LĪMENlat. threshold, the stone you cross

Launch on HyperEVM. Cross into Elysium.

Every token launches straight into a Uniswap V4 pool on HyperEVM, so it trades everywhere from the first block. When Elysium goes live, its liquidity crosses the bridge and opens on the L2 at the same price.

Three stones, one passage

Every token follows the same route. The curve is real Uniswap V4 liquidity, so any wallet or aggregator can trade it. Migration is an open call that anyone can trigger, and the contracts decide where the liquidity goes.

The curve

Anyone launches a token for the price of gas. 800M tokens sit in a Uniswap V4 position priced in HYPE, from 0.0625 to 1 HYPE per million tokens. It can be bought anywhere right away.

The threshold

Once the curve is sold, trading carries on in the same pool against the last 200M tokens. Nothing has to be called and nothing pauses. The liquidity stays locked in the launchpad.

The pool

When Elysium is live, the pool's tokens and HYPE cross the official Elysium bridge in one transaction. A pool opens there at the same price and its LP is burned.

Why it waits for no one

Elysium runs the stock Arbitrum bridge and settles on HyperEVM. A contract on HyperEVM can send tokens and HYPE across and call a contract on the other side. That is all Limen needs.

How Limen works

The contracts, the curve, and the route to Elysium, written for traders and for people who read the code.

Overview

Limen is a token launchpad on HyperEVM. Every token is created inside a Uniswap V4 pool against WHYPE, with its supply placed as concentrated liquidity. That liquidity behaves like a bonding curve, and because it is a standard V4 pool, GMGN, trading bots and any V4 router can trade it from the first block without integrating Limen.

Once Elysium mainnet is live and a token has sold its curve, its liquidity moves to Elysium at the same price.

Elysium is Kinetiq's L2 for Hyperliquid: an Arbitrum Orbit chain that settles on HyperEVM, with HYPE as its gas and 100 to 200 ms blocks. Its token bridge is the standard Arbitrum one, which is what lets a HyperEVM contract move liquidity across without anyone's permission.

Token lifecycle

State	Where	What you can do
Curve	HyperEVM	Price under 1 HYPE / 1M. Buy and sell in the V4 pool, from Limen or any aggregator.
Graduated	HyperEVM	The 800M curve is sold. Trading continues in the same pool against the last 200M. The token can migrate once Elysium is live.
On Elysium	Elysium	The liquidity has crossed. Trade on Elysium. The LP is burned.

The bonding curve

Each token has a fixed supply of 1,000,000,000. At launch the launchpad opens a Uniswap V4 pool (token / WHYPE, 1% fee, no hook) and places the whole supply in it as two single-sided positions:

curve   800M tokens   from Pa = 0.0625 to Pb = 1 HYPE / 1M
beyond  200M tokens   from Pb to the top of the price range

Pb = raise / 200M = 200 / 200M
Pa = Pb / 16

A concentrated position that holds only tokens is a bonding curve: every buy moves the price up the range, and selling the full 800M raises exactly 200 HYPE. Because Pa is Pb / 16, the HYPE and tokens in the two positions always form a constant-product pool at the current price once the curve is sold. That is why migration does not move the price.

Price on the curve, in HYPE per million tokens, against tokens sold. Market cap goes from 62.5 HYPE at launch to 1,000 HYPE when the curve is sold.

There is no last buy and no pause. A buy that crosses 1 HYPE / 1M simply continues into the 200M position, in the same swap.

Graduation

A token is graduated when its pool price reaches 1 HYPE per million tokens. At that point the 800M on the curve are sold and about 200 HYPE sits in the pool. Nothing has to be called: the pool keeps trading, now against the 200M position.

If the price falls back under 1, the token is back on the curve. Graduation is a state of the price, read on-chain by isGraduated(token).

Why it trades on GMGN from block one

The pool is created on Uniswap's own V4 PoolManager on HyperEVM, with no hook and the standard 1% fee tier. GMGN, trading bots, the Uniswap app and every V4 router already know how to quote and swap it. The tests buy and sell it through the official V4 Quoter and through a router that knows nothing about Limen.

Launching costs about 580,000 gas, a buy about 130,000 and a sell about 100,000. All of it fits in a HyperEVM small block.

Migration to Elysium

Once Elysium is activated on the launchpad, anyone can call migrate(token) for a graduated token. It removes both of the launchpad's positions from the V4 pool and sends the accrued fees to the fee address. It then sends two messages through the Elysium bridge in one HyperEVM transaction:

The tokens go through the standard ERC-20 gateway. They are locked on HyperEVM and a 1:1 representation is minted on Elysium to the Limen receiver.
The HYPE goes in a retryable ticket that calls onMigration(token, amount) on the receiver. On Elysium the call comes from the launchpad's aliased address, so nobody else can fake it.

When both have arrived, the receiver wraps the HYPE, creates the V2 pair and sends the LP to 0x…dEaD. The messages can land in either order. If the HYPE arrives first, anyone can call finalize(token) once the tokens are there.

On Elysium, your token is the bridged version

The token stays native to HyperEVM. On Elysium it is the official bridge representation, with the same name, symbol and decimals, at the address returned by calculateL2TokenAddress. Holders move their own balance with the Elysium bridge. Deposits take about a minute. Withdrawals back to HyperEVM wait for the rollup's challenge period.

If a message gets stuck

A retryable that fails to run automatically, usually because the gas price bid was too low, stays claimable. Anyone can re-run it on Elysium for about seven days. Nothing is lost.

Fees

Fee	Amount	Paid by
Trade in the pool	1%	The trader, from any app or router
Bridge messages	≈ 0.0075 HYPE	Whoever calls graduate or migrate
Launching a token	gas only	The creator

The 1% is the pool's own LP fee. It accrues to the launchpad's positions, and anyone can call collectFees(token) to send it to the fee address. It is fixed in the pool and cannot change.

Permissions

The owner of the launchpad can do two things: change where fees are sent, and propose the Elysium bridge addresses once.

The proposal is checked on-chain: the router, gateway and inbox have to point at each other.
It can only be activated 24 hours later, so anyone can check it first.
Once activated, it can never change.

The owner cannot touch the pool's liquidity or the token supply. On Elysium, the receiver's owner can only sweep leftover bridge fee refunds, never HYPE reserved for a migration.

Trading was tested on a fork of HyperEVM mainnet against Uniswap's live V4 contracts. Migration was tested end to end on forks of HyperEVM testnet and Elysium testnet, against Kinetiq's live testnet bridge contracts. Elysium's mainnet bridge addresses are published by Kinetiq at launch.

Risks

The contracts have not been audited yet.
Elysium is pre-launch. Its parameters and dates can still change.
Elysium starts with a single sequencer and permissioned validation, the usual setup for a new Orbit chain.
After a migration, the HyperEVM pool no longer holds Limen's liquidity. Trading moves to Elysium.
Tokens launched here are not vetted. Anyone can launch anything.

Questions

FAQ

Short answers. The docs have the details.

Can I buy with HYPE directly in the terminal?

Yes. From the day Limen launches, every buy and sell happens in the terminal with native HYPE on HyperEVM, with no wrapping and no approval to buy.

When Elysium goes live, migrated tokens trade on their Elysium pool from the same terminal, paid in HYPE on Elysium. You can move HYPE there with the official Elysium bridge, which takes about a minute.

Can I buy on GMGN?

Yes, from the first block. Every Limen token is created inside a standard Uniswap V4 pool on HyperEVM, with no hook. GMGN, trading bots and the Uniswap app trade it like any other V4 pool, with no integration needed.

How do I get HYPE on HyperEVM?

If you hold HYPE on Hyperliquid, send it from your spot balance to HyperEVM in the Hyperliquid app. It lands at the same address. You can also swap for HYPE on any HyperEVM DEX, or withdraw it from an exchange that supports HyperEVM.

What is Elysium?

Kinetiq's L2 for Hyperliquid. It runs on Arbitrum Orbit, settles on HyperEVM, uses HYPE for gas and makes blocks every 100 to 200 ms. Its mainnet is not live yet.

What happens to my tokens when the pool moves to Elysium?

Nothing happens to your wallet. Your tokens stay on HyperEVM. Only the pool's liquidity moves. To trade on Elysium, bridge your tokens with the official Elysium bridge and you receive the same amount there.

Who triggers the migration?

Anyone. migrate is an open call. Limen runs a keeper that calls it as soon as Elysium is active and a token has graduated, but it is not required.

Can the team take the liquidity?

No. The pool's liquidity belongs to the launchpad contract, and the only function that can remove it sends it to Elysium. On Elysium the LP is burned.

Does the price jump at graduation?

No. There is no graduation transaction. The curve and the 200M beyond it are two positions in the same pool, so the price moves continuously through 1 HYPE per million tokens.

How much does it cost to launch a token?

Only gas, around 580,000 on HyperEVM. You can add a first buy in the same transaction.

What if Elysium is delayed?

Nothing breaks. Tokens keep trading in their HyperEVM pools. The migration simply happens later.

Are tokens taxed?

No. Every Limen token is a plain ERC-20 with no transfer tax. The Elysium bridge does not accept taxed tokens anyway.
