Web3 sportsbooks take bets from a crypto wallet and pay winners from a shared pool of funds, while smart contracts or the operator records the result. Three pieces do the work: the wallet that signs, the pool that pays and the settlement step that decides who gets what.
Each piece swaps a familiar part of an online bookmaker for a crypto equivalent. Logins become wallet signatures, the bookmaker's own balance sheet becomes a pool, and a results desk becomes an oracle or a published data source.
One bet, traced from wallet to payout, shows how the pieces fit together.
Online bookmakers start with a username, a password, and a stored balance. Web3 sportsbooks start with a wallet such as MetaMask, Trust Wallet, or Phantom, which proves ownership through a cryptographic signature.
Two kinds of requests pop up in the wallet. Signature requests prove you control the address and are free. Transaction requests move funds on-chain and cost a network fee, often called gas.
Token approvals deserve a closer look. Before a contract can spend a stablecoin such as USDT, the wallet asks you to approve an allowance, sometimes with an unlimited amount. Allowance checkers on block explorers show which contracts hold that permission and let you cancel it. Our comparison of each betting wallet option covers network support and signing features.
Funds behind a bet have to stay somewhere, and Web3 sportsbooks use three main designs to hold them.
Liquidity providers deposit funds into a shared pool, and that pool acts as the counterparty to every bet. Bettors win from the pool and lose into it, while providers earn or lose based on overall results. Azuro and Overtime both use pool-based models across several networks.
Exchange-style platforms match one bettor against another through an order book, much like a stock exchange. SX Bet works this way on its own network, so the price depends on what other users offer.
Hybrid platforms keep a pool that the operator manages, with deposits added to it and withdrawals taken from it. Players still connect their own wallets, yet the operator sets odds, accepts bets and settles results under its published rules.
Pricing depends on the design. Pool-based protocols take opening lines from odds feeds and then adjust them as bets build exposure on one side. Order-book exchanges let users quote their own prices, so odds move with supply and demand.
Operator-run books price markets much like a traditional bookmaker, with traders or third-party feeds behind the lines. Each design builds in a margin somewhere, either in the odds, in a fee on winnings or in the spread between back and lay prices.
Once the match ends, someone has to tell the system who won. Fully on-chain protocols use oracles, services that bring outside data such as final scores onto the blockchain. The smart contract reads the oracle and releases winnings to the right wallets.
Hybrid platforms settle from named data sources, then credit balances under their own rules. Some record bets or payouts on-chain, which lets anyone view the transactions, though the decision itself still rests with the operator. Our explainer on on-chain settlement separates what a block explorer proves from what it leaves open.
Every design trades control, convenience and recourse in its own way. The table sets the main differences side by side.

Recourse deserves equal weight with transparency. Licensed operators answer to a regulator, while a pure protocol may offer only a forum or token vote. Our look at decentralised sportsbooks compares both sides in more depth.
Dexsport describes itself in its terms as a community-driven interface to the Dexsport Protocol, where games play out between users' liquidity. All deposits join a liquidity pool, withdrawals come out of it, and the wallet remains user-owned, since Dexsport does not hold private keys.
Players connect through MetaMask, Trust Wallet, TronLink, Bitget Wallet, WalletConnect and other options, or sign up by email, which generates a wallet. Sports results draw on official league sources, with WhoScored as the primary statistics feed and Flashscore as a fallback.
Dexsport's prediction markets use a shared pool topped up by investors, with its balance publicly visible, while the team validates each market's resolution within 24 hours. Dexapp LTD operates the platform under an Anjouan licence, and a deposit unlocks for withdrawal once the player stakes its full value on sports picks at 1.3 or more.
Self-custody brings control along with responsibilities that a traditional bookmaker would handle:
Lost keys: seed phrase loss means wallet loss, since wallets lack a password reset
Open approvals: unlimited token allowances remain live until you revoke them
Contract bugs: smart contract flaws can freeze or drain a pool, even after an audit
Network fees: gas costs add up across deposits, bets and withdrawals on busy chains
Oracle errors: faulty data feeds can settle a market incorrectly before anyone spots it
Web3 sportsbooks rebuild the bookmaker from three parts: a wallet that signs instead of a login, a pool or order book that pays instead of a house balance sheet, and settlement through oracles or published data sources. Peer-to-pool, peer-to-peer and operator-run designs each place control and recourse in different hands.
Transparency varies with the model, from deposit records alone to fully on-chain bets. Self-custody also hands key management, approvals and fee costs to the bettor.
