What the contracts do

what gatara is

A launchpad with a reader in the room.

Gatara is a token launchpad on Robinhood Chain. Every token here is born in one transaction: a fixed supply, a live Uniswap v4 pool priced in ETH, and the whole supply sealed inside that pool as its price curve. There is no bonding curve to climb and no graduation to wait for. The market is real from its first block, and no one, Gatara included, can take the liquidity back.

Around that market sits a reader. A machine-learning ensemble scores every launch on the chain from its first trades, and two characters put the score into words on the board: the Bookie reads the tape, the Lurker reads the rooms. A read is a rating, never a promise. Nothing the models say ever touches a trade.

Three things to do here: launch a token, watch the board and trade, and read this page.

the launch

One transaction. A real market. Liquidity that cannot leave.

One call to the launcher does all of this, or reverts:

• mints a fixed supply of 1,000,000,000 tokens from a shared factory. A plain ERC-20: no mint, no burn, no tax, no owner
• opens a Uniswap v4 pool against native ETH with the Gatara hook attached, the fee terms written into the pool at birth
• sets the opening price at tick 204200, which values the whole supply at 1.3557 ETH
• deposits the entire supply as single-sided liquidity from the opening price to the top of the range. Buyers pay ETH into the pool, and that ETH is the liquidity that lets sellers out
• keeps the liquidity position inside the launcher forever. The launcher has no function that moves it
• optionally makes the creator's first buy in the same transaction, up to 0.24 ETH (about 15 % of the supply), exempt from the cocoon and the fee, with a custody choice: liquid from block one, locked for a term and released all at once, or vesting linearly over the term (1 day to 10 years)

Launching costs gas and nothing else. No launch fee, no listing fee, no allowlist.

the cocoon

Sixty seconds. A price on sniping that falls to zero.

Every launch spends its first sixty seconds inside the cocoon.

• buys pay a surcharge on top of the token's fee. It opens at 60 % and falls along a parabola: 41.66 % at second 10, 15 % at second 30, 3.75 % at second 45, gone at second 60
• the launch second itself is closed to everyone but the creator. A third-party buy in that second reverts
• sells are never surcharged and never blocked. The way out is open from the first block
• the surcharge is paid to the house, never to the creator, so a creator gains nothing by sniping their own launch

The cocoon is not a promise that no one snipes. It is a price on sniping that falls to zero on a known clock: a bot that is early pays the most, and the crowd that arrives a minute later pays nothing extra.

the terms

One to five percent, in ETH, fixed at birth. The house keeps half a point.

The creator sets two fees at birth, one for buys and one for sells, each from 1 % to 5 % in whole steps. They are written into the pool and no one can change them afterwards.

Every fee is taken in ETH, on every swap, from the ETH side of the trade:

• the house keeps a flat 0.50 % of the trade, carved out of the creator's fee, never added on top
• the creator keeps the rest: 0.50 % to 4.50 % of every trade, by the terms they chose
• the fees accrue inside the hook from the first swap and are claimable at any moment. No milestone to reach, no lock on earnings

A worked trade: a $1,000 buy on a token with a 2 % buy fee pays a $20 fee. $5 goes to the house and $15 to the creator. The same buy at second 10 of the cocoon pays $436.60: $416.60 of surcharge to the house, then the $5 house share, then $15 to the creator.

Fees a creator never claims do not sit forever. After 365 days without a claim, anyone may sweep them to the house. Any claim, even an empty one, restarts that clock.

what cannot happen

No owner, no pause, no upgrade, no key.

The contracts are written so that the interesting sentences are the ones with "cannot" in them.

• the liquidity cannot be withdrawn. The launcher holds the position and has no function that moves it
• the fees cannot be changed. They are read from the pool's configuration set at launch
• the cocoon cannot be extended, re-armed or pointed at a different recipient
• there is no owner, no pause, no upgrade and no admin key on the launcher, the hook or the tokens. The only privileged addresses are fee recipients, fixed at deploy, and receiving is all they can do
• the models cannot touch a trade. Scoring lives off-chain and reads the chain. Nothing on chain reads the scores

The v1 contracts are not externally audited. Two reviews ran before launch: a structured internal audit of the full source, one broad reviewer plus independent adversarial verifiers whose job was to refute a clean result, and a Uniswap v4 hooks security review. The contracts went live on 2026-08-09 behind four release gates: frozen economics, a green fork suite against the chain's real PoolManager and router, those reviews, and a canary launch verified event by event. All three contracts are verified on the explorer. An external audit is commissioned the day fees held in the hook sustain above about 50 ETH. Read the trust record before you rely on any of it.

Known edges, stated plainly: a swap the pool cannot fill in full reverts rather than overcharging; buys in the launch second revert; an exact-output buy inside the cocoon can cost up to 2.7× its output; fees are per pool, not per token, so a rival pool without the hook pays the creator nothing.

the reads

A rating from 0 to 100. Never a promise.

Every token on the chain, not only Gatara's, is scored by a gradient-boosted ensemble trained on the chain's own trade history. The score is a rating from 0 to 100 of how the next half hour looks. It is not a probability and is never shown as one.

• the read: 0 to 100. Below 51 the house has no line. 51 to 69 is a soft call, 70 to 88 a firm call, 89 and up an alert
• the bet: up 30 % inside the half hour. A call lands if the bet does
• the record: every call is written down when it is made and graded when its window closes. The board shows the house's record, settled calls, how many landed, how many are open
• the Bookie narrates the tape on the board. The Lurker reads the rooms on X and files a dossier when a token holds an alert

None of it is advice and none of it is a promise. The record is the honest number, and it is on the board because a reader who cannot see the misses cannot trust the hits.

the house

Half a point on every trade, plus the surcharge. In ETH, on chain.

The house is what Gatara earns: on chain, in ETH, from two sources.

• 0.50 % of every trade on every Gatara token, inside the creator's fee
• the cocoon surcharge on early buys, in full

That is the whole revenue system. No launch fee, no subscription, no fee on anything that is not traded. Both accrue inside the hook and are claimable only by the treasury, a Safe at 0xC5C3…967d, and every ETH of it traces back to the swap that paid it.

the flywheel

The crank, the split, the burn.

The house's take does not stop at the treasury. When GATARA launches, the treasury claims its fees into three small, immutable contracts, and the whole loop is public:

• the crank. Anyone may call it. It moves the house's swap share to the splitter and the cocoon surcharge to the burner. It can do nothing else
• the split. Half of the swap share goes to the burner, half stays with the treasury to run the house: the models, the RPC, the Lurker's reads. The split is bytecode, not a setting
• the burn. The burner holds ETH and releases it on a seven-day linear drip. Anyone who burns 250,000 GATARA in the same transaction may take the released ETH, up to 0.5 ETH a claim. The burner never swaps and has no oracle: a searcher buys GATARA on its own pool, burns it, and keeps the difference. Competition between searchers pins the exchange to the market price. The cocoon surcharge burns in full

One honest line about enforcement. The split and the burn are immutable. The claim into them is not: the treasury's Safe can stop cranking, and fees would then simply accrue in the hook. That is the v1 trust model. The policy is published here, every crank, flush and burn is on the explorer, and a stopped crank is the loudest signal the house could send.

The loop, then: launches are free, so tokens are born here. Trades pay creators in ETH from the first swap, so creators bring their crowd. The same trades pay the house. The house burns GATARA and runs the reader. The reader is why you trade here rather than anywhere else. More trading, more launches, a bigger take, a bigger burn.

There is a second, quieter loop. Every fee here is paid in ETH, so washing volume costs real money, and the models learn from the tape. Volume that is expensive to fake is volume the reader can trust, which makes the reads better as the market grows.

the gatara token

Born on its own rails. Burned by its own volume.

GATARA is the house's token, and it is born on the house's own rails: the same launcher, the same cocoon, the same locked pool. Its terms are the house terms, 1 % on buys and 1 % on sells, the cheapest the launcher allows.

• supply: 1,000,000,000, fixed, all of it in the pool at birth
• the house's own bag: the creator's first buy of 0.24 ETH, about 15 % of the supply, vesting linearly over 365 days
• the creator's fees on the GATARA pool are claimed to the burner, never kept
• there is no allocation, no presale, no team unlock beyond the vesting bag, and no revenue share. What the token has is the burn: half the house's swap share and all of the cocoon surcharge buy GATARA off its own pool and burn it, for as long as the market trades

GATARA does not gate anything. The reads are free, the launcher is free, the board is free. Holding it is a position on the house's volume and nothing else.
