# Flap.sh review Canonical page: https://memefees.com/reviews/flap-sh Editorial review date: 2026-10-01. This is not a live-data timestamp. BNB Chain token launches with bonding curves, configurable taxes and payout vaults. ### Verdict Flap.sh combines bonding-curve launches with token-specific tax and payout settings. This review covers its BNB Chain activity. The official fee documentation separates ordinary curve trades from tax tokens, so the token type changes the cost. A non-tax token pays a 1% curve fee on BNB Chain. A tax token adds its own tax on the curve and keeps the tax after DEX migration. Flap also takes a protocol rate of up to 0.3% of volume on tax tokens. ### Pros - Public documentation explains prebond taxes and payout contracts - Token-specific settings support different recipient and holder allocations - Bonding curves provide an initial trading venue before DEX migration - Flap says its website and supported terminals show tax vault details ### Cons - A token's configured tax increases the cost above the base curve fee - Payout rights depend on contract configuration and recipient settings - DEX migration does not remove a tax token's own charges - Tax tokens can migrate only to V2-type pools, not to concentrated-liquidity pools ### Best for - Creators who need configurable token-tax distribution - BNB Chain traders willing to inspect the settings of each launch - Users comparing tax-token designs with ordinary bonding-curve tokens ### Skip it if - You assume every token uses the same total trading fee - You need a universal, fixed creator-payout percentage - You expect launch costs or post-migration charges to be identical across tokens ### What Flap.sh is Flap.sh is an EVM token-launch protocol with bonding curves, tax tokens and configurable payout vaults. This page focuses on BNB Chain. Flap's contract list also names Robinhood Chain, Base, X Layer and Monad, and its fee page names Morph. Our activity figures use DefiLlama's Flap.sh adapter, which reports BSC, X Layer, Monad and Robinhood Chain. Flap docs list GMGN and Axiom among the terminals that trade Flap tokens. CertiK and BlockSec audited earlier Flap protocol versions, according to the Flap audit page. ### Launch costs and migration The Flap create page shows a deploy cost of around 0.001 BNB. A creator can make an optional first purchase of up to 20M tokens to reduce sniper activity. The page refunds any overpayment. When buyers hold 800M of the 1,000M token supply, the token lists on a DEX with the remaining tokens and the curve reserve as liquidity. On BNB Chain, the docs name PancakeSwap as the only DEX target. A non-tax token goes to a V3-type pool first and falls back to V2. A tax token goes only to a V2-type pool. ### Base fees and token taxes The documented BNB Chain bonding-curve fee for a non-tax token is 1%. A tax token adds its own configured tax: the official prebond example combines a 3% token tax with the 1% base fee for a 4% effective curve charge. Tax rates are 1%, 3%, 5% or 10%, and Tax Token V3 can set different buy and sell rates. The 1% curve fee stops at graduation. After migration, token taxes apply to DEX trades together with the pool fee. Flap adds a protocol rate of up to 0.3% of volume on tax tokens, and the exact rate is in the protocol contract. ### Where tax proceeds go Flap Tax Token V2 documentation describes configurable allocations to a funds recipient, a market address, holder dividends and buyback or burn functions. Which recipients receive funds depends on the configuration; there is no single creator percentage that applies to every Flap token. Dividend contracts can impose eligibility conditions, including a minimum holding balance and excluded addresses. The Flap Tax Trigger Bot calls dispatch and pays the gas. Anyone else can also call dispatch, and the dividend amount depends on the tax that trades produce. ### How it compares Flap.sh and four.meme both run bonding-curve launches on BNB Chain. In a four.meme vs Flap.sh comparison, the Flap tax-token options and tax vaults are the main difference. A Flap tax token can cost a trader more than the 1% base fee. MemeFees holds no Flap referral code. The Flap docs index lists no referral program. ### Frequently asked questions ### How much does trading on Flap.sh cost? The documented BNB Chain non-tax curve fee is 1%. Tax tokens add their configured tax and a protocol rate of up to 0.3% of volume. After migration, the token tax and the pool fee apply. ### Do all Flap creators receive the same fee share? No universal rate is documented. Tax vaults allocate funds according to token-specific recipient, holder, buyback and burn settings. ### Is Flap.sh free to launch on? No. The create page shows a deploy cost of around 0.001 BNB plus network gas. A first creator purchase is optional. ### Does this page cover every Flap deployment? No. This profile covers BNB Chain. Flap docs also list Robinhood Chain, Base, X Layer, Monad and Morph.
