How it works
Prizes
Mock yield enters PrizePool only. Principal never funds a tier.
Draw
Each slot stores encrypted FHE randomness. You check your own range.
Claim or withdraw
Decrypt locally, claim privately, or withdraw anytime.
Visible vs sealed
The pool is auditable. Your position is not.
PUBLIC
Visible to everyone
- Principal TVL (aggregate)
- Tier allocations, reserve, slot counts
- Draw lifecycle and snapshot version
- Verified contract code
SEALED
Sealed to you
- Your deposit and balance
- Your odds of winning
- Whether you won or lost a slot
- Your prize amount
Auditable pool. Private position.
Built for sealed savings
Three hard boundaries keep principal, prizes, and private state apart.
Principal stays yours
ERC-7984 deposits sit in ConfidentialVault and stay withdrawable at any time. Draws never lock principal.
Prizes never spend principal
Available prize liquidity is sponsor-funded mock yield in PrizePool — a separate custody domain from saver balances.
You decrypt locally
Winner checks are pull-based per slot. Outcomes stay encrypted onchain; only your client decrypts via EIP-712 authorization.
The contracts
One principal vault and a separate prize pool on Zama fhEVM. Values stay encrypted onchain. You decrypt your own result locally.
ConfidentialVault
Custodies encrypted principal. Withdrawal stays open through every draw.

Can I lose my deposit?
No. Principal stays in ConfidentialVault and is withdrawable at any time. Prizes are paid only from PrizePool sponsor-funded mock yield.
If balances are encrypted, how can the draw be fair?
Each prize slot stores onchain FHE.randEuint64() randomness. Your client compares it to your encrypted range. Fairness does not require publishing your balance.
Can anyone tell whether I won?
No. A losing check and a winning check look the same onchain. Only you decrypt the result.
What can the public actually see?
Aggregates only: principal TVL, available prize liquidity, reserve, tier allocations, draw lifecycle, and snapshot versions.
What asset does the pool hold?
Curated ERC-7984 vaults, one asset each. The Sepolia faucet mints the selected vault's official mock underlying.
Is this live?
Yes. The verified Sepolia registry lists independent confidential wrapper vaults with isolated principal, draws, and prize liquidity.
