Four.meme BSC Launch
Launch a BNB Smart Chain token through Four.meme with fixed launch parameters, optional tax settings, BSC bundle buys, and starter strategies.
Sumo supports Four.meme BSC launches on BNB Smart Chain. Four.meme is not a Uniswap-style pool launch: Sumo obtains the create transaction through the Four.meme API, predicts the token address, builds bundle buys against the Four.meme curve, and submits the launch atomically through BSC bundle builders.
Prerequisites
Before launching, make sure you have:
- Token metadata ready: name, ticker, image, description, and social links
- BNB for token creation, dev buy, bundle buys, gas reserves, and bundle priority fee
- A launch plan: target supply control, dev buy, bundle wallet count, and optional tax settings
- A wallet plan: use ready wallets from private keys, Wallet Farm, or another profile, or create new BSC wallets / buy aged BSC wallets through Wallet Marketplace during the wizard
Fixed Four.meme Parameters
Four.meme fixes total supply at 1 billion tokens with 18 decimals, BNB as the quote asset, 80% sale allocation, 24 BNB raised amount, and PancakeSwap as the migration DEX.
Launch Flow
1. Info
Choose Four.meme BSC in the Launchpad field, then enter the token and profile details.
| Field | Required | Description |
|---|---|---|
| Launchpad | Yes | Select Four.meme BSC. The launchpad is locked after the draft is saved. |
| Profile Name | Yes | Internal Sumo profile name used after launch |
| Token Name | Yes | Public token name |
| Ticker | Yes | Public token symbol, auto-uppercased |
| Image | Yes | JPG or PNG image, uploaded to Four.meme when saved |
| Description | No | Public token description |
| X, Telegram, Website | No | Public social links included with the Four.meme metadata |
Total supply and decimals are fixed by Four.meme and are not edited in the standard Sumo flow.
2. Buy Mode
Four.meme uses BNB buy planning against the Four.meme curve.
| Setting | Description |
|---|---|
| Supply Control Target | Total supply controlled by dev and bundle wallets. Four.meme is capped at 80%. |
| Dev Buy | Initial BNB buy submitted with token creation. The default is 1%. |
| Bundle Buy | Allocation assigned across bundle wallets after the create transaction. |
| Bundle Wallets | Number of BSC wallets used for bundle buys. Four.meme supports 1 to 48 bundle wallets. |
| Estimated BNB Required | Create value, dev buy, bundle buys, gas reserve, and funding buffers when enabled. |
| Estimated Market Cap | Estimated from Four.meme curve math and BNB/USD reference price. |
| Funds Per Bundle Wallet | BNB gas reserve per bundle wallet. |
| CEX Funding | Optional Husher funding path for distributing BNB. |
| CEX Funding Buffer Per Wallet | Extra BNB added per wallet when CEX funding is enabled. |
| Advanced Controls | Supply jitter, BSC bundle priority fee, and funding delay controls. |
Tax Controls
Four.meme tax settings are different from the shared Uniswap-style tax contract.
| Setting | Description |
|---|---|
| Buy Fee Rate | Four.meme buy fee preset. Allowed values are 1%, 3%, 5%, and 10%. |
| Sell Fee Rate | Four.meme sell fee preset. Allowed values are 1%, 3%, 5%, and 10%. |
| Burn Rate | Percentage of collected tax allocated to burn. |
| Divide Rate | Percentage of collected tax allocated to dividend/distribution behavior. |
| Recipient Rate | Percentage of collected tax allocated to the tax recipient wallet. Defaults to 100%. |
| Liquidity Rate | Read-only remainder after burn, divide, and recipient rates. |
| Tax Wallet | Wallet used as the tax recipient when tax is enabled. |
The four split rates must add up to 100%. In the wizard, liquidity rate is derived from the other three values.
3. Wallets
Add, import, or generate wallets for each required BSC role.
| Role | Description |
|---|---|
| Dev Wallet | Authenticates with Four.meme, uploads metadata, creates the token, pays create value, and performs the dev buy. |
| Bundle Wallets | Execute Four.meme curve buys in the BSC launch bundle. |
| Tax Wallet | Required only when Four.meme tax is enabled. |
You can use ready wallets, create new wallets, or buy aged wallets at this step. Ready-wallet paths include importing private keys, pulling wallets from Wallet Farm, or reusing wallets from another profile. Additional paths include creating new wallets or buying aged inventory from Wallet Marketplace.
Holder, sniper, and injection wallets are not used by Four.meme BSC launches.
4. Funding
Save the draft before funding. Sumo uploads the image to Four.meme when needed and stores the Four.meme image URL on the launch draft.
The funding table tracks BNB requirements for token creation, dev buy, bundle buys, gas reserves, and BSC bundle priority fee. If CEX funding is enabled, deposit the estimated BNB into the funding wallet and use Fund to distribute it through Husher. If CEX funding is disabled, fund the dev and bundle wallets directly and use Check Balances.
5. Strategies
Optionally add starter strategies to the profile before launch. These strategies are saved with the draft and can be reviewed after the token is live.
6. Launch Preview
The preview shows:
- Four.meme metadata and uploaded image status
- Predicted token address
- Dev and bundle wallet counts
- BNB funding rows
- Supply split across dev and bundle buys
- Optional tax configuration and tax wallet
When launched, Sumo builds the Four.meme create transaction, appends bundle buys, simulates the BSC bundle, submits it to supported BSC builders, and confirms the landed transactions on-chain.
After Launch
When the bundle lands, the profile becomes active and opens in Live Trading. Four.meme profiles use the Four.meme connector for quotes, trades, migration progress, and post-launch spot-price data.
Launch Logs
Four.meme profiles add a Launch Logs tab for metadata upload, create transaction preparation, bundle simulation, bundle submission, and confirmation.
