Contracts

Not deployed yet. ArcadeFun targets Sonic, chain ID 146. The contracts below are written and tested against live Sonic state; when they are deployed their addresses go in this table, each verified on Sonicscan so the code behind the link is the code that runs. Until then, any address presented as one of these is not.

Buying with S: PairZap

A coin here trades against another coin, so someone holding only S has two trades to make. PairZap makes them as one transaction: an aggregator's route between S and the pair asset (LI.FI's router, fixed at deployment), then the coin's own Uniswap V3 pool. You sign a single minimum that bounds both; if either leg falls short the whole transaction reverts and you keep what you had.

It has no owner and no settings, holds nothing between trades, and keeps no allowance standing. Its swap callback pays only the pool of a swap it started, only while that swap is in flight. It is a convenience, not a gate: the pool is an ordinary Uniswap V3 pool, and anything that can trade one can trade your coin without it. It has not been audited.

The protocol coin

There is no protocol coin yet. When there is, it will be launched through PairLaunchpad like any other coin — same fixed supply, same locked liquidity, same contract code — and its address will be published here first.

Your coin's own contract

Every coin launched here is a PairToken, and every one of them will show 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. Once one instance is 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.

External contracts it uses

Every one of these was read off Sonic before it was written down (22 September 2026) — the factories through their own interface, the tokens by symbol, name and decimals, the feeds by description, and Uniswap's periphery by asking each contract for its factory().

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 — $5,000 if listed, $10,000 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:

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, paying the pool in its mint callback. 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.

The deploy scripts make the owner 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.
