Save. Earn. Someone wins.
YieldJack pools savings, puts the deposits to work, and turns the yield they generate into recurring prizes — while every saver keeps their own tracked principal. $JACK stakers earn a share of YieldJack's creator-fee revenue on top.
Figures populate once the production vault and prize engine are deployed — see Transparency.
Save & Win
Pooled savings, personal principal, shared upside
YieldJack turns the yield generated by pooled deposits into recurring prizes for eligible savers — without touching what each saver put in.
Your principal stays yours
Deposits are tracked per-wallet and accounted for separately from prize funds — withdraw your tracked principal whenever the production contracts allow it.
Yield funds the prize, never principal
Only realized yield generated by the pooled deposits can ever fund a round's prize. Principal accounting and prize accounting never mix.
Eligible savers enter every round
Depositors are automatically eligible for recurring draws while their funds are in the vault — no separate ticket purchase or lockup required.
$JACK
JACK ties trading activity to real, streamed rewards
Stake JACK to earn a share of YieldJack's creator-fee revenue in WETH — routed on-chain through a permissionless fee router, never a promise.

Operations & security
Infrastructure and safety work
Documented split from JackFeeRouter's immutable constructor parameters — shown ahead of deployment. These percentages apply to YieldJack's creator-fee revenue after applicable Pons protocol fees—not to gross trading volume.
Every $JACK trade that generates creator-fee revenue routes it to JackFeeRouter. Anyone can permissionlessly call its harvest function, which wraps received ETH to WETH and splits it 70/20/10 between stakers, the prize reserve, and operations.
How saving works
Three steps, every round
The same lifecycle repeats every round: deposit, let yield accrue, then a winner is drawn while everyone keeps their principal.
Deposit
Deposit the supported savings asset into the vault. Your principal is tracked to your wallet from that moment on.
Yield accrues
The vault routes pooled deposits into a verified yield source. Realized yield — never principal — builds toward the round's prize.
Draw or withdraw
When a round closes, one eligible depositor is drawn to win the accrued prize. Withdraw your principal according to the production contracts, any time.
Creator revenue
From a JACK trade to a staking reward
No off-chain promise — the flow from trading activity to a staker's claimable WETH happens entirely through permissionless, on-chain calls.
