Overview
How it works
A presale pad for pump.fun launches. Pool SOL up front, launch the coin bonded, and get your tokens back automatically — or get refunded if it never fills.
- 01
A dev creates a listing
Name, ticker, image and pitch. The pad immediately generates a fresh escrow wallet that exists only for this one presale. Nothing is minted yet — there is no token until the raise fills.
- 02
Backers send SOL to that vault
Connect a wallet and contribute, or send manually to the vault address. Every deposit is credited to the wallet it came from, which is the address your tokens will be returned to. The vault address is on the listing page and every movement is public on-chain.
- 03
The target fills and the coin launches
Once the vault reaches 86.31 SOL, the pad mints the token on pump.fun and buys out the entire bonding curve in a single atomic transaction. Because the buy clears the curve, the coin graduates the instant it is created.
- 04
Tokens go back to the wallets that paid
The vault splits its token balance pro-rata by SOL contributed and sends each backer their share, to the exact address they sent from. Allocations are frozen before the first transfer, so a late deposit cannot change anyone else’s share.
- 05
Or everyone gets refunded
If the target is not reached by the deadline, every contribution is returned to its source wallet, less network fees. The same happens if a launch fails before any token is minted.
What it takes to bond a token
“85 SOL” is the number everyone repeats, and it is wrong. It buys 99.738% of the curve and the coin never graduates. Here is the actual arithmetic.
| Curve tokens for sale | 793,100,000 |
| Cost to buy all of them | 85.005 SOL |
| pump.fun trade fee (1%) | +0.850 SOL |
| Clears the curve | 85.855 SOL |
| Creator fee (0.3%), account rents & gas | +0.450 SOL |
| Every presale target | 86.31 SOL |
The target is identical for every listing and cannot be set by the dev. Below 85.86 SOL the coin cannot graduate; above it, the extra just overpays the curve. There is nothing useful to tune, so the pad does not pretend otherwise.
The token account deposit
Solana charges rent to create the account that holds your tokens — about 0.00205 SOL per backer. The pad takes that out of your contribution rather than out of the raise.
That is deliberate. If the rent came out of the pooled SOL, a presale filled by many small backers would quietly spend its curve budget on account rent and stop bonding. Charging each backer for their own account keeps the amount reaching the curve fixed at 86.31 SOL whether ten people back it or a thousand.
How your allocation is calculated
Pro-rata by accepted SOL. If you put in 2 SOL of an 86.31 SOL raise, you receive 2 / 86.31 of the tokens the vault bought — roughly 2.3% of the curve supply. Shares are rounded down to whole token units; the few leftover units stay in the vault rather than risking a transfer larger than the balance.
Caps and over-subscription
Each listing sets a maximum per wallet. If your deposit would push the raise past its target, only the part that fits is accepted and the remainder is refunded to you — in the same transaction that pays out your tokens. Deposits below the 0.05 SOL minimum are not counted and are returned.
Never contribute from an exchange
Tokens and refunds go back to the address the SOL came from. A withdrawal from an exchange arrives from a hot wallet you do not control, and an exchange deposit address cannot receive an arbitrary SPL token. The pad detects deposits it cannot safely attribute and flags them for manual review rather than guessing, but the only reliable fix is to send from your own wallet.
What can go wrong
- The raise never fills. Everyone is refunded at the deadline, less network fees. This is the ordinary outcome for most listings.
- The coin goes to zero after it bonds. Backers are the entire initial float, bought at the top of the curve. If everyone sells into the migration it collapses within minutes. This is common.
- The operator is dishonest. Escrow vaults are controlled by this site. Deterministic addresses, public vaults and on-chain proof of every payout make misuse visible; they do not make it impossible. Only rules enforced on-chain could do that.
- Per-wallet caps are not sybil resistance. One person with ten wallets is ten wallets.
