How it works
Fair by design.
All on-chain.
You only risk the interest, never the cash you put in. The pot, your odds, and every draw live on-chain, so you can check them yourself.
Your deposit never goes into the pot. Only the interest does. Take your deposit out whenever you want.
You keep your money
Your USDC goes into Blend and keeps earning. The contract can only ever pay out the interest, never your deposit. The math always adds up to exactly what people put in, and you can pull your money out any time.
The prize is the interest
Everyone's USDC earns interest on Blend, a lending app on Stellar. As it earns, the pool grows past what people put in. That extra bit is the prize. More savers and more time make it bigger.
How a winner is picked
You get tickets for how much you save and how long you keep it in, so a last-minute deposit can't take over. Once a day at 00:00 UTC, one winner is picked at random, weighted by tickets. Today that randomness runs on commit-reveal; on mainnet it moves to VRF, which no one can rig.
Check it yourself
Your odds are just your tickets divided by everyone's tickets. Every deposit, withdrawal, and draw is written on-chain. The contract is open, so you can look up the pot, the winners, and every payout.
A plain example
Two people save. One draw a day. Nobody loses their money.
Alice
- Deposit
- $100
- Held for
- 10 days
- Tickets
- 1,000
- Odds
- 40%
Bob
- Deposit
- $300
- Held for
- 5 days
- Tickets
- 1,500
- Odds
- 60%
- 1
Tickets come from amount and time
Alice: 100 × 10 = 1,000. Bob: 300 × 5 = 1,500. Together that is 2,500 tickets.
- 2
Odds are your share of the tickets
Alice has 1,000 of 2,500, so 40%. Bob has 1,500 of 2,500, so 60%.
- 3
The pot is only the interest
Their $400 earns interest on Blend. Say it made $2 since the last draw. The pot is that $2, not the $400.
- 4
One winner, picked by tickets
Bob is more likely at 60%, but Alice can still win. Say Bob wins. He gets the $2 straight to his wallet.
- 5
Nobody loses
Alice still has her $100. Bob still has his $300. The pot resets and starts filling up for tomorrow.
