, fixed price, up to 20 per transaction. Payment travels from the collector's wallet to the creator's wallet inside the mint transaction itself — the contract never holds a balance.
The fair reveal
Before reveal, every token shows a placeholder. The creator schedules a reveal,
committing to a block roughly 8 blocks in the future. Once that block exists, its hash
seeds the shuffle: artIndex = (tokenId − 1 + seed) mod supply + 1.
The hash did not exist at scheduling time, so nobody could aim it — and
anyone can call reveal() once the window opens, so it cannot be
quietly re-rolled either.
On-chain art
In generative mode, tokenURI builds the SVG and its metadata inside the
contract — no IPFS, no servers, nothing to keep paying for. In external mode, the
creator can commit to the art list as an on-chain hash before minting opens, and the
base URI locks forever at reveal.

How it works.
From a folder of art to a live, provably fair collection.
-
1
Connect
Any injected EVM wallet — MetaMask, Phantom and friends. Vendra switches you to Robinhood Chain automatically.
-
2
Plant
Name, symbol, supply, price, art mode. One signature deploys your own ERC-721 through the factory. You are the owner — not us.
-
3
Mint
Share your drop page. Collectors mint straight from the contract and every wei of the mint price lands in your wallet in the same transaction.

Reveal
Schedule the reveal; a future blockhash shuffles the art. Anyone can trigger it once the window opens — that is what keeps it honest.
