How many confirmations a deposit needs
A deposit is credited only once it is buried under enough blocks — but the number is a policy choice, not a rule the network hands down. This page explains what a confirmation is, why the threshold differs by chain and operator, and why a confirmed deposit can still wait at a second gate.
Block 01What a confirmation is
A confirmation is one block on top of the block that included your transaction. When a miner or validator first places your transaction in a block, it has one confirmation; each new block appended after it adds one more. Nothing about the transaction changes as depth grows — the same transaction, the same amount — only the cost of removing it rises. A confirmation is therefore a measure of how expensive your transaction is to undo, not a certificate that it can never be undone.
Block 02Why the threshold varies by chain and operator
Two facts drive every threshold. The first is how expensive a block is to produce on that chain: where producing a competing block is cheap and fast, a shallow confirmation is worth less, and operators wait for more. The second is the operator's own risk appetite and the size of the deposit: a large transfer may be held to a deeper threshold than a small one, because more value is at stake during the window a reorg is possible.
| Factor | Pushes it lower | Pushes it higher |
|---|---|---|
| Reorg cost | Expensive to produce blocks | Cheap or fast block production |
| Deposit size | Small amounts | Large amounts at risk |
| Network finality | An explicit finality rule | Probabilistic-only depth |
| Operator policy | Fast-credit product | Conservative treasury |
This is why the same coin can take minutes to credit on one site and feel nearly instant on another. Neither is wrong; each operator set its threshold where the risk it carried felt acceptable against the friction it imposed.
Block 03A worked depth ladder
Suppose an operator credits a deposit at three confirmations and blocks on the network arrive on average every so often. The three stages below show what the balance does as depth grows. The numbers are illustrative; the structure — waiting, then crediting, then settling — is what matters.
| Stage | Confirmations | Balance state |
|---|---|---|
| Broadcast | 0 | Not credited |
| First block | 1 | Still not credited |
| Two blocks | 2 | Still not credited |
| Three blocks | 3 | Credited |
| Deeper | 6+ | Settled in practice |
Note that the transaction existed on the ledger from the first block onward; only the credit was withheld. If the network stalled after block two, the funds would be in a block and still not in the balance — the ledger and the operator are that far apart.
Block 04Two different gates: depth and compliance
A credited deposit has passed the depth gate. It may still be waiting at a compliance gate — address screening, sanctions checks or a manual review — which is a separate process with a separate trigger. Depth is about time; screening is about the history attached to the sending address and any regulatory obligation the operator carries. A deposit can clear one and hold at the other, and the two look identical from outside the account.
Once confirmed, the money is mine.
Depth is one gate; a screening or review hold is another, and it can apply after depth is reached.
What screening looks at
Screening scores the sending address by its history and checks it against sanctions lists. It is a compliance action, not a delay.
Block 05Why a deposit looks stuck
A deposit that has not been credited is usually in one of four places, and they are told apart by looking at the ledger rather than the balance. The transaction may not yet be in a block; it may be in a block but below the threshold; it may have reached the threshold and be held by screening; or it may have been sent on the wrong network entirely, in which case it is not late at all but lost.
Block 06A confirmations checklist
Confirmations read cleanly when the deposit is treated as a sequence with a check at each step.
- Find the transaction Is it in a block yet, or still in the mempool?
- Count the depth How many confirmations does it have against the operator threshold?
- Separate the gates Is the wait depth, or a screening hold that depth cannot clear?
- Check the network Is the asset on the network the destination address actually supports?
Reorganisations
Why a shallow block can be removed, and how depth is the operator's protection against it.
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.
