Your coin's own contract
Every coin launched here is a PairToken, and every one of them shows as verified without anyone
submitting it. That is not a courtesy — PairToken takes no constructor arguments (it calls back
into the launchpad for its name, symbol and supply), so the creation bytecode is byte-identical
every time. One instance was verified; the explorer matches all the others, including coins that do
not exist yet.
What that verified source says, and what it therefore cannot do: fixed supply set once in the constructor, no mint function, no transfer tax, no blacklist, no pause, no owner.

Calls worth knowing
Before launching
// Non-reverting. Returns whether it would be allowed, and why not if not.
registry.status(address quote)
returns (bool eligible, Decision decision, Report report)
// The bar this particular asset has to clear — $10,000 if listed, $25,000 if not.
registry.requiredDepthUsdE8(address quote) returns (uint256)
Launching
launchpad.launch(LaunchConfig cfg) payable returns (address token, address pool)
launchpad.predictToken(address creator, bytes32 salt) returns (address)
launchpad.launchFee() returns (uint256)
LaunchConfig carries, beyond the obvious:
| field | what it does |
|---|---|
creatorBps | share of supply kept back for you, capped at 20% |
feeRoute | 0 keeps your fees, 1 buys the coin back and burns it |
feeRecipient | zero means the launching wallet |
devBuyQuote | pair-asset amount spent buying your own coin as the pool's first trade; needs an approval to the launchpad first |
devBuyMinOut | least you will accept from that buy — nobody can front-run it, so this guards against you and the pool disagreeing on the opening price |
After launching
// Anyone can call. Proceeds only ever reach the recorded recipient, the sink and the treasury.
feeVault.collect(address token)
// Creator only. Both take effect from the next collect.
feeVault.setFeeRoute(address token, FeeRoute route)
feeVault.setFeeRecipient(address token, address recipient)
// Reads
launchpad.launchOf(address token) // a public mapping: an unnamed tuple
feeVault.launchOf(address token) returns (Launch) // includes the pool address
feeVault.positionOf(address token) returns (liquidity, owed0, owed1)
feeVault.feeRouteOf(address token) returns (FeeRoute)
feeVault.feeRecipientOf(address token) returns (address)
feeVault.owed(address token, address who) returns (uint256) // a payout that could not be pushed
feeVault.claim(address token) // collect one
Where the liquidity lock actually lives
There is no lock contract and no locked LP token. A Uniswap V3 position only becomes an NFT when
Uniswap's position manager wraps it; underneath it is a slot in the pool keyed by
(owner, tickLower, tickUpper), and the fee vault minted into that slot directly. The usual
"liquidity locked" detectors look for LP tokens or position NFTs sent to a burn address or a locker,
and here there is nothing of the sort for them to find.
What holds instead is a property of FeeVault, and with its source published you can check it
rather than believe it: no code path in the vault ever calls burn with a non-zero amount.
Collecting fees calls burn with exactly zero — which only moves earned fees into the position's
tokensOwed — and then collect. There is no withdraw, no emergency exit, and no owner function
that adds one. Anyone can read the position with pool.positions(keccak256(abi.encodePacked(feeVault, tickLower, tickUpper))). The float cannot come back out — not by the creator, not by us.
Owner powers
The owner can retune the depth bars, the fee bounds, the launch fee, the treasury, the buyback sink, the curated list, the gates and their parameters. It cannot touch a launch's liquidity, change an existing launch's creator share, or redirect a creator's fees.
Ownership transfer is two-step everywhere: a handover that is never accepted leaves the current owner in place rather than sending the protocol to a wrong address.
Today the owner is a single EOA. It should be a multisig behind a timelock, and the contracts do not enforce that themselves.
None of this has been audited.
