Best Crypto Payment Gateways for Merchants (2026 Comparison)
Choosing a crypto payment gateway comes down to three questions: which settlement networks it supports, how much of every transaction you keep after fees, and how quickly your engineers can ship it. Below we compare VaultraC2B, CoinGate, and NOWPayments against those three concerns.
At-a-glance comparison
| Gateway | Networks | Merchant fee | Best for |
|---|---|---|---|
| VaultraC2B | USDT TRC20, USDT ERC20, bank, card | From 0.5% | Corporate multi-rail collection + USDT payout |
| CoinGate | BTC, ETH, USDT, 70+ assets | ~1% | E-commerce plug-ins (Shopify, WooCommerce) |
| NOWPayments | 200+ assets, auto-conversion | 0.4%–0.5% | High-volume crypto-native businesses |
Settlement networks (TRC20 vs ERC20)
Most merchant volume today settles in USDT. The network you settle on drives your effective cost: TRC20 typically costs cents per transfer and confirms in seconds, while ERC20 is more expensive during Ethereum congestion but is the only option many institutional counterparties accept. A gateway that supports both — like VaultraC2B — lets you route payouts by counterparty preference instead of forcing every merchant onto one chain.
Transaction fees
Advertised percentages rarely tell the whole story. Look for gateways that separate processing fee (what the gateway keeps), network fee (what miners/validators keep), and FX spread (what you lose converting fiat to crypto or back). VaultraC2B exposes gross, fee, and net on every transaction and supports per-client fee overrides, so you can price enterprise accounts differently from long-tail merchants without a spreadsheet.
Ease of integration
CoinGate and NOWPayments are strong if you sell through Shopify or WooCommerce and need a drop-in plugin. VaultraC2B is designed for the opposite case: a finance team that wants to issue branded payment links, upload KYC documents per counterparty, and approve USDT payouts inline — no separate treasury tool.
Which gateway should you choose?
- Corporate client with mixed rails: VaultraC2B — bank transfer, card, and crypto in one balance, with USDT payouts.
- E-commerce checkout: CoinGate — mature Shopify/Woo integration and 70+ supported assets.
