Understand the risks

Smart-contract risk

A defect could lock or misallocate funds. The deployment cannot be patched or restarted. More than 730 days after abort, the fee recipient can sweep all remaining ETH, potentially leaving unclaimed refunds, bounties and share redemptions without backing.

Experimental cryptography

Correct settlement depends on Ethereum header semantics, BLS precompiles and the pinned drand network.

Liquidity, fees and loss

Bankroll shares absorb lottery outcomes. NAV can fall, profitable new highs dilute holders through a 10% share-paid fee, below-HWM primary-mint premiums remain in the bankroll, and liquidity exists only between rounds.

Resolver availability

Settlement requires a public resolver transaction. Bounties encourage delivery but do not guarantee timing.

Wallet and RPC risk

Wallet software, browser extensions, RPC providers and phishing can misrepresent or redirect an intended action.

Legal and tax risk

Lottery, gambling, securities, sanctions and tax rules vary. You are responsible for your jurisdiction.

Sepolia ETH and LUCK in this deployment are test assets with no monetary value. Luckotto is experimental, unaudited software—not financial, legal, tax, or investment advice.
