How Pumpster works

01Overview

Pumpster is not simply a token-creation interface. For selected launches, Pumpster deploys its own SOL, acquires and fully owns a support position, retains creator fees until the relevant repayment target is settled, and applies public vesting and exit rules.

The objective is to support real builders who may not have launch capital, while protecting Pumpster capital, creating clear founder accountability and giving token holders transparent information they can verify on-chain.

Pumpster is not a pump-and-dump product, a price-support promise, an investment product or a guaranteed-return mechanism.

1. 1Anyone can create a launchPay the 0.30 SOL Creation Fee, accept the terms, receive a branded CA.
2. 2Approved launches receive Support CapitalPumpster-owned SOL buys tokens into a Pumpster Support Vault. Never into the creator's wallet.
3. 3Creator fees repay the protocol first100% of eligible creator fees route to the Repayment Vault until the Repayment Target is settled.
4. 4Then the creator is paid95% of every claim to the Creator Fee Wallet, 5% to Pumpster Treasury.
5. 5Everything is publicVaults, vesting schedules, fee routing, support positions and exit rules are verifiable on-chain.

02Core principles

• Pumpster uses Pump.fun as the underlying token-launch infrastructure.
• Anyone can submit or create a launch; only approved launches receive Pumpster Support Capital.
• Tokens acquired with Pumpster Support belong exclusively to Pumpster and are never placed in the creator's wallet.
• Founder allocation, Founder Purchase tokens and the Pumpster Support Position are always separate.
• Founder allocation is subject to public, mandatory vesting.
• Creator fees are retained by Pumpster until the Repayment Target is settled. If the target is not met by the end of Day 31, retention continues until the outstanding balance is fully recovered.
• After full repayment, creator fees are split 95% to the creator and 5% to Pumpster Treasury.
• Every Pumpster Verified Launch must use a branded contract address ending in pster.

03Launch types

Before a Verified Builder Launch, the creator accepts Pumpster's ownership of its Support Position, the creator-fee routing and repayment rules, the Day-31 review and exit policy, the founder vesting requirements, founder wallet disclosure and the branded contract-address requirement.

04Creation Fee

Pumpster Creation Fee: 0.30 SOL
0.30 SOL → Pumpster Treasury / Operations Vault

The fee is paid before the token-creation flow begins and is non-refundable once branded CA generation starts. It is separate from Support Capital, the Support Position, Founder Allocation, Founder Purchase, creator-fee repayment and the post-repayment split. Paying it does not guarantee approval for Support Capital. The fee transaction is shown on the public token page.

It funds product development, frontend, backend, API and database infrastructure, vanity-mint generation, transaction preparation and automation, security monitoring, token pages, dashboards, on-chain analytics and launch-review operations.

05Support Position

Pumpster may provide a Launch Advance in SOL to an approved launch. The capital acquires tokens during the Pump.fun bonding-curve flow. Those tokens go directly to a dedicated Pumpster Support Vault. This is not a dev buy, not a founder allocation and never sent to the creator's wallet.

Pumpster uses fixed SOL support by tier rather than promising a fixed percentage of supply. Before launch it displays the SOL amount, Protocol Fee, Repayment Target, maximum slippage and maximum Support Position as a percentage of initial supply. The token page then displays the SOL actually deployed, the exact token amount acquired and the effective percentage of supply held.

The creator has no ownership, transfer, claim, voting, staking or selling right over the Support Position. It is Pumpster collateral for capital deployed, market volatility and launch risk, and may only be held, gradually sold, locked, burned or otherwise used under the public protocol policy.

06Creator-fee repayment

Repayment Target = Launch Advance × (1 + Protocol Fee)

Launch Advance: 5 SOL
Protocol Fee: 15%
Repayment Target: 5.75 SOL

From launch until the end of Day 31, eligible creator fees route to the Pumpster Repayment Vault. If the target has not been reached by then, Pumpster continues retaining eligible creator fees until the entire outstanding balance is settled.

If Day-31 Repayment Progress < 100%:
    100% of eligible creator fees → Pumpster Repayment Vault
    until the Repayment Target is fully settled

Once settled:
    95% of creator fees → Creator Fee Wallet
    5% of creator fees → Pumpster Treasury

The 5% Treasury share may fund operations, security, launch-support reserves, builder grants, buyback or burn initiatives or other disclosed treasury policies. It is never communicated as a guaranteed return to token holders.

07Founder vesting

Example: a 30% founder allocation needs at least 20 monthly unlock periods after the cliff. All founder-controlled wallets are declared before launch and cannot be changed or supplemented secretly. Mint and other authorities are disclosed and, where required, revoked. Hidden minting, honeypots, mutable hidden taxes, abusive transfer controls and hidden blacklists are prohibited. Vesting cancellation exists only for pre-disclosed fraud or material-breach cases.

08Founder Purchase

After Pumpster executes its support purchase, the creator may optionally buy a limited position directly from Pumpster: up to 2.00% of initial supply across all Founder Purchase transactions combined. Inventory sits in a separate Founder Purchase Reserve Vault, never mixed with Support collateral.

Founder Purchase Price = Allocated Pumpster Cost Basis + 10% Founder Purchase Fee + Direct Execution Costs
Minimum Transfer Price  = Allocated Cost Basis × 1.10 + Direct Execution Costs

Reserved amount: 1.00% of supply
Allocated cost basis: 2.00 SOL   Fee 10%: 0.20 SOL   Execution: 0.01 SOL
Total founder payment: 2.21 SOL

An unpaid or partially paid optional reservation would give the creator a free option while Pumpster bears the downside, so it is not offered.

09Day-31 review and exit

For the first 31 days Pumpster holds its Support Position and does not sell, except in a Security Exit caused by fraud, a rug attempt, an exploit or material security incident, undisclosed supply or minting, a hidden founder-controlled wallet, a vesting bypass attempt or a material breach of launch terms.

Example Builder Launch criteria
Day-31 repayment threshold: 25% of Repayment Target
Minimum cumulative volume: configured by tier
Minimum builder updates: 4 during the first 31 days
Security compliance: mandatory

Maximum Daily Sell = min(0.25% of initial total supply, 5% of rolling 24-hour volume)

• Maximum daily sale configurable between 0.25% and 0.50% of initial supply.
• Maximum trade size based on current liquidity and volume; maximum slippage 2%–5%.
• Automatic pause below defined liquidity and volume thresholds.
• Every sale publicly recorded: token amount, execution price, SOL recovered, remaining Support Vault balance.
• No full-market dump, no undisclosed manual sale, founder-locked tokens never sold in a performance exit.
• Creator-fee retention continues while a repayment balance is outstanding, even during an orderly exit.

10Branded contract address

Every Pumpster Verified Launch uses a token mint address ending exactly in pster. Tokens without the suffix cannot be displayed as Verified Launches or receive Support Capital, except under a disclosed exceptional policy.

8xK...mYpster
3Fn...Qrpster
A7v...4Lpster

58^5 = 656,356,768 average candidate keypairs

1. 1GenerateA dedicated, ideally GPU-accelerated worker generates candidate keypairs until the public key ends in pster.
2. 2ValidateThe suffix is verified before the launch transaction is prepared. A Verified Launch never proceeds without it.
3. 3Sign onceThe keypair signs the creation transaction through a Pump.fun flow that accepts a custom mint signer.
4. 4DestroyTemporary private-key material lives only in protected volatile memory and is destroyed when no longer required. It never touches frontend code, repositories, logs, analytics, databases or error tracking.
5. 5ConstrainMint and other authorities are revoked or constrained after creation under the Pumpster safety policy.

11Vault architecture

Pumpster Treasury Multisig
│
├── Pumpster Treasury Vault
├── Pumpster Repayment Vault
├── Token A — Pumpster Support Vault
├── Token A — Founder Purchase Reserve Vault
├── Token A — Founder Vesting Vault
└── One isolated vault set per supported token

• Treasury and Support Vault controls use a multisig, never a hot wallet: 2-of-3 initially, 3-of-5 for larger treasuries.
• Every supported token has a separate Support Vault and Founder Purchase Reserve Vault.
• Public vault addresses and explorer links appear on every token page.
• Sensitive treasury movements use approval rules and timelocks where feasible.

12Public token page

Route: /launchpad/[token-address]. Each page shows the token hero with branded CA and market data, the status badge, the Creation Fee card, the Pumpster Support card, the Repayment card, the Creator Fees card, Founder Vesting, Founder Purchase, the Vanity CA card, Security & Disclosure, Builder Activity and the Day-31 Review & Exit card. Browse launches.
