Vesper

The launchpad for Robinhood Chain — where a token launch starts as an NFT mint.

Website: vesperpad.world · X: @vesperpad

A creator deploys an NFT collection. When it mints out, the token launches by itself: a real Uniswap V4 market opens and the liquidity is locked forever. Minters receive a locked airdrop, and a share of the token's trade fees backs a growing NFT floor — so an active token lifts every NFT.

How it works

1. Create — deploy an NFT collection for your token (set supply and a free or paid mint, 1 per wallet).
2. Mint — people mint. On a paid mint the ETH is split floor 50% / creator 30% / dev 20%; the floor share seeds the NFT floor vault.
3. Auto-launch — on sold-out the token deploys, a Uniswap V4 ETH market opens single-sided at a fixed opening valuation (FDV ~1.8 ETH), and the LP position is burned.
4. Airdrop — 10% of supply goes to minters, locked one month; the claim is attached to the NFT.
5. Floor — every trade pays 2.5% each way, split creator 50 / vault 30 / dev 20. The vault's 30% backs the NFTs (floor = vault balance ÷ supply). The creator's 50% is held in the fee hook and paid only when the creator calls claim(); it is never auto-sent.
6. Exit — sell the NFT before claiming (buyer inherits the airdrop), or redeem it to the floor anytime after the lock. Once claimed, the NFT can only be redeemed/burned.

Contracts

Contract	Role
VesperFactory	Creates NFT collections; on sold-out, deploys the token, seeds + locks LP, wires everything
VesperNFT	ERC-721 + EIP-2981. Mint (free/paid, 1/wallet), auto-finalize, locked after airdrop claim
VesperToken	Fixed-supply (1B) ERC-20, burnable
VesperFeeHook	Shared Uniswap V4 hook; 2.5%/2.5% ETH fee split creator/vault/dev. Creator share accrues for manual claim()
FloorVault	Holds 30% of fees; redeem(tokenId) pays the floor and burns the NFT
Airdrop	Per-NFT share, 1-month cliff, claim by holder
FeeSplitter	Splits royalty / redeem fees between creator and dev

Build & test

Built with Foundry.

cd contracts
forge install foundry-rs/forge-std OpenZeppelin/openzeppelin-contracts Uniswap/v4-periphery
RH_RPC=<robinhood-chain-rpc> forge test

Remappings live in foundry.toml; v4-periphery vendors v4-core, permit2 and solmate.

Tests run against a Robinhood Chain fork (Uniswap V4 is already deployed there).

Web

cd web
node server.mjs   # serves the static site on :3096

Set window.VESPER.FACTORY in web/public/config.js to the deployed factory address to go live.

Status

Live on Robinhood Chain. Contracts deployed and the site is running at vesperpad.world.

Security & verification

This repository ships source only. Before trusting a live address, verify its on-chain bytecode against these sources. Every launch is created by the one factory above and uses the one shared fee hook — there is no per-token custom code, so what you read here is what runs.

What the code guarantees, and you can check on-chain:

• Liquidity is burned. On launch the LP position is minted straight to 0x…dEaD. There is no withdrawal path — not for the creator, not for us.
• No premine. Total supply is fixed at 1,000,000,000: 10% to minters (locked one month), 90% into the burned pool. No allocation is minted to any team wallet.
• No admin over launches. The factory has no owner switch and no upgrade path; launch parameters are constants in the source. The hook owner's only action is a one-time setFactory, after which it cannot be changed.
• Non-custodial. Every action is a transaction from your own wallet. Vesper never holds your keys or your assets.

Tokens can be volatile and can lose all their value. Nothing here is financial advice. If you find a security issue, please report it privately rather than opening a public issue.
