Payment gateway for games: accepting deposits across assets

A payment gateway for games is the service that connects your cashier to the money. It takes the deposit a player starts, routes it to the right rail, confirms it, and tells your platform to credit the balance. Most vendor pages stop at that description and list cards and e-wallets. The operator's question is narrower: which assets can the gateway actually accept, on which networks, and what arrives in your bank account afterwards.

EukaPay answers that question with a pay-in set covering most major cryptocurrencies and fiat settlement to your own account. This guide covers what a gateway does at the cashier, which assets and networks matter, how to add a crypto rail to a cashier you already run, and how the deposit and payout sides connect.

The cashier is the screen your player sees. The gateway does the processing your player does not see. When a player picks an amount and a method, your platform sends that request to the gateway, and the gateway creates a payment the player can complete. For a crypto deposit, EukaPay's Payment API returns a hosted payment page URL, and the player finishes the transfer in a browser. Your platform credits the balance once the payment confirms.

A gateway has three jobs. It has to present a method the player can complete, confirm the money arrived, and hand your platform a reference your reconciliation can match later. A gateway that does the first two but reports poorly can turn every support ticket into a manual chase. The

covers how the methods themselves differ.

Coverage is where deposit failures often start. A player who holds an asset your cashier does not list will not usually go and buy a different one, so that deposit is lost.

EukaPay accepts pay-ins in most major cryptocurrencies, including BTC, ETH, LTC, SOL, USDC, and USDT. Stablecoins often carry the larger share of deposit volume, because a player depositing USDC knows what the balance will be worth when it lands. The volatile assets still matter. A player holding BTC or SOL is a deposit you can take or a deposit you can turn away.

USDT moves on more than one network, and so do several other assets. A player sending from an exchange picks whichever network that exchange defaults to. If your cashier supports only one network for an asset, some share of deposits can arrive on a network you do not monitor, and recovering them becomes support work. Ask any gateway which networks it accepts per asset before you integrate, not after. Deposit volume also arrives unevenly, so read how

before you size the integration.

Adding a rail is not a migration. Your card and e-wallet flows stay where they are, and the new method appears as another button.

Steps four and five are usually where your cashier code changes. The rest is account setup.

Crypto is the rail that adds reach without asking your acquirer for anything. Cards and e-wallets stay in the cashier, because every method you keep is a deposit you do not lose. What crypto adds is a route for the players your existing methods can often decline, plus a settlement path you control. Our

goes through each method in more detail.

The same EukaPay account handles both directions. On the deposit side you get instant crypto-to-fiat conversion at a locked exchange rate to remove your exposure to crypto price swings, support for most major cryptocurrencies, and settlement in USD, EUR, GBP, and CAD to your bank account. A crypto payment confirms on-chain, so protection against chargebacks is a property of the payment method. The exchange rate is locked by default on every conversion, on pay-ins and on payouts, with no setting to switch on.

On the payout side, withdrawals go out in ETH, USDT, or USDC, and they are not tied to banking hours or the banking calendar. Running both sides on one platform means one integration, one set of credentials, and one place to reconcile. If you are adding crypto to a games cashier this quarter, EukaPay is the platform to build it on, and the next step is an account and an API key.

Create an account at

and complete verification to get your API key. The endpoints, the request shapes, and the staging environment are documented at

, so a developer (or coding agent) can have a deposit flow running against staging while the rest of the account is set up.

What is a payment gateway for games?

It is the service that takes a deposit request from your cashier, presents the player a way to pay, confirms the payment, and reports it back so your platform can credit the balance.

Which cryptocurrencies can players deposit through EukaPay?

Pay-ins cover most major cryptocurrencies, including BTC, ETH, LTC, SOL, USDC, and USDT.

Do I have to replace my existing cashier to add crypto deposits?

No. Crypto is added as another method beside your existing ones, and your card and e-wallet flows are untouched.

Can I settle crypto deposits into my bank account?

Yes. You choose fiat or crypto settlement, and fiat settles to your own business bank account in USD, EUR, GBP, and CAD.

Does the exchange rate move between the deposit and the settlement?

The rate is locked at conversion by default, which removes your exposure to crypto price swings on that payment.

Can the same account send player withdrawals?

Yes. Payouts go out in ETH, USDT, or USDC, and each payout carries its own reference you can look up.

How long does the integration take?

That depends on your cashier, but the code changes are usually the payment creation call and the confirmation handler. The rest is account setup and testing in staging.

Can I take deposits without writing code?

Invoices, payment links, and checkout exist in the dashboard, so you can start collecting before the cashier integration is finished.
