What Raydium's LaunchLab platform gives a bundled coin
LaunchLab is one program with many platform accounts. This tool uses Raydium's own (the raydium.io default), so the coin appears in Raydium's launchpad listings rather than on letsbonk.fun. Its trading fee is 1.05% per curve trade as of November 2026: 0.25% to Raydium's protocol, 0.75% to the platform and 0.05% to the coin's creator, which accrues in a creator fee vault for your wallet that you can collect with the creator fee claimer.
The curve itself is Raydium's default: 1,000,000,000 tokens, 793.1 million sold for an 85 SOL raise, then migration to a Raydium CPMM pool holding the 85 SOL and the remaining 206.9 million tokens. Coins never need a separate pool setup.
A bundle in numbers
Say you dev-buy 1 SOL and 8 wallets buy 0.5 SOL each. Together they spend 5 SOL and get about 152 million tokens, 15.2% of supply. The 1.05% fee on that is about 0.0525 SOL, of which about 0.0025 SOL is your creator share. Costs on top: SOLTidy's 0.3 SOL, roughly 0.021 SOL of rent and Metaplex's fee for the new accounts, the 0.001 SOL tip, and about 0.0045 SOL per buyer for its token account and network fee.
Jito's 5-transaction limit sets the size. Your transaction carries initialize_v2, the dev buy and the fee. Each LaunchLab buy wraps SOL, trades with buy_exact_in and unwraps, about 262 bytes per wallet, so 2 wallets fill a buyer transaction under the 1,232-byte limit (measured November 2026), and 4 buyer transactions give 8 wallets.
| Order | Who signs | Payload |
|---|---|---|
| 1st | Creator wallet, new mint | Coin creation on Raydium's platform, dev buy, 0.3 SOL fee |
| 2nd to 4th | A pair of buyers | Two wSOL-wrapped buys |
| 5th | A pair of buyers | Two buys and the Jito tip |
Visibility, slippage and your keys
Raydium's launchpad page, Solscan, RugCheck and Bubblemaps all show which wallets bought in the launch block. If those are your team or treasury wallets, say so; using a bundle to fake broad demand misleads buyers and may break market manipulation rules.
Each buy carries a minimum token amount from its in-order quote. If the curve would give less, that buy fails and Jito discards the whole bundle instead of letting it fill worse. The buyer keys sign in this tab and are wiped afterwards; only signed transactions leave the browser, via a SOLTidy forwarder that never sees a key.
Questions & answers
Where does a coin launched here show up?
On Raydium's LaunchLab launchpad at raydium.io, because it is created under Raydium's platform account. Bonk.fun lists only coins made under its own platform.
Do I earn creator fees on the bundled buys?
Yes. Raydium's platform pays the creator 0.05% of every curve trade, the bundle's buys included, into a creator fee vault for your wallet.
Why does a LaunchLab bundle hold 8 buyers?
Each buy wraps SOL and takes about 262 bytes, so 2 fit per transaction, and Jito allows 4 buyer transactions after the create.
Is the dev buy priced exactly?
Yes. The curve is created in the same transaction, so the dev buy runs on known reserves, and each buyer is priced on the reserves the earlier buys leave.
What does a failed bundle cost?
Nothing at all: no coin, buys, tip or 0.3 SOL fee. Retry with the same coin address, or a higher tip if blocks are busy.
