How JackCo Works
3 simple steps — no DeFi expertise needed
Deposit USDC
Send your USDC (a stablecoin pegged 1:1 to the US dollar) to JackCo. Think of it like a savings account.
Your Money Earns Interest
JackCo routes your deposit across multiple audited DeFi yield strategies (Aave, Morpho, Sky DSR, and more), earning 4–10% APY. Each strategy is capped at 40% max allocation. You don't need to do anything.
Win Weekly Prizes
All the interest earned by everyone is pooled together and distributed to lucky winners every 7 days. Your original deposit is always safe.
Yield Strategies
Your deposit is diversified across multiple protocols — no single point of failure
USDC → aUSDC, instant liquidity
Better rates via peer-to-peer matching
Backed by MakerDAO reserves
No viable USDC restaking market yet — activates when one opens
Min 3 maturity spread, auto-rollover 30d before expiry
How Win Probability Works
The more you deposit and the longer you keep it, the higher your chance
Your Share
Your probability is proportional to the percentage of the total pool you represent. Deposit more = bigger share = higher chance.
Time Matters
JackCo uses TWAB (Time-Weighted Average Balance). The longer you keep your deposit, the stronger your position.
More Winners = Better Odds
As JackCo grows, more winners are drawn each week. Your chance of winning increases automatically.
Chance = 1 − (1 − yourShare)^numberOfWinners
Example: You deposited $100 into a $10,000 pool (1% share). With 5 winners: 1 − (1−0.01)^5 ≈ 4.9% per draw
Growth Phases
The more users join, the more winners — everyone benefits
Phase upgrades happen automatically — no action needed from users.
