Melusina

Melusina — the open-source infrastructure layer that powers paype.cc. Built for compliant, multi-party financial services at scale.

What Melusina provides

• Multi-party custody — funds require cryptographic approval from multiple parties before moving, preventing unilateral access
• Cryptographic signing — every action on the platform is signed with the user’s private key, creating a tamper-evident audit trail
• Compliance automation — KYC/KYB orchestration, AML screening, OFAC monitoring, and SAR generation are built into the platform layer
• Payment rail integration — SWIFT, SEPA, card networks, and blockchain bridges, abstracted behind a unified API

Why open source

Open source means the infrastructure powering your money can be audited by anyone. There are no black boxes in Melusina’s custody or signing logic. Security researchers, regulators, and enterprise customers can verify how the system works rather than relying on assurances.

For paype users

You interact with Melusina every time you confirm a transaction, read your audit trail, or receive funds. It’s the foundation — paype.cc is the product layer on top.
