## Overview

Fluidkey wraps stealth addresses in a payments product polished enough that people actually use it, across seven EVM chains, with real traction for receiving funds privately. Every incoming payment lands on a freshly generated address with its own smart account, derived automatically from the user's viewing and spending keys, so a shared payment link never becomes a public ledger of everything it has ever received, and the user still sees one unified balance. What it delivers is unlinkability: amounts and activity stay readable on chain, which is a different and far lighter guarantee than encrypting them.
