A deposit here is not a payment but a transfer between two wallets, and the difference is not verbal. A conventional payment tolerates error because it can be disputed and reversed; an on-chain transfer cannot. This page is therefore built around two decisions — which coin and which network — because everything else is detail, and these two alone cannot be corrected after execution.
The transfer sequence from wallet to balance
- Have the coin available A digital balance must already sit in an external wallet or on an exchange. There is no way to fund the account directly from a bank balance.
- Open the wallet page inside the account select deposit, then choose the coin from the list.
- Select the network and here lies the decisive choice. Some coins run on more than one network, each with an entirely different address.
- Copy the address using the copy control or by scanning the QR code. Typing by hand is never acceptable: a single wrong character sends the money to a destination nobody owns.
- Execute from the external wallet pasting the address and confirming the network name matches on both screens before sending.
- Wait for confirmations The balance credits once the required confirmation count is reached, taking anywhere from seconds to tens of minutes depending on coin and congestion.
The error with no remedy: a network mismatch. Sending USDT over ERC20 to an address designated for TRC20 produces no error message and returns nothing. The funds arrive at an address that is technically valid on a different network and pass beyond the reach of both parties. Neither the platform nor the provider nor any other body has the authority to reverse the transfer. The only two effective measures: match the network name literally before confirming, and run a small test transfer when using a coin or network for the first time.
Sixteen coins and 23 rails: which suits small amounts?
Supported coins per the official wallet source verified in August 2026: BTC, BCH, ETH, LTC, USDT, USDC, SOL, BNB, XRP, DOGE, TRX, ADA, LINK, AVAX, HBAR and GRAM.
The ordering below is not by coin popularity but by what actually matters: how much of the amount survives network fees, and how long arrival takes.
| Coin | Network | Fees | Confirmation speed | Suits amounts |
|---|---|---|---|---|
| SOL | Solana | Very low | Seconds | Small and large |
| TRX | Tron | Very low | Seconds | Small and large |
| XRP | XRP Ledger | Very low | Seconds | Small and large |
| USDT · USDC | TRC20 | Very low | Seconds to a minute | Small and large |
| LTC · DOGE | Native networks | Low | Minutes | Small and large |
| BNB · ADA · AVAX · LINK · HBAR · BCH · GRAM | Native networks | Low to moderate | Seconds to minutes | Medium and large |
| BTC | Bitcoin | Varies with congestion | Tens of minutes | Large |
| USDT · USDC | ERC20 | High and volatile | Minutes | Large only |
| ETH | Ethereum | High and volatile | Minutes | Large only |
The simple arithmetic: a network fee of a few dollars on a ten-dollar deposit consumes a tenth of it or more, while becoming marginal on a thousand-dollar deposit. The optimal choice therefore shifts with the amount rather than with a preference for a coin. Stablecoins such as USDT and USDC add a third benefit independent of fees and speed: they neutralise exchange rate movement between the moment of deposit and the moment of payout, which matters for anyone intending to leave a balance in the account.
The alternative route for those holding no cryptocurrency
The site provides a route through a specialist external provider accepting Visa and Mastercard alongside local methods in some markets such as Apple Pay, Pix and Blik. But describing what actually happens to the money is necessary before using it.
| Common assumption | The reality |
|---|---|
| "A fiat deposit by card" | Buying cryptocurrency and then transferring it; the resulting balance is digital and later withdrawals are made in crypto, not back to the card |
| "Fee-free deposit" | True for the direct crypto transfer only; the card route carries a processing fee from the external provider |
| "The transaction happens on the site" | The provider is a third party, and any refusal occurs there or at the bank rather than at the platform |
Many banks refuse cryptocurrency purchases or gambling-related transactions based on merchant category codes. In jurisdictions prohibiting the activity, the refusal occurs at the payment service provider level and cannot be circumvented by the player through any setting.
What you actually pay: platform fees against network fees
| Item | Value | Who charges it | Note |
|---|---|---|---|
| Minimum deposit | $5 | The platform | The same limit applies to withdrawals |
| Maximum deposit | None | — | Passing €5,000 cumulatively triggers mandatory verification |
| Deposit fees | None | The platform | — |
| Network fees | Always present | The blockchain network | Borne by the sender in every case |
| Card purchase fees | Processing fee | External provider | Outside the platform's control |
| Time to credit | Seconds to tens of minutes | The network | Depends on coin and congestion |
The Kuwaiti dinar and KNET: why neither exists here
The question recurs often enough to deserve a direct answer, and the reason has two independent layers.
The first layer — platform structure. There are no fiat balances in any national currency, no bank accounts for players, and no arrangements with local banks or national payment networks such as KNET. There is simply no destination a dinar transfer could reach, even if both parties wanted one.
The second layer — the payment path. In countries prohibiting gambling, Kuwait among them, national payment networks and banks do not process this class of transaction. That barrier sits well upstream of the platform, at the bank and payment service provider, and has nothing to do with the casino.
Any party offering a "deposit in Kuwaiti dinars" or "payment via KNET" at Duel is offering a service that does not exist. Such offers typically appear on domains impersonating the brand or through unofficial intermediaries, and funds sent through them reach no gaming account.
A transfer that never appeared: three diagnostic steps
- Check the transaction status on-chain by copying the transaction identifier from the sending wallet and inspecting it in the relevant blockchain explorer. If it is pending, the issue is network congestion rather than a fault at the platform, and there is no need to contact support yet.
- Match address and network by comparing the destination address in the transaction against the one shown on the deposit page and confirming the networks match. A mismatch is the most common cause, and the only one that cannot be remedied.
- Contact support with a complete message including the transaction identifier, network name, coin, amount, time of sending and username. A complete message is resolved on the first reply; an incomplete one consumes two extra rounds. Live chat is available around the clock with a median response near a minute, and email at around two hours.
