Flap Trading Terminal and Bot
Looking for a flap trading bot and sniper? Flap is a launch protocol that grew up on BNB Chain, where it now does more curve volume than any other launchpad, and it has run on Robinhood Chain since July 2026. Its coins come in two kinds, plain and taxed, and a taxed coin can pay its holders dividends in tokenized shares like Nvidia and the S&P 500 ETF. Axiom reads Flap on both chains: in the BNB protocol filter, and as Flap and Flap Tax in the HOOD filter, right after Pons. Use Axiom referral code TradeNow for 20% off trading fees.

Flap on Axiom
What is Flap, and how does it look from Axiom?
Flap, at flap.sh, is an on-chain token launch protocol for EVM chains, backed by YZi Labs. It began on BNB Chain in 2024 and also runs on Robinhood Chain, X Layer, Monad and Base. Every Flap coin has a supply of one billion, 80% of which is sold along a bonding curve; when that 80% is gone, the rest of the supply and the whole reserve move into a DEX pool, PancakeSwap on BNB Chain and Uniswap V2 on Robinhood Chain. A creator chooses between a plain coin and a Flap Tax coin, whose tax can be paid out to holders in stock tokens.
The two chains are very different markets. On BNB Chain Flap leads: DefiLlama counted $734 million of volume on its curves there in August 2026, seven times Four.meme's. On Robinhood Chain it is a much smaller venue than Pons, and Axiom splits it into two entries, Flap and Flap Tax, third and fourth in the HOOD filter behind Pons and Pons V2.
| Chains | BNB Chain since 2024 and Robinhood Chain since 9 July 2026; also X Layer, Monad and Base |
|---|---|
| In Axiom's filter | Flap on BNB; Flap and Flap Tax, third and fourth, on HOOD |
| Coin types | Plain coins, launched with addresses ending in 8888, and tax coins, ending in 7777 |
| Curve | One billion supply, 80% sold on a constant-product curve |
| Graduation on BNB | About 16 BNB raised, into PancakeSwap: V3 for plain coins, V2 for tax coins |
| Graduation on HOOD | About 5 ETH raised, into a Uniswap V2 pool, for both types |
| Pairs on BNB | BNB, stablecoins, coins such as BTCB and SOL, XAUt gold and around twenty bStocks |
| Pairs on HOOD | ETH, USDG and Robinhood stock tokens such as NVDA, SPY and SPCX |
| Flap fee | 1% per trade on the curve only, on both chains; nothing after graduation |
| Flap Tax coins | Creator-set buy and sell taxes, plus up to 0.3% for Flap's tax processing |
| Size | About $639 million of curve volume on BNB Chain and $7.9 million on Robinhood Chain in 30 days (DefiLlama) |
| Axiom fee | 1% per trade on either chain, 0.8% with code TradeNow |
Axiom or flap.sh?
flap.sh launches coins on several chains and runs the tax machinery behind Flap Tax coins. Trading them on BNB Chain and Robinhood Chain from one place is what Axiom adds.
Beside Four.meme
On BNB Chain, Pulse shows Flap launches next to Four.meme's, the other big curve there, so the choice between them is made on one screen.
Kept off the public path
BNB orders from Axiom go through private RPCs, which counts once a coin reaches PancakeSwap and the sandwich bots with it.
Graduation orders
At about 16 BNB, or 5 ETH on Robinhood Chain, a curve moves into its DEX pool, and Axiom's migration orders act at that moment.
Flap takes 1% per trade on the curve and nothing after graduation, while Flap Tax coins add their own taxes; Axiom's 1%, or 0.8% with TradeNow, applies on top. Launching and tax settings stay on flap.sh.
Flap on BNB Chain
BNB Chain is Flap's home market, and the one where a Flap coin is most likely to finish its curve.
The BNB curve
On the current BNB curve a coin graduates once 800 million tokens have sold, by which point about 16 BNB has been raised, roughly $12,600 at today's price, and the coin is valued near 72 BNB fully diluted. A coin priced in something other than BNB gets its own target in that asset, such as 45 NVDAb or 2,000 BNCb.
Where BNB coins graduate
A plain coin moves to PancakeSwap V3, its liquidity spread from the curve's opening price up to 10,000 times the final one, and drops back to V2 only if V3 cannot take it. A tax coin always goes to a PancakeSwap V2 pair.
Pairs on BNB
About two in three new coins are priced in BNB. The rest spread wide: the Portal accepts dollar stablecoins such as USD1, USDT and USDC, large coins such as BTCB, SOL and DOGE, XAUt gold, ASTER and around twenty bStocks from NVDAb and TSLAb to BNCb, and one day's launches used 99 different pair assets between them. Binance Wallet's September trading competition counted Stock Memes from Flap and Four.meme alike.
A day on the BNB Portal
In the 24 hours to 23 September the BNB Portal recorded 18,039 launches and 97 graduations, about one coin in 190. Sixty-four wallets with 50 or more launches each made nearly two thirds of them, and all but 77 were tax coins; the most common setting, on 38% of launches, was 8.99% each way.
How a Flap Coin Moves on Robinhood Chain
The curve
All one billion tokens start inside Flap's bonding curve, a constant-product formula with virtual reserves. Buyers pay into the curve, sellers take their quote asset back out, and the price follows the share of supply already sold. The curve stops selling at 80%.
No pools before graduation
While a coin is on its curve, transfers into or out of any trading pool are blocked; only wallet-to-wallet moves work. Nobody can seed a DEX pool early and trade around the curve, so the curve is the only market until graduation.
Graduation to Uniswap V2
When 80% of the supply has sold, at about 5 ETH raised on an ETH pair, the remaining fifth and the curve's whole reserve seed a Uniswap V2 pool. Both coin types graduate there; Flap's other migration routes are switched off on this chain.
The anti-farmer window
For a while after a plain coin graduates, only its main pool can take the token; transfers into any other pool fail outright. Flap's own example sets that window to one day, after which the coin trades freely anywhere.
Flap Tax: Coins That Tax Every Trade
Flap Tax is Axiom's name for the taxed version of a Flap coin, and the tax is the first thing to check before buying one.
New tax coins on both chains are Flap's Tax Token V3. The creator sets a buy tax and a sell tax, and they do not have to match: a low buy tax to draw people in and a much higher sell tax on the way out is an allowed setup. The token reports the higher of the two as its headline rate, so the number you see is the worst case. While the coin is on its curve the tax is simply added to Flap's 1% fee and taken in the quote asset, so a 3% coin costs 4% a trade. Flap's tax processing adds up to another 0.3% of volume.
After graduation the mechanics change in a way traders notice. The tax is taken in the coin itself and piles up inside the token contract, and once the pile passes a threshold it is sold into the pool for the pair asset automatically. A taxed Flap coin therefore sells a slice of itself at regular intervals, which is worth remembering when a chart shows sells nobody seems to have made.
Stock Dividends and Stock Pairs
What Flap brought to Robinhood Chain on 9 July was a way to spend that tax on stocks. A tax coin can route its revenue into a Stocks Vault, which pays holders in a basket of one or more Robinhood stock tokens; the first list was AAPL, GOOGL, NVDA, PLTR, SPCX and SPY. Holders receive the vault's basket token, which unwraps into the underlying stocks. On 24 July Flap added stock-paired coins, where the stock is also the currency the coin trades in, and its contracts on the chain now accept ETH, USDG and stock tokens as pairs.
The dividend is real but it has a source: every payout was a tax on someone's trade. A coin with a busy chart pays holders well and costs traders a lot, and a quiet one does neither. Robinhood's terms also restrict who can own those stock tokens, which matters here twice over, as the pair and as the payout.
Flap Coins in Axiom's Pulse
On BNB, tick Flap in the protocol filter; on HOOD, tick Flap for plain coins, Flap Tax for taxed ones, or both. The contract address usually tells them apart at a glance, since Flap's launcher grinds plain coins to end in 8888 and tax coins to end in 7777. The two columns behave nothing alike. On BNB new coins arrive every few seconds and a large share come from launch bots, so set holder and volume floors before you read anything. On HOOD, with Pons taking most of the chain's launches, a Flap column moves slowly: DefiLlama counted about $69,000 of Flap volume on Robinhood Chain in the last full day, and reading each coin properly matters more than filters.
Final Stretch shows Flap curves that are close to their 80% mark, and graduation is the moment liquidity changes shape, from a fixed curve to a pool anyone can add to.
Flap Trading Bot
A plain Flap coin gets cheaper to trade once it graduates; a taxed one never does.
On the curve a plain coin costs Flap's 1% plus Axiom's 0.8% with TradeNow on each side, roughly 3.6% in and out. After graduation Flap's fee stops and the pool's own fee takes its place: 0.3% on a Uniswap V2 pool on Robinhood Chain and 0.25% on a PancakeSwap V2 pair on BNB, so the round trip falls to a little over 2%. A tax coin adds its own buy and sell tax to either figure for as long as the tax exists. Exits set as limit orders on the chart save you from chasing a thin book.
Flap Sniper Bot
With no pool to race until graduation, a Flap snipe is a curve trade.
The opening buys all go through the same curve at prices set by the formula, so the edge is timing rather than routing. The better-known window is graduation: a curve near 80% will open its DEX pool in the transaction that fills it, and that is the moment worth keeping a separate preset for. On BNB it happens often enough to plan around, with blocks every 0.45 seconds and 97 graduations in the 24 hours we counted. On a plain coin, remember the anti-farmer window: only the main pool works for a while, so the pool you meant to use may simply refuse the trade. The memecoin sniper page walks through the feed filters for both chains.
BNB Chain and Robinhood Chain Settings for Flap
On BNB Chain every transaction's gas comes out of BNB, whatever the coin is priced in, so a stock-paired buy still needs a little BNB beside it. Axiom can send BNB orders through a private route, out of reach of the sandwich bots that work PancakeSwap, which counts most in the first minutes after a coin graduates. The BNB Chain page covers that side, and the Four.meme page covers the other big launchpad there.
Flap trades land through Robinhood Chain's first-come sequencer, where speed depends on how directly a transaction reaches it rather than on the fee attached. The Express Lander amount under Priority in your Axiom presets is that lever, 0.001 ETH unless you change it; it matters on a busy graduation and hardly at all on a quiet curve. The Robinhood Chain page explains the chain, and the Pons page covers the chain's biggest pad.
Flap So Far
Flap came out of an ETHGlobal hackathon and started on BNB Chain in 2024, where it built its reputation for programmable taxes and vaults that route them to holders. For most of its first two years it traded well behind Four.meme. That changed in August 2026, when DefiLlama's count of its BNB curve volume jumped from $79 million in July to $734 million. It went live on Robinhood Chain on 9 July 2026, a week after the chain's mainnet, with Tax Token V3 and Stocks Vaults, and added stock-paired coins two weeks later.
Its recent announcements have been about new quote assets, such as a short-term Treasuries fund and pre-IPO shares, and vaults that tie a coin to its own perpetual market. On Robinhood Chain it is a second-tier venue, with about $7.9 million of volume over the last 30 days against Pons' $2.37 billion.
Where Flap Bites
The sell tax, above all. A Flap Tax coin can advertise a small buy tax and charge much more on the way out, and the automatic tax sales add selling of their own after graduation. Read both rates before the first buy.
Thin books come next. With modest volume on Robinhood Chain, a young Flap pool can move hard on an ordinary order, and a stock-paired coin adds the stock's own swings on top.
On BNB the problem is the reverse: too much, not too little. Launch bots produce a large part of each day's new coins, many with the tax set near the top of the range, so a coin's age, holders and sell tax say more than its spot in the feed.

Flap on Axiom — FAQ
Can I buy Flap coins through Axiom?
Yes, on both chains. Flap is in Axiom's BNB protocol filter, Flap and Flap Tax are the third and fourth entries on Robinhood Chain, and Flap lists Axiom among the terminals that support its tokens.
Should I trade Flap coins on Axiom or flap.sh?
Launch on flap.sh. For trading, Axiom puts BNB Chain and Robinhood Chain in one account, shows Flap next to Four.meme, routes BNB orders privately and fires migration orders at graduation.
What is the difference between Flap and Flap Tax?
Flap coins are plain tokens with no tax. Flap Tax coins charge a creator-set buy and sell tax on every trade, which can fund holder dividends such as stock tokens.
When does a Flap coin graduate on BNB Chain?
When 800 million tokens have sold on the curve, which on a BNB pair means about 16 BNB raised. Plain coins then move to PancakeSwap V3 and tax coins to a PancakeSwap V2 pair.
When does a Flap coin graduate on Robinhood Chain?
When 80% of its supply has sold on the bonding curve, at about 5 ETH raised on an ETH pair. The rest of the supply and the reserve then become a Uniswap V2 pool.
What does it cost to trade a Flap coin?
Flap takes 1% of each curve trade and nothing once a coin has graduated, when the pool's fee applies instead: 0.3% on Uniswap V2 on Robinhood Chain, 0.25% on a PancakeSwap V2 pair on BNB. Tax coins add their own tax on top. Axiom's own fee is 1%, or 0.8% with TradeNow.
How do Flap stock dividends work?
A tax coin can send its tax to a Stocks Vault that pays holders in a basket of tokenized Robinhood shares, for example Nvidia and Palantir. Holders receive the vault's basket token, which unwraps into the stocks.
How can I tell a Flap coin by its address?
On both BNB Chain and Robinhood Chain, Flap's launcher gives plain coins contract addresses ending in 8888 and tax coins addresses ending in 7777.
Is Axiom affiliated with Flap?
No. Axiom reads Flap's contracts and trades the pools its coins graduate into; flap.sh is Flap's own site.
