Flap.sh launchpad API on Robinhood Chain (contracts, tokens)

How Flap.sh launches tax and non-tax tokens on Robinhood Chain, graduates them to Uniswap v2 with burned LP, its contract addresses and the Crius API.

Flap.sh is a bonding-curve launchpad with a twist: tokens can carry a buy and sell tax from launch, routed to the creator, a vault or dividends for holders. Every Flap token’s curve lives inside one contract, the Flap Portal, which also emits every launch, trade and graduation. When a curve fills, the Portal moves the token into a Uniswap v2 pair and burns the LP tokens, so that liquidity can never be withdrawn.

Flap.sh at a glance

	Flap.sh
Crius launchpad id	`flap`
Launch	Through the Flap Portal (or the VaultPortal for tax tokens bound to a vault); no per-token curve contract
Token types	Tax tokens (address ends in `7777`) and non-tax tokens (address ends in `8888`)
Quote assets	Mostly native ETH; USDG and stock tokens (SPY, NVDA, TSLA and others) are enabled
Graduation	At 800 million tokens circulating (5 ETH raised on the default ETH curve)
After graduation	Uniswap v2 pair (a few on a Pancake-style fork) with 200 million tokens; LP tokens burned to `0x000000000000000000000000000000000000dEaD`
Fees	1% on curve buys and sells, plus the token's own tax for tax tokens
Graduation rate	0.087% (`graduation_rate_pct: 0.0872573`), median 8,533 blocks to graduate (about 14 minutes)

How a Flap token launches and graduates

Launch. A creator (or a smart account, or one of the batch “launch farm” contracts that mass-create tokens) calls the Portal, which deploys the token as a clone of the tax or non-tax template and sets its curve, quote asset and tax rates. Crius picks it up from the Portal’s TokenCreated event; the quote comes from TokenQuoteSet.
Bonding. Buys and sells go through the Portal (TokenBought, TokenSold). Each trade pays a 1% fee to Flap’s fee Safe; tax tokens also pay their tax on the curve. Fresh Flap tokens show status: "bonding" and often progress_pct: null in Crius lists until progress can be measured.
Graduation. The buy that takes circulating supply to 800 million triggers LaunchedToDEX: 200 million tokens and the raised quote (5 ETH on the default curve, added as WETH) go into a Uniswap v2 pair, and the LP tokens are sent to the dead address.
After graduation. The token trades on its v2 pair. A tax token keeps charging its tax on DEX trades, so check /security for the measured tax.buy_pct and tax.sell_pct.

Six vanity batch contracts mass-create Flap tokens, so a token’s creator can be one of them rather than a person: 0x8f96447d5d15571bc18705b2f1f09aec1b376666, 0x5bbb332a7ea0bbc98424304326c3dce71d8b6666, 0x8bf8eace53982a349195c452d1a22d025fae6666, 0xb3023412cf5fe15811a158234e3fd70a7d6b6666, 0x948ed9814055e4b74c3885f2de1599600b206666 and 0xcfc61f923c726a5f20dc56d8a925d31bf3e56666.

fees_usd_24h: $7,407.3 of measured taxes against $2,021.73 of LP fees. On Flap the tax tokens, not the pools, generate most of the fees.
history.points: 1,170, 1,241 and 1,078 launches on 2026-10-26, 27 and 28, with 0, 0 and 1 graduations.
top_tokens_24h: FabricAI (0xf62bd0bb50ef92ff591c8ff39252f40ad5097777, $168,253 of volume, 4,822 holders), Prism Assets (0x20024e485c0b22b42855589700721b28320a7777, 7,803 holders) and Vellum (0xeb4641bc510277848984ef9539d54ba05ebd7777), all graduated, all quoted in WETH and all ending in 7777: tax tokens.
contracts.launch_contracts lists the Portal; since_block: 4227932 is the first Flap launch.

What this tells you

Shortinu (0x294839975724eb79b21f96e900d5a66cf9077777) and United Dividend Trust Fund (0xbf2da78c89c4f51f108aa73d8d7a7ea8cd5e7777) are tax tokens (7777). Each has one buy of a fraction of a cent and market_cap_usd: 4083.1: the price at the bottom of the default ETH curve.
“we are all cooked” (0x60f5b9533d0382bcbb7112d078c9c38bff1a8888) is a non-tax token (8888) with no trades yet: price_usd: null, holders: 1.
All three have status: "bonding" and progress_pct: null.

Token lists reference Runs from your browser on the anonymous plan Data looks wrong? Report it

For one token, /token/{address}/launch (Free plan) returns the launchpad, factory, creator, quote token, launch transaction and block, status, graduated_block and the token’s pools. The measured buy and sell tax of a tax token is in the anonymous /security call.

Use it in your app

Filter the firehose. list=new&launchpad=flap&min_liquidity_usd=500 drops the hundreds of daily launches that never get a buyer.
Check the tax before you buy. A 7777 address means a tax token. /security returns the tax buyers actually paid (tax.source: "realized") and whether the owner can change it.
Expect slow graduations. The median Flap graduation took 8,533 blocks, and fewer than 1 in 1,000 tokens get there. list=graduated&launchpad=flap shows the ones that did.
Ignore the mirror pairs. If you also read chain data yourself, leave pairs from 0x0d1ebb179cdbca88d74c923c4255cb2b17474afd out of volume and liquidity; Crius already does.

Frequently asked questions

How do I track new Flap.sh tokens on Robinhood Chain?

Poll GET https://api.crius.sh/v1/robinhood/tokens?list=new&launchpad=flap, or subscribe to launches:flap on the WebSocket stream. About 1,200 Flap tokens launch a day, so add min_liquidity_usd to skip the ones nobody buys.

What is the Flap.sh contract address on Robinhood Chain?

Every Flap launch, trade and graduation goes through the Flap Portal, 0x26605f322f7ff986f381bb9a6e3f5dab0beaeb09. Tax tokens are clones of 0x7777c8743c88b3aff3cf262135bef2c8b2e83333 (addresses ending in 7777), non-tax tokens clones of 0x88882688a067fe97e11c2185b996286e53132222 (ending in 8888).

When does a Flap.sh token graduate?

When its curve sells through to 800 million tokens in circulation. On the default ETH curve that is 5 ETH raised; the Portal then adds 200 million tokens and the raised quote to a Uniswap v2 pair and burns the LP tokens. Only 338 of 387,360 Flap tokens had graduated when the samples were captured.

Why do Flap.sh tokens show up twice on some chart sites?

Flap creates a display-only Uniswap v2-style pair for each token on 0x0d1ebb179cdbca88d74c923c4255cb2b17474afd. Those pairs repeat every curve trade as a swap but move no tokens. Crius doesn't index them, so Flap volume and liquidity on Crius are counted once.
