  In this paper we focus on one part of the trust infrastructures needed for
the future virtual assets industry, namely the attestation infrastructure
related to key management in private wallet systems. Our focus is on regulated
private wallets utilizing trusted hardware, and the capability of the wallet to
yield attestation evidence suitable to address requirements in several
use-cases, such as asset insurance and regulatory compliance. We argue that
attestation services will be needed as a core part of the key management
lifecycle for private wallets in true decentralized systems.
