What is Fluxis?
Fluxis is an API-first platform that provides a standardized way of sharing payment instructions between parties. Built as a B2B solution, Fluxis is designed to simplify integrations between partners and service providers through the implementation of the NASPIP protocol, developed by our team.
Think of NASPIP as the "common language" for payments: a shared standard that makes communication seamless across different systems. By integrating Fluxis once, your business gains the ability to connect with any future partner or provider that also adopts the protocol—no need for multiple custom integrations.
In short, Fluxis enables:
- 🔐 Verifiable Payment Requests: Every payment instruction is signed by Fluxis, so payers can confirm its authenticity before sending funds, reducing errors and preventing fraud
- 🌐 Multi-asset, Multi-network Support: Merchants can offer multiple payment options in a single request, and payers choose the network or asset that best fits their needs
- 📱 Static Payment Links & QR Codes: Easy-to-use static codes that generate preloaded payment requests, perfect for small businesses and recurring use cases
- 🚀 Upcoming Internal Network (coming soon): An off-chain layer for real-time payments, where Fluxis can process and settle transactions on behalf of payers, reducing costs and latency
- 📈 Expanding Settlement Options: Production settlement monitoring currently covers Polygon, Base, Avalanche, and Arbitrum; the UAI catalog includes USDC, USDT, USDC.e, and more across Ethereum, Arbitrum, Optimism, BSC, Solana, Tron, and others—with broader network rollout on the roadmap
