KYA (Know Your Address)

KYA, or Know Your Address, is the practice of assessing the risk profile of a specific blockchain address itself — its history, labels, and behavior — independent of who legally owns it. It is address-centric screening, distinct from customer-centric KYC.

What it means

The distinction matters because a single legal customer can control many addresses, and a single address's risk profile is knowable directly from public blockchain data even before any identity is attached to it. KYA lets a business evaluate a deposit or counterparty address on its own merits — its past transactions, its label history, its exposure to known risk — regardless of whose name is on the account.

KYA is the analytical foundation that FreezeRadar-style wallet scanning is built on: every finding in a scan is, at its core, a statement about what a specific address's on-chain history shows, assembled from label data, sanctions lists, and pattern detection applied to that address and its transaction graph.

Real-world example

Before accepting a large deposit, a treasury team might run a KYA check on the sending address itself — checking its blacklist status, sanctions exposure, and counterparty history — as a standalone assessment separate from any identity verification already done on the counterparty as a customer.

In FreezeRadar

A FreezeRadar wallet scan is fundamentally a KYA assessment — every finding is derived from the address's own on-chain history, not from any claimed identity behind it.
