Supporting the audit of cryptocurrency

As an important addition to our existing "Halo" suite of auditing tools, PwC can provide assurance services for entities engaging in cryptocurrency transactions. This includes financial audit and control reporting services (using the ISAE and SOC standards) for clients holding crypto assets, such as crypto banks, crypto funds, crypto storage / custody providers and ICOs / STOs.

In an environment where robust controls have been proven effective throughout a business’ cryptocurrency activities, our Halo crypto soluction can:

  1. Provide independent, substantive evidence of the “private key and public address pairing” which is one of the pieces needed to establish ownership of cryptocurrency
  2. Securely interrogate the blockchain to independently and reliably gather corroborating information about blockchain transactions and balances.

The Halo crypto solution currently supports Bitcoin, Bitcoin Cash, Bitcoin Gold, Bitcoin Diamond, LiteCoin, Ethereum, ERC20 - OAX token, and Ripple (XRP), and will soon support Tezos (XTZ) and many more ERC20 tokens.

"With the launch of the control based crypto audit approach and the Halo crypto solution, we are well positioned to increase trust in the nascent crypto and tokenization ecosystem by providing audit and other assurance services to clients holding or transacting in cryptocurrency."
