Run a Solana Token Presale

An escrow account owned by Meteora's presale program, which is open source and has been audited by Offside Labs twice and by Sherlock. Not us, and not the creator: the creator cannot touch the raise until the sale has ended above its minimum. Every action a contributor takes, including getting refunded, is an instruction they send straight to that program without going through any server of ours.

The sale is failed and every contributor takes back their entire contribution, from the contribution page, themselves. The creator receives nothing and gets their tokens back. This is the path we test against real devnet on every change, because it is the one nobody exercises until they need it.

Yes, with one caveat worth stating rather than hiding. We never hold contributions and cannot move them: the escrow belongs to a program, not to a wallet. The caveat is that Meteora holds that program's upgrade authority, so it is not frozen code. That is the same situation as the vesting tool, which runs on Jupiter Lock, and it is the trade for not writing and auditing custody software ourselves.

No. The caps, the dates and the vesting are fixed the moment the transaction confirms. You cannot extend it, lower the minimum, or stop it early. Check the numbers before you sign, because afterwards nobody can adjust them, including us.

No, and this is the most important thing on this page. The program does not deploy liquidity. When your sale succeeds you withdraw the raise, and then it is on you to create a pool so the token can actually be bought and sold. A creator who takes contributions and stops there has sold people something they cannot trade.

Prorata means the price depends on how much is raised in total, and the sale is allowed to be oversubscribed: if more comes in than the maximum, everyone is scaled down by the same proportion and the excess is returned. We use it because it is the mode where a contributor can always take their money back before the sale ends. The program also offers first-come-first-served, which refuses withdrawals once deposited, and we do not offer that.

While the sale is running, yes, any amount, at any time. Once it ends the plain withdrawal stops working and settlement takes over: if the sale failed you get everything back, and if it succeeded but was oversubscribed you get back the part that could not be used. The contribution page shows whichever one applies rather than making you guess.

A flat tool fee, paid once by the creator when the sale is made. We do not take a percentage of what your backers contribute. Several platforms take 2.5 percent of funds raised on top of a flat fee; taking a cut of strangers' money is a different kind of business from charging for a tool, and we have not made that choice.

Not through this tool. The program supports whitelists by address and by Merkle proof, but both need the creator to run a server that hands out proofs or signatures, and a tool that depends on a server the creator has to operate is a tool that breaks the day that server goes down. Ours creates permissionless sales, which anyone can contribute to.

The program does. It also refuses a sale longer than 30 days, one scheduled to start more than 30 days out, and a per-buyer maximum of zero. The tool checks all of those before you sign, because otherwise the program rejects the transaction after you have approved it and the only explanation is a hexadecimal error code.
