How it works

Launch, trade and verify tokens. Built to keep liquidity locked.

LittleJohn combines a token launchpad, a Uniswap v4 trading terminal and transparent on-chain safety checks. Every launch has a fixed supply, immutable configuration and a dedicated liquidity NFT locker.

01 · LAUNCH

Two ways to enter the market

Every Custom Launch and Fair Launch pays the same fixed 0.0045 ETH anti-spam fee, plus network gas. The amount is shown before signing. Both modes create a real Uniswap v4 pool and lock the liquidity position from launch.

CUSTOM LAUNCH

You set the opening market cap

Best when you already have a launch plan and want the open market to start immediately.

  • Tradeable as soon as the launch confirms
  • Creator-selected starting market cap
  • Locked liquidity from block one
FAIR LAUNCH

The market discovers the price

Best for an organic launch where early demand establishes price inside the same live pool.

  • No starting market cap to configure
  • Graduation is a milestone, not a migration
  • Trading does not pause at graduation

02 · CONFIGURE

Choose the trading fee that fits your launch

The creator chooses a base trading fee from 1% to 5%. That choice is recorded at launch and cannot be raised later. A lower fee reduces trading friction; a higher fee increases the ETH earned per trade for the creator and protocol.

OPTIONAL OPENING PROTECTION

Anti-snipe starts high, then settles automatically

Enable an opening window that can begin as high as 40%. The fee decays during the first seconds until it reaches the selected 1% to 5% base fee. This makes automated opening-block sniping more expensive without changing the long-term fee.

  • Optional for both launch modes
  • Maximum opening fee is capped at 40%
  • Automatically settles at the immutable base fee
  • Same published rules apply to every wallet

03 · LOCK

Where the liquidity NFT goes

A Uniswap v4 liquidity position is represented by a PositionManager NFT. LittleJohn places that NFT inside a dedicated locker contract. The creator never receives or controls it.

  1. 01
    Pool created

    The token and ETH enter a live Uniswap v4 pool.

  2. 02
    NFT locked

    The PositionManager NFT is owned by the dedicated locker.

  3. 03
    Trading stays live

    Liquidity cannot be decreased, transferred, approved or burned.

  4. 04
    Fees remain collectable

    Only earned fees can leave, never the locked principal.

VERIFIED LIQUIDITY LOCKER

Shown only after source verification, expected bytecode, NFT ownership and immutable configuration all pass.

VERIFICATION PENDING

The evidence is still being completed. It is not presented as verified until every check succeeds.

See every verification check
  • Blockscout source code verified
  • Expected frozen locker bytecode
  • ownerOf(positionTokenId) == locker
  • Correct PoolManager and PositionManager
  • Protocol share fixed at 33.33%
  • Creator and protocol recipients immutable

Token pages provide direct explorer links to both the locker contract and the PositionManager NFT, so anyone can verify the proof independently.

04 · EARN

Creators receive two thirds of every trading fee

Fees accrue on-chain to the locker as trades happen. Collection is permissionless: LittleJohn's keeper can trigger it automatically, and anyone can call the same public collection function. Collection never unlocks or removes liquidity.

What if a recipient cannot receive the ETH?

The amount falls back to recipient-only escrow. Only the immutable recipient wallet can withdraw its share, and the collector or keeper cannot redirect it.

06 · UNDERSTAND THE PROTECTION

Liquidity-rug resistant by construction

What the contracts prevent

  • Removing the locked liquidity principal
  • Transferring or approving the liquidity NFT
  • Minting additional token supply
  • Raising the selected base trading fee
  • Using owner controls to disable public transfers

What locking cannot prevent

  • Token prices falling because of market activity
  • A holder selling tokens they legitimately own
  • Wallet, bridge or third-party interface risk
  • Unknown smart-contract or chain-level risk
FAQ

The details, without the fine-print maze

Can the creator remove the liquidity NFT?

No. The dedicated locker owns the PositionManager NFT and exposes no route to transfer, approve, burn or use it to decrease liquidity.

Can fees still be collected if the NFT is locked?

Yes. Fee collection uses zero liquidity removal. Anyone can trigger collection, but the ETH can only flow to the immutable creator and protocol recipients.

What does Verification pending mean?

It means the explorer source or one of the on-chain evidence checks is not complete yet. The UI only shows Verified liquidity locker after every required check passes.

Can I choose a different trading fee?

Yes. Choose a base fee from 1% to 5% before launch. It becomes immutable after deployment. Anti-snipe is optional and only affects the opening window before settling at that base fee.

Where can the pool be traded?

The launch creates a live Uniswap v4 pool on Robinhood Chain. LittleJohn provides its own swap route and terminal; availability in third-party interfaces depends on their chain and hook support.

Does locked liquidity mean the token price cannot fall?

No. Locked liquidity prevents the liquidity principal from being withdrawn. Price still moves with buys, sells and market demand.
