How to Audit Crypto: A Guide for Modern Auditors

Table of Contents

Crypto auditing is getting more important every day. More companies now hold digital assets on their books. But learning how to audit cryptocurrency is still new to many auditors. This guide breaks down the basics in simple terms.

What Makes Crypto Different from Regular Assets?

Digital assets are not like cash or stocks. They live on something called a blockchain. Think of it as a digital ledger that everyone can see but no one can change.

Here’s what makes crypto unique:

  • No central bank controls it
  • Transactions happen 24/7
  • Records are permanent
  • Ownership depends on digital keys

These differences create new risks. Auditors need to learn new ways to check these assets.

The Biggest Crypto Audit Risks

Can You Prove the Company Owns It?

Auditing crypto ownership is tricky. With regular assets, you can hold a stock certificate. With crypto, ownership comes from having the right digital key.

Auditors must check:

  • Does the company control the private keys?
  • Are assets stored safely?
  • Who has access to the wallets?
  • Are customer assets separate from company assets?

Getting the Right Value

Crypto prices change fast. Bitcoin can swing 10% in a day. This makes valuation hard.

Key steps include:

  • Pick reliable price sources
  • Check prices at the right date and time
  • Test for permanent losses in value
  • Understand 24/7 trading impacts

Making Sure Nothing is Missing

Companies might have crypto in many places. Some on exchanges. Some in cold storage. Some in lending programs.

Auditors need to:

  • Find all company wallets
  • Check all transactions
  • Look for hidden related party deals
  • Make sure records are complete

Step-by-Step Crypto Audit Process

Step 1: Understand the Business

Before you start, learn how the company uses crypto:

  • Do they mine it?
  • Do they trade it?
  • Do they hold it long-term?
  • Do they offer custody services?

Each use case has different risks.

Step 2: Check Ownership

This is the hardest part of learning how to audit cryptocurrency:

For Company-Held Assets:

  • Get a list of all wallet addresses
  • Use blockchain tools to check balances
  • Test cryptographic signatures
  • Verify the company controls the keys

For Custodial Assets:

  • Get confirmations from custodians
  • Review custody agreements
  • Check insurance coverage
  • Test segregation controls

Step 3: Test Values

Crypto valuation needs special care:

  • Use multiple price sources
  • Check cut-off procedures
  • Test impairment calculations
  • Review fair value methods

Step 4: Check Internal Controls

Good controls prevent losses:

  • Who can access private keys?
  • How are transactions approved?
  • Are duties properly separated?
  • How are assets monitored?

Common Audit Tools and Tech

The right tools are crucial when learning how to audit crypto effectively. Manual processes don’t work well with blockchain data.

Modern audit tools can:

  • Pull data directly from blockchains
  • Verify wallet ownership automatically
  • Track transactions across networks
  • Generate audit reports quickly

The best tools save huge amounts of time. Some auditors report cutting engagement time by over 90%.
