Frequently Asked Questions
Get clear answers on implementation, security, and support for our specialized tax compliance oracle.
A Real-Time Payment Tax Oracle Network is a specialized blockchain infrastructure layer that automatically calculates, reports, and withholds tax obligations on every transaction as it occurs. You need one to ensure compliance with global tax regulations (like DAC7, FATF Travel Rule, and IRS 6050I), automate reporting, and eliminate manual reconciliation. It's essential for any FinTech, exchange, or DeFi protocol processing payments to avoid significant legal and financial penalties.
