Choosing a crypto payment gateway in 2026 means navigating custodial vs non-custodial models, varying fee structures, chain support, and industry restrictions. Here's how the top 10 processors compare on the metrics that matter.
The Landscape
The crypto payment processing market has consolidated around three models: custodial processors that hold merchant funds (CoinsPaid, Alphapo, B2BinPay), general crypto gateways (BitPay, NOWPayments, Coinbase), and non-custodial stablecoin gateways (PYMSTR). Each model has distinct trade-offs.
Custody: Who Holds Your Funds?
- Non-custodial (funds go direct to merchant): PYMSTR, NOWPayments, BoomFi
- Custodial (processor holds funds): CoinsPaid, Alphapo, B2BinPay, Triple-A
- Custodial with escrow option: Coinbase Payments (Base-only)
- Card-based (traditional rails): Nuvei, Worldpay, Paysafe
After $1.8 billion in custodial processor hacks between 2023-2025, custody model is no longer a theoretical concern. It's the primary risk factor.
Fees
- PYMSTR: 1% flat, no hidden fees
- CoinsPaid: 0.5-1.5% + conversion spreads + $25/mo inactivity fee
- BitPay: 2% + $0.25 per transaction
- NOWPayments: 0.5-1%
- B2BinPay: 0.25-0.5% + $1,000 setup fee
- Triple-A: "Contact sales" (opaque)
- Nuvei: 5-8%+ custom high-risk pricing
Crypto Payment Processing Fees Compared (2026)
Headline rates rarely tell the whole story. The all-in cost is what a merchant actually pays once spreads, withdrawal fees, monthly minimums, and setup charges are counted. This is how the leading crypto payment gateways compare on the fee metrics that matter.
| Gateway | Custody | Hidden costs | All-in fee |
|---|---|---|---|
| PYMSTR | Non-custodial | None. No spreads, no reserves, no monthly fees | 1% flat |
| CoinsPaid | Custodial | FX spread 0.3-0.8%, fiat withdrawal 1-3%, $25/mo inactivity | 2-3.5% |
| BitPay | Custodial | Bans iGaming under its AUP; Bitcoin-heavy volume | 2% + $0.25/tx |
| NOWPayments | Non-custodial | Conversion fees on non-USDC payouts | ~1.5-2% |
| B2BinPay | Custodial | $1,000 setup fee, no US merchants | ~1-2% |
What You Pay by Monthly Volume
Percentages stay abstract until you apply them to real volume. Here is the monthly fee a merchant actually pays at common processing volumes, at PYMSTR's 1% flat rate versus custodial crypto gateways and traditional card rails. At $1M a month, the gap between a flat 1% and 5-10% card pricing is $40,000 to $90,000 every month.
| Gateway | $10K/mo | $100K/mo | $500K/mo | $1M/mo |
|---|---|---|---|---|
| PYMSTR (1% flat) | $100 | $1,000 | $5,000 | $10,000 |
| Custodial crypto (2-3.5%) | $200-350 | $2,000-3,500 | $10,000-17,500 | $20,000-35,000 |
| Card processors (5-10%) | $500-1,000 | $5,000-10,000 | $25,000-50,000 | $50,000-100,000 |
iGaming Support
Most processors restrict or prohibit gambling. BitPay explicitly bans iGaming. Coinbase prohibits gambling across all products. B2BinPay is blocked in the US. Only CoinsPaid, Alphapo, and PYMSTR explicitly serve iGaming, and CoinsPaid/Alphapo carry custodial hack risk.
Chain & Token Support
- PYMSTR: USDC + USDT across 5 chains (Ethereum, Base, Polygon, Arbitrum, BNB)
- NOWPayments: 300+ tokens (adds complexity and volatility risk)
- BitPay: Bitcoin-heavy (84% of volume), limited stablecoin support
- Coinbase Payments: USDC only, Base only
- CoinsPaid: Multi-token with conversion spreads
The Bottom Line
For iGaming and high-risk merchants, the choice narrows quickly. You need: non-custodial architecture (to avoid hack risk), iGaming support (most processors ban it), transparent pricing (no hidden spreads), and stablecoin focus (no volatility). PYMSTR is the only processor that checks all four boxes.
