A **crypto payment gateway** is the infrastructure that lets a business accept cryptocurrency at checkout — the way Stripe or PayPal lets you accept cards. It generates a payment address or invoice, watches the blockchain for the incoming transaction, confirms it, and then notifies your application that the order is paid. ## Why merchants are adding crypto checkout in 2026 - **180+ countries served by one rail.** Crypto does not care about local banking hours or correspondent banks. - **Lower fees on settled volume.** Most gateways land between 0.4% and 1% — well below the 2.9% + 30¢ of card networks. - **No chargebacks.** Once a blockchain transaction confirms, it is final. Disputes become refund workflows you control. - **Stablecoin demand.** USDT and USDC volumes now dwarf BTC at checkout; merchants can settle in dollars without ever touching a bank. ## How a crypto payment gateway works 1. **Checkout** — The shopper picks a coin and amount. The gateway locks the FX rate for a short window (usually 10–15 minutes). 2. **Address generation** — A unique deposit address or invoice is created for that order. 3. **Blockchain watch** — The gateway monitors the relevant chains for the expected amount. 4. **Confirmation** — Once enough confirmations land, the order is marked paid. 5. **Webhook** — Your backend gets a signed callback so you can fulfil the order. 6. **Settlement / payout** — You either keep the crypto, auto-convert to a stablecoin, or pay out to another wallet. ## What to look for in a gateway - **Coin coverage.** A modern gateway should support 100+ assets across BTC, EVM chains, Tron, Solana and L2s. - **Hosted checkout + API.** A no-code link for the long tail, a clean REST API for production. - **Settlement options.** Crypto, stablecoin, or auto-conversion. - **Operator tooling.** Mass payouts, refunds, dispute workflows, reconciliation reports. - **Compliance.** KYB onboarding, country restrictions, risk rules, audit logs. ## Where Xynex fits [Xynex](/) is a crypto payment gateway built for operators — 360+ assets, hosted checkout, mass payouts, crypto subscriptions, and a full admin console out of the box.
