Name your payout
Choose a test-ETH stake and target payout. The bankroll limits exposure and the final pot determines the ticket’s exact economics.

Chance without a house.
Luckotto is an immutable weekly ETH lottery. Players choose a stake and target payout; investors own the bankroll through transferable LUCK shares. Ethereum and drand settle each result without an administrator choosing the outcome.
Testnet only. No real money, promised returns, or financial advice.

One protocol · Three roles
Designed so nobody gets to pick the winner.
Luckotto fixes its inputs before the draw. Participants interact directly with an immutable contract; independent resolvers only deliver public proof material.
Back the bankroll
During the liquidity window, mint or redeem ERC-20 LUCK shares against the protocol’s unreserved equity at transparent NAV.
Explore shares →Recompute the draw
A fixed future block, authenticated execution header, PREVRANDAO and a mechanically selected drand quicknet signature produce the result.
Inspect the design →The core promise
The rules are software, not a terms page.
There is no upgrade proxy, restart, or hidden balance. Abort authority ends before entropy exists; after abort, users have over 730 days to withdraw before the immutable fee recipient can sweep the complete remaining balance.
