One purchase. Two draws.
This is a paid lottery. A ticket costs 1 USDC on Base. Purchases are non-refundable and winning is not guaranteed. The ticket contract is deployed on Base mainnet. The previous savings contract is available separately in the legacy archive.
Where your payment goes
50% of each payment is allocated to the daily pool and 50% to the weekly pool. A 5% project fee is deducted from each half. For 100 USDC: 47.50 goes to daily prizes, 47.50 to weekly prizes and 5 to the project. Pool counters show amounts after fees. The remaining USDC stays in the contract until payout; it is not deposited into Aave.
Entries and timing
Each ticket enters only its purchase day's draw and the current weekly period. The daily result does not affect the weekly entry. Days close at 00:00 UTC (03:00 Moscow time); a week is seven days from the contract's first day. A stale purchase quote is rejected when the period changes. Odds are proportional to the number of paid tickets; holding funds for longer does not add weight.
Winners
One randomly selected winner receives the daily pool. The weekly draw has four distinct winning addresses: the grand prize receives 60% plus rounding dust, while three other addresses share 40% equally. Distinct addresses do not necessarily represent different people. If fewer than four eligible addresses participate, the weekly pool and its tickets roll over to the next period.
Payouts and delays
The period closes first, then Chainlink VRF returns a random number, and a separate transaction settles the draw. During settlement the contract attempts to transfer USDC to the winners. If a transfer fails, the prize remains assigned to the winner; anyone can retry payment to that same address. The recipient cannot be changed, the randomness request cannot be cancelled, and the same pool cannot be redrawn. There is no administrative withdrawal of prize pools. Gas and VRF require separate funding; the network, oracle or USDC may delay operations.
Other cryptocurrencies
LI.FI swaps supported cryptocurrencies into USDC on Base in your own wallet; ticket purchases are a separate step. Prizes are paid in USDC and can be swapped separately. Available assets, networks and routes depend on providers; support for every coin without exception is not promised. Do not transfer funds directly to the contract instead of using the purchase form.

Previous version
The legacy savings interface (in Russian) remains available for previous deposits and prize credits. It uses a different contract and a different mechanism.
