What LaunchLab creates

LaunchLab is Raydium's bonding-curve launchpad program. This tool calls its initialize_v2 instruction with Raydium's own platform account (the default on raydium.io) and the SOL constant-product config. The program creates a standard SPL token with 6 decimals and 1,000,000,000 supply, its Metaplex metadata, and a curve that sells 793.1 million tokens until 85 SOL has been raised. It keeps no mint or freeze authority.

When the curve fills, Raydium migrates the coin to a CPMM pool with the 85 SOL and the remaining 206.9 million tokens. Your dev buy, if you set one, runs in the same transaction on the brand-new curve with buy_exact_in, so it gets the first and cheapest tokens and can't be front-run.

LaunchLab's fees, and the creator share

LaunchLab charges nothing to create a coin. You pay about 0.021 SOL: rent for the mint, metadata, pool and vaults and Metaplex's 0.01 SOL metadata fee. Every curve trade, your dev buy included, pays 1.05% as of November 2026: Raydium's 0.25% protocol fee, the platform's 0.75% and 0.05% to the coin's creator. That creator share accrues to a fee vault for your wallet and is claimable from Raydium. SOLTidy adds a flat 0.1 SOL in the create transaction.

Example: a 1 SOL dev buy on a fresh curve gets about 34.3 million tokens, 3.43% of the supply, and the launch costs about 1.12 SOL in total (1 SOL buy, 0.1 SOL to SOLTidy, about 0.021 SOL of rent and fees). About 85.9 SOL would buy the whole curve and migrate the coin at once.

Dev buys on a fresh LaunchLab curve (1.05% fee included, November 2026)
Dev buy	Tokens	Share of supply
0.5 SOL	≈ 17.4 million	≈ 1.74%
1 SOL	≈ 34.3 million	≈ 3.43%
5 SOL	≈ 152 million	≈ 15.2%

LaunchLab, Bonk.fun or your own pool

Bonk.fun runs on the same LaunchLab program and curve, under its own platform account with a 1.5% trading fee and its own listing on letsbonk.fun; use the Bonk.fun launcher for that. If you'd rather set your own supply and price from the first second, create a Raydium CPMM pool directly with the Raydium launcher. To buy from several wallets in the launch block, use the LaunchLab bundle launcher.

Questions & answers

Where does my coin appear?

It is created under Raydium's LaunchLab platform account, the one raydium.io uses, so Raydium's launchpad pages and launch listings attribute it to Raydium.

Can I change the supply, curve or target?

No. The tool uses Raydium's default LaunchLab settings: 1,000,000,000 tokens, 793.1 million sold on the curve and an 85 SOL target, migrating to CPMM.

Do I earn anything as the creator?

Yes. Raydium's LaunchLab platform gives the creator 0.05% of every curve trade, paid into a creator fee vault for your wallet.

Why buy in the same transaction?

So nobody buys before you. A dev buy inside the create transaction runs on the fresh curve before anyone else can trade it.

Is this non-custodial?

Yes. The mint key is generated in your browser, you sign in your own wallet, and the coin and tokens are yours.

Is there a fee?

A LaunchLab launch costs SOLTidy's flat 0.1 SOL, paid in the same transaction. LaunchLab charges no create fee; the new accounts take about 0.021 SOL of rent and Metaplex's metadata fee, and your dev buy pays LaunchLab's 1.05% trading fee.
