HudPad is a token launchpad and the .hud name service, on three chains from one site: HyperEVM (the flagship), Robinhood Chain and Stable. Every rule below is enforced by immutable contracts. No admin keys, no upgrade path, no pause.

• One launch path. A coin is born on a bonding curve in one small transaction, trades within seconds, and graduates into a real pool when the curve sells out.
• Fixed supply. 1,000,000,000 tokens minted once, with no mint function anywhere.
• Nothing can withdraw the liquidity. The raise can only become the graduated pool's locked quote side; no function returns it to anyone.
• Every coin burns itself. The coin side of pool fees is burned in full at collection, on every chain.
• Pick what it trades against. The chain's own coin, its dollar, or a tokenized stock, from a list the contract itself carries.
• Own your name. yourname.hud is an on-chain ERC-721 on HyperEVM that resolves on every HudPad board.
• Address signature. Every coin's address is mined to end in 999.

Creating

One transaction from your own wallet. The coin's address is mined beforehand to end in 999 and is created with CREATE2, so the address you are shown before you sign is the address you get. Supply is fixed at 1,000,000,000 and the creator and metadata are written once.

An optional dev buy rides inside the same transaction, which is the sniper defence: the creator's first fill happens before anything exists to front-run. For the first 120 seconds a single buy is capped at 2% of supply; the creator's own dev buy is exempt.

Trading on the curve

Buys and sells run against a constant-product curve inside the launch contract. The price opens at a fixed level and rises as the curve's stock is bought; there is no order book and no pool yet. Trades are plain wallet calls with a slippage floor, and the final buy part-fills and refunds the rest in the same transaction.

The pair

Every curve carries a list of quotes it accepts, read from the contract itself: the chain's own coin, its dollar (USDT0 on HyperEVM and Stable, USDG on Robinhood) and the tokenized stocks that chain has, which are issued by third parties and not by HudPad. A coin paired with a stock still takes the chain's own coin as payment: the contract swaps it through the pair's own route pools inside your trade. Prices, market caps and the graduation target are all shown in the pair you picked.

Graduation

Graduation is an inventory event, not a price target. The curve holds a fixed sellable stock; when the last of it is bought the curve seals, and anyone may then call migrate(). That opens a real Uniswap v3 pool at the sealed price (HyperSwap on HyperEVM, which is a Uniswap v3 fork) and deposits the reserved supply together with the entire raise. The reserve is sized so that at graduation it is worth exactly what was raised, so the pool opens balanced and the price does not jump. The site's own keeper fires the migration within about a minute, and because the call is permissionless nobody has to wait for us.

Where the fee goes

• HyperEVM · Classic: 1% of every trade, in HYPE, paid the moment the trade happens and split in thirds fixed at deployment: platform, buyback-and-burn, creator.
• HyperEVM · Dividend: 2%. The same thirds, plus 1% shared by everyone holding the coin. Holding is the stake: no staking, no lock, one claimAll.
• Robinhood Chain and Stable: 1% of every trade, split evenly between platform and creator.

The creator's share goes to the fee recipient named at creation, which defaults to the creator's own wallet. While a coin is on the curve there is nothing to claim: the money is already in that wallet. After graduation the pool's own 1% accrues to the locked position, and anyone may call collectFees, which burns the token side in full and pays the quote side to the same fixed recipients.

.hud is a name service in the ENS tradition: a readable identity for your wallet, registered on HyperEVM and resolving across every HudPad board. Each name is a fully on-chain ERC-721 — the card art is drawn by the contract, with no server and no IPFS in the loop — so it shows in any wallet and trades on any marketplace.

• Yearly rental, priced by length in HYPE with no oracle. Shorter names cost more; the exact price is quoted live as you type.
• 90-day grace after expiry before a lapsed name can be taken by anyone else.
• Serial number on chain, so the earliest names are provably the earliest.
• Resolution both ways: a target address for the name, and a primary record for the wallet, so hudpad.hud shows across the boards instead of a raw 0x….
• Secondary market. List at a price, or make an offer held in escrow with a 7-day expiry that you can cancel any time and the owner can reject outright. Accepting is pinned to the exact offerer and amount, so a swapped or lowered offer can never be accepted silently.
• One operator. The registry allows exactly one approved operator, its own market, so a name cannot be handed to a stranger's contract. Your own transfer always works.

The forum

At hudpad.com/forum, one address for all three boards. Three rooms: Announcements, General, and Support & Advice. Reading is open to everyone. Posting asks for a .hud name, which is the whole anti-spam gate, chosen over a token threshold so it costs the same to everyone. Nothing there costs gas: a post is signed by your wallet, and the signature covers the text, so a stored post cannot be edited into something you did not write. Links are limited to x.com, and images are re-encoded in your browser before upload, which strips the GPS tag a phone photo carries.

One site, three boards: hudpad.com is HyperEVM, hudpad.com/robinhood is Robinhood Chain, hudpad.com/stable is Stable. The picker in the header switches between them and your wallet session carries across. Your wallet's own network only matters when you press a button that sends a transaction.

• HyperEVM — gas is HYPE. The platform token, the buyback-and-burn and .hud names live here, and this is the only board with a second mode, Dividend.
• Robinhood Chain — gas is ETH, and the reason to launch here is the tokenized stocks: pair against NVDA, TSLA, AAPL, SPY, QQQ and two dozen more, or the USDG dollar.
• Stable — a USDT-gas L1. There is no ETH anywhere; the default pair is USDT0, so prices read in dollars with no oracle.

The contract addresses are published here when the product goes live. Until then the band on chain is a rehearsal, and the only place any address should be read from is the app itself.

Each of these is enforced by the contract code, not by a policy or a setting someone can flip.

• The liquidity principal cannot leave. No function withdraws a pool position, and none returns the curve's raise: it can only become the graduated pool's locked side.
• Fixed supply, no mint. 1,000,000,000 minted once; the token has no mint function.
• No admin keys. No owner switch, no pause, no upgrade path. Fee splits, treasury addresses and the curve's pricing constants are constructor parameters, fixed at deployment. The one thing the platform key can still do is add a pair to the list, and set the burn address once.
• Graduation is permissionless. Anyone can migrate a sealed curve. If someone tries to open the pool first at a wrong price, the contract corrects it or refuses; a refusal leaves the raise untouched and the coin migratable the moment the obstruction is gone.
• The router custodies nothing. It takes an approval for exactly the amount being sold, always pays from the caller, refunds unspent native in the same transaction, and holds no balance between calls.
• A bad fee recipient blocks only itself. Every fee leg is gas-capped and credited to a ledger if it cannot be paid, so one creator's contract wallet cannot make everyone else's trades expensive or fail.
