Duel Deposit Confirmation Times by Network
How long deposits take to credit on each blockchain, why confirmation requirements exist, and what actually controls the wait.
On this pageShowHide
Quick answer
Deposit speed has almost nothing to do with the casino and almost everything to do with the chain you chose. Understanding the two variables involved — block time and required confirmations — explains every wait you will experience.
The two numbers that decide the wait
Block time is how often the network produces a block. Confirmation requirement is how many blocks the platform waits for before crediting.
Multiply them and you have your approximate wait, assuming your transaction gets into the next block.
Worked example
- Chain block time
- 10 minutes (Bitcoin)
- Confirmations required
- 2
- Expected wait
- Roughly 20 minutes, once included in a block
- Plus mempool wait
- Zero if your fee is competitive; hours if it is not
Typical times by network
| Network | Block time | Typical credit time | Notes |
|---|---|---|---|
| Solana | Sub-second | Seconds to ~1 min | Fastest common option |
| Tron (TRC-20) | ~3 seconds | Under a minute | Very low fees |
| Base / Arbitrum / Optimism | ~2 seconds | 1–3 minutes | Layer-2 rollups |
| Polygon | ~2 seconds | 1–3 minutes | Low fees |
| BNB Chain | ~3 seconds | 1–2 minutes | Low fees |
| Ethereum (ERC-20) | ~12 seconds | 2–10 minutes | Fee-sensitive |
| Litecoin | ~2.5 minutes | 5–20 minutes | Moderate fees |
| Bitcoin | ~10 minutes | 10 min – 2+ hours | Highly fee-sensitive |
Where the time actually goes
Step 1
Mempool wait
Fee dependent — 0 to hours
Step 2
Block inclusion
One block time
Step 3
Confirmations
N × block time
Step 4
Platform credit
Usually seconds
The variable stage is the first. On Solana or Tron the mempool wait is effectively zero. On Bitcoin during congestion, an underpriced transaction can sit there for hours before it is even considered for a block.
Why fees affect speed on some chains and not others
Fee-market chains auction limited block space. Bid high and you are included immediately; bid low and you wait for demand to drop.
| Chain type | Fee behaviour | Effect on you |
|---|---|---|
| Bitcoin, Ethereum | Competitive auction | Low fee equals long wait |
| Solana, Tron, most L2s | Cheap and abundant space | Fee is essentially irrelevant to speed |
If you deliberately chose the lowest fee your wallet offered, expect a slow deposit on a fee-market chain. See gas fees and network costs.
Choosing for speed
- Prefer Solana, Tron or a layer-2 for routine deposits you want available quickly
- Reserve Bitcoin for larger, non-urgent transfers where the fee is proportionally small
- Let your wallet pick a market-rate fee rather than the minimum, on fee-market chains
- Deposit before you plan to play, so confirmation time is never a problem
When a wait becomes a problem
Escalate if the transaction is fully confirmed on the explorer beyond the required count and the balance has not updated within about an hour. Until then, waiting is the correct action. Diagnosis: deposit pending; if it is confirmed but absent, deposit not showing up.
Confirmations, briefly
A confirmation is simply another block built on top of the one containing your transaction. Each additional block makes reversing the history exponentially more expensive, which is why the requirement exists at all. Deeper explanation: blockchain confirmations explained.
Summary
Your wait equals mempool time plus block time multiplied by the required confirmations. Fast chains credit in under a minute; Bitcoin is the slowest common option and the most sensitive to the fee you set. Choose the network deliberately, let your wallet use a market-rate fee on fee-market chains, and deposit ahead of when you intend to play.
