White Paper

Pixpel Launchpad: A Decentralized Game Funding Platform

Version 1.0 | Date: September 15, 2025 | Prepared by: Pixpel Team

Abstract

The decentralized finance (DeFi) ecosystem has grown rapidly, but token launch mechanisms remain fragmented, opaque, and investor unfriendly. Pixpel Launchpad introduces a comprehensive, mathematically driven solution using a modular four contract architecture: a Launchpad Contract for fundraising, a Vesting Contract for automated distribution, an LP Fund Manager for liquidity creation and control, and a revolutionary Scam Manager for community driven anti fraud protection. The platform’s core innovation lies in its automated liquidity system, allocating 50 percent of raised funds to decentralized exchanges and distributing LP tokens via differentiated vesting schedules: 12 months for developers (3 cycles × 4 months) and 3 months for investors (3 cycles × 1 month). Investor protection is prioritized through features like investment caps (max 30 percent of total supply), soft cap thresholds, automatic refunds for failed launches, cliffbased vesting, and a pioneering community driven scam detection system. The Scam Manager enables post launch fraud protection through a democratic voting mechanism, allowing investors to flag malicious projects and recover intercepted funds through proportional redistribution. Multi-chain compatibility is ensured through chain agnostic smart contracts, optimized to deliver gas efficient operations. Support for both native token and token-token liquidity pairs allows flexible deployment across ecosystems. Registration fees differ by network: 500 PIXP tokens on restricted chains (e.g., SKALE) and 0.1 ETH on other chains, with a standardized 5 percent platform fee

1. Introduction

Decentralized finance (DeFi) has grown rapidly, with token launches enabling blockchain projects to raise capital and engage users. However, existing launchpads often lack transparency, investor safeguards, efficient liquidity provisioning, and post launch fraud protection. Pixpel Launchpad addresses these issues with a decentralized, modular platform automating fundraising, token distribution, liquidity creation, and community driven anti fraud mechanisms. Supporting both native-token and token-token campaigns, it ensures flexibility and investor protections through vesting, soft cap enforcement, refunds, and a revolutionary post launch scam detection system. Optimized and compatible with EVM chains, this white-paper outlines the platform's architecture and mechanics, including the industry's first community governed fraud protection mechanism.

02. System Architecture

Pixpel Launchpad consists of three smart contracts designed for seamless operation.

A. Pixpel Launchpad Contract

Purpose:Primary interface for token sales and project management.
Features:Sale creation, investment handling, status management.
Upgradability:Uses UUPS proxy pattern.
Upgradability: Includes Reentrancy Guard and access controls.

B. Pixpel Vesting Contract

Purpose:Manages token vesting and distribution.
Features:Configurable cliff periods, cyclic releases, holder management.
Distribution:Automated per predefined schedules.
Flexibility: Customizable vesting parameters per launchpad.

C. Pixpel LP Fund Manager

Purpose:Handles liquidity pool creation and token distribution.
Features:Automated DEX integration, LP token vesting.
Distribution:50% to developers (4-month cycles), 50% to investors (1-month cycles).
Flexibility: Pixpel Swap compatible router integration.

D. Pixpel Scam Manager

Purpose:Community driven anti-fraud protection and fund recovery system.
Features:Democratic voting mechanism, fund interception, proportional redistribution.
Security:60% threshold requirement with 45-day cooling period.
Recovery Mechanism: Fund and LP token seizure with investor redistribution
Integration: Seamlessly connects with all other platform contracts.

E. Key Calculations

This subsection outlines the mathematical formulas governing the platform's operations.

1. Token Amount Calculation

LP Token Redistribution: T = ( V x 10^18 ) / P (1) where: • T: Token amount received. • V: Invested amount (in native currency or ERC-20 tokens). • P: Token price (in wei or token units).

2. Vesting Cycle Distribution

The vesting contract distributes tokens over N cycles, each releasing a fraction of the total tokens. The number of cycles is: N=[Dv+29] / 30 (2) where: Dv is the vesting duration in days. The percentage released per cycle is: Rc=100 / N (3) The tokens released per cycle for a holder with total claimable tokens C is: Tc=(C×Rc) / 100 (4)

3. Voting Threshold Calculation

The Scam Manager uses a democratic voting system with mathematical precision. Vote Percentage Calculation: V P = ( Yv / Ev ) × 100 (5) where: • V P : Voting Percentage achieved. • Yv : Total votes cast. • Ev : Total eligible voters (all investors in the launchpad).

Proportional Refund Calculation: Rf = ( la x lf ) / Ta (6) where: • Rf : Individual refund amount. • Ia : Individual investment amount. • If : Total intercepted funds. • Ta Total invested amount across all investors.

LP Token Redistribution: LPr = ( ULP x ILP ) / TLP (7) where: • LPr : Individual’s redistributed LP tokens. • ULP : User’s original LP token allocation. • If : Total intercepted LP tokens. • TLP : Total investor LP tokens (excluding developer portion).

03. Roles and Participants

The platform defines three roles:

Administrator: Manages configuration, approvals, and upgrades.
Project Creators (Developers): Initiate a launchpad, supply tokens, and receive raised funds.
Investors (Players): Contribute native currency or ERC-20 tokens, receiving game tokens and liquidity pool shares.
Community Voters: Eligible investors who can participate in fraud detection voting after project completion.

04. System Initialization and Configuration

A. System Initialization

The administrator initializes the platform by connecting the Launchpad Contract to the Liquidity Pool Fund Manager, DEX router, and Vesting Contract. Registration fees vary based on the network configuration, such as 500 PIXP tokens on restricted networks or 0.1 ETH on unrestricted ones. Key parameters including a 5% platform fee are configured during deployment.

B. Fee Management

The Pixpel Launchpad allows the administrator to adjust both the platform fee (initially 5%, modifiable between 0-100%) and the registration fee, depending on the network. On restricted networks like SKALE, the registration fee is set in PIXP; on other EVM chains, it's set in native tokens (e.g., ETH, MATIC). All adjustments are on-chain and admin-controlled, ensuring flexibility and transparency.

The platform fee (Fp) is adjustable (0-100%): Fp = Platform Fee Percentage / 100 (8)

C. Ownership Transfer

The administrator can transfer ownership to a new address, logged on-chain for accountability.

05. Creating a Rocket

A. Preparing Launchpad Configuration

Creators (Developers) specify:

Metadata: Rocket name and URL.
Token : Address, allocation, price.
Constraints: Minimum/maximum contributions (max 30% of supply).
Goals: Soft cap, hard cap (hard cap ≥ 40% above soft cap).
Vesting (Player): Minimum 7-day cliff, non-zero duration.
Liquidity: 30-60% of raised funds.
Pair: Native-token or token-token.
Project Owner Vesting Duration: Enter 0 to disable vesting on fund withdrawals. Otherwise, specify a vesting period of at least 90 days.

B. Granting Token Access

Creators (Developers) authorize token transfers via ERC-20 approval, including a 5% platform fee reserve. TI = Ta+(Ta x Fp) / (1 - Fp) (9) where: • Tl is tokens to lock • Ta is token allocation

C. Registering and Submitting

Creators submit parameters and pay the registration fee. The platform validates inputs, locks tokens, assigns a launchpad ID, and sets the launchpad to Review state.

D. Developer Vesting Incentive Structure

The platform promotes responsible fund management through a vesting incentive system that balances the interests of developers, investors, and the platform itself. Developers benefit from reduced platform fees (5% instead of 10%), gain investor confidence by committing to scheduled fund releases, and build credibility through long-term dedication. At the same time, investors are protected by a 5% fee that supports platform security and operations, enforces developer accountability, and encourages only serious projects to participate through enhanced due diligence.

Vesting Option	Developer Platform Fee	Investor Additional Fee	Total Platform Revenue
With Vesting	5% of raised funds	5% of investment	Optimized
	10% of raised funds	Standard	0%

TABLE I Fee Structure Comparison

06. Launchpad Review and Approval

A. Launchpad Approval Process

Administrators review launchpads. On approval:

Registration fee transfers to the administrator.
5% of tokens are allocated as a platform fee.
Remaining tokens move to the Vesting Contract.
Launchpad status updates to Live.

Tv = Ta × ( 1 − Fp ) (10) where Tv is tokens transferred to Vesting Contract.

B. Launchpad Rejection Process

On rejection:

Tokens and registration fee are refunded.
Launchpad is marked Rejected.

07. Participating in a Launchpad

A. Exploring Available Launchpads

Investors view Live launchpads, including launchpad ID, token price, contribution limits, hard cap, and end time.

B. Contributing with Native Currency

For native currency-token launchpads, contributions are validated, tokens allocated to vesting.

When Developer Vesting is Enabled:

Effective Investment = Investment Amount × 0.95 (11) Platform Fee = Investment Amount × 0.05 (immediately transferred to admin) (12) Token Amount Received = (Effective Investment × 10^18) / Token Price (13)

When Developer Vesting is Disabled:

Effective Investment = Investment Amount (14) Platform Fee = 0% (paid by developer at 10% rate) (15) Token Amount Received = (Investment Amount × 10^18) / Token Price (16)

C. Contributing with ERC-20 Tokens

For token-token launchpads, investors approve token transfers, contributions are validated, tokens allocated for vesting.

When Developer Vesting is Enabled:

Effective Investment = Investment Amount x 0.95 (17) Platform Fee = Token Amount × 0.05 (immediately transferred to admin) (18) Game Tokens Received = (Effective Investment × 10^secondTokenDecimals) / Token Price (19)

When Developer Vesting is Disabled:

Effective Investment = Investment Amount (20) Platform Fee = 0% (paid by developer at 10% rate) (21) Game Tokens Received = (Token Amount × 10^secondTokenDecimals) / Token Price (22)

08. Managing Launchpad Status

A. Pausing a Launchpad

Launchpads below soft cap can be paused (up to 3 times) with a 12-hour gap.

B. Resuming a Launchpad

Paused launchpads resume after 12 hours, re-enabling contributions.

09. Fund Withdrawal

On campaign completion:

5% administrative fee deducted from the total funds raised.
50% of liquidity percentage is reserved for DEX pools.
The remaining funds are transferred to the creator if no vesting duration is selected. Otherwise, the funds will be released according to the 30-day vesting cycles of the chosen duration.
Investor tokens are deducted for liquidity.
LP tokens split: 50% to creators (4-month cycles), 50% to investors (1-month cycles).
Launchpad status updates to Completed.

LP tokens are split: Ld= Lt / 2 , Li=Lt / 2 (23) Calculating individual players LP tokens: Pi(lpt) = Td / Tlp (24) Total claimable LP tokens per player: Clp = Pi(lpt) × T(P)lp (25) LP tokens distribution per cycle: Lpc = Clp / Nc (26) Developer LP tokens per cycle (3 cycles): Ldc = Ld / 3 (27)

where: • Pi(lpt): Individual player LP tokens percentage. • Td: Tokens deducted from an individual player. • Tlp: Total tokens of players added to the LP. • Clp: Claimable LP tokens for investor. • T(P)lp: Total LP tokens for all players. • Lpc: LP tokens per cycle. • Nc: Number of cycles. • Ld: Developer LP tokens. • Li: Investor LP tokens. • Ldc: Claimable LP tokens per cycle for developer.

10. Claiming Locked Tokens

A. Viewing Vesting Information

Investors view cycles completed, claimable tokens, investment amount, and vesting start date.

B. Token Claim Process

After the cliff period, tokens are claimed in 30-day cycles, transferred, and logged via a Tokens Claimed event.

11. Claiming Liquidity Tokens

A. Viewing Liquidity Token Allocation

Participants view allocation, contribution, deducted tokens, and cycle progress.

B. Liquidity Token Claim Process

Creators claim LP tokens over 4-month cycles, investors over 1-month cycles, processed like token vesting.

12. Launchpad Cancellation and Refunds

If a launchpad fails to meet its soft cap:

Tokens return to the creator.
Contributions are refunded.
Launchpad status updates to Cancelled.

13. Anti-Fraud Protection System

The Pixpel Launchpad introduces an industry first community driven anti fraud protection system through the Scam Manager contract, providing comprehensive post launch investor protection.

A. Community Voting Mechanism

1. Eligibility and Timing

Voter Eligibility: Only investors who contributed to a specific launchpad can vote on that project's legitimacy.
Voting Window: Initiate a launchpad, supply tokens, and receive raised funds.
Democratic Process: Transparent, on-chain voting with immutable records.

2. Voting Process

Activation: Voting becomes available 45 days post completion.
Participation: Each eligible investor casts one vote per launchpad.
Threshold: 60% of eligible voters must vote ”yes” to flag a project as fraudulent.
Transparency: All votes and voter addresses are publicly recorded on-chain.

3. Mathematical Validation

The system continuously calculates the voting percentage: Current Percentage = ( Yes Votes / Total Eligible Voters ) x 100 (28) When this percentage reaches or exceeds 60%, the project is automatically flagged as fraudulent.

B. Fund Interception and Recovery

1. Admin Initiated Fund Seizure

Upon reaching the 60% voting threshold, the Scam Manager under the supervision of admin will:

2. Recovery Mechanisms

Vesting Integration: Interfaces with the Vesting Contract to intercept unvested developer funds.
LP Manager Integration: Coordinates with LP Fund Manager to seize developer LP allocations.
Multi-Asset Support: Handles both native tokens (ETH, MATIC) and ERC-20 tokens.

C. Redistribution Process

1. Proportional Fund Distribution

Intercepted funds are redistributed to affected investors based on their original investment proportions:

2. Individual Refund Calculation:

Refund Amount = ( Individual Investment / Total Raised ) / Intercepted Funds (29)

3. LP Token Redistribution

Seized LP tokens are redistributed based on original LP token allocations:

LP Distribution = ( User LP Tokens / Total Investor LP ) / Seized LP Tokens (30)

5. Claiming Process

Verification: System verifies investor eligibility and claim status.
Calculation: Automatically calculates proportional refund amounts.
Distribution: Secure transfer of funds and LP tokens to investor wallets.
Prevention: One time claiming prevents double spending attacks.

D. Security and Safeguards

Vote Integrity

One Vote Per Investor: Each eligible wallet can cast only one vote per launchpad
Immutable Records: All voting data is permanently stored on-chain
Sybil Resistance: Only actual investors (not arbitrary addresses) can participate

Fund Security

Automated Seizure: Reduces human intervention and potential manipulation
Multi-Signature Integration: Critical operations require admin oversight
Emergency Protocols: Safeguards against system abuse or technical failures

Transparent Governance

Public Voting Records: All community members can verify voting results
Clear Thresholds: 60% requirement prevents minority manipulation
Time-Locked Activation: 45-day delay allows legitimate projects to establish themselves

14. Centralized Aspects

A. Pause and Resume Powers

Administrators and creators can pause/resume campaigns, controlling investor access.

B. Fund Withdrawal Control

Administrators or creators withdraw funds, with administrators holding override privileges.

C. Vesting and Liquidity Token Distribution

Administrator-owned contracts manage vesting and LP distribution, introducing indirect centralization.

D. Campaign Cancellation

Administrators and creators can cancel campaigns, with administrators holding override powers.

15. Additional Tools

Users can:
