Four.meme Launch
Launch on Four.meme's bonding curve with up to 30 wallets buying in the launch block.
Four.meme is the main memecoin launchpad on BNB Chain. The price follows a bonding curve. When about 18 BNB has been raised, the token graduates to PancakeSwap. Supply is fixed at 1,000,000,000 and there is no launch fee. Four.meme Launch creates the token with your dev buy and adds up to 30 bundle-wallet buys. All of it goes out as one atomic bundle to BSC builders, so the buys land in the launch block, right behind it, or nothing lands.
Step 1: Token and dev wallet
Token details
Four.meme requires an image, a Token name, a Ticker and a description. You also pick a category (Meme, AI, Defi, Games, Infra, De-Sci, Social, Depin, Charity or Others). Website, Twitter and Telegram links are optional.
Dev wallet
| Field | Notes |
|---|---|
| Dev wallet | Pre-filled with your ★ default dev wallet. It signs in to Four.meme and becomes the token's creator there |
| Dev buy (BNB) | Bought inside the createToken transaction itself. Optional |
Step 2: Bundled buy wallets
Click wallets to add them (up to 30, not counting the dev wallet). Set an amount for each, use the quick buttons (0.05 / 0.1 / 0.5), or enter BNB for all and click Apply to selected. 🎲 Randomize gives each selected wallet a random amount between 85% and 100% of that value, so the buys aren't identical. Keep about 0.0005 BNB extra in each wallet for gas.
Total to launch adds up the dev buy, the bundle buys and TokenBundle's 2% fee. Four.meme's own 1% trading fee is taken out of each buy amount.
Launch
- Sign in to Four.memeThe dev wallet signs Four.meme's login message, the image is uploaded to Four.meme, and Four.meme returns a signed launch for that wallet.
- SimulateThe launch and every buy are dry-run in bundle order on current chain state. This gives the token address before anything is sent, and the exact amount each wallet will receive. Each buy is then signed with a 5% floor under that amount. If any buy would fail, nothing is sent.
- One bundleThe bundle is
createToken, then each wallet'sbuyTokenAMAP, then the fee transfer last. It goes to 48 Club and BlockRazor for the next ~40 blocks (~18 s).

8/8 bundled buy(s) landed.On success you get links to Four.meme and BscScan, and Open Terminal →, which opens the token in the Terminal. The Terminal spots Four.meme tokens by itself. It trades on the curve until the token graduates, then through the 0x aggregator (PancakeSwap and the other BNB Chain DEXes).
