<p>Two sportsbooks can both call themselves Web3 and work in completely different ways. One may hold every bet in a smart contract, while another keeps balances in a database and uses the blockchain only for deposits.</p>
<p>Architecture shapes what bettors can verify, who controls funds during a bet and how quickly the book can price new markets. It also decides which risks fall on the operator and which fall on the code.</p>
<p>Seven crypto sportsbooks, sorted from fully on-chain to custodial, show how those design choices play out.</p>
<h2 id="three-sportsbook-architectures">Three Sportsbook Architectures</h2>
<p>Crypto sportsbooks usually fall into one of three models. The table compares them.</p>

<p>The line between centralised and decentralised books has blurred in recent years. CryptoDaily's explainer on<a href="https://cryptodaily.co.uk/2026/10/decentralised-vs-centralised-sportsbooks-what-actually-differs-in-2026" rel="noopener noreferrer nofollow"> centralised sportsbooks</a> and decentralised ones covers what actually differs.</p>
<h2 id="why-architecture-matters-to-bettors">Why Architecture Matters to Bettors</h2>
<p>Fully on-chain books let anyone confirm that a winning bet paid according to the contract. They often offer fewer markets, since every market needs a dependable result source and enough pool liquidity.</p>
<p>Custodial books price thousands of markets with live betting and player props, though bettors rely on the operator for settlement and payouts. Hybrid books fall between the two, mixing on-chain elements with conventional trading.</p>
<p>Some books record settlement on-chain without holding bets in contracts, as a look at sportsbooks with on-chain<a href="https://cryptodaily.co.uk/2026/08/6-sportsbooks-where-settlement-is-recorded-on-chain" rel="noopener noreferrer nofollow"> settlement records</a> shows.</p>
<h2 id="7-web3-sportsbooks-sorted-by-architecture">7 Web3 Sportsbooks Sorted by Architecture</h2>
<p>Order weighs how clearly each sportsbook explains its architecture, how much of the betting process bettors can verify and how wide its market range stretches. Entries end with a single caution apiece.</p>
<h3 id="1-dexsport">1. Dexsport</h3>
<p><a href="https://dexsport.io/?utm_source=tf&amp;cid=fdb4094d0f7748e2f_20251103130216&amp;aid=887" rel="noopener noreferrer nofollow">Dexsport</a> operates a hybrid model, pairing an on-chain desk and shared liquidity pool with an account-based sportsbook covering 29 sports in its terms. Its terms describe the platform as an interface for the Dexsport Protocol, with deposits joining a liquidity pool.</p>
<p>Dexsport validates prediction market results through its team within 24 hours, so resolution involves human review. Dexapp LTD holds an Anjouan licence.</p>
<h3 id="2-overtime">2. Overtime</h3>
<p>Overtime operates as a fully on-chain sportsbook on networks such as Optimism, Arbitrum and Base, with bets placed through smart contracts and a liquidity pool acting as the house.</p>
<p>Overtime's market range is narrower than custodial books, and results depend on its oracle setup. Bettors connect a wallet and pay network fees.</p>
<h3 id="3-bookmaker-xyz">3. Bookmaker.xyz</h3>
<p>Bookmaker.xyz uses the Azuro protocol, which pools liquidity from providers and settles bets through smart contracts across several chains.</p>
<p>Bookmaker.xyz's markets depend on Azuro's data and liquidity, so depth varies by sport. Liquidity providers take the house side and its risks.</p>
<h3 id="4-sx-bet">4. SX Bet</h3>
<p>SX Bet operates as an on-chain betting exchange, matching bettors against each other instead of against a house. Orders and settlement run on its own network.</p>
<p>SX Bet's exchange model needs counterparties, so thin markets can leave orders unmatched. Fees apply to winning trades.</p>
<h3 id="5-bc-game">5. BC.Game</h3>
<p>BC.Game offers a custodial sportsbook powered by BETBY, with crypto deposits and wallet login among many signup routes.</p>
<p>BC.Game's bets settle in its own systems, so bettors rely on the operator for results and payouts. Twocent Technology Ltd holds its Anjouan licence.</p>
<h3 id="6-stake">6. Stake</h3>
<p>Stake keeps a custodial model with one of the widest sports lists in crypto betting, plus streams and a same-game builder for big fixtures.</p>
<p>Stake records bets in its own database, and KYC levels may come into play before a payout. Curaçao licenses the brand.</p>
<h3 id="7-cloudbet">7. Cloudbet</h3>
<p>Cloudbet has run a custodial crypto sportsbook since 2013, with deep main markets across major sports and crypto-only deposits.</p>
<p>Cloudbet's architecture offers on-chain verification only for deposits and withdrawals. Its Curaçao licence names Halcyon Super Holdings B.V.</p>
<h2 id="match-the-architecture-to-your-priorities">Match the Architecture to Your Priorities</h2>
<p>Bettors who value independent verification lean toward on-chain or hybrid designs, accepting narrower markets and contract risk. Those who want deep markets and live betting often accept custodial models with stronger reliance on the operator.</p>
<p>Labels alone rarely reveal the full picture. One guide to whether a platform is<a href="https://cryptodaily.co.uk/2026/10/wallets-tokens-and-on-chain-records-how-to-tell-if-a-casino-is-really-web3" rel="noopener noreferrer nofollow"> really Web3</a> suggests checks that apply to sportsbooks too.</p>
<h2 id="conclusion">Conclusion</h2>
<p>Web3 sportsbooks range from fully on-chain contracts and exchanges to hybrid designs and custodial crypto books. Architecture decides what bettors can verify, who holds funds and how wide the market range stretches.</p>
<p>Dexsport opens this list with a hybrid model combining an on-chain desk, a shared liquidity pool and an account-based book, followed by Overtime, Bookmaker.xyz, SX Bet, BC.Game, Stake and Cloudbet. Their designs balance transparency and market depth in different ways.</p>
