Launchpad
Run a presale or a fair launch whose tokens are escrowed up front and whose Raydium listing happens automatically, with the LP burned or locked. Devnet only until audited.
Step by step
- Step 1Connect wallet
- Step 2Set the termsPresale price and caps, or a fair-launch token amount; schedule; optional allowlist; liquidity share; vesting.
- Step 3Escrow the tokensOne transaction moves the sale and liquidity tokens into the program's vault and opens the sale.
- Step 4Contributors deposit SOLInto a program-controlled vault. Refundable in full if the soft cap is missed.
- Step 5ListedAnyone runs the listing: the program creates the Raydium pool and burns or locks the LP; contributors claim on their vesting schedule.
Two sale types
A presale sells at a fixed price up to a hard cap, which ends the sale early when reached. A fair launch has no price: contributors deposit SOL during the window and the tokens for sale are split pro-rata at the end.
What is escrowed
At creation the program takes the tokens for sale plus the tokens needed for liquidity at the hard cap. The mint must have both its mint and freeze authorities revoked, so supply is fixed and nothing can be frozen. Contributed SOL goes to a vault only the program can move.
Allowlists and vesting
An optional allowlist (a CSV of wallets with per-wallet caps) opens an early window or makes the sale whitelist-only; contributors prove membership with a Merkle proof the sale page fetches for them. Vesting — a share at listing, a cliff, then linear release — is enforced on-chain at claim time.
Listing
Once a sale succeeds, anyone can run the listing in three transactions: settle the split, create the Raydium CPMM pool from the escrow, then burn the LP or lock it forever with Raydium's locking program (the creator receives the fee-key NFT). The platform fee and the creator's proceeds are paid in that last step, so a settled sale whose pool can't be created can still refund everyone after seven days.
Fees
Solstack takes a share of the SOL raised (3% by default) at listing. A listing reserve (about 0.22 SOL) covers Raydium's pool fee and rent; whatever it doesn't use is returned to the creator.
FAQ
What does the Launchpad guarantee?
The tokens for sale and for liquidity are escrowed by the program before anyone can contribute; contributed SOL sits in a program-controlled vault the creator cannot touch; and when the sale succeeds, the program itself creates the Raydium pool and burns or permanently locks the LP. The creator only receives their share once the market exists.
Presale or fair launch?
A presale has a fixed price and a hard cap. A fair launch has no price: everyone deposits SOL in the window and the tokens split pro-rata at the end, so the market sets the price.
What if the soft cap is missed?
Anyone can mark the sale failed once it ends, and every contributor refunds themselves in full. The creator gets their escrowed tokens back.
Who creates the pool, and who pays for it?
Anyone can run the listing once the sale succeeds — the program does the work. Raydium's pool-creation fee and rent are set aside from the raise (the listing reserve); the person running it pays only network fees.
Burn LP or lock LP?
Both are irreversible. Burning destroys the LP tokens. Locking uses Raydium's locking program: the LP is locked forever and the creator receives a fee-key NFT that collects the pool's trading fees.
What does Solstack charge?
A share of the SOL raised (3% by default), taken on-chain at listing. Nothing upfront, nothing if the sale fails.
Why devnet only?
The Launchpad is a new, unaudited on-chain program that holds contributors' SOL. It stays on devnet until it has had a security review.
