Overview of Reward System
JustPump distributes rewards to community members through a secure, user-initiated claim system. Rewards come from various sources including:- Airdrop Fund: 0.2% of JustSwap trades go to community airdrops
- Cashback Vault: Insurance fund for failed projects (see Cashback Vault)
- Special Promotions: Platform-sponsored campaigns and events
All rewards use the same underlying mechanism: signed vouchers that you submit on-chain to claim your funds.
How Reward Claims Work
The reward system uses signed vouchers to enable secure, verifiable claims without complex on-chain logic.1
User Becomes Eligible
Based on your activity (trading volume, participation, specific events), you become eligible for rewards during distribution windows.
2
Backend Calculates Amount
The JustPump backend analyzes on-chain data and calculates your claimable amount based on eligibility criteria.
3
Backend Issues Signed Voucher
A cryptographically signed voucher is generated containing:
- Your wallet address
- Reward amount (in SOL)
- Expiration timestamp
- Unique identifier (prevents replay)
- Digital signature from authorized backend key
4
User Submits Voucher On-Chain
You visit JustPump and submit the voucher. The smart contract verifies:
- Signature is valid (matches authorized public key)
- Voucher hasn’t expired
- Voucher hasn’t been claimed before
- Recipient matches your connected wallet
5
Vault Transfers SOL
Upon successful verification, the vault immediately transfers SOL to your wallet in the same transaction.
Design Principles
User Pays Gas
You pay the small transaction fee to submit your claim. This approach:- Prevents spam claims (users must intentionally claim)
- Reduces platform costs (no automatic distributions)
- Gives you control over timing (claim when convenient)
Gas costs on Solana are extremely low—usually fractions of a cent per transaction.
Near-Instant Reward Delivery
Once you submit a valid voucher:- Verification happens in milliseconds
- SOL transfers in the same transaction
- No waiting periods or additional steps
Minimal On-Chain Logic
The smart contract only validates signatures and transfers funds. Complex eligibility logic stays off-chain, allowing:- Flexible criteria that can evolve over time
- Lower gas costs (simple operations on-chain)
- Reduced attack surface (less code = fewer vulnerabilities)
Replay Protection and Security
Additional security measures:- Expiration timestamps: Vouchers expire after a set period (e.g., 30 days)
- Signature verification: Only vouchers signed by the authorized backend can be claimed
- Recipient validation: Voucher can only be claimed by the specified wallet address

Reward Calculation Methodology
While specific formulas vary by reward type, common factors include:For Airdrop Distributions
- Trading volume: More volume = larger share of the distribution
- Token diversity: Trading across multiple tokens may increase rewards
- Consistency: Regular participation may be weighted higher
- Time period: Activity within the specific distribution window
For Cashback Distributions
- Exposure to failed tokens: Holding tokens that failed or got rugged
- Loss magnitude: Larger losses may receive proportionally higher cashback
- Participation timing: When you entered/exited relative to the failure
- Vault balance: Total cashback divided among eligible users
Exact formulas are determined by the backend and may evolve over time to optimize fairness and incentivize healthy platform participation.
