What is Four.meme? BNB Chain's memecoin launchpad
The Editor·7 min read·Updated 31 Aug 2026
What is Four.meme: the BNB Chain launchpad's bonding curve, its ~0.005 BNB creation cost and 1% trading fee, PancakeSwap migration, and two 2025 exploits.
Four.meme is a bonding-curve memecoin launchpad on BNB Smart Chain. You pay roughly 0.005 BNB to create a token, trading on the curve carries a 1% fee, and a token that fills its curve migrates to PancakeSwap. It is BNB's largest launch venue and ranked seventh among all launchpads by total value locked on 31 August 2026.
How Four.meme works
The mechanism is the standard bonding-curve model. A creator supplies a name, ticker and image and pays a creation fee of about 0.005 BNB. The contract mints a fixed supply and prices it along a curve: each buy pushes the price up, each sell pushes it down, and there is no order book and no counterparty other than the curve itself. Every trade on the curve pays a 1% fee to the protocol.
When enough of the supply has been bought, the token migrates to PancakeSwap — BNB Chain's dominant DEX — and the curve stops being the venue. From that point the token trades in a normal automated market maker pool and its price is set by whoever is willing to buy and sell there. If the mechanics of that transition are new to you, what graduation means on a memecoin launchpad covers what changes at the moment of migration and what does not.
Four.meme is BNB Smart Chain only. There is no Solana, Base or Ethereum deployment.
Four.meme fees, in one table
| Item | Amount |
|---|---|
| Token creation | ~0.005 BNB |
| Trading fee on the curve | 1% |
| Migration target | PancakeSwap |
| Chains supported | BNB Smart Chain only |
The 1% headline is in line with the wider market — pump.fun charges 1.25% total, Pons charges 1% on Robinhood Chain — and materially above the 0.25% that Uniswap's Pools.trade set on Robinhood Chain in August 2026. The fee you pay as a buyer is not just this number, though: on BNB you also pay gas on every transaction and you lose something to slippage on a thin curve. Read a live quote rather than assuming 1% is your total cost.
How big is Four.meme now
As of 31 August 2026, DefiLlama reported Four.meme at $4.39 million TVL, $388,324 of fees over 30 days, $385,064 of revenue over the same period, and $118.15 million of DEX volume in 30 days. Cumulative DEX volume across the protocol's life stands at $9.905 billion. That places it seventh among launchpads by TVL.
Two things stand out. The first is the gap between $9.905 billion cumulative and $118 million in the most recent month — this is a venue well past its peak, with the great majority of its lifetime volume already behind it. The second is that fees and revenue are almost identical, $388,324 against $385,064. Four.meme keeps essentially all of what it charges. That is a meaningfully different posture from creator-fee launchpads like Bags or Pons, where most of the take passes through to token creators, and it matters if you are choosing a venue as a launcher rather than a buyer. How launchpad fee splits actually work sets out the difference between the two models.
For chain-level context: memecoin issuance in 2026 consolidated onto Solana and Robinhood Chain, with BNB a distant third. Four.meme is the biggest venue on that distant third.
The two security incidents you should know about
Four.meme was exploited twice in 2025, and both are worth stating rather than skipping.
In February 2025 the protocol lost approximately $183,000 to a flaw in its swap logic. In March 2025 it lost approximately $80,000 to an access control vulnerability. Neither is catastrophic by the standards of DeFi exploits, and neither is recent, but two separate contract-level failures inside two months tells you something about the code's maturity at the time.
What it does not tell you is anything about the current state of the contracts. We have no audit to point at and no public post-incident report to summarise. Treat this as history that should raise your baseline scepticism about the venue's contracts, not as evidence of a live vulnerability.
The more common way to lose money on any launchpad has nothing to do with protocol exploits. It is the token, not the venue: a creator who holds most of the supply and sells it, a pool with liquidity that was never locked, or a contract with a transfer restriction that lets you buy and not sell. Those checks apply on Four.meme exactly as they do anywhere else, and how to spot a memecoin rug pull before you buy is the workflow to run before you commit.
Who else launches on BNB
Four.meme is the largest but not the only venue. Flap.sh started on BNB and has since gone multichain, running $2.68 million in 7-day fees across four chains as of 31 August 2026 with full revenue capture — Flap.sh's stock-token payout model is the genuinely unusual thing about it. GraFun is also named as a BNB venue, but the sourcing we could find for it is Chinese-language only and we have not independently verified its scale, so treat any figure you see attached to it with caution.
If you are approaching BNB as a buyer rather than a launcher, the practical mechanics — wallet, gas, finding the right contract — are in how to buy memecoins on BNB Chain. Venue-level launch and volume data across chains sits in the Meme Central analytics hub.
What this page does not tell you
The fee and volume figures above are DefiLlama's as of 31 August 2026 and will drift. The ~0.005 BNB creation cost is what Four.meme's own mechanism documents; the BNB-denominated figure means your cost in dollars moves with BNB, so treat it as an order of magnitude rather than a price.
We have not verified graduation rates specifically for Four.meme. Across the wider market, the defensible range for the share of tokens that ever reach a DEX is somewhere in the low single digits at best, and any single figure quoted without a measurement window is close to meaningless — see why so few memecoins graduate. Assume Four.meme is not an exception.
Frequently asked questions
How much does it cost to create a token on Four.meme?
Around 0.005 BNB for the creation transaction itself, plus BNB gas. The larger cost is usually not the fee but the 1% charged on every trade along the bonding curve, which comes out of buyer and seller flow rather than your wallet directly. Because the fee is denominated in BNB, your dollar cost moves with BNB.
Where do Four.meme tokens go after they graduate?
To PancakeSwap, BNB Chain's dominant decentralised exchange. Migration ends the bonding curve and moves trading into a standard AMM pool. The token's contract does not change, so the address you were watching on the curve is the address you trade afterwards — but liquidity depth, slippage and price behaviour all change at that moment.
Is Four.meme safe to use?
It has been exploited twice: about $183,000 in February 2025 from a swap logic flaw, and about $80,000 in March 2025 from an access control vulnerability. Both are old and neither is evidence of a current problem, but the venue's contracts have a track record. Separately, venue safety says nothing about the safety of individual tokens launched on it.
Is Four.meme still active in 2026?
Yes, but much diminished. As of 31 August 2026 it had $4.39 million TVL and $118.15 million of DEX volume over 30 days, against $9.905 billion cumulative over its lifetime. It remains the largest launchpad on BNB Chain and ranks seventh among all launchpads by TVL.
Can I launch on Four.meme from another chain?
No. Four.meme is deployed on BNB Smart Chain only. You need BNB in a wallet connected to BNB Chain to create or trade. If your funds are elsewhere you will have to bridge first, and bridging costs and delays should be part of your calculation before you start.
A lock is the one claim a buyer can verify without trusting you
Four.meme handles liquidity automatically at migration, but the moment a token trades on PancakeSwap the question a buyer asks is whether that liquidity can be pulled. Team Finance — built by TrustSwap, which also builds Meme Central — locks LP tokens for a fixed term across Ethereum, Robinhood Chain, Polygon, Base and BNB, and the lock appears as a verified badge on that token's page in the Meme Central feed. It does not stop a creator selling their own allocation, and it is not a substitute for the contract checks above.
Nothing here is financial, legal or tax advice. Memecoins are extremely high-risk: most lose most of their value, and the majority of tokens launched never reach a decentralised exchange at all. Never spend money you cannot afford to lose entirely. Meme Central does not recommend any specific token. Data described as Meme Central's own reflects tokens indexed by Meme Central and is not whole-market data.
