On-Chain Casinos 2026: what really settles on the chain

The score is for the on-chain part alone: where the balance sits, how outcomes are decided, whether the bankroll can be inspected, and whether the proof is a document or a badge. The overall review score is on each review page.

1. 01

   Just.bet

   7.8On-chain score

   Balance in a contract outcomes on a server, by clause 6 of its own terms

   

   Your balance

   An escrow contract on Arbitrum, with an emergency exit by Merkle proof if the platform is offline

   Bet outcomes

   HMAC-SHA256 over a server seed, your client seed and a nonce, computed on Just.bet's servers; the terms say outcomes are not recorded on a blockchain

   The bankroll

   A WINR Bankroll contract funded by liquidity providers, shown on a Proof of Bankroll page

   Licence

   None. Clause 1 of the terms says so, and disputes go to the courts of Costa Rica

   Just.bet is the most on-chain casino of the 10 in this review, and the terms of Just.bet are the most transparent of where that stops. Funds are escrowed in a contract, and the bankroll that pays prizes is a WINR contract that’s funded by liquidity providers. The terms also state that in the case of an emergency, players can withdraw funds from the contract.

   The outcomes are not on the chain, and clause 6 says it in three parts: game results are not recorded on a blockchain, are not generated by a verifiable random function, and do not carry per-bet cryptographic proofs. Instead, they use a commit-and-reveal scheme, and publish a hash of the server seed before the bet, and perform rotation after every 1,000 bets, and reveal the server seed so bets made under it can be recomputed. The terms refer to the product as hybrid and not fully decentralized.

   The cost of the contract is everything else. Clause 1 states that JustBet does not hold a gaming license anywhere and that Costa Rica does not regulate gambling; Clause 4 states that ID checks are permitted prior to withdrawals and there is no defined condition for when they are permitted; 27 countries are defined as restricted. There is no third party to contact about a dispute, which is addressed in the legality guide.

   • Your balance sits in an escrow contract on Arbitrum, with a Merkle-proof exit
   • The bankroll is a contract with a Proof of Bankroll page
   • A commit-and-reveal scheme described clause by clause

   • Outcomes are decided on a server, not a chain, by clause 6
   • No gaming licence anywhere, by clause 1
   • Verification before withdrawals with no published trigger

   Metawin

   6.2On-chain score

   Prize draws on a contract with Chainlink VRF on Ethereum and API3 QRNG on Base; the casino is custodial

   

   Your balance

   A Metawin balance the casino holds; coins swap in and swap back out for $2.50 with a $20 minimum

   Bet outcomes

   Studio games and originals on Metawin's side; nothing recorded on a chain

   What is on a chain

   The prize draws: entries are wallet transactions into a competition contract, the contract draws with a verifiable random number and transfers the prize

   Licence

   Anjouan, ALSI-202602025-FI1, valid on the validator on 8 October 2026

   Metawin started as a prize draw site, and the draws are the only part that is on chain. Entries to the draws are transactions to a smart contract, paid for in gas and are irreversible. The contract draws the winner using a verifiable random number. For Ethereum draws, it uses Chainlink’s VRF and for Base draws it uses API3’s QRNG. The contract and entry list are public, and the FAQ states that Metawin does not impact the outcome of the draws.

   Everything below the draws is an ordinary custodial casino. Deposits are swapped to a Metawin balance, the games are provided by 48 Studios, and the way out costs $2.50 with a $20 minimum and a 1x play-through of each deposit. The 30% Prize Funds credited to each deposit can buy draw entries, but only after the cash balance is 0.

   Two on-chain limits affect the draw component of the casino. The prize draws prohibit players from Ireland (though the casino does not), and the KYC policy allows photo ID, proof of address, and source of funds (which a contract draw does not change), to be provided at the casino’s discretion.

   • Draws decided by Chainlink VRF or API3 QRNG on a public contract
   • Any WalletConnect wallet is the account, with nothing to fill in
   • Licence valid on the Anjouan validator

   • The casino balance is custodial; only the draws touch a chain
   • $2.50 withdrawal fee with a $20 minimum
   • Prize draws bar Irish players

   Dexsport

   5.6On-chain score

   A sportsbook pool on contracts Dexsport says were audited; the reports are not linked

   

   Your balance

   A platform balance Dexsport holds, deposited from a connected wallet from about $0.10

   Bet outcomes

   Casino games from 48 outside studios; nothing settles on a chain

   What is on a chain

   The help centre says the sportsbook pays from a liquidity pool on smart contracts audited by CertiK and Pessimistic; the footer shows the badges

   Licence

   Anjouan, ALSI-202508043-FI2, in the footer with a verify seal

   Dexsport claims to be a decentralized crypto casino, and its terms require a connected wallet to be used as a sign-up method, which is not required by any other casinos here. In the help center, it is mentioned that the sportsbook pays from a liquidity pool on smart contracts, and the footer has Audits by CertiK, Pessimistic, and Echelon.

   The reports are not linked on the site, therefore the badges are Dexsport’s statements, and the casino side is ordinary custodial. Your deposit is a platform balance, the 7,700 games are provided by outside studios, and withdrawals are a cashier’s action with a fee set in the cashier. The deposit must be wagered twice to be cashed out.

   A wallet is the main form of identity at a Dexsport account. Referring to clause 3.3.1, only the account holder is allowed to access the profile. The account must be funded with at least $0.10. Our wallet login ranking places this second of 10.

   • The terms require a connected wallet; the address is the account
   • Sportsbook paid from a liquidity pool, per the help centre
   • About $0.10 minimum deposit from a wallet

   • Audit badges without linked reports
   • Casino balance custodial; studio games settle nowhere
   • Withdrawal fee shown only in the cashier

   BC.Game

   4.4On-chain score

   74 provably fair originals on a custodial balance you cannot inspect

   

   Your balance

   A BC.Game balance; the wallet is a login key, the balance is theirs to hold

   Bet outcomes

   74 originals with provably fair seeds, Crash at a published 99% return; slots and live tables from outside studios

   What is on a chain

   Deposits and withdrawals only: 150-plus coins, USDT on 16 networks, cheapest chain preselected

   Licence

   Anjouan, ALSI-202410011-FI1, valid on the regulator page on 6 October 2026

   The bottom seven casinos share a pattern, and BC.Game is the most notable example: a player’s wallet is used for signing in, the funds are represented in casino credits, and the verifiable part is the originals shelf. Seventy-four originals use provably fair seeds, with Crash at a published 99% return, and Plinko, Limbo, Keno, Mines, Dice and the table games beside it. The over 1,000 slots and the live dealer games are hosted and operated by third parties.

   Seeds, in the context of a provably fair system, allow a player to recompute the outcome of a game after the game is completed. A seed does not prove that the outcome was fair or that a player’s funds exist or a withdrawal will be honored. Clause 6.3 allows BC.Game to request for player ID and other forms of player identification at any time including before a payout and clause 6.2 outlines wallet ownership as one of the documents that BC.Game may request from a player.

   Money coming in and out of the account is what the blockchain captures at BC.Game. The cashier, which is the deepest part of the website, has 150+ cryptocurrencies, USDT on 16 blockchains with Tron as the default blockchain, USDC with the Base network as the default blockchain, a 1 USDT minimum, and withdrawal fees which are shown only at the last step.

   • 74 provably fair originals, Crash at a published 99% return
   • 150-plus coins, 16 USDT networks, cheap chain preselected
   • Licence checked valid on the Anjouan page

   • The balance is custodial; nothing settles on a chain
   • Identity checks allowed at any time, including before a payout
   • Withdrawal fee shown only at the preview step

   Bitcasino.io

   4.2On-chain score

   Provably fair originals with a verifier guide and a Live RTP page

   

   Your balance

   Bitcasino's, shown in milli-bitcoin or your chosen coin

   Bet outcomes

   Originals commit to a server seed hash with your client seed and a nonce; 9,500-plus studio games are not provably fair

   What is on a chain

   Deposits and withdrawals: 13 coins, USDC on Base, USDT on four networks, MetaMask connected in the cashier

   Licence

   Anjouan, ALSI-202509076-FI2, valid on the validator on 8 October 2026

   Bitcasino has been pretty fair when judging themselves. They are a custodial casino with a MetaMask button, not a Web3 casino. The originals offered are provably fair, by committing to a hash of the server seed and then combining it with the client seed and a nonce, and the site has a live RTP page showing recent returns per game and a verification guide.

   The 9,500-plus studio games offered by Bitcasino are outside that system, and the balance is theirs from the first deposit shown in milli-bitcoin, or your chosen coin. The Cashier is the only part of the site that is on the blockchain. There are USDC and USDT with various networks and 0.25 USDT minimums. MetaMask is linked for Ethereum deposits, and there is a 0.875% fee.

   There are no fees when withdrawing, and they are processed within minutes. By AML policy, there is a required identity verification the first time a withdrawal is made. A verified email is also required.

   • Originals provably fair with a published verifier guide
   • A Live RTP page of recent returns per game
   • Withdrawals in minutes with no fee from Bitcasino

   • Custodial balance; nothing settles on a chain
   • Verification at the first withdrawal of any amount
   • 0.875% MetaMask fee on the connected route

   BetFury

   4.1On-chain score

   24 provably fair originals behind a Curaçao licence that checks out

   

   Your balance

   A BetFury balance until you withdraw

   Bet outcomes

   24 originals with a published seed check; 11,000-plus slots and live tables from outside studios

   What is on a chain

   Deposits and withdrawals: 41 coins on 18 networks, 0.1 USDT minimum on Polygon

   Licence

   Curaçao, OGL/2024/1494/0942, active on the regulator's page on 8 October 2026

   Betfury has 6 wallet buttons at the front and nothing on a blockchain behind it. There is a wallet sign in to open an account and deposit, which holds the funds until withdrawal. The 11,000 slots and live tables offered by Betfury are from external game studios. The 24 originals offered by Betfury have a published seed, which is verifiable.

   The license is the important document here, and it is one of the better ones on the list. Curaçao, OGL/2024/1494/0942, is active on the regulator’s site, with a certificate of operation for Universe B Games B.V. Clause 17.2 states that a request for documentation can be made at any time and must be provided within 30 days. A request for an anti-fraud check may extend the withdrawal period by seven days.

   The cashier accepts 18 networks with a 0.1 USDT minimum on Polygon and 3 USDT on Ethereum. The welcome pack is the thing to read before any of this: a 590% bonus with a payout capped at 1.2 times the bonus.

   • Curaçao licence active on the regulator's page
   • 24 provably fair originals with a published seed check
   • 0.1 USDT minimum on Polygon

   • Custodial balance; nothing settles on a chain
   • Bonus payout capped at 1.2x the bonus
   • Anti-fraud hold of up to seven days

   Solcasino

   4.0On-chain score

   Solana payouts, custodial balance with the wallet named as the login in the terms

   

   Your balance

   A member account in Solcasino's books until a withdrawal

   Bet outcomes

   Originals provably fair with a hashed server seed; slots, live and sports from outside providers

   What is on a chain

   Deposits and withdrawals: 47 tokens, Solana payouts after one confirmation, no fee back to a Web3 wallet

   Licence

   Tobique Gaming Commission, valid on the validator on 8 October 2026

   Solcasino's wallet is the login by clause 3.1.3 of the terms, and the deposit leaves it for Solcasino's books the moment it lands. The originals are provably fair in the usual way, a hashed server seed shown before the bet, your client seed and a nonce; the slots, live tables, sports and the 1000x futures desk are outside that scheme.

   The chain shows up on the way out rather than the way in. A withdrawal to a Web3 wallet carries no fee, and payouts in Solana are processed after one confirmation. The terms and conditions set a target of one hour with a 10 minute average, and a $10,000 limit per token per day.

   Clause 3.2.6 allows Sumsub identity checks when processing deposits. Clause 3.3.5 allows the payments team to check documents, so the wallet login buys no exemption. Tobique’s license validates on the regulator’s page, which tells more than a contract address can.

   • No fee back to a Web3 wallet; Solana payouts after one confirmation
   • The terms name the wallet as the login
   • Tobique licence valid on the regulator's validator

   • Custodial balance; nothing settles on a chain
   • $10,000 per token per day withdrawal limit
   • Sumsub checks at deposit or withdrawal, at discretion

   Roobet

   3.8On-chain score

   Instant withdrawals from a balance Roobet holds, after a name-and-address form

   

   Your balance

   Roobet's; the MetaMask signature opens an account, the form before the first deposit asks for your name and address

   Bet outcomes

   14 originals provably fair; over 7,000 studio games are not

   What is on a chain

   Deposits and withdrawals: 11 coins, ETH on Ethereum, Base or Arbitrum, every withdrawal sent the moment it is requested

   Licence

   Curaçao, OGL/2024/687/0427, active on the regulator's page on 6 October 2026

   Roobet’s chain carries the withdrawal. The help center says every withdrawal is sent the moment it is requested, with the only thing to wait for being the confirmations of the network, and there’s no casino fee; the condition in front of it is that every deposit is wagered at least once. Provably Fair applies to the 14 originals, and the 7,000 plus slots that Roobet offers are studio releases.

   The balance is Roobet’s, and the account behind the MetaMask signature asks for more than most: first, last name, date of birth, country and address, prior to the first deposit, and documents prior to large withdrawals, under clause 4.9. The 25 countries mentioned are the UK, US, Australia and the Netherlands among others.

   The cashier's connect-to-deposit button, added in July 2025, sends from a connected wallet without a pasted address, and the licence is a Curaçao one with a certificate of operation naming Raw Entertainment B.V.

   • Every withdrawal sent at once with no casino fee
   • ETH accepted on Ethereum, Base or Arbitrum
   • Curaçao licence active on the regulator's page

   • Custodial balance; nothing settles on a chain
   • Name, birth date and address before the first deposit
   • Every deposit must be wagered once before any withdrawal

   Rollbit

   3.5On-chain score

   Nothing on a chain beyond the deposit, the withdrawal and the NFT vault

   

   Your balance

   A Rollbit cashier balance; the wallet is linked by one signed message

   Bet outcomes

   Slots, live, X-Roulette, X-Crash and a futures desk on Rollbit's side; no published seed scheme recorded in our review

   What is on a chain

   Deposits and withdrawals with no fee beyond gas, $5 minimums; NFT deposits signed with the same wallet

   Licence

   Anjouan, ALSI-042308006-FII, valid on the validator on 8 October 2026

   Reusing a signed message allows Rollbit to link a wallet to an account, and to a NFT deposit. That is the full extent of the chain’s involvement. The balance is Rollbit’s, the games are on Rollbit’s side, and the 1000x Futures desk that runs outside the gaming license is on the same balance.

   Fees are low. No fee beyond gas on deposits or withdrawals. Minimums are $5 in stablecoins and 0.002 ETH. A cash-out requires a $10 deposit and a $10 wager. Withdrawal times are not listed. The AML policy describes a five-level verification that can be requested level by level.

   The terms and conditions require your full name, date of birth, address, email and phone, with accuracy, and count a linked wallet in the one-account rule with the person, household, device and IP address. Twenty-nine countries are named as restricted, most of the EU among them.

   • No fee on deposits or withdrawals beyond gas
   • $10 deposited and $10 wagered is the whole cash-out condition
   • Licence valid on the Anjouan validator

   • Nothing settles on a chain
   • Five-level verification, requestable level by level
   • 1000x futures desk outside the gaming licence

    Fairspin

    3.2On-chain score

    The chain is gone from a site whose name once meant bets logged on one

    

    Your balance

    A Fairspin balance in dollars, euros or milli-bitcoin, not in the coin you sent

    Bet outcomes

    Games from 82 studios on their own servers

    What is on a chain

    Deposits and withdrawals only: 45-plus coins, 1,000 USDT a day out, no fee from Fairspin

    Licence

    Anjouan, ALSI-202508047-FI2, valid on the validator on 8 October 2026

    Fairspin was originally a casino where you can log your bets to a public blockchain. In 2026, the site is blockchain-less and all that remains is a rakeback token called TFS, and a 10-tier loyalty program and store. Read it as a loyalty program, because that is what it is; nothing about a bet can be verified outside the casino.

    Fairspin keeps your balance in USD or EUR and in milli-BTC rather than the coin you deposited, and caps withdrawals at 1,000 USDT a day, 5,000 a week, and 20,000 a month. Fairspin charges no fees.

    13.2 names 67 restricted countries, Ireland and 24 EU states among them, and the welcome offer is still shown to Irish users. The 82 studios, with Pragmatic Play alone at 1,029 titles, are the reason Fairspin is on this site at all.

    • No fee from Fairspin on deposits or withdrawals
    • 82 studios, the longest provider list of the ten
    • Licence valid on the Anjouan validator

    • Nothing settles on a chain; the former bet log is gone
    • 1,000 USDT a day withdrawal cap
    • 67 restricted countries including Ireland, served anyway
