Constants

Constant	Value
`TOTAL_SUPPLY`	1,000,000,000 × 10¹⁸ (18 decimals)
`COIN_SLACK`	10¹² wei of the supply kept out of the position to absorb rounding (one millionth of a coin)
`LP_FEE`	0: the pool charges no fee of its own
`TICK_SPACING`	10
`MIN_FEE_BPS` / `MAX_FEE_BPS`	10 (0.10%) / 300 (3%); the form offers 10 to 300 in steps of 10
`MAX_SNIPE_BPS`	3,000 (30% on buys, decaying)
anti-snipe window	5 to 7,200 blocks (`MAX_SNIPE_BLOCKS`); about two hours of HyperEVM small blocks
`MAX_POT_EACH_BPS`	5,000: holder rewards at most 50% of the fee, buyback at most 50% of the fee
`MAX_POT_SHARE_BPS`	8,000: holder rewards and buyback together at most 80%
`buybackThreshold`	at least 1,000 pair base units when a buyback share is set
`BUYBACK_SQRT_BPS`	10,149: a burn stops once it has moved the price about 3% up
`maxWalletBps` / `maxWalletSecs`	50 to 2,000 (0.5% to 20% of the supply) / 600 to 2,592,000 seconds (10 minutes to 30 days)
`CREATOR_SPLIT_BPS`	6,000: 60% creator / 40% platform of what remains
`MAX_REWARD_EACH_BPS`	5,000: cashback and referral each at most 50% of the platform's part
`MEV_FREE_PRIORITY` / `MEV_PRIORITY_UNIT` / `MEV_CAP_BPS`	1 gwei / 0.05 gwei / 2,000: the priority-fee surcharge
cap presets	$3,000, $10,000 and $25,000, fixed at deployment; a launch picks one by index (`capPreset`)
`TAKEOVER_IDLE` / `TAKEOVER_DELAY` / `TAKEOVER_STAKE`	30 days / 7 days / 5% of the supply
rewards push threshold	100,000 coins (0.01% of the supply) held by claimable wallets (`minShares`)
router hops	at most 4 per route (`MAX_HOPS`)
CREATE2 salt search	up to 512 tries to find a coin address below the pair's (`NoSalt` otherwise)
launch gas	about 1.2M: inside a HyperEVM small block (3M gas, about one a second)

Error	Contract	Reason
`InvalidParams`	factory	empty name or symbol, an unknown preset, a takeover stake below 5% of the supply, or an internal check such as the coin address not being below the pair's
`BadGenes`	factory, hook	fee outside 10 to 300 bps; anti-snipe start not above the fee or above 3,000; window outside 5 to 7,200; rewards or buyback share above 5,000, or together above 8,000; a buyback threshold below 1,000; max wallet outside 50 to 2,000 bps or 600 seconds to 30 days; or one half of a paired setting set without the other
`NotCreator`	factory	a creator function called by someone else, or `acceptCreator` by an address that was not offered the role
`TakeoverClosed`	factory	the creator is not idle yet, the stake does not beat the running proposal, the 7-day delay has not passed, or the creator acted since the proposal
`LaunchBlockClosed`	hook	a buy other than the dev buy in the launch block
`BuyCapExceeded`	hook	a buy that would take one wallet over its max-wallet cap while the window runs
`NotThisPool`	hook	the token is not a Liqio coin
`NothingToPush`	hook	the rewards or buyback pot is empty
`NoHolders`	hook	fewer than 100,000 coins are held by claimable wallets
`NotListed`	router	the coin is not a Liqio coin
`Slippage`	router	the minimum output was not met
`ZeroAmount`	router	a zero input
`BadRoute`	router	a route that is empty for a stock or USDC pair, has more than four hops, or does not run from WHYPE to the pair
`QuoteResult(amount)`	router	not an error: the result of `quoteEthToPair`
`NoSalt`	token deployer	no address below the pair's found in 512 tries
`NoPeers`	token deployer	a non-empty `peers` argument; a Liqio coin lives on HyperEVM only
`NoShares`	coin	a rewards push while fewer than 100,000 coins are held by claimable wallets
`NotHook`	coin	`distribute` called by anyone but the hook
`WrongInit`	coin	`initialize` called on a rewards coin, which uses `initializeDiv`
`NoPrice`	oracle	the pair token has no source, or its HyperCore market returned no price

Known limits

The hook supports dynamic and MEV-tax fee modes and staged parameter changes; Liqio launches use the flat fee and send those settings as zero.
The fee quoted by feeBpsNow and shown on the site assumes a priority fee of at most 1 gwei. A transaction with a larger tip pays the priority-fee surcharge on top.
A stock-paired coin's USD price depends on the wrapped xStock's HyperCore oracle price, which follows NYSE hours while the pool trades at any hour, and on the wrapper's share ratio, which the oracle reads live from the token (so the price is a little above the stock's and rises slowly).
Trading a stock-paired coin in HYPE passes through the stock's pool against WHYPE; its depth bounds how much can be traded at once without large slippage. A stock with no route (wMUx, wSKHYx, wQQQx) has no HYPE trading and no dev buy.
A launch reads the oracle once; a pair that is not in the oracle's list, fixed at deployment, cannot be launched against (NoPrice). Adding a pair means a new Liqio version with its own factory and oracle; coins on an older version keep trading there.
The max-wallet ledger counts per tx.origin, so a smart wallet relayed through a shared bundler shares that bundler's allowance for the window.
Holder rewards are only recorded for the balances held when a push happens. Coins bought after a push earn from the next one.
The launch sends a minimum pair amount of 0 for the dev-buy conversion, so a stock- or USDC-pair dev buy accepts whatever the route returns in that block.
The contracts hold no listing flag. If the website ever filters what it shows, that is an off-chain choice of the website and changes nothing on chain: the coin page and the pool keep working.
