These are the operators in our index that accept Ethereum L2 (3 today), ranked by public trust score, never by sponsorship. Accepting Ethereum L2 tells you where your deposit settles. It does not tell you that the games run on Ethereum L2, that the bankroll is visible there, or that the operator pays out. For that, look at the on-chain tier and read the review.
Chains in this group: Base, Arbitrum and Optimism.

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.

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.

Public block explorers for Ethereum L2: Basescan (Base), Arbiscan (Arbitrum) and Optimistic Etherscan (Optimism). We name them for convenience only; we have no relationship with them.
Not necessarily. Most operators that accept Ethereum L2 use it only for deposits and withdrawals, while games, balances and the bankroll stay off-chain (tier T2). Only tiers T3 and T4 put part of the casino itself on a public chain.
By the public trust score, the same order as the main ranking. Sponsorship never changes a score or a position, and a total marked SEED is a desk estimate: we have not deposit-tested that operator. VERIFIED covers payouts reconciled on-chain by us, never the whole score.
It makes them visible: once a withdrawal is sent you can see it on-chain. It does not oblige the operator to send it. A custodial operator can still delay or refuse a withdrawal, for example during a KYC check.
Partly. With a public explorer you can verify your own transactions and any address the operator publishes. You cannot verify off-chain game logic, or the total a custodial operator owes its players.
