Most iGaming crypto processors — Alphapo, CoinsPaid, NOWPayments, Cryptomus — are custodial and take a percentage of every transaction. Coinflux is non-custodial and flat monthly. Here’s the side-by-side.
| Coinflux | Alphapo | CoinsPaid | NOWPayments | Cryptomus | |
|---|---|---|---|---|---|
| Custody model | Non-custodial | Custodial | Custodial | Custodial | Custodial |
| Holds your funds | No — never | Yes | Yes | Yes | Yes |
| Pricing model | Flat monthly | % per transaction | % per transaction | % per transaction | % per transaction |
| Transaction fee | 0% | 1% + $0.25 | ~0.8% | 0.3–0.5% | 0.4–2% |
| Monthly cost | $71–$242 flat | Negotiated | None | None | None |
| Double-credit protection | Idempotent ledger | Not documented | Not documented | Not documented | Not documented |
| Built for iGaming | Yes | Yes | Yes | General | General |
Competitor fees are their publicly listed rates (2026) and vary by volume; verify current terms with each provider.
A percentage fee looks small until you run volume. At $1,000,000/month, a 0.8% processor costs ~$8,000/month. Coinflux’s Growth plan is $242 flat — the same infrastructure, without a tax on every deposit. The more you process, the wider the gap.
Custody is the other half. Custodial processors hold your funds in hot wallets — convenient until they’re drained. Alphapo, a custodial gateway, lost roughly $60M to a hot-wallet hack in 2023. Coinflux is non-custodial: you configure only an xpub, funds land in wallets only you control, and Coinflux can never move a cent. There’s no honeypot to hack.
You still get the hard engineering — real-time chain watching, an idempotent ledger that makes double-credits mathematically impossible, deterministic EXACT/UNDER/OVER handling, and signed webhooks — just without the custody risk or the percentage cut.
