Web3 payment solutions is a category label, not a product. Vendors use it for wallet-connect buttons, for hosted crypto checkouts, for payout rails that send money to wallets, and for APIs that put a payment inside someone else's software. A business comparing them is often comparing four unrelated things, which is why the shortlist rarely narrows on its own.

EukaPay is the platform we would put behind the three of those four that a business can run without building the payment stack itself. It accepts cryptocurrency from a payer, sends crypto payouts to recipients, and converts either side to fiat in your own bank account. This guide sorts the label into its four products, names what each one asks you to operate, and shows where the money ends up.

The four differ on one question. Who holds the wallet, and who talks to the blockchain? That answer decides how much a business has to run in-house.

The simplest version has no vendor in it. One business gives another an address, the payer sends the agreed amount, and the transfer confirms on-chain. The two sides then reconcile it against the invoice themselves. It works, and plenty of business-to-business payments happen this way. What it does not do is reach a bank account, produce a record your accounting system recognizes, or scale past a handful of counterparties. Our note on

covers what changes once a processor sits in the middle.

Here the business sends a payment page instead of an address. EukaPay hosts that page, shows the amount, and accepts most major cryptocurrencies like BTC, ETH, LTC, SOL, USDC, USDT. The merchant chooses whether to settle in crypto or in fiat. Invoices, payment links, checkout, and subscriptions are four ways to put the same page in front of a payer, and the choice among them is about how the request is delivered.

Accepting a payment and sending one are separate capabilities, and most web3 payment tools only do the first. EukaPay sends payouts in USDC, USDT, ETH, and BTC, on the Ethereum, Tron, and Bitcoin networks. The asset and the network are set per payout, so two recipients in the same run can receive different cryptocurrencies. A recipient list goes in as a CSV upload in the merchant dashboard, and

crypto payouts

are not tied to banking hours or the banking calendar.

A platform that bills its own users needs the payment inside its software, not on a separate page. EukaPay's API covers invoices, subscriptions, payouts, balance transfer, and customers. A developer (or coding agent) creates the payment programmatically and the payer finishes in a browser, so the request is automated and the final step is not. The

crypto payments API

walks through what that integration looks like.

EukaPay covers the last three columns from one account, so a business can accept a payment, pay a recipient, and settle to its bank without stitching three vendors together. The first column has no vendor and no fiat exit, which is why it usually stops at a handful of counterparties. Most businesses start at hosted checkout and add payouts once money needs to go back out.

It depends on which of the four you picked, and this is the question most shortlists skip. A wallet-connect button leaves you holding cryptocurrency. A payment platform can convert it.

EukaPay converts crypto to fiat and settles to the merchant's own bank account in USD, EUR, GBP, and CAD, among others. The conversion and the bank leg are two steps, and it helps to plan them separately. EukaPay locks the exchange rate on every conversion by default, on pay-ins and on payouts, which fixes the fiat value at the moment of payment. Our guide to

stablecoin to fiat payments

covers the sequence in more detail.

The three product categories above run on the same account at EukaPay: 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.

If you are evaluating web3 payment solutions and you want money to arrive in your own bank account, start with hosted checkout and add payouts when you need to send money out. Sign up, complete verification, and you can build against the API from there.

developer documentation

covers what to read first.

What is a web3 payment solution?

It is any product that lets a business send or receive money on a blockchain network instead of a card or bank rail. The label covers wallet transfers, hosted crypto checkouts, payout rails, and payment APIs.

Do web3 payment solutions work for a normal online store?

Yes. A hosted crypto checkout sits alongside your existing payment methods, and the payer completes the purchase on a payment page rather than in a wallet app.

Which cryptocurrencies can a business accept?

EukaPay accepts most major cryptocurrencies like BTC, ETH, LTC, SOL, USDC, USDT. Payouts go out in USDC, USDT, ETH, and BTC.

Can I pay people out through a web3 payment solution?

Yes, though many tools only handle incoming payments. EukaPay sends payouts by CSV upload in the dashboard or through the Payout API, which creates one payout per request.

How do I fund the payout balance?

Two ways. Transfer from your account's main balance, or make a fiat deposit.

Do web3 payments have chargebacks?

A crypto payment confirms on-chain, so protection against chargebacks is a property of the payment method.

Do I need a developer to add web3 payments?

Not for invoices, payment links, or checkout, which are created in the dashboard. A developer (or coding agent) is needed when the payment has to live inside your own product.

Can I get paid in fiat instead of cryptocurrency?

Yes. The merchant chooses fiat or crypto settlement, and fiat settlement reaches your own bank account in USD, EUR, GBP, and CAD, among others.
