Crypto gambling glossary
The crypto-casino world mixes gambling and blockchain jargon. Here are the terms that actually matter, in plain English.
On-chain & solvency terms
Proof of reserves — verifiable on-chain wallet balances showing what an operator holds (explainer). Hot wallet — the operator's online wallet that processes deposits/withdrawals. Cold wallet — offline storage for reserves. On-chain volume — value moved through an operator's wallets; only meaningful when internal churn and wash/treasury flow are excluded (which is why most trackers overstate it).
Fairness & game terms
Provably fair — a cryptographic scheme letting you verify a game outcome wasn't manipulated (explainer). RTP (return to player) — the % of wagers a game pays back over time. House edge — the casino's built-in mathematical advantage (100% − RTP). RNG — random number generator behind game outcomes.
Money & bonus terms
Wagering requirement — how many times a bonus must be bet before withdrawal (explainer). Rakeback / cashback — a % of wagers or losses returned. Sticky bonus — a play-only bonus removed when you withdraw. Max cashout — a cap on winnings withdrawable from a bonus. Stablecoin — a dollar-pegged crypto (USDT, USDC) that's the dominant casino deposit currency. TRC20 / ERC20 — the Tron and Ethereum token standards USDT runs on; TRC20 is cheaper and faster.
Network & wallet terms
Block explorer — a public website (Etherscan, Tronscan, Solscan) for reading any address's balance and transactions. Confirmation — a block that includes your transaction; casinos wait for a number of them before crediting. Gas / network fee — the cost to send a transaction; tiny on Tron/Solana, variable on Ethereum. Memo / destination tag — an identifier some deposits require; omitting it can strand funds. Wallet cluster — a group of addresses inferred to share one owner via common-input-ownership, the basis of attribution.
Market & risk terms
Net flow — deposits minus withdrawals over a window; balanced two-way flow is healthier than one-way (report). Coverage level — how complete our wallet mapping is for a brand; a reserve figure at low coverage is a floor, not a total. Wash trading — fake volume from addresses cycling funds to inflate activity. Exit scam — an operator vanishing with player funds; see neutral on-chain distress signals. KYC — identity verification, often required before large withdrawals.
FAQ
They are two sides of the same number: RTP (return to player) is the percentage of wagers a game pays back over time; the house edge is the casino's advantage, equal to 100% minus the RTP. A 97% RTP game has a 3% house edge.
TRC20 is the Tron token standard that USDT (Tether) runs on. USDT-TRC20 is the most popular casino deposit rail because it is fast (seconds) and cheap (cents or free), unlike USDT-ERC20 on Ethereum which costs more in gas.
Methodology & disclaimer. Figures are derived from on-chain transfers attributed to wallets we associate with each operator, plus third-party ratings shown with their source. Blockchain attribution carries inherent uncertainty, and reserves are an all-chain best-effort estimate from mapped wallets — coverage varies by operator. These pages describe observed activity and third-party data only; they are not an endorsement of any operator and not a statement on any operator's solvency, legality, fairness, or safety, and nothing here is financial, legal or investment advice.
