1%
An example house edge. On a pool it is the depositors' expected return per dollar wagered, before fees.
-
−$99,000
In the example, one winning $1,000 bet at 100x costs the pool $99,000, about two months of its expected result.

Code
The contract code sets the rules, and a vote by token holders can change them. Read what governance can change.
How a DeFi casino is built
A DeFi casino replaces the company bankroll with a pool in a smart contract. Anyone can deposit tokens into the pool and receive a share of it. Players bet against the pool: their losses grow it, their wins shrink it. A governance token, often run through a DAO, lets holders vote on settings such as fees, bet limits and which games run.
One bet, step by step
- You connect a wallet And approve the contract to spend the token you bet with.
- You place a bet The contract locks your stake and the most the pool could pay you.
- A random number arrives From a verifiable randomness service, with a proof checked on-chain.
- The contract settles It pays your wallet or moves your stake into the pool, in the same transaction flow.
What the pool earns, and what it can lose
Worked example, not a real protocol. Expected result = amount wagered × house edge. A 100x win pays the stake times 100, minus the stake.
DeFi casino vs a licensed crypto casino
| DeFi casino | Licensed crypto casino | |
|---|---|---|
| Who holds your money | Your wallet, until you bet | The casino, once you deposit |
| Who pays winnings | The pool contract | The operator |
| Rules | Public contract code | Terms and conditions |
| Disputes | Usually no one to complain to | The operator, then the licensing body |
| Main risk | Contract bugs, approvals, governance changes | Operator insolvency, hacks, withheld withdrawals |
| Responsible-gambling tools | Only if the protocol builds them in | Limits and self-exclusion, depending on the licence |
Summary of the two models. Check each casino's review for its licence and tools.
Risks to weigh
- Contract bugs. Pooled funds attract attackers, and one flaw in the code can drain a pool. Look for published audits, and remember that an audit is not a guarantee.
- Approvals. Approving a contract to spend your tokens without a limit lets it move them later. Approve only what you bet and revoke the rest.
- Governance. Token holders can vote to change fees or limits, and a few large holders can carry the vote.
- Legal status. Where the law does not recognise a DAO, it is unclear who is responsible, and gambling with an unlicensed protocol may be illegal where you live.
- No safety net. Without an operator there may be no deposit limit, cooling-off or self-exclusion. Set your own before you connect a wallet.

Terms
- Liquidity pool
- Tokens locked in a smart contract that act as the bankroll. So what: Depositors take the house's side of every bet.
- DAO
- An organisation run by votes recorded on a blockchain, usually weighted by token holdings. So what: Rules can change by vote; read what can be changed.
- Max payout
- The largest win a pool allows on one bet, usually a share of the pool. So what: Large bets may be refused or capped.
- Audit
- A security review of contract code by an outside firm. So what: Reduces risk, does not remove it.
DeFi casino FAQ
What is a DeFi casino?
A gambling app where smart contracts take bets and a liquidity pool funded by depositors acts as the bankroll, often governed by token holders.
How do liquidity pools work in a DeFi casino?
Depositors add tokens to the pool and own a share of it. Player losses grow the pool and wins shrink it, so depositors expect to earn the house edge on the volume wagered, minus fees, and absorb any big wins.
Are DeFi casinos safer than regular crypto casinos?
They carry different risks. You avoid trusting an operator with your balance, but you take on contract bugs, token approvals and the lack of any licensing body to complain to.
Can DeFi casinos be regulated?
Gambling laws apply to the activity wherever you are, whoever runs it. Where the law does not recognise a DAO, it is unclear who is responsible if something goes wrong.
Is the house edge lower at a DeFi casino?
Not by default. The edge is set in the contract or by governance and can match a regular casino's. Check the stated edge for each game.
