Questions, answered directly
The questions readers ask most about the settlement layer, each answered in a sentence or two and tied to the page that explains it in full.
Block 01Depth and credit
How many confirmations does a crypto deposit need before it is credited?
It depends on the asset, the network and the operator, and there is no universal number. A confirmation is one block on top of the block that included your transaction, and each new block adds one. An operator picks a threshold — often a small number for a fast, hard-to-rewrite chain and a larger number for a chain where blocks are cheap to produce — and credits the balance only once the deposit reaches it. The threshold is a policy choice by the operator to manage the risk that the block is later removed, not a property of the coin itself, which is why the same asset can be credited at different depths on two different sites.
What actually happens between pressing send and seeing the balance?
Your wallet signs a transaction and broadcasts it to the network, where it waits in the mempool — the pool of transactions not yet in a block. A miner or validator then includes it in a block, which gives it one confirmation. Each subsequent block adds one more, and when the deposit reaches the operator threshold the balance is credited. The funds are on the ledger the moment the block is final enough; the credit is a separate, later decision by the operator. A transaction can sit in the mempool for a while if the fee offered is low and the network is busy, and it can even be dropped.
Does a bigger deposit get credited faster?
Sometimes it is the other way around. Some operators require more confirmations, not fewer, for larger deposits, because the value at risk during a reorg is higher. Others credit small amounts at a shallow depth and hold large ones for review. The confirmation threshold and any manual review are both policy decisions the operator makes, and a deposit that clears a threshold can still be held separately by a screening or compliance check. Depth of confirmations and a compliance hold are two different gates, and a deposit can pass one and wait at the other.
Block 02Reorgs and finality
What is a chain reorganisation, and can it undo a deposit?
A reorganisation, or reorg, happens when the network abandons one chain of blocks in favour of another that carries more accumulated work. The transactions in the abandoned blocks are not destroyed — they usually return to the mempool and are re-included in the new chain — but for a short window the picture of which transactions are confirmed can change. This is exactly the risk a confirmation threshold is designed to absorb: the deeper a block sits, the more work an attacker would need to reproduce to replace it, so requiring several confirmations makes a reversal progressively more expensive and therefore less likely.
Is finality absolute once enough confirmations have passed?
Not absolutely — finality is a matter of probability, not impossibility. Every additional confirmation makes a reversal require more work than the honest chain has already accumulated, which for a well-distributed network quickly becomes impractical, but a sufficiently powerful adversary could in theory rewrite even a deep history. In practice operators, exchanges and courts treat a set depth as settled, and some modern chains add an explicit finality mechanism on top of depth. The honest way to hold it is that confirmations make reversal economically and practically infeasible, not logically impossible.
Block 03Screening and identity
Why does the casino screen my deposit address?
Most operators use blockchain-analytics tools that score addresses by the history attached to them, and many are also required to screen against sanctions lists. A deposit that arrives from an address associated with theft, a sanctioned entity or mixing can be flagged, held for review, or in some cases refused and returned. Screening looks at the source of the funds, not at who you are, though a hold often triggers an identity check as well. It is worth knowing that the address you send from can carry a history you did not create, and that a screening hold is a compliance action rather than a normal withdrawal delay.
Block 04Fees, memos and habits
Who charges the fee on a crypto withdrawal — the network or the operator?
There can be two. The network fee is paid to the miners or validators who include your transaction in a block; it rises and falls with how busy the network is and how quickly you want it confirmed. The operator fee is what the casino itself charges to process the payout, if it charges one at all. A withdrawal quote should separate the two: the amount debited, the operator fee, the network fee and the amount that actually lands at your address. A single "fee" figure that does not say who receives it hides the fact that one part goes to the network and one to the operator.
What is a memo or destination tag, and what if I omit it?
Some networks send many users' deposits to one shared address and use a memo, tag or destination field to say which user a payment belongs to. That short string — a destination tag on one chain, a memo on another — is what attributes the deposit to your account. If you omit it, the funds still arrive at the operator's address on the ledger, but the operator cannot tell whose deposit it is, and recovering it means opening a support case and proving the transfer was yours. It is one of the few crypto mistakes that is routinely recoverable, but only slowly and only with the tag you should have entered.
Why can a crypto transfer not be reversed?
Because a settlement on a public ledger is final by design. There is no central party that can claw back a confirmed transfer the way a card issuer can charge back a payment. Once a transaction is included in a sufficiently deep block, the only way to undo it is for the sender's own key to sign a new transaction back to you, and an anonymous sender has no reason to. This is the reason a wrong address, a mistyped network or a payment to a scam address is usually permanent loss: the ledger recorded a valid transfer to a destination you cannot control.
What is the single most useful habit when moving money on-chain?
Match three things before you send: the address, the network and, if the destination requires one, the memo or tag. The address must be copied whole and, where possible, verified character by character at both ends; the network must be the one the receiving party supports, because the same asset on a different chain is a different ledger; and a destination that asks for a memo must receive it. Almost every permanent on-chain loss comes from one of those three being wrong, and none of them can be undone after the transaction is confirmed.
Affiliate disclosure and risk warning
Every affiliate link on this page and in the header is a sponsored link to a partner operator, and we may be paid if you open an account through it, at no extra cost to you. That link pays us; it does not make a transfer safer, it does not improve any decision, and it is never a recommendation to play or to move money. Nothing on this page is legal, financial or investment advice, and nothing here is a view on any coin, token or network. 18+ only. Gambling is a real risk of real loss, and a crypto transfer is a real transfer: it settles on a public ledger where there is no chargeback, no reversal and usually no way to recover funds sent to a wrong address or the wrong network. A deposit you make is not a bet, but it becomes money at risk the moment it is credited, and the price of the asset you hold can fall — sometimes to nothing — while it sits there. The mechanics explained here — how many confirmations a deposit needs, what a chain reorganisation can undo, why an address is screened, which fee belongs to the network and which to the operator, why a memo field matters and why finality is a probability rather than a guarantee — belong to the networks and the operators, not to any suggestion that you should use them. The rules that govern these products — whether crypto is accepted at all, which assets and networks are supported, whether the operator is licensed, what is owed on winnings, how deposits are screened and whether any of it is lawful for you — differ between countries, states and provinces, they change, and they depend on facts about you that a website cannot know. Nothing on this page is advice, a prediction or a valuation of any asset. Never stake money you cannot afford to lose, never borrow to play, and never chase losses with a larger stake. Gambling can cause serious financial harm, including debt and damage to relationships and mental health. Free and confidential support is available in most countries through national gambling-harm helplines, for players and for the people around them.
