How Vein's instant liquidity, flexible pairing, and holder rewards actually work.

What is Vein

Vein is an instant-liquidity launchpad on HyperEVM. Launch a coin and its entire supply becomes tradeable on PRJX in the same transaction — no bonding curve, no threshold to cross, no waiting to graduate.

What makes Vein different: you can pair a new coin against any token already trading on PRJX, not just HYPE — and every trade still pays every current holder a share, automatically tracked and claimable in HYPE.

How it works

01
Pick any quote asset

Launch paired against HYPE, or any other token that already has real liquidity against HYPE on PRJX. Vein verifies this on-chain before allowing the launch - never assumed.

02
Full supply, instantly liquid

One transaction mints the entire 1,000,000,000 supply directly into a locked PRJX position. It trades like a normal pair from the very first block - there's nothing to graduate.

03
Every holder earns, claimable in HYPE

A 3% fee on every transfer is tracked per holder in real time and paid out in HYPE. Claim any time from the coin's page or your Dashboard.

Quote assets

Most launchpads only let you pair a new coin against one fixed asset. Vein lets you pair against anything already trading on PRJX, as long as it clears one check:

The rule Either the quote asset IS HYPE, or a real, liquid HYPE pool already exists for it on PRJX. This is checked on-chain at launch - not assumed, not admin-curated.

This same rule is what makes pricing and rewards work no matter what you pair against: since every quote asset can be traced back to HYPE, Vein can always resolve a USD price for market cap, and always route harvested fees back to HYPE for holders and creators.

Fees & rewards

Every transfer of a Vein coin - including every buy and sell through its pool - pays a 3% fee, built directly into the token contract.

Why the reward is always HYPE, not the coin itself

Fees accumulate in the coin being traded, since that's the only asset a transfer-based fee can ever collect. Anyone can call a public harvest() function that swaps this accumulated fee into HYPE through PRJX, before it's split and credited to holders and the creator - so what you actually claim is always HYPE, regardless of what the coin is paired against.

Rewards accrue automatically, but don't move on their own Your claimable balance updates in real time as trades happen. Actually receiving it into your wallet still takes one transaction - claim any time from the coin's page or your Dashboard.

Risks

Coins launched on Vein are created permissionlessly by anyone, including anonymous creators. Vein does not vet, audit, or endorse any individual coin. The liquidity position being locked forever means it can't be pulled by the creator - it does not mean the coin is safe, valuable, or free of other risks.

Pairing against a token other than HYPE means a coin's price is also exposed to that quote asset's own price movements. Trade at your own risk.
