Web3 · Service Crypto payment gateway development
Crypto payment gateways for merchants and platforms: stablecoin checkout, payment links, confirmations, webhooks, refunds, settlement and accounting exports.
In short
A crypto payment gateway lets a business accept payments in cryptocurrency — today mostly stablecoins such as USDC and USDT — much as a card gateway accepts cards. It creates a payment request, watches the blockchain for the matching transaction, confirms it, notifies the merchant, and handles refunds, settlement and reporting.

Signs this is the right service
- Customers want to pay in stablecoins or crypto.
- You pay or collect across borders and card or wire fees are high.
- Your platform needs to accept payments on behalf of many merchants.
- Crypto payments arrive today, but reconciling them is manual.
What you get
Checkout
Hosted checkout, payment links and in-app payments with clear amounts, networks and expiry.
Payment detection
Unique addresses or references per payment, chain monitoring and confirmation rules per network.
Merchant integration
Webhooks, an API and plugins so merchants know the moment a payment is final.
Refunds and edge cases
Under- and over-payments, wrong networks and late payments handled as real states with refunds.
Settlement and accounting
Settlement to merchants in crypto or, through licensed partners, fiat — with exports for accounting.

Crypto payment gateways: common questions
Why stablecoins rather than other crypto?
- Stablecoins hold a steady value, so neither customer nor merchant carries price risk between payment and settlement.
Can merchants receive local currency?
- Yes, by converting through licensed off-ramp partners and settling to the merchant's bank account.
How do refunds work with crypto?
- Blockchain payments cannot be reversed, so refunds are new payments back to the customer — which the gateway tracks against the original order.
Which networks should we support?
- Those where your customers already hold stablecoins and fees are low — commonly Ethereum layer-2 networks and a few other major chains.
