PREUP Docs
Everything you need to know about the PREUP presale platform.
Introduction
PREUP is a decentralized token presale platform on Solana. Anyone can create a presale, collect SOL from the community, and once the presale ends the token is listed on Pump.fun — fully on-chain, fully transparent.
Creators choose between two modes: HardCap (presale ends when a set SOL amount is reached, 1–85 SOL) or Time Based (presale ends at a specific date/time, max 85 SOL).
After listing, contributors claim tokens proportional to their share. No middlemen, no trust assumptions — everything is handled by the on-chain program.
How It Works
Create a presale
Fill in the token name, symbol, image and social links. Choose HardCap or Time Based mode. Creating is free.
Community buys in
Anyone can contribute SOL. A 0.5% fee is taken from every contribution and sent to the PREUP treasury. The rest goes into the presale vault.
Listing
In HardCap mode, listing triggers once the hardcap is reached. In Time Based mode, listing happens after the timer expires. The program creates the token on Pump.fun and buys tokens with all collected SOL.
Fee sharing
Right after listing, the creator clicks Get Fees in their Profile. This sets up fee sharing so 98% of Pump.fun volume fees go to the creator.
Claim tokens
After listing, contributors claim their tokens. Your share is proportional to your SOL contribution.
Presale Modes
- SOL target from 1 to 85 SOL
- Ends when hardcap is reached
- If never reached — token won't list
- Set end date & time (min 5 min)
- Max cap fixed at 85 SOL
- If 85 SOL hit early — lists immediately
Fees
PREUP fee on every buy. 1 SOL in = 0.005 SOL fee + 0.995 SOL to vault.
Pump.fun fee when the program buys tokens at listing.
Of Pump.fun volume fees go to the token creator after activating Get Fees.
Click Get Fees in Profile as soon as possible after listing. Until activated, volume fees are not directed to the creator.
Smart Contract
PREUP runs on a verified Solana program. All logic — contributions, fees, listing on Pump.fun, and token claims — is handled entirely on-chain.

Formulas
User token share
Tokens bought at listing
sol_in = total_sol * 0.995 * 0.99 - 0.006
total_tokens = (sol_in * 1,073,000,000) / (30 + sol_in)
Price per token
Examples
HardCap — 85 SOL
sol_in ≈ 83 SOL

price ≈ 0.000000108 SOL
HardCap — 10 SOL
sol_in ≈ 9.4 SOL
tokens ≈ 255,776,709
price ≈ 0.0000000391 SOL
TimeBased — 42 SOL collected
sol_in ≈ 39.5 SOL
tokens ≈ 609,712,230
price ≈ 0.0000000689 SOL
Token Distribution
Based on 85 SOL HardCap presale (~788M tokens purchased).
| Contribution | Share | Tokens |
|---|---|---|
| 1 SOL | 1.18% | ~9.2M |
| 10 SOL | 11.76% | ~91.8M |
| 85 SOL | 100% | ~780M |
