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.
