1️⃣

Deposit USDC

Your deposit joins the pool and buys you tickets — odds proportional to your share. Withdraw the full amount anytime.

2️⃣

Prize pool grows

Deposits earn yield in the Lunex ERC-4626 vault — everything above principal (plus sponsor top-ups) becomes the prize. Your principal is never touched.

3️⃣

Daily draw

Every 24h anyone can trigger the permissionless draw. One saver wins the whole prize. Everyone else loses nothing.

Testnet honesty: randomness is prevrandao+blockhash (mainnet would use VRF), winner selection is O(n), and ERC-4626 rounding can cost a wei or two. All limitations are documented in the README.
