On this site, "on-chain" is a tier on a public ladder, not a marketing word. An operator appears here only if we place it at T3 (a genuine on-chain artefact, such as a public treasury or bankroll contract) or T4 (game logic, randomness and payout in contracts on a public chain). Today that is 7 live operators. A tier marked "claimed" is the operator's own claim, which we have not confirmed.
A score marked SEED is a desk estimate: we have not deposit-tested that operator. A gold ring marks a payout record reconciled on-chain by us; it covers payouts only.
What "on-chain" means here
The ladder has five tiers, T0 to T4. Below T3, the chain is only a payment rail. The two tiers on this page are the ones you can check yourself:
T4 Fully on-chain
Game logic, randomness (on-chain RNG or a VRF) and payout all execute in contracts on a public chain, played from a self-custodied wallet. Anyone can replay the outcome from chain data.
T3 Hybrid
Crypto rails plus a genuine on-chain artefact — a public treasury or bankroll contract, or provably-fair originals anchored on-chain — while the games themselves still run mostly off-chain.
For contrast, T2 (where most crypto casinos sit): Deposits and withdrawals happen on-chain, but the games are a black box. Provably-fair seed pairs may be published, but they are the operator's own records: accounts, game logic and the bankroll live on private servers, and no bet is verifiable from chain data.
What it does not guarantee
That the operator will pay. A contract can be drained, paused or upgraded by whoever holds its keys.
That the code is safe. An audit, when there is one, covers one version of the code at one date.
That the tier is still current. Operators change their stack; every review carries its date.
Anything about the law where you live.

These operators pay us a commission. The order of this block is commercial, not a ranking: scores and ranks are set by the public grid and are never for sale.
A casino where at least part of the game (the bankroll, the randomness or the settlement of bets) runs in public smart contracts that anyone can inspect. On our ladder that is T3 (partly) or T4 (fully).
Is an on-chain casino safer?
Not automatically. It is more checkable: you can see the contracts and the money. It can still fail, be exploited or close, and this page lists on-chain casinos that did.
Why does a tier say "claimed"?
Because the operator states that tier and we have not yet confirmed it from chain data ourselves. We show it, flagged, rather than hide it or adopt it.
How can I check a T4 casino myself?
Find the game contract address in the operator's own documentation, open it in a block explorer for that chain, and look for your own bets and the payouts they trigger. The tiers guide walks through it.
