PrePump

Create a presale, collect SOL, auto-list on @Pumpfun
HardCap or Time-Based. Fully on-chain.

Vamping & griefing are some of the biggest pain points of recent times

Although it's impossible to solve 100% of this behavior at the blockchain layer, we can still try to mitigate where we can

Today’s update is a small step in that direction. Here’s how it works 👇

[PrePump @PresalePump]

PrePump compresses the entire token launch process into a single flow:

Create → Fund → List → Claim

All enforced by code.

[PrePump @PresalePump]

PrePump is not just a presale tool.

It’s a fully on-chain system that handles the entire lifecycle of a token launch.

Here’s what the product actually does:

[PrePump @PresalePump]

Fully on-chain execution

Everything is handled by the program:

• contributions
• fee logic
• listing trigger
• token purchase
• claims
No off-chain dependencies.

If you’re experimenting with token launches on Solana:

PrePump is built exactly for that.

Create a presale in minutes.

Let the community decide how much capital the launch receives.

[PrePump @PresalePump]

PrePump started with a simple idea:
Presales should not require trust.

Now anyone can:
• Create a presale
• Raise SOL from the community
• Automatically list on https://t.co/qBZxzzRqiK
• Distribute tokens fairly
All executed by smart contracts.

More updates coming soon.

What makes PrePump different?

• Fully on-chain presales
• Automatic https://t.co/qBZxzzRqiK listing
• Proportional token distribution
• HardCap or Time-Based modes
• No custody of user funds

Presales should be predictable.
That’s what PrePump is built for.

[PrePump @PresalePump]

We’re already seeing the first presales launching on PrePump.

Huge thanks to everyone who decided to try the platform early and trusted the protocol for their launches.

We’re also starting to receive the first real user feedback which is incredibly valuable.

Early builders and contributors help shape the product.

Thank you for testing, launching, and sharing your thoughts. More improvements coming soon.

PrePump has two types of fees.

During presale

0.5% — PrePump protocol fee
~1% — https://t.co/S5MgeOAVgw trading fee
~0.006 SOL — Solana rent reserve
After listing
Trading volume generates https://t.co/S5MgeOAVgw fees.

98% → token creator
2% → PrePump

Creators receive the majority of trading fees generated by their token.

[PrePump @PresalePump]

What determines the launch price of a PrePump token?

Two variables:

• Total SOL collected
• https://t.co/S5MgeOAVgw bonding curve
The contract buys tokens using the collected SOL.

The price per token becomes:

price = total_SOL / total_tokens

More SOL → higher initial market cap.
Less SOL → smaller supply bought → lower market cap.

Everything is deterministic.

[PrePump @PresalePump]

PrePump uses a straightforward, math-based approach to allocate tokens.

The more you contribute, the larger your share of tokens will be.

Here’s how it works:

user_tokens = (user_SOL / total_SOL) × total_tokens

For example:

If you put in 10% of the total pool,
you’ll get 10% of the tokens bought on @Pumpfun

There are no tiers.
There are no whitelist advantages.
There are no hidden allocations.

[PrePump @PresalePump]

For example:

A presale collects 42 SOL in Time-Based mode.

After deducting fees and rent,
≈ 39.5 SOL goes into buying tokens.
The contract then purchases tokens on https://t.co/S5MgeOAVgw.

If you contributed 4.2 SOL, which is 10% of the pool, you will receive 10% of the total tokens purchased.

There is no negotiation involved.
No whitelist advantage is provided.
Allocation is strictly proportional.

[PrePump @PresalePump]

HardCap mode offers a straightforward process.

The creator sets a funding target between 1 and 85 SOL.
The presale ends once the target is reached.
Listing occurs immediately after the target is met.
If the hardcap is not reached,
no listing will take place.

The target is clearly defined.
The outcome is transparent.
There is no ambiguity in the process.

[PrePump @PresalePump]

Time-Based mode introduces a fixed deadline.

The creator selects an end date, which must be at least five minutes in the future.
The maximum cap is 85 SOL.
The presale ends when the timer expires.

If 85 SOL is reached early:
listing occurs immediately.

Participation remains dynamic throughout the presale.
Predictable timing.
