HudPad is a token launchpad on seven chains from one site: HyperEVM (the flagship), ETH, Base, Robinhood, BNB, Arc and Stable. The .hud name service is on HyperEVM and resolves everywhere. Every rule below is enforced by immutable contracts. No admin keys, no upgrade path, no pause.

• One way to launch, on every chain. A coin opens straight into a pool on its chain's own exchange (Project X on HyperEVM, Uniswap v4 on ETH and Arc, Uniswap v3 on Robinhood and Stable, PancakeSwap v3 on BNB), priced in the pair you pick, with its whole supply placed as liquidity above the opening price. A first buy is yours to make or to skip: leave it empty and the pool is live for whoever comes first.
• Fixed supply. 1,000,000,000 tokens minted once, with no mint function anywhere.
• Nothing can withdraw the liquidity. The whole supply is placed as one position and held by the locker contract, as the venue's own position NFT (on ETH and Arc, Uniswap v4's). It has no function to take it out, and what buyers bring stays in the pool.
• HUD burns. HUD buys itself back off the open market and burns what it buys. On HyperEVM 20% of the fee on HyperEVM pairs is set aside for that buyback, and every coin's fee burns its own coin side.
• Pick what it trades against. The chain's own coin, its dollars, a tokenized stock, a commodity token or, on HyperEVM, a Hyperliquid spot or perp pair, from the quote book the chain carries. A pair is added to the book by listing; no new contracts, and nothing about a coin already born changes.
• One coin on several chains. An Omni launch opens the same coin at the same address on every chain you pick. Each chain has its own pool and its own price, and Move carries coins between them.
• 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.
• Older coins keep their rules. A coin born before 16 September 2026 on a bonding curve trades on its curve until it sells out and graduates as before; nothing about it changed.

Creating

One transaction from your own wallet on ETH, Robinhood, BNB, Arc and Stable; two steps on HyperEVM (below). 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 the metadata are written once.

The first buy is optional. Put an amount in and it is filled inside the launch, before anyone else can trade, which is the sniper defence. Leave it empty and the pool opens with nothing bought, at the same price, live for whoever comes first.

What you set at launch

Four things, written into the coin once. Holder rewards: a share of your own fee cut (10, 25 or 50%, or none) goes to everyone holding the coin, streamed to them over six hours, no staking and no lock, one claim on the profile; it can be raised later by you or your fee recipient, never lowered. Snipe guard: written into the coin itself. In its launch block no wallet can receive the coin, so the opening belongs to the first buy alone; after that, until the guard ends (60 seconds by default, off, or up to five minutes), no wallet may hold more than 1% of the supply. The pool, the router and the locker are exempt, and selling is never touched. On Robinhood the launch block is Ethereum's, about twelve seconds. Fees go to your wallet, another wallet, or a fixed split of 2 to 20 wallets: the split is a small contract pressed at its predicted address in the same launch, and its list never changes. The pool fee is the 1% tier. A launch fee of about a quarter dollar in the chain's coin goes to the platform with the transaction.

The pair and the opening

Every chain carries a quote book, a contract listing what a coin may be priced in: the chain's own coin, its dollars (USDC on HyperEVM and Arc, USDC, DAI and their twins on ETH, USDG on Robinhood, USDT and its twins on BNB, USDT0 on Stable), the tokenized stocks and commodities a chain has, and on HyperEVM the Hyperliquid spot and perp pairs, a perp pair being a leveraged token from 2x to 5x, long or short. Stocks and leveraged tokens are issued by third parties, not by HudPad. Whatever the pair, you pay in the chain's own coin: the launcher swaps it along the pair's route inside your transaction. Every coin opens at the same fixed dollar size, priced into its pair at launch and shown on the launch page before you sign, so market caps read alike across pairs and chains.

The pool

The pool is on the chain's own exchange (Project X on HyperEVM, Uniswap v4 on ETH and Arc, Uniswap v3 on Robinhood and Stable, PancakeSwap v3 on BNB), the 1% fee tier, opened at the coin's price with the supply as one-sided liquidity above it. The locker holds the position as the venue's position NFT (on ETH and Arc through Uniswap v4's position manager, with no hook on the pool): there is no function to move it, and the fees it earns are collected into the chain's escrow (below). Trades run through the chain's router, from your wallet, with a slippage floor read off the router's own answer.

Launching on HyperEVM

Building a pool does not fit in a HyperEVM small block, so a launch there takes two steps. Your transaction, request, holds the deposit and records the launch. The site then sends open in the next big block, about a minute later, which builds exactly the recorded launch for you; open is permissionless and gives whoever sends it nothing. If the launch cannot be built within ten minutes, refund sends the deposit back to its creator; that too is anyone's press, and pays only the creator.

Coins born before 16 September 2026

Those launched on a bonding curve. The curve holds a fixed sellable stock; when the last of it is bought the curve seals and anyone may call migrate(), which opens a real pool at the sealed price and deposits the reserve together with the raise. Buys and sells on a curve are plain wallet calls against the curve contract, with a slippage floor, the final buy part-filling and refunding the rest. Robinhood's earlier direct coins live in Uniswap v4 pools behind a fee hook. Each of these coins trades through the router of the band it was born on; the site knows which.

Where the fee goes

Every pool charges 1% on each swap, on both sides. The pair side is split the way the quote book pins for that pair the moment the coin is born, and never changes for it; the coin side is burned.

• HyperEVM pairs (HYPE, HyperEVM tokens, the stock wrappers): 60% to the creator, 20% to the platform, 20% to HUD's buyback-and-burn.
• HyperEVM spot and perp pairs: 70% to the creator, 30% to the platform, no burn share.
• ETH, Robinhood, BNB, Arc and Stable: 70% to the creator, 30% to the platform. There is no buyback leg on these chains: the burner lives on HyperEVM, where HUD's pool is.
• Holder rewards, any chain: the share the creator set at launch comes out of the creator's cut and goes to everyone holding the coin, streamed over six hours by the chain's holders' vault; the platform's share is untouched by it.
• Older curve coins: HyperEVM 60 / 20 / 20 on a 1% fee (2% on a Dividend coin, half of it to holders); Robinhood and Stable 65% creator, 35% platform; the creator tax and the snipe tax were the curve's and do not exist on the pool launch.

The creator's share goes to the fee recipient named at creation, which defaults to the creator's own wallet and can be handed on by whoever holds it. It is recorded in the chain's escrow rather than sent: every share is written under that address and stays there until its owner takes it. The escrow also keeps what each address has earned and taken out, so the figures on a profile are one read of the chain, not a scan of its history. One claim on the profile (collectAndClaim) takes your lines in the escrow and your streamed share in the holders' vault together, and anyone may press it for you: it pays only you.

That is what makes the money safe to hold. A claim pays the caller and nobody else, so no other recipient's behaviour can hold up yours, and nothing can be sent to an address that refuses it. The escrow keeps one balance per asset, not one per coin: ten coins paired against the same asset share a single balance, and one claim takes all of it. Each band of contracts has its own escrow on its chain; a creator with coins on two bands, or two chains, claims each, and the profile lists every one.

A pool holds the fees it charges until somebody moves them into the escrow. That move, collectPoolFees on the coin's launcher, is open to anyone and pays nobody for doing it; the pair side splits as above and the coin side burns in the same transaction. HUD's own pool is collected the same way, its coin side burned outright. A Robinhood coin from the earlier v4 band holds its fees in its hook until sweep shares them out.

An Omni launch opens the same coin at the same address on every chain you pick, up to all six. You launch on one chain, the centre; a LayerZero message opens the coin on each other chain in the same move, with no opening buy there. The supply is split into slices (equal, 55% to the centre, or your own), and each chain holds its slice in its own pool, opened where that slice is worth a whole one-chain opening: every pool is as deep as a one-chain launch, so a buy moves an Omni coin no further than it would move any coin. Equal slices on three chains open at three times a one-chain opening; a bigger slice opens lower than a smaller one.

• Each chain has its own pool and its own price. Nothing on chain keeps them equal; trades between the chains do. A pool is one-sided above its opening, so no chain trades below its own opening price. The coin's page lists every chain's price side by side.
• Move carries your coins from one chain to another: burned where they leave and minted where they land, over LayerZero, with its verifiers fixed at the coin's birth and no owner.
• The launch fee is paid once for each chain, and the messages' fee rides with the launch; both are shown before you sign.
• The fee split, the holder share and the snipe guard work as in a one-chain launch, on every chain the coin opens on, each chain's split pinned from its own quote book.
• On HyperEVM an Omni coin opens in a big block like any launch there: the site sends open when HyperEVM is the centre, and openPending when the coin's message lands there from another chain.

.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, at a fixed dollar price by length (three letters, four, five and up), paid in HYPE at the rate the contract reads at that moment. 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 every chain. 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, seven chains: the home shows every chain's coins, each card in its chain's colour, and the chips over the coins narrow it to one (hudpad.com/?chain=arc). A coin's page carries its chain in its address (/arc/coin/…), because the same address can hold a different coin on two chains. The launch page asks which chain; your wallet's own network only matters when you press a button that sends a transaction. The launch is the same everywhere: the quote book, the pool, an optional first buy.

• HyperEVM: gas is HYPE, the venue Project X. HUD, its buyback-and-burn and .hud names live here. The widest book: HYPE, USDC, the stock wrappers, Hyperliquid spot assets and perp pairs. A launch is two steps, request and open.
• ETH: gas is ETH, the venue Uniswap v4. The book carries ETH, its dollars and the euro, gold and silver, tokenized shares and ETFs issued by Ondo (third-party tokens that track a share and are not the share), and the chain's crypto and memes.
• Robinhood: gas is ETH, and the reason to launch here is the stock coins: pair against tokens tracking NVDA, TSLA, AAPL, SPY, QQQ and two dozen more, or the USDG dollar. These tokens are issued by third parties and are not shares; HudPad neither issues them nor offers the shares they track.
• BNB: gas is BNB, the venue PancakeSwap v3. The book carries the chain's dollars (USDT, USDC, USD1, FDUSD, USDe, U), BTCB, ETH, SOL, XRP, DOGE, CAKE, ASTER, Tether Gold and nineteen Robinhood-issued B-shares (NVDAB, TSLAB, AAPLB, SPYB and the rest), third-party tokens that track a share and are not the share.
• Stable: a USDT-gas L1. There is no ETH anywhere; the pair is USDT0, so prices read in dollars with no oracle.
• Arc: USDC is the chain's coin, so every pair and every price reads in dollars, and gas is paid in dollars too; the venue is Uniswap v4.

Every address above is read from the live deployment registry at render time.

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

• The liquidity principal cannot leave. The locker holds every position a launch opens, one-chain and Omni alike, and has no function to withdraw one; an older curve's raise can only become its graduated pool's locked side.
• Fixed supply, no mint. 1,000,000,000 minted once; the token has no mint function.
• No admin keys on the money. No owner switch, no pause, no upgrade path. Fee splits, treasury addresses and every pool parameter are constructor arguments, fixed at deployment. The one thing a key still touches is the quote book: HudPad's deployer can list a new pair with its split, the platform's take capped at 40% by the contract, or close and reopen a pair to new launches; a listed split never changes. It cannot change a coin already born (its split is pinned at launch), cannot reach a pool, and cannot move anyone's money. HUD's genesis zeroes its own owner in the transaction that creates it, and the burner it builds can only ever spend its own balance on HUD.
• A requested launch has two outcomes. On HyperEVM the deposit a request holds can only become the recorded coin, built for its creator, or go back to the creator through refund. The recorded parameters cannot be changed, and a request is opened or refunded once.
• 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 share is recorded in the escrow rather than pushed, so one creator's contract wallet cannot make anyone else's trade or claim fail.
• Graduation of an older curve coin is permissionless, and cannot be held hostage. Anyone can migrate a sealed curve. If someone opens the pool first at a wrong price, the migration moves to the next fee tier the exchange offers; if every tier is blocked for a day, the curve thaws instead and sells are paid out of the raise.

• A requested HyperEVM launch cannot be built. If someone opens that coin's pool first at another price, or the pair moves past the launch's floor, open refuses. The deposit waits in the launcher and goes back to its creator after ten minutes; the site sends the refund itself.
• Nobody buys. A coin launched without a first buy sits at its opening price with the whole supply in the pool. Nothing is owed and nothing is lost; the first buyer sets it moving.
• A creator's fee recipient is a contract that refuses money. Its share is credited to the escrow instead of pushed, so it blocks nobody's trade but its own claim.
• A stock, dollar or perp pair's issuer pauses or restricts the asset. The coin's price is in that asset and its trades route through that asset's pools; HudPad controls none of that. The quote book carries an enabled flag that only stops new coins on that pair; coins already born keep trading.
• A pair's pool is thin. A large buy paid in the chain's coin sweeps the pair's own pool and can move it past its slippage band; the trade then waits for the market to refill, which is the protection working.
• An older curve coin sells out and nobody migrates. Nothing is lost: the raise sits in the immutable curve and the coin is migratable by anyone, a week later as easily as a minute later. The site fires the migration itself. If someone opens the pool first at a wrong price, the migration moves to the next fee tier; if every tier is blocked for a day, the curve thaws and sells are paid out of the raise.
• This site is down. The contracts are on chain and work without it: the launcher's launch, the router's buy and sell, the escrow's claim, from any wallet or explorer.
• A coin, a name or a post is not what it says. Names, tickers and images are user-written and unverified. Check the address on the explorer, and read the Terms.

Bots, dashboards and indexers integrate with the contracts, not with this site. The /api paths hudpad.com calls exist for its own pages, are sized for them and change without notice; the chain is the interface that does not. Every address is listed under Chains and contracts.

Events

• The launcher emits Launched when a coin is born: the coin, its market (the pool, or on ETH and Arc the Uniswap v4 pool id), its creator, its pair, the opening tick, the platform, burn and holder shares, the fee recipient and when its guard ends; the name, symbol and metadata are the coin's own getters. On HyperEVM a launch also emits LaunchRequested, then LaunchOpened or LaunchRefunded.
• An Omni launcher emits the same Launched on every chain the coin opens on, and on the centre OmniLaunched with the coin's chains and slices and OpenSent for each message; a message waiting on HyperEVM for its big block is OpenPending.
• On ETH and Arc the opening buy and every trade are the pool manager's Swap events for the coin's pool id.
• FeesCollected on a pool's collect, with the holders', creator, platform and burn cuts; in the escrow Credited, Claimed and PlatformSharePushed; in the holders' vault RewardAdded and Claimed.
• The quote book emits QuoteListed and QuoteEnabledSet as pairs are listed, closed or reopened.
• Older curve coins: CurveCreated, CurveTrade with the curve's reserves after the trade, FeeSettled, CurveFrozen, Graduated(token, pool, quoteIn, tokensIn) and CurveThawed; Robinhood's earlier v4 coins add PoolOpened, FeeTaken and FeesSwept on their hook.

Reading state

The quote book answers all() for every pair with its category and split, quoteOf(asset), launchable(asset) and native(); a pair asset's route travels in the call, not in the book. The launcher keeps coinOf(token) (creator, fee recipient, pair, the position and the pinned split), poolOf(token), marketOf(token) and feeRecipientOf(token); the router's poolOf(token) and marketFor(token) name the pool and pair it trades. The escrow keeps claimableOf, claimedOf and earnedOf per address and asset; the vault keeps pending(coin, holder). Older curves keep coins(token), priceX18 and progressBps, with a read-only Lens beside each.

Quoting a trade

A coin is quoted by its pool: simulate the router's buy, buyWithNative, sell or sellForNative with eth_call to read the exact output, which is what this site does, and pass a minOut floor; the router reverts rather than fill below it. An older curve coin is arithmetic on the reserves the last CurveTrade reported.

Errors

Reverts are custom errors, not strings: QuoteNotListed, NoRoute, TokenAboveQuote, BadParams, LaunchBlock, OverCap, SlippageOut, TooLittleOut, PoolPreInitialized, NotWaiting, TooEarly, NothingToClaim among them. Decode them from the ABI rather than matching text.
