Cygnus Pay was created by Mr Hat, the founder of Cygnus Coin. While building the Cygnus ecosystem, Mr Hat saw firsthand how difficult it was for normal merchants and everyday internet users to start accepting crypto payments.
Existing payment gateways were expensive, overly complex, and made the process even harder instead of easier. The tools that were supposed to help were actually creating more barriers.
With the support and encouragement of early supporters in the Cygnus Community, Mr Hat designed and coded the entire platform from the ground up — building the payment infrastructure that the crypto space actually needed.
The name Cygnus comes from the constellation — one of the most prominent in the northern sky. Just as the Swan has guided navigators for millennia, Cygnus Pay aims to guide the world into a future where crypto payments are the default.
Zero platform fees on payment links. Merchants keep 100%.
Create a link in 30 seconds. No coding, no contracts.
All chains, all tokens, one dashboard.
