How it works
01 · CreateOne transaction.Name, ticker, image and description go on-chain with the token. Your optional opening buy sits in the same transaction (launchAndBuy), so nothing trades before it. The fee recipient is always you.
02 · ClimbA curve in the pair its creator picks.Each coin is priced in the pair picked at launch: USDG, WETH, ETH or a tokenized share (TSLA, NVDA or AAPL) on Robinhood Chain. The whole supply sits on a constant-product curve whose phantom quote reserve is its opening market cap: $5,000 on a dollar pair and 2 ETH on an ETH pair. Every pair's figures are under Parameters. The trade card prices every fill against the curve itself, immediately before you sign.
03 · GraduateIts pair's threshold raised → v4 pool.When the curve has raised its pair's threshold, $8,000 on a dollar pair and 3.2 ETH on an ETH pair, the crossing trade graduates the coin (at a $33,800 FDV on a dollar pair). The quote asset and about 23.7% of supply seed a full-range Uniswap v4 position in a locker with no withdraw. The remaining 14.8% is locked with it.
04 · EarnCreators keep their share of every fee.1% on every trade, before and after graduation, paid in the coin's own pair. Creators claim theirs at any time. A coin keeps the terms its curve copied at launch, and its own page states them.
Curve mathFor a buy of q after fees: tokensOut = q × tokenReserve / (quoteReserve + q). quoteReserve starts at the pair's phantom. Sells run in reverse. A partial fill at the threshold refunds the rest.
Chain by chain
Arc
| The money | Curves, market caps and every fee are priced in USDC, issued by Circle. On Arc the dollar is also the gas, so one balance pays for the coin and the transaction. |
| Graduation | $8,000 raised on the curve, then a locked Uniswap v4 pool. |
| The contracts | Our own contracts, deployed once: no proxy and no upgrade path, and the terms a coin launches with are copied into its own curve and cannot be retuned afterwards. One power outlives a launch and we name it rather than deny it: the protocol owner can redirect a coin's creator-fee stream, and only by proposing it on chain and waiting three days first. |
| The fee split | Fixed when a coin launches and read from that coin's own snapshot, never from a figure written here. It is a parameter per chain, so each coin page states its own. |
Robinhood Chain
| The money | Curves, market caps and every fee are priced in USDG, issued by Paxos, or in the pair the creator picked at launch: a tokenized share (TSLA, NVDA or AAPL), WETH or ETH. Gas is paid in ETH, so a wallet on Robinhood Chain needs both. |

Get USDC on Arc
Curves on Arc are priced in USDC, issued by Circle. On Arc it is the gas as well, so one balance pays for the coin and the transaction. A wallet needs USDC on Arc itself before it can launch or trade. The same ticker on another network is another chain’s token.
01 · BridgeFrom a chain you already hold USDC onUSDC moves to Arc with Circle's CCTP v2: it is burned on the source chain and minted on Arc to the same address, about a minute on the fast route. Nothing wraps it, so what arrives is native USDC.
02 · ExchangeWithdraw straight to ArcSend USDC on the Arc network to your own address. Check the exchange lists Arc withdrawals before you send: a token sent on another network arrives on that network, not this one.
Get USDG on Robinhood Chain
Curves on Robinhood Chain are priced in USDG, issued by Paxos, or in the pair a creator picks at launch: a tokenized share (TSLA, NVDA or AAPL), WETH or ETH. Gas there is paid in ETH, so a wallet needs both. It is a different token from USDC on Arc, with a different issuer and a different contract, and neither one reaches the other by sitting still.
01 · BridgeBridge in, and it arrives as USDGUSDG is Robinhood Chain's dollar. Bridge USDC in and the chain's own relayer converts it on the way, per Robinhood Chain's documentation. Follow that, not a path of ours: we have not run it.
02 · ExchangeWithdraw straight to Robinhood ChainSend USDG on the Robinhood Chain network to your own address. Check the exchange lists Robinhood Chain withdrawals before you send: a token sent on another network arrives on that network, not this one.
Get ETH on Robinhood Chain
ETH pays the gas on Robinhood Chain and is the pair of its ETH coins, $PARA among them. A wallet needs it on Robinhood Chain itself; ETH on another network is not there.
01 · BridgeFrom Ethereum or another chainRobinhood Chain is an Arbitrum chain, so the canonical Arbitrum bridge brings ETH in from Ethereum in about ten minutes, and takes about seven days to send it back. Across and the other bridges Robinhood Chain's guide lists bring it from more chains, faster. Follow their instructions, not a path of ours: we have not run them.
02 · ExchangeWithdraw straight to Robinhood ChainSend ETH on the Robinhood Chain network to your own address. Check the exchange lists Robinhood Chain withdrawals before you send: a token sent on another network arrives on that network, not this one.
Swap
swap.parabolic.family swaps every Parabolic coin for the money it launched in, and the money and majors of Arc, Robinhood Chain, Base, Ethereum and BNB Chain against each other, each on its own chain. Every quote is read live from the pool immediately before you sign, the slippage you set is the floor the wallet signs, and a quote that fails stops the trade.
| Climbing coin | Its own bonding curve, the bytes the coin page's trade panel signs. |
| Graduated coin | Its own Uniswap v4 pool, through our hook. |
| Money and majors | The money and the major assets of Arc, Robinhood Chain, Base, Ethereum and BNB Chain, each chain's against each other through that chain's own Uniswap v4 router, for the pool's fee and gas and nothing to Parabolic. Each asset is at the address its issuer or the chain's documentation names, every decimal read on chain (lib/swap-assets.ts). |
| Routing | A graduated coin trades on its own pool, at the one tier the hook registered. Every other listed pair goes through the Universal Router, quoted across Uniswap's four standard tiers with the best answer taken; a pair no tier can price signs nothing. A climbing coin signs its own curve and no router of Uniswap's. |
| Approvals | An ERC-20 going into a pool is pulled through Permit2, so a first swap of that token asks for an approval. On a curve the quote asset is approved to the router for a buy and the coin to the curve for a sell. The choice is remembered per chain, token and spender. The chain's own gas asset rides as value and needs none. |
| Liquidity | Third-party liquidity on a public pool. Nothing here guarantees a fill, and a routed trade can revert. |
| Large moves | A price impact past the house threshold arms the button and asks a second time, naming the figure. |
Create with AI, and My coins
Create with AI fills the create form from one sentence. A launched coin’s tools are under My coins.
| What produces it | A model through OpenRouter: Anthropic's Claude Haiku for the words, OpenAI's GPT Image model for the picture, drawn as a colourful 3D character portrait. Your sentence and any reference image you upload go to them. No wallet, no session and no identifier goes with either. |
| Your responsibility | What comes back is generated. You choose what to launch, including any rights in a character, a mark or a likeness. |
| Immutable | Name, ticker, description and image are constructor arguments on the token with no setter. Nothing can change them after the launch. |
| Signing in | A wallet signature. A wallet is the only one that can launch, because the launching address is the address a coin has for ever. Projects are kept per account. |
| What is stored | The session is one identifier in an HttpOnly cookie, signed with HMAC-SHA256, SameSite=Lax, 30 days rolling. Google is asked for openid alone; X for the public handle and id. |
| Coin website | A coin whose ticker can be a hostname gets <ticker>.parabolic.family, public to everyone and editable by its creator: about, links, gallery and a pinned post. A ticker that is a name this site already answers on, that reads as an internationalised name, or that runs past 63 characters gets none. The hostname belongs to the oldest coin carrying the ticker, and a denylisted coin holds none. |
| Website on chain | The URL is written into the token's socials at launch, and only after a fresh check says the host is free. A failed check writes nothing. |
| Visits | One count per UTC day and a count per referring host, for the creator. No IP, no user agent, no identifier. |
| Post kit | The brand kit renders a coin's launch, card, milestone, graduation and recap posts from its real picture and its real figures, one file at a time or as a zip. |
On the site
| Promotion | Six paid spots: four on the board and two in Hypermode, bought by sending the stated amount to the treasury from your own wallet with the booking in the calldata, read back from the receipt. Every placement is labelled. No refunds. |
| Referrals | 10% of the whole trade fee, which is 0.10% of a referred curve buy. The code rides the routed action, the indexer credits it in its own ledger, and Parabolic pays it by hand from the protocol's share. No contract pays it, and a pool swap carries none, so referrals end at graduation. |
| Confirmation | A coin's own X account posts a code derived from the token address. The site reads the post through X's public oEmbed endpoint and takes the author from X's answer, never from the pasted link. It proves the account said the coin is theirs, and nothing more. |
| Alerts | Browser push with VAPID, or Telegram through the bot. A push subscription stores the endpoint, its public key and its authentication secret, with the coins and kinds chosen and a wallet address if one is given. A Telegram subscription stores the chat id, the coins and the kinds, on the bot's own disk. |
| Comments and lists | Comments, reactions, watchlists and follows are signed by your wallet and stored as site records. Comments, reactions and graduation calls are public on the coin they are made on; a watchlist and a follow list are readable by address. On-chain forum posts ride the router and are permanent. |
| Reservations (before mainnet) | A ticker, a coin name and an email, stored before launch. It reserved nothing on the chain, and the form closed with mainnet. |
| Moderation | A denylist per chain hides a coin from Explore, the API, the swap and its own subdomain, and its page says it is hidden and why. A coin Parabolic is discontinuing is also closed to buying here, and its holders can still sell it from its page. The reasons are published in the repository as docs/moderation.md. Nothing on the chain changes. |
Plans
Prices and checkout are on /plans.
| Plans | Free, Pro $25 and Ultra $200 a month, paid in USDC on Arc, or USDG or USDC on Robinhood Chain; a year for 10 months' price. Paid from the wallet to the treasury; the plan starts when the payment is read back from the chain. Nothing renews; a reminder goes out three days before the end. |
| Modes | Normal and Safe mode are free for everyone, always. Hypermode (Pulse, the terminal, multi-chart and one-press trading) is part of Pro and Ultra from the day plans go on sale, and open to everyone until then. Killermode is part of Ultra: its launch sniper and bots, live blocks (every trade of a coin made on Parabolic, pons or another launchpad the feed decodes, on Robinhood Chain, about a second after it lands), live holders and creators and speed pack (alerts in the page within a second, up to 10 wallets a press) are each listed as coming until they are built, and a plan bought today includes them only once they exist. |
| Killermode | Killermode is a trading room that is part of Ultra. Its four groups (live blocks, live holders and creators, the speed pack, and the launch sniper and bots) each open only once they are built, and are marked coming until then. Every figure is public chain data, read and linked. Nothing here is private information. Every trade of a coin made on Parabolic, pons or another launchpad the feed decodes, on Robinhood Chain, about a second after it lands. Nothing is visible before a block on either chain, to you or to anyone else. Killermode places no trade around somebody else's: no sandwiching, and no front-running of an identified user trade. |
| Intelligence coverage | Reports and bubble replay cover supported EVM coins; Solana intelligence is unavailable. |
| What a plan raises | Launch watchers 1 / 10 / unlimited, alerts 5 / 50 / unlimited, tracked wallets 5 / 100 / 500. Pro adds supported EVM intelligence reports and bubble replay; Ultra adds supported EVM report exports and webhooks. |
| Automated orders · coming | Supported EVM accounts on Pro and Ultra. Pro grants a key up to $250 a trade and $1,000 a day, in USDC or USDG; Ultra is held only by the session module's own limits. Every order still fills in the order its trigger is met. |
| API keys | Made on /plans with one wallet signature and shown once; only their hash is kept. Send one as x-api-key (or Authorization: Bearer) and the public API holds you to your plan: 60 / 600 / 3,000 requests a minute. Without a key the API answers as it always has. |
| Webhooks | Ultra. Every alert your watchers fire is POSTed as JSON to one https URL you set, signed as x-parabolic-signature: t=<seconds>,v1=<hex HMAC-SHA256 of "<t>.<body>" with your secret>. Delivered while the plan is Ultra, alongside the push and Telegram deliveries, and not retried. |
| Speed | Data and alerts, not trades. Alerts go out within 15 s on Free, 5 s on Pro and 1 s on Ultra, Ultra's first in each pass; signals and intelligence refresh every 5 min, 1 min and 15 s. A trade goes through the same public contracts and mempool for everyone, and nothing reorders anybody's transaction. |
| What a plan never does | Rank a coin as a buy, promise a return, or lock a safety fact. Concentration, creator sells, bundles and cluster shares are free. |
| Prizes | The top 3 of each weekly league get a Pro month, recorded on the plan like a payment, marked as a grant. |
| A signed sale · coming | A take profit, a stop or a limit sell is typed as a market cap and signed as what your tokens would bring there on that coin, impact and fees included. The floor under a stop is 5%, 10% or 25% under that, by your choice. Before you sign, the page says what the sale brings at the level and today, the least the executor key may sell it for, and the most it can cost you against today's price if that key were stolen. |
| A stop you raise · coming | A trailing stop's trigger follows the best price; its signed floor does not. When the trail has run 10% above the trigger you signed, Orders offers Raise: one signature for the new stop, then one transaction that cancels the old one on chain, because an order only taken off the executor's list is still valid on chain. |
| Open-coin rules · coming | A copy or a snipe names no coin, so it signs a scope: which launchpads, the most creator tax, how old the coin may be, the most its deployer may hold, and for a copy the leader. The module checks the scope on the coin the executor picks, and your grant's open-coin day caps what all such rules spend, up to twice this in any 24 hours, because the day resets at midnight UTC. |
| The executor · coming | A fill we never send has no on-chain remedy. If the executor is silent, the page says so within two minutes; your own cancel, your own revoke and a sale by hand are the remedy. While the coin graduates (a few seconds) no stop can fill; the executor finishes the graduation if the keeper has not. |
| Ending it · coming | Parabolic never holds your coins or your keys. The executor's key can only fill orders you signed, inside the limits you signed, into your own wallet. You end it with the emergency stop: one transaction revokes the grant and every order, and a second zeroes the allowance the module had. |
| Review · coming | The session module is Parabolic's own contract. It has been reviewed by Parabolic and has not been audited by anyone outside it. |
Other launchpads
Their coins are on Explore, where the launchpad pill chooses one.
| What it is | Supported EVM coins, bought and sold through Parabolic's aggregator router, which calls that launchpad's own curve or pool on your behalf and sends the result back to your wallet in the same transaction. |
| Fee | On EVM aggregator routes, the launchpad's own fee, plus the router's on every routed buy and sell, paid by the trading wallet to Parabolic's treasury in the same transaction: 0.6% on Free, 0.3% on Pro, 0.1% on Ultra. A plan's lower fee is a signed voucher the router checks. The router's ceiling is 1% in its bytecode. Applies to enabled Parabolic aggregator and Solana provider routes. Direct Robinhood Chain and Base swaps add no Parabolic fee. Venue fees and network costs are extra; the trade preview shows the route's charges. Solana discounts require a verified link to the wallet holding the plan. |
| Whose contracts | That launchpad's. We did not write them and cannot change, pause or upgrade them. Their snipe tax, their graduation and their fees apply as they wrote them, and the router reads the snipe tax before a buy and refuses one above your limit. |
| Switching one off | Each launchpad is enabled in the router one by one, and can be switched off by the owner or the guardian at any time. That stops trading it through this site and changes nothing on its own chain. |
| Launching there | Create and the Studio can launch a coin on another launchpad: your wallet signs that launchpad's own launch, so the coin lives on their contracts and its fees wait in their escrow, claimable from the Studio's Earnings. Parabolic charges nothing to launch; the opening buy is a second transaction through the router at its fee (0.6% on Free). Offered only where the router is deployed and that launchpad is switched on in it. |
How safe mode decides
| Off until you turn it on | Safe mode is opt-in, on this device only. Choose Safe in the mode switch at the top of any page, or turn it on from Hypermode's settings or any coin page. |
| Warns, never hides | A flagged coin stays where it was on every list, in the same order, with a red badge. Tap it for the reasons and the evidence. A paid placement keeps its Promoted label and the badge. |
| Asks, never caps | A buy of a flagged coin asks you to confirm, listing the reasons. The amount, the slippage and the route do not change, and a sell is never asked about. |
| Unread is not a pass | A check that could not be read marks the coin "not fully checked", which asks too. |
| Check | Flags when | How serious |
|---|---|---|
| Creator moved coin to new wallets · Rug radar | 1% of supply or more sent to a wallet that never held or traded the coin. Coin burned, sent to Parabolic's contracts, to a holder claim or to a known token lock is said, not flagged; coin leaving that lock for another wallet counts | severe if that wallet has sent 3 transactions or fewer, warning otherwise |
| Creator sold a large part of their holding · Rug radar | more than 25% of what they held, within 60 minutes | severe at 1% of supply or more, warning under |
| Linked wallets sold together · Rug radar | two or more wallets of one cluster selling 1% of supply or more within 10 minutes | severe at 3% or when the cluster is tied to the creator |
| A large holder exited · Rug radar | a top-10 wallet selling 50% of its position or more within 15 minutes | severe when the position was 5% of supply or more |
| Older events · Rug radar | a radar event more than 24 hours old stays listed | one step lower |
| Creator holds a large share · Thresholds | more than 10% of supply, with a lock of theirs counted once it unlocks | warning |
| Supply is concentrated · Thresholds | the 10 largest wallets hold more than 40%, with the curve, the pool, protocol contracts and holder claims left out | warning |
| Volume is self-funded · Thresholds | more than 20% of volume from wallets funded from one source or by the creator | warning |
| Coin is minutes old · Thresholds | launched less than 10 minutes ago | warning, clears by itself |
| Inside the snipe window · Thresholds | the first 5 seconds after launch, while the launch tax is above zero | severe, clears by itself |
| Thin liquidity · Thresholds | a $100 sale moves the price 5% or more | warning |
| Ticker already used · Copies | another coin launched earlier with the same ticker | severe if that coin graduated, warning otherwise, a note when it is the same creator's |
| Looks like a known coin · Copies | one character or look-alike off a known coin, judged from 4 letters, or a real asset's ticker | severe for a money's ticker, warning otherwise |
| Picture used by another coin · Copies | the same picture address as an earlier coin, or within 6 of 64 bits of its fingerprint | severe for the same address, warning for a look-alike |
| Social account belongs to another coin · Copies | the X account in the coin's links confirmed a different coin | severe |
| Hidden by Parabolic · Copies | the coin is on Parabolic's denylist | severe |
| Creator's record · Creator | a Poor record, under 40 of 100 (Good from 70) | warning; a new creator is a note, never a warning |
Every line is fixed by Parabolic and the same for every reader: there is no setting to move one. Each coin's full reading, with its evidence and every check marked clear, flagged or unread, is public at /api/v1/risk/coin/<ref>. A reading of data, not advice.
Season

Parabolic token
$PARA is Parabolic's own coin. It launched on Parabolic on Robinhood Chain on 15 October 2026 the way every coin does, paired with ETH: its whole supply minted to its curve, with no presale, no private sale, no allocation and no airdrop, so every PARA anyone holds was bought on that curve, its creator's included. 10% of the supply, held by its creator, is locked in RobinhoodLocker until 30 October 2027. The coin is 0x24B6B4b111AB1cb06F0F4215c5f6cdd2719FcD16 on Robinhood Chain; anyone offering another Parabolic token, a presale or an allocation is not us; report it to contact@parabolic.family. Holders of the old PARA on Arc can claim the new token one for one at parabolic.family/claim, from tokens bought on its curve like anyone else's.Parameters
| Term | Value | Notes |
|---|---|---|
| Supply | 1,000,000,000 | Fixed, 18 decimals, no mint function. |
| Opening market cap | the pair's reserve | The phantom quote reserve of the coin's pair: $5,000 on a dollar pair and 2 ETH on an ETH pair. Every pair is in the table below. |
| Graduation | the pair's threshold | What the curve has raised in the coin's pair: $8,000 on a dollar pair and 3.2 ETH on an ETH pair. The crossing buy graduates it. |
| Reserved at graduation | 38.5% of supply | About 23.7% seeds the v4 position at the graduation price, about 14.8% is locked with it. |
| Launch fee | read at launch | Charged by the factory as the transaction's value, so it is paid in whatever this chain charges gas in: USDC on Arc, which is itself a dollar. The create page reads it before you sign. |
| Trade fee | 1% | On every curve and pool trade. The split is fixed at each coin's launch and shown on its page. |
| Buybacks | by the treasury | Nothing of the fee is locked or vested under the policy since 17 Sep 2026. The protocol's share goes to the treasury, which buys back by hand. Coins launched before that carry a vault share; each coin page shows its own terms. |
| Creator tax | 0 to 5% | Optional, chosen at launch, paid to the creator on top of the trade fee. |
| Snipe tax | 93% → 0 over 5 s | On buys inside the opening window. Only the creator's own address is exempt, for any buy inside it. |
| Referral | 10% of the fee | 0.10% of every referred curve buy, credited by Parabolic in the indexer's ledger and paid by hand from its own share of the fee. Not paid by the contracts. A pool swap carries no memo, so referrals end at graduation. |
| Liquidity | locked forever | The v4 position sits in a locker with no withdraw function. |

Memo format · v1Posts and referral codes ride on Arc transaction memos through the router. Referrers are credited 10% of the whole fee, 0.10% of each referred buy. No contract sees the code: the indexer credits it in its own ledger and Parabolic pays it by hand from the protocol's share of the fee. Version 1 is what the router reads; a later version would be announced here first.
Memo.memo(router, calldata, memoId, payload) // Arc Memo 0x5294…e505, EOA only, forwards no value
payload = abi.encode(uint8 version = 1, uint8 action, bytes8 referral, string note)

Routes the site calls for itself (Killermode, the Studio, social, the executor's own) are same-origin and not part of this API. Reads need no key. A Parabolic API key (made on /plans or /developers with a signature from any wallet) is optional: sent as the x-api-key header or as Authorization: Bearer pk_…, it holds the request to its plan's rate instead of the per-address one, in requests a minute: Free 60, Pro 600, Ultra 3,000. A key that is not a Parabolic key, or one that was revoked, is a 401; past the plan's rate is a 429 with retry-after. Data API plans (on /developers, where the Data API is open) raise the rate, add a daily quota metered per key (GET /api/v1/data/usage) and the authenticated firehose (GET /api/v1/data/stream). Schema: openapi.json. Responses are cached 3 s at the edge and served stale for up to 10 s while revalidating (the header sent is cache-control: public, max-age=0, s-maxage=3, stale-while-revalidate=10; the edge consumes s-maxage and stale-while-revalidate, so a client sees public, max-age=0 and an x-vercel-cache header). GET /api/v1/coins is held 5 s and served stale for up to 30 s (cache-control: public, max-age=0, s-maxage=5, stale-while-revalidate=30); an error is never cached at all.

Every tool is named parabolic. plus the name below.list_coins, get_coin, protocol_stats, docs read the protocol.quote_buy and quote_sell price a trade on live reserves.check_ticker asks whether a coin already carries a symbol on any chain this site serves, and whether that ticker's subdomain is free. Advice, not a gate.agent_status and build_register_agent_tx read and register an ERC-8004 identity, on a chain that publishes a registry.build_launch_tx, build_buy_tx, build_sell_tx return { to, data, value, chainId } for your own wallet to sign.referral_status reads one wallet's referral payouts: credited, published, paid and claimable, per asset.svm_portfolio reads exact Solana balances and measured PnL where cost history is complete; svm_activity reads the reader's bounded Solana trade history, preserving wallet and mint case. Missing history and mixed quote assets stay explicit.build_svm_swap_tx prepares an unsigned Solana swap with checked minimum output and fees where trading is open; it never signs or sends. list_venue_coins lists coins made on another launchpad; quote_routed_buy, quote_routed_sell, build_routed_buy_tx and build_routed_sell_tx price and build a trade in them through Parabolic's aggregator router, with both fees shown; venue_history reads one such coin's candles, fills, holders and escrow balance, or a wallet's positions, as the site reads them from the chain.It never holds keys, never signs and never broadcasts.
