FAQ
Is this the same as launching on letsbonk.fun?

letsbonk.fun or Raydium?
letsbonk.fun's fee funds BONK burns; Raydium sends 10% of its share to your creator vault.

Once 85 SOL has been raised on the curve, it migrates to a Raydium CPMM pool.

What the letsbonk.fun Launcher does
Two platforms, one form
Launch under letsbonk.fun's platform or Raydium LaunchLab's own. The choice sets the trade fee, the listing site and who gets the platform's share.
Built with Raydium's SDK
The pool is built with Raydium's official SDK, bound to your RPC and wallet, with no calls to Raydium's or letsbonk.fun's servers.
Atomic or nothing
If the launch would need more than one transaction, it is refused, so pool creation and your first buy can never be split.
Dev buy with a floor
The result shows the tokens your dev buy received and the minimum your slippage allowed, next to links for the mint and the curve pool.
Devnet rehearsal
On devnet the same transaction runs on Raydium's test platform, so you can rehearse with test SOL before a mainnet launch.
Fees in one place
The coin is saved to My Solana Tokens, and your LaunchLab creator vault shows in Creator Fees.
Solstack vs other letsbonk.fun launchers
A choice of LaunchLab platform and a single-wallet launch, where most tools offer only letsbonk.fun and many add bundled wallets.
Solstack letsbonk.fun Launcher
- Choose letsbonk.fun's platform or Raydium's own, which pays 10% of its fee share into your creator vault
- Your dev buy comes from the creating wallet and shows on-chain as the creator's buy
- Never asks for a private key; you approve the launch in your own wallet
- Rehearse the identical launch on devnet with test SOL
Typical letsbonk.fun launch tool
- Usually letsbonk.fun's platform only
- Bundlers add extra buying wallets: up to 4 on one tool, 12 on another
- Bundlers often generate wallets in the browser or take a pasted dev-wallet key
- Usually mainnet only
letsbonk.fun Launcher: Complete Guide
What is Raydium LaunchLab?
LaunchLab is Raydium's bonding-curve program and the one letsbonk.fun itself runs on — this talks to the same program and platform id directly, so the coin shows up on letsbonk.fun without going through their site.
Pick letsbonk.fun's platform config or Raydium's own, set an optional first buy, and launch in one signed transaction.
letsbonk.fun or Raydium?
- letsbonk.fun: a 1.25% trade fee on the curve. The platform's share pays for BONK burns, and the coin lists on letsbonk.fun.
- Raydium LaunchLab: a 0.75% trade fee. 10% of the platform's share goes into your creator vault, and the coin lists on Raydium's launchpad.
- Both: 1,000,000,000 supply with 6 decimals on a constant-product curve: 732.5M of it on the curve on letsbonk.fun, 793.1M on Raydium. The coin moves to a Raydium CPMM pool once 85 SOL has been raised, and the program holds mint and freeze authority.
Same program, no detour
letsbonk.fun is a website on top of LaunchLab. Solstack sends LaunchLab the identical initialize instruction, with letsbonk.fun's platform id and the same curve settings, straight from your browser, so the site indexes your coin like any other letsbonk.fun launch. Pool creation, your first buy and the 0.05 SOL fee land in one transaction, so no one can buy between them.
Before you launch
- Have the name, ticker, a square logo and links ready. They're written into the metadata and can't be changed after launch.
- Choose the platform, which sets the trade fee and where the platform's cut goes.
- Choose a dev buy amount, or none.
- On devnet only Raydium's test platform exists, so a rehearsal won't appear on letsbonk.fun.
Collecting creator fees
The creator share builds up in one vault per creator wallet, shared by all your SOL-quoted LaunchLab coins. Claim it in Creator Fees. A coin on letsbonk.fun's platform adds little or nothing there, because that platform sends its share to BONK burns. To quote a coin against something other than SOL, the StonkFun Launcher runs on the same program.
What you sign
If the logo upload needs a balance, your wallet first approves a small Irys funding transfer. Then one transaction initialises the pool, makes your first buy and pays the 0.05 SOL fee, and if any part fails none of it lands. If letsbonk.fun or Raydium changes its platform config, the simulation fails before anything is signed; launch from the site directly in the meantime.
