Quick answers to the most common questions. Where a topic has its own docs page, the answer links to it; the linked page is the full reference.

​
Getting started

​
What is My Crypto Casino?

My Crypto Casino (MCC) is a casino built on the Solana blockchain. All bets, payouts and game randomness are handled by a public on-chain program, so anyone can verify how the platform operates. MCC also features a Network system that lets players grow communities and earn a share of the casino’s profits. See the Introduction for the full picture.

​
How do I create an account?

Connect your Solana wallet, sign the requested message and accept the Terms of Service. That’s it: no email, no password, no referral code required, and nothing to pay: the sign-in signature is free and there is no account-creation transaction. Your on-chain account is created later, by your first deposit. See Wallets and connection.

​
Can I try the games without a wallet?

Yes. Demo mode runs the real games with play money, with no wallet, no sign-up and nothing to install. Demo bets win no money and earn no rewards.

​
Which wallets and cryptocurrencies are supported?

MCC runs on Solana and supports Solana-compatible wallets. USDC on Solana is currently the only supported currency for deposits, withdrawals and gameplay. See Wallets and connection.

​
How do deposits and withdrawals work?

When you deposit, your USDC is held by the on-chain program and recorded in a per-user balance tied to your wallet. When you withdraw, the program transfers funds from that balance back to your wallet, and only a transaction signed by your wallet can do that. The casino operator cannot move your balance. Most transactions confirm within seconds; delays are caused by blockchain conditions, not by MCC. See Deposits and withdrawals.

​
Are there any fees?

MCC charges no deposit or withdrawal fees. Standard Solana transaction fees apply when moving funds on-chain, and each game has a published house edge. See Fees and limits.

​
Can I send USDC to another player?

Yes. You can tip another player straight from your game balance, between 0.1 and 100 USDC, with no fee taken by the casino. Tips cannot be reversed, and they do not count as wagering. See Tipping.

​
How can I contact support?

Email us at [email protected]. You can also report bugs or share suggestions directly from the feedback button in the app.

​
Games

​
Which games are available?

The games currently available are shown in the app. The docs cover each game in detail: Crash, Dice and Mines, with more planned as the platform grows.

​
Are the games provably fair?

Yes. Every outcome is derived from public Solana chain entropy captured when the game’s transaction lands, data nobody can predict or control in advance. Crash and Mines additionally lock in a fingerprint of an operator secret before play and reveal it afterwards, so anyone can verify the outcome was fixed before betting; Dice needs no operator secret at all, its roll is recomputable from public inputs alone. Each game’s exact scheme and a verification walkthrough are in Provably fair.

​
Are there betting limits? What is max profit?

Every game has per-bet stake bounds, currently 1 to 10,000 USDC. On top of that each game enforces a max profit cap sized against the live bankroll: in Crash, if your winnings reach it mid-round the bet is cashed out automatically; in Dice and Mines, a win that would exceed the cap pays the cap. All current values are in Fees & limits; the mechanics are explained in Betting limits and max profit.

​
Do I have to sign every single bet?

No. Turn on Enable play and one free signature authorises a session that places your bets for you, for 24 hours or 7 days. That session can only bet: it can never withdraw or send a tip, and you can disconnect it at any time. See Sessions and devices.

​
Can I play on my phone?

Yes, and you do not need a wallet on it. From the device where your wallet is connected, get a QR code and scan it with your phone. Deposits and withdrawals stay on the device holding your wallet. You can play on 3 devices at once. See Sessions and devices.

​
How does a Crash round work?

Each round has a betting phase, then a multiplier starts climbing from 1.00x. Cash out any time before the crash to win your stake times the multiplier at that moment; you can also set a target multiplier to cash out automatically. See the Crash guide.

​
Network

​
What is a Network?

A Network is a group of players connected through referrals. Players who join with your referral code become part of your Network, and so do the players they invite in turn. An active Network generates referral earnings for its owner. See the Network overview.

​
Where do referral earnings come from?

Every bet generates house edge for the casino (currently 1% of the amount wagered on Crash, 1.5% on Dice and Mines and about 0.3% on Blackjack), and a fixed share of that edge (currently one third) is routed to the referral chain above the player who bet. You receive a slice of it based on where that player sits in your Network. It applies to every settled bet, win or lose: you earn the same whether the players you invited are on a hot streak or a cold one, and the commission is funded from the casino’s margin, never deducted from the player. Inviting players alone earns nothing; earnings come from their wagering. See Layers and commissions.

​
What are Layers, and how are rewards split between them?

Layers are the referral levels of a Network: your direct referrals are Layer 1, their referrals are Layer 2, and so on down to Layer 5. Rewards are weighted toward proximity: currently Layer 1 receives 60% of the pool, then 20%, 10%, 5% and 5% for Layers 2 through 5. See Layers and commissions for the current weights and how they apply.

​
When does a referral become active?

A player counts as an active referral after wagering the qualification threshold in total (currently 20 USDC). Until then, they will not appear as active in your Network. This threshold prevents spam and fake-account abuse. See the qualification threshold.

​
What is a Network NFT?

A Network NFT represents ownership of a Network. Whoever holds the NFT owns the Network and receives the referral earnings it generates. Network NFTs can be bought, sold and transferred like any NFT; the Network’s referral tree stays intact and future earnings go to the new owner. Owning one is not required to play. See Referral codes and NFTs.

​
Can I change or leave a Network after joining?

No. Joining a Network is permanent: the referral link is recorded on-chain and cannot be changed or removed. Choose whose code you use carefully.

​
Security & fairness

​
What does provably fair mean?

It means game results cannot be changed or manipulated after bets are placed, and you don’t have to take anyone’s word for it. Results are generated from a secret committed on-chain before betting plus an unpredictable Solana block hash, and every input needed to re-check a result is published. See Provably fair.

​
How can I verify a game result?

Open the Game Fairness Tool, enter the round’s ID, and the tool fetches the on-chain data, recomputes the result with the same formula the game uses, and confirms it matches. The tool is open source, so you can inspect exactly how the check works, or reproduce it yourself. See Verify a round.

​
Are my funds held by My Crypto Casino?

Your funds are held by the on-chain program, not by the operator. Deposits are recorded in a per-user balance that only a withdrawal signed by your wallet can release. MCC cannot access your wallet, your keys, or move your balance. See On-chain architecture.

​
What happens when a game is paused for maintenance?

Only what is being worked on stops. A pause on one game leaves the others running, along with sign-in, deposits, withdrawals and your profile. A casino-wide window is broader and pauses the cashier too, for as long as it lasts, but it cannot lock your funds: the on-chain program never refuses a withdrawal, so a window can delay one and never prevent it. Rounds already in progress are given time to finish. See Maintenance and game stops.

​
What if I lose a device I was playing on?

Open Profile > Linked devices from any browser signed in with your wallet and disconnect it: it stops playing immediately. Even without that, the exposure is bounded, because a play session can only place bets and can never withdraw. See Sessions and devices.

​
What happens if I lose access to my wallet?

Your MCC account, balance and any Network NFTs are tied to your wallet. If you lose access to the wallet, you lose access to them: there is no account recovery, because there is no custodian who could perform one. Keep your recovery phrase safe and never share it. See Wallet safety.
