How a curve sale is built
While the coin bonds, every sale is put together from LaunchLab's account layouts: open a temporary wSOL account, sell_exact_in the token amount with a minimum SOL out, close the wSOL account so the SOL lands unwrapped, optionally close the emptied token account, then transfer SOLTidy's fee from the proceeds.
Sales push the price down for the next wallet, so the review replays them in order on a copy of the reserves and each wallet re-reads the pool before it sells.
Which fee applies
The platform decides. A coin from Raydium's own LaunchLab platform pays 1.05% of the SOL a sale returns as of November 2026, 0.05% of it to the creator; a Bonk.fun coin pays 1.5%. SOLTidy's 0.5% is measured on the slippage floor and stops at 0.1 SOL for the whole run.
Example: selling 10 million tokens into a curve holding 30 SOL returns about 1.075 SOL after the 1.05% fee. At 5% slippage the floor is about 1.021 SOL and SOLTidy takes about 0.005 SOL. A run of 40 such wallets would be about 0.2 SOL at 0.5%; it is capped at 0.1 SOL.
| Item | SOL |
|---|---|
| Floor per sale at 5% slippage | ≈ 1.021 |
| 0.5% of all floors | ≈ 0.2 |
| SOLTidy fee charged (per-run cap) | 0.1 |
Selling after migration
Once the 85 SOL target is met, the coin trades in a Raydium CPMM pool (AMM v4 for older configs). Sales then go through Jupiter with only that program allowed, and the wSOL is unwrapped in the same transaction. A run that straddles migration switches over without you doing anything.
Reading a LaunchLab coin before you sell
The panel shows the curve's progress toward 85 SOL as you load the coin. A coin at 20% has little SOL in the curve, so even a modest exit from a dozen wallets can take a large bite of the price; a coin at 90% is close to migrating, and selling then pushes it further from the target instead of letting it graduate into its Raydium pool. Selling a share of each wallet rather than everything is a common way to take some SOL off the table while the curve keeps building.
The creator share on Raydium's own platform is small (0.05%), so most of the curve fee goes to Raydium and the platform. Other LaunchLab platforms set their own splits; the tool shows the coin's platform by name so you know whose fee table applies.
Questions & answers
What does it cost to mass sell a LaunchLab coin?
The platform's curve fee out of the proceeds plus SOLTidy's 0.5% of each sale's minimum SOL out, capped at 0.1 SOL per run.
Do wallets need SOL to sell?
Only for the network fee and, briefly, the wSOL account's rent, which comes back in the same transaction.
Is the payout native SOL?
Yes, the temporary wSOL account is closed in the same transaction.
Can I sell coins from any LaunchLab site?
Yes, as long as the curve is quoted in SOL. The platform is shown when the coin loads.
Can sales land in one block?
Yes. Same-block mode packs as many curve sales into each transaction as fit, in Jito bundles of up to five transactions.
