Four.meme Guide (2026): How to Buy BNB Chain Memecoins

Four.meme is the main memecoin launchpad on BNB Chain: a coin starts on a bonding curve and, at about 18 BNB, it graduates to a PancakeSwap pool. To buy four meme coins, you need BNB in a wallet on BNB Smart Chain and the coin's contract address. We use BasedBot as the main route, because the same bot also trades on Base and Solana.

What is four.meme?

Four.meme is a launchpad for meme tokens on BSC (BNB Smart Chain). Its docs (opens in a new tab) call it a "low-cost pathway" to launch memecoins. It does on BNB Chain what pump.fun does on Solana.

The facts from the official how it works page (opens in a new tab):

• Supply: every memecoin launched on four.meme has a preset total supply of 1,000,000,000 tokens.
• Launch cost: launching is free, apart from a network fee of about 0.005 BNB.
• Trading fee: 1% on trades on the platform, with a minimum of 0.001 BNB.
• Trading pair: the creator picks the token that the internal pool trades against. The docs name BNB, USDT, USD1, UUSD and bStocks.
• Dev buy: the developer can buy part of the supply in the launch transaction, which the docs say protects the coin from snipers.

How the four.meme bonding curve and graduation work

A new four.meme coin does not start with a normal pool. It trades on a bonding curve: each buy raises the price and each sell lowers it, so early buyers pay less. There is no order book and no outside liquidity pool at this stage.

The curve has a target. When the coin reaches 100% of the bonding curve, about 18 BNB, four.meme starts the seeding process. It pairs 20% of the token supply with all the funds the curve collected and opens a pool on PancakeSwap. This step is the graduation. After it, anyone can trade the coin on PancakeSwap, and DEX tools and bots treat it like any other BSC token.

What this means for you:

• Before graduation, the price moves fast on small buys, and the dev and early wallets often hold a large share.
• At graduation, many holders sell into the new pool. A rug pull or a dump often happens near this point.
• After graduation, your price impact depends on the PancakeSwap pool, which starts with the funds the curve raised (about 18 BNB on a BNB pair) and 20% of the supply.

Four.meme also has Tax Tokens. Per the Tax Tokens page (opens in a new tab), the creator picks a tax of 1%, 3%, 5% or 10% that applies to each eligible trade, on the curve and after graduation. The tax can go to a creator wallet, to holders, to a burn or to liquidity. The same page describes an optional anti-sniping mode with high fees in the first few blocks after launch.

How to buy four.meme coins with BasedBot

BasedBot is a self-custody Telegram bot and web app. Its supported networks page (opens in a new tab) lists BSC, Base, Solana and 13 more networks, and it names Four.Meme among the supported launchpads. Its live channels page (opens in a new tab) lists a Four.Meme (BSC) channel for new tokens, with a fast-buy button. Because the bot detects the chain from the pasted address, you keep one tool when you switch from a BNB memecoin to a Base or Solana coin. The steps below come from the BasedBot docs. For the full setup, read our BasedBot tutorial.

1. 1

   Open BasedBot from an official link

   Open basedbot.app/r/START (code START doubles your cashback to 10–50%), or search @based_eth_bot in Telegram. Type /start to open the main menu. See the setup page (opens in a new tab).
2. 2

   Create or import a wallet

   Tap Wallet or type /wallet, then tap an empty slot. Choose "Create a new wallet" or "Import a wallet" with its private key. Per the wallets page (opens in a new tab), importing into a used slot replaces the old wallet, so save the old key first.
3. 3

   Send BNB to the wallet

   Tap the wallet address to copy it and send BNB on BNB Smart Chain. BNB is the native coin on BSC, per the bridge page (opens in a new tab). If your funds are on Base or Solana, type /bridge and move ETH or SOL to BNB.
4. 4

   Configure BSC settings

   Open /settings. Turn on MEV protection, which the settings page (opens in a new tab) lists for ETH, BASE and BSC. Set your slippage and turn on Dev Sell if you want the bot to sell when the developer sells.
5. 5

   Paste the contract address and run the audit

   Copy the address from the coin's four.meme page or its official X account and paste it into the bot. Tap Audit: the audit page (opens in a new tab) says it shows buy, sell and transfer taxes, Burn %, Clogged % and MaxTx.
6. 6

   Buy and set your exits

   Tap a preset amount or a custom amount. Then set Take Profit, Stop Loss or a Trailing Stop Loss on the token monitor, as the TP/SL page (opens in a new tab) shows.
7. 7

   Sell from /manage

   Type /manage, tap the token and choose a sell button or X% for a custom amount. The ❌ button only hides a position; it does not sell.

Two BasedBot tools fit four.meme well. The Migration Sniper lets you place a Migration Buy or Migration Sell order on a token, per the Migration Sniper page (opens in a new tab). The docs do not name the launchpads it covers, so check in app that it fires on a four.meme graduation. The web app Pulse feed shows bonding-curve tokens with a progress indicator, per the Pulse page (opens in a new tab).

Alternatives: Banana Gun, Maestro and GMGN

All three trade on BNB Chain, and Locke traded on each with real money. Each has a trade-off that matters on a fast launchpad.

• Banana Gun: its docs list PancakeSwap and Four.meme on BNB Chain, and it charges 0.5% on manual trades and 1% on snipes. In September 2024, an exploit drained about $3 million from 11 users; Banana Gun promised full refunds. See the Banana Gun review.
• Maestro: twelve chains, including BSC, with Auto Snipe on BSC. The fee is 1% with 15–30% cashback, and the bot stores your keys encrypted on its servers. See the Maestro review and Banana Gun vs Maestro.
• GMGN: strong charts and wallet tracking on BNB Chain, at 1% per trade. You cannot export the private key, and in October 2025 sandwich attacks on its BNB Chain anti-MEV nodes hit 729 trades (users were reimbursed). See the GMGN review.

How to check a four.meme coin for rugs

Do these checks before every buy. Most of them take less than a minute in a bot or on the token page.

1. Contract address: copy it from the four.meme token page or the project's official X account. Fake coins copy the name and the ticker. Never use an address from a DM.
2. Tax: check if the coin is a Tax Token and how high the tax is. A 10% tax on the buy and on the sell costs you about 20% on a round trip. BasedBot's Audit shows buy and sell taxes.
3. Dev wallet: the dev can buy supply in the launch transaction. Check the dev wallet share. BasedBot's web token page shows Dev Holding %, per the token page docs (opens in a new tab).
4. Top holders, snipers and bundles: a few wallets with a large share can dump on you. The same page shows Top 10 Holders %, Snipers, Insiders and Bundlers. Read about bundling.
5. Curve progress: a coin near 100% is near graduation. Expect volatility and sells into the new PancakeSwap pool.
6. Sell path: buy a small amount, then sell part of it. If the sell fails, the coin can be a honeypot.
7. MEV: on BSC, sandwich attacks are common. Turn on MEV protection and keep slippage as low as the trade allows.

The full red-flag list and real cases are in our guide to rug pulls.

Fees to expect

If a bot routes your buy through the four.meme curve, the launchpad fee and the bot fee can both apply. Check the total on the confirm screen. BasedBot pays cashback in the native coin of the chain, so a BSC trade earns BNB, and you claim it with /cashback from $10 per chain. The code is on our BasedBot referral code page.

Mistakes to avoid

• Do not buy by ticker. Many four.meme coins share a name. Buy only by the contract address.
• Do not skip the tax check. A high tax makes a small win a loss.
• Do not chase a coin at 95% of the curve. Graduation often brings a wave of sells.
• Do not answer DMs from "support". The BasedBot team never DMs first and never asks for your private key, per its support page (opens in a new tab).
• Do not keep savings in a bot wallet. Keep only trading money there.
• Do not open bots from ads or search results. Use our official links page.

Bottom line

Four.meme is where most new BNB memecoins start: a 1 billion supply, a bonding curve to about 18 BNB, then a PancakeSwap pool. If you want one tool for BNB Chain, Base and Solana, use BasedBot with code START for 10–50% cashback. New to memecoins? Start with how to buy memecoins.
