How crypto casinos work
You send coins to an address the casino gives you, and once the network has confirmed the transfer, the casino adds it to your account balance. Every bet after that is a number changing in the casino's database. Cashing out puts coins back on the chain after the casino has checked and approved the request.

From deposit to withdrawal
- Pick coin and network. The cashier shows an address for one coin on one network, for example USDT on Tron.
- Send from your wallet or exchange. The transfer is public on the chain from the first second.
- Wait for confirmations. The casino counts blocks on top of yours and credits you at its own threshold.
- Play from the balance. Bets and wins change a number in the casino's database. No transaction leaves for any of them.
- Request a withdrawal. The casino checks the request, sometimes asks for ID, and sends coins from its own wallet.
- Receive. Your wallet shows the incoming transfer once the network includes it.
Before you copy the address, read the line above it. It names the coin and the network, say USDT on Tron, and the wallet must match it exactly. You usually won't need a memo, since casinos tend to hand each account its own address. XRP is different. The cashier shows a destination tag next to the address, and you paste both.
| Network | 1 confirmation | 3 confirmations | 12 confirmations |
|---|---|---|---|
| Bitcoin | 12 min | 36 min | 2.4 h |
| Litecoin | 3 min | 8 min | 30 min |
| Dogecoin | 1 min | 3 min | 13 min |
| Ethereum and ERC-20 tokens | 12 s | 36 s | 2 min |
| Tron and TRC-20 tokens | 3 s | 9 s | 36 s |
Wait = confirmations × average block time from the shared fee snapshot of 12 Nov 2026. These are averages: a single Bitcoin gap ran 55 minutes that day. Each casino picks its own number of confirmations, and the table only shows the arithmetic.
What happens when you press spin
Beltastic is a game studio on Engine, the platform behind Stake's outside-studio slots, so this is the part we see from the inside. The game never touches your coins. When a round starts, the game server asks the casino's wallet to take the bet from your balance. When the round ends, it asks the wallet to add the win. Amounts are whole numbers in the casino's currency units, and the casino can refuse a bet if your location or your limits don't allow it.
| Call | What it does |
|---|---|
| /wallet/authenticate | Checks the session the casino issued and returns balance, game settings and jurisdiction rules |
| /wallet/play | Starts a round and takes the bet from the balance |
| /wallet/end-round | Closes the round and pays out |
| /wallet/balance | Reads the current balance |
| Error ERR_LOC | Invalid player location |
| Error ERR_GLE | Gambling limits exceeded |
From the Engine API reference and the play endpoint. Other platforms name things differently, but the split is the same: the casino holds the money, the game server decides the result.
Provably fair and what it covers
Provably fair games publish a hash of the server seed before you bet. Rotate your seeds afterwards to reveal the real seed, hash it yourself and compare. Then run server seed, client seed and nonce through a verifier to get the result back. If it matches your bet history, the round wasn't changed after you placed it. Whether the casino pays you out is a question for its terms and its regulator.

Before you deposit
- The licence. Note the number and look it up in the regulator's register yourself, not through a badge on the casino's site.
- Your country. The terms name the countries a casino won't serve. A licence issued abroad says nothing about the law at home.
- Withdrawal rules. Minimums, fees per coin, and whether ID is needed above a certain amount.
- Bonus terms. Wagering requirements can lock a deposit until you have bet it many times over.
- Network match. Coin and network on the cashier page, against what your wallet is set to.
- A small test. Send a small amount first and withdraw part of it before you move more.
- Your limits. Deposit and loss limits in the account settings, set before the first bet.
Withdrawals are slower than deposits for a plain reason. A deposit only needs the network. A withdrawal needs the casino to act, and many hold larger payouts for a manual review or an ID check. If yours sits pending, write to support with the time of the request and the amount, and ask whether it's waiting on review or on ID.

Questions
How do crypto casinos work?
You send coins to a deposit address, the casino credits them to an account balance after enough confirmations, and you play from that balance. Bets don't go on the blockchain. Withdrawals are sent from the casino's wallet back to yours.
Are crypto casinos safe?
Some are run carefully and some are not, and the coins sit with the casino while you play. Check the licence in the regulator's own register, test with a small withdrawal, and keep only what you plan to play with on the site.
Why is my crypto casino withdrawal pending?
Usually because the casino has not sent it yet: manual review, an ID request or a daily limit. Once it is sent, a transaction hash exists and the network part takes seconds to about an hour depending on the coin.
Do crypto casinos need ID?
Many ask for it at some point, often before a large withdrawal, because licences come with anti-money-laundering rules. The terms say when.
