Four.meme is a web launchpad for creating, discovering and trading tokens on BNB Smart Chain. Its current creation interface offers Classic Mode for bonding-curve launches and Open Mode for launches built with OpenFour contract modules.
Feature scope: fixed supply and automatic graduation to PancakeSwap describe the documented Classic launch path. Open Mode uses separate modules; do not apply Classic supply, migration or fee assumptions to every Open launch.
From a Classic launch to a liquidity pool
In Classic Mode, early trades follow a bonding curve: a formula changes the price as tokens are bought or sold. When the launch reaches full progress, liquidity migrates to PancakeSwap. The selected quote asset is the currency used for the launch's trading pair. The form currently includes BNB, USDT, USD1 and UUSD, alongside eligible bStocks quote assets; these are assets on the supported network, not additional blockchains.
Open Mode uses a separate modular launch engine. Creators select a contract preset and enter its parameters. Classic launch assumptions should not be applied automatically to OpenFour modules.
Access and suitability
Useful for: creators launching BNB Chain tokens and users following their trading activity and graduation progress.
Less suited to: creating native Solana tokens or designing arbitrary contract logic through the Classic form, whose technical launch parameters are mostly preset.
Account and wallet: public listings and the creation form can be viewed without signing in. Creation uses wallet authentication; creating tokens or submitting trades requires a BNB Smart Chain wallet and BNB for network gas.
Installation: the browser interface requires no separate Four.meme application. Developer integrations and the optional agent CLI are separate workflows.
Costs and launch settings
Protocol trading fees, network gas and any token-specific buy or sell tax are separate costs. With Antisniper enabled, opening-block trading fees start higher and decrease over successive blocks. A single fixed percentage does not describe every launch.
The Classic form offers separate buy and sell tax settings and allocations to a recipient wallet, burning, holder distributions, liquidity and supported charities. Here, a token tax is a transfer or trading charge built into the token, not a tax-return service. Memecoins can lose their value; neither the launch mechanism nor graduation guarantees trading demand or a financial outcome.
