Proof, not promises
Everything here is on-chain.
There is no private database and no hidden ledger. Every deposit, withdrawal, drawing, winner, and charitable gift is a public record on Base. The contract's source is verified — anyone can read exactly what the code does, and confirm it can never reach your principal.

The Rules, In Code
Fixed, automated, no discretion.
The split
90 / 5 / 5
Of the interest only: 90% to one winner, 5% to charity, 5% to the platform. Principal is never part of the split.
The cadence
Weekly
One drawing every 7 days, fired automatically by Chainlink Automation — no human chooses the timing.
The odds
Equal per dollar. Every $1 deposited is one equal, verifiable chance. Splitting funds across wallets gives no advantage.
The randomness
Chainlink VRF v2.5 — cryptographically provable on-chain randomness. The operator cannot influence who wins.
The operator
The platform's own address can deposit but is excluded from ever winning, in code.
Your principal
No function exists by which any operator can move your deposit. Only interest above tracked principal is ever distributed.
The Record
Every drawing, every gift.
