The tech
Two rails. One road to Hyperliquid.
Pay in SOL and launch on HyperEVM, or launch on pump.fun paired to HYPE. Either way, every trade feeds a listing fund that buys the coin a Hyperliquid spot listing. Everything runs on public, verified contracts.
Features
What's under the hood
Pay in SOL, launch on HyperEVM
One Solana signature. Relay bridges your SOL to HYPE on HyperEVM in seconds and PurrPad launches the coin for you. No HYPE to buy, no bridge to use, no EVM wallet to set up.
Locked liquidity
HyperEVM coins trade in a pool whose HYPE sits inside the verified contract. There's no LP token and no withdraw function, so nobody can pull the liquidity, us included.
Listing tax, locked on-chain
Every buy and sell sends 1–5% to the listing fund in the same transaction. Hyperliquid Listing mode won't let anyone change it until the coin is listed.
One wallet per launch
Every HyperEVM launch gets its own wallet, and the bridge pays only that wallet. The launch is always its first transaction, so a launch can't run twice and your funds never mix with anyone else's.
Anti-snipe and anti-whale
HyperEVM launches switch on launch protections: a snipe tax that starts at 50% and fades to zero over the first minute, and a 2%-of-supply cap per wallet for the first five minutes.
pump.fun split, locked for good
On Solana, coins launch on pump.fun paired to HYPE. Your listing share of creator fees is set with pump.fun's own fee-sharing, and its admin is revoked in the same transaction.
Live listing price
Every coin's fuel is measured against Hyperliquid's live HIP-1 spot-deploy auction, read straight from Hyperliquid. The bar shows the real price, not a guess.
No database, no custody of fees
The board is read live from Solana and HyperEVM. An hourly crank sweeps pump.fun fees with a permissionless instruction that can only pay the locked shareholders.

SOL in, a coin on Hyperliquid out
- 01
Pay
You sign one Solana transaction: a deposit of SOL to Relay's bridge program, quoted to pay out HYPE to this launch's own HyperEVM wallet.

- 02
Bridge
A Relay solver pays the HYPE out on HyperEVM within seconds. If it can't, Relay refunds your SOL on Solana and nothing launches.

Launch
The launch wallet's first transaction launches the coin in Hyperliquid Listing mode with anti-snipe and anti-whale on. It can only ever be that wallet's first transaction, so it can't happen twice.

Trade
The coin trades against HYPE in its own pool, right on its PurrPad page. Every buy and sell pays the listing tax straight to the listing fund, and the contract keeps a per-coin ledger of it.

List
When a coin's contributions cover the live HIP-1 spot-deploy auction, it shows Cleared. We bid on the listing by hand and the contract confirms it on-chain from HyperCore.

Creator fees become a listing
- 01
Launch
You launch from your own wallet, in one signature. It's a normal pump.fun coin, but its quote token is HYPE instead of SOL, so every trade is priced in HYPE.

- 02
Lock
In the same transaction, pump.fun's own fee-sharing is set: the listing fund takes your chosen share (50–100%) of creator fees. Then the admin is revoked, so nobody can change the split.

Feed
Every buy and sell pays pump.fun's creator fee in HYPE into the coin's fee vault. Once an hour our crank pushes what's waiting into the listing fund. Anyone can trigger that move.

Measure
The board reads every fee-sharing config that pays the fund straight from Solana, and credits each coin with the HYPE that came from its own vault.

List
When a coin's fuel covers the live HIP-1 spot-deploy auction, it shows Cleared. We bid on the listing with that coin's HYPE and post the receipt on the fund page.

Enforced by code
- The pump.fun fee split. pump.fun locks it at launch and nobody can redirect it.
- The HyperEVM listing tax. The contract won't let it change until the coin is listed.
- The liquidity. It sits in the pool contract, with no withdraw function.
- One launch per payment. Each launch is its own wallet's first transaction.
- The numbers. Every coin's fuel is read from chain, live, by anyone.
Where you trust us
- The listing funds are wallets we hold. They're public, but they're ours.
- Listings are bought by hand, so a listing is never guaranteed.
- HyperEVM launches are sent by our server: we run the bridge quote and the launch for you.
- A Hyperliquid spot listing is a HIP-1 token on HyperCore, not the Solana mint, so each coin's plan is posted before we bid.
