LuckyStash Overview
LuckyStash is a prize-linked savings account built on Solana that makes saving money exciting without any risk. When you deposit stablecoins into LuckyStash, you maintain full access to your principal at all times while gaining chances to win daily prizes funded by the shared yield pool.
Unlike traditional savings accounts that pay small amounts of interest to everyone, LuckyStash allows you to transform your potential interest into chances to win much larger prizes. You can also customize exactly how much yield you want to share versus keep as guaranteed returns.
Built on RebelFi's Smart Pools technology, LuckyStash demonstrates how DeFi can create financial products that simply weren't possible before blockchain.
How It Works
Open a Savings Account: Deposit USDC (or other supported stablecoins) into your LuckyStash account.
Customize Your Yield Allocation: Set exactly how much of your yield to share with the prize pool:
Share 100% for maximum prize chances (standard prize-linked savings)
Share 0% for maximum personal yield (standard savings account)
Choose any percentage in between to balance guaranteed returns with prize opportunities
Earn Returns Your Way: Based on your yield allocation settings, you'll receive:
Your personal yield portion as guaranteed returns (at current DeFi lending rates)
Entry tickets for prize drawings based on your shared yield portion
Full Control of Your Funds: Access and withdraw your principal anytime with no penalties or lockups.
How Winners Are Selected
LuckyStash uses a transparent, verifiable system to select prize winners that balances user participation with randomness. Here's how it works:
Winner Selection Factors
Your chance of winning in each drawing is determined by several weighted factors:
Deposit Amount (Primary Factor): The more you deposit, the greater your chances. Someone with 1,000 USDC deposited will have 10x the base chance of someone with 100 USDC.
Yield Sharing Percentage: The higher percentage of yield you choose to share with the prize pool, the better your chances of winning from that pool.
Boosters: These special enhancements increase your winning odds without requiring additional deposits. Earn Boosters through referrals, community participation, and special promotions.
Fair Random Selection
We use a verifiable method to ensure fair and transparent prize drawings:
Future Block Hash Seeding: Each drawing uses the hash of a predetermined future Solana block as the random number generator seed. Since this block hasn't been created yet when the drawing period begins, no one (including us) can predict or influence the outcome.
Transparent Formula: We use a published formula (detailed below) to determine winners based on the random seed and participant data.
Weighted Random Selection: Once the seed block is reached, our selection algorithm performs a weighted random selection based on each participant's factors (deposit amount, yield sharing, and Boosters).
Winner Selection Formula
Here's how we select winners:
Step 1: Order all participants by their Solana deposit address
Step 2: Calculate each user's weighted points:
Step 3: Calculate total pool points:
Step 4: Assign each user a probability range:
Step 5: Generate random number using block hash:
Step 6: Select winner:
Verification
While the winner selection process isn't automatically verified on-chain, anyone can verify any drawing's fairness by:
Checking the predetermined block hash used as the random seed
Reviewing the on-chain deposit data for all participants
Applying our published selection formula to confirm the winner was correctly selected
We publish all the necessary information after each drawing, allowing full transparency into the selection process.
