Centralized Risk vs On-Chain Escrow

Structural differences across custody, privacy, execution latency.

Problem with Centralized Platforms
How HHO.cash Solves It
Mandatory KYC & data retention
Address-only; zero credential surface
Custodial asset exposure & freezes
Funds remain in wallet until atomic execution
Opaque multi-layer fees
Flat 2% seller fee / 0% buyer
Operational delays & withdrawal throttling
Direct on-chain execution & finality
