NFTs, trades, swaps, owned assets — must be genuinely on-chain. No DB fakes. No "we'll add it later." The chain is the source of truth or nothing is.
Paytables shown, house edges named, fees disclosed, RNG verifiable. The kind of casino your grandfather would have respected. No dark patterns.
Never punch back at hostile actors. Out-build them. The answer to extraction is not better extraction — it is something measurably more generous, in the open.
Every contract's upgrade authority is one wallet, controlled by one person. No multisig theater, no DAO games. Trust the human or don't.
