Wallet Ownership Proof

Self-hosted wallets (also referred to as unhosted wallets) fall under the scope of the FATF’s Travel Rule. When a transaction occurs between a VASP and a self-hosted wallet, the wallet’s ownership is to be proved*.

VASPs can safeguard against sending funds to wallets their user does not control by requesting a proof of private key ownership.

Wallet ownership can be proved in various ways, namely via: 

• Address Ownership Proof Protocol (AOPP) 

• A Satoshi Test 

• Manual Signing, or  

• By Visual Proof (or Screenshot).

Wallet Ownership Proof is also known as Private Key Control Procedure (PKCP).
