Paykassa

Crypto aggregator since 2017 with email-only onboarding and a mass-payout API.

Paykassa is a cryptocurrency payment aggregator operating since 2017 that lets websites accept 16 cryptocurrencies via API or a hosted payment form, and send bulk payouts. Merchant onboarding requires only an email address with no KYC verification, which positions it for high-risk online businesses; the site openly advertises integrations with CMS, exchanger and HYIP platforms. Incoming payments are free while withdrawals cost 4% plus the network fee, with negotiated rates for larger merchants — the fee was about 1% at launch and was later raised. The service claims roughly 66,000 users, 30,000 connected merchants and 39M+ processed operations. The operating legal entity is not disclosed in its public documents; its Trustpilot profile shows a shared Wyoming registered-agent address and a 4.0/5 score from 71 reviews.

For SMM businesses: A long-time default in the SMM panel ecosystem: instant email-only onboarding without KYC, tolerance for high-risk verticals, plug-in modules in common panel scripts and a mass-payout API. Trade-offs: the 4% payout commission is heavy for thin-margin panels, and the anonymous operating entity means no legal recourse.
