How it works

No sign-up or account is required. 1 USDC/USDT sent to the deposit address is 1 ticket for the current period (whole tokens only; a 2.5 USDC deposit is 2 tickets). Deposits on any other chain, or in any other token, aren't counted.

A period runs from 00:00 UTC on the 1st to 00:00 UTC on the 1st of the next month. Every qualifying deposit in that window adds to both the pot and your ticket count. The winner gets 90% of the whole pot, including any fractional remainder beyond ticketed amounts, and 10% is kept as an operator fee.

At 00:00 UTC on the 1st, the draw uses the hash of the first Ethereum block created after that moment as its random seed. That block doesn't exist yet when the month ends, so it can't be predicted. And because it's always that first block, not whichever one happens to be around later, nobody can cherry-pick a better result.

Every entry is laid out as a ticket range in on-chain order (block number, then position within it), the same order anyone can independently derive by reading the chain. The winning ticket is winning_ticket = keccak256(seed_block_hash) mod total_tickets. Give anyone the period's entries and the published seed block, and they'll land on the exact same winner. No server, no database, no trusting us required.
