How to Audit Cryptocurrency: A Guide to Popular Audit Tools

Table of Contents

More businesses use cryptocurrency every day. This makes learning how to audit cryptocurrency very important. When big crypto exchanges failed, it showed why this matters. Companies need to prove they really own the crypto they say they have.

For crypto accounting firms and businesses with lots of digital assets, crypto audits aren’t  just nice to have. It’s needed for following regulations around the world, keeping trust, and building a great business.

This guide looks at the best ways to audit  cryptocurrency. We’ll review the top crypto accounting software options. We’ll also look at advanced methods like Merkle Tree Proof of Reserves. This will help accounting pros and businesses understand crypto auditing tools and build good checking practices.

Understanding Crypto Auditing Basics

Crypto auditing is different from traditional auditing. Traditional money sits in bank, brokerage, or other traditional custodial accounts. Crypto lives on blockchain networks.

This means you need special tools and methods. You have to prove three things: you own the crypto, you have all of it, and you know what it’s worth. The auditing process must address several key challenges: proving wallet ownership through cryptographic signatures, reconciling on-chain and off-chain data, managing multi-blockchain complexity, and ensuring comprehensive transaction tracking across decentralized finance (DeFi) protocols.​ Each type requires specialized tools and expertise to execute effectively.​

Modern cryptocurrency auditing has evolved beyond simple balance verification to encompass real-time monitoring, automated reconciliation, and advanced cryptographic proof methods. The integration of blockchain analytics, proof of reserves mechanisms, and enterprise-grade accounting software has transformed how organizations approach digital asset verification and reporting.

Top 5 Crypto Auditing Software Tools

1. Bitwave – Enterprise Digital Asset Platform

Strengths: Bitwave is top crypto accounting software for big companies. It works with over 50 different blockchains. The software connects to popular accounting systems like QuickBooks and NetSuite. It can match your crypto records automatically. This saves time and reduces mistakes.

The software has powerful rules that can sort thousands of transactions instantly. It can calculate fair value prices with one click. Bitwave has SOC 1 and SOC 2 Type 2 certifications meeting high security standards.

Weaknesses: It is primarily developed as a crypto subledger tool and not purpose built for auditing.

2. Lukka – High-Level Data Management

Strengths: Lukka provides high-quality solutions with coverage of 100+ blockchains and automatic matching systems. The platform has complete pricing data covering 10,000+ trading pairs and 27 exchanges. It has over 90 billion trading records for accurate fair market value calculations.

Lukka’s system maps digital asset symbols to official identifiers. This eliminates mix-ups across exchanges. The system creates 50+ pre-made reports made for institutional digital asset management.

Weaknesses: The platform’s complexity and high pricing may be too much for smaller companies. This might limit use for highly regulated financial institutions. The system needs custom implementation and  technical knowledge for best use.

3. Cryptio – Digital Asset Accounting Platform

Strengths: Cryptio specializes in accounting compliance for institutional investors. It offers deep integration with existing financial systems. The platform provides complete transaction matching and data quality checking across blockchain, exchange, and custodial data.

Cryptio supports both US GAAP and IFRS compliance with audit-ready reporting abilities. The solution focuses on transparency in financial records for institutional clients.

Weaknesses: Initial setup and ongoing care require specialized accounting and technical knowledge. This could create barriers for smaller teams. Full PCAOB audit compliance is supported but not independently certified. This could affect suitability for US public company audits. DeFi and staking matching depth is moderate compared to specialized DeFi solutions. Like Bitwave, Cryptio is a crypto subledger and not purpose built for auditors.

4. Allium – Real-Time Blockchain Data Platform 

Strengths: Allium stands out for its real-time data abilities and focus on data quality. It supports over 60 major blockchains and organizes transactions in a double-entry book format, making net flow and balance calculations easier. Its platform features unified schemas, automated data verification, and self-healing, which reduces data errors and boosts trust. Allium covers a wide range of use cases, including institutional DeFi, NFT marketplaces, stablecoins, and in-depth wallet analytics. Notable clients like Visa and Grayscale rely on Allium for accurate, up-to-date blockchain data. Security is robust, with SOC I Type 1 and SOC II Type 1 & 2 certifications.

Weaknesses: The platform is advanced and best suited for analysts or organizations with technical backgrounds. It does not have an application user interface so some coding knowledge is required. Smaller teams or those with basic needs may find the learning curve steep. Pricing and feature sets are tailored for enterprise-grade use, which could be limiting for small businesses or teams seeking simpler tools.

5. SonarX – Institutional Blockchain Data Infrastructure

Strengths: SonarX is built for institutions needing scalable, trustworthy blockchain data infrastructure. It indexes over 100 blockchains, offering full historical and real-time access for compliance, audit, and reporting purposes. The platform is designed for hyper-scale performance, powering mission-critical workflows for banks, custodians, tax and audit software, and regulatory bodies. SonarX’s system meets strict data quality standards, supports SOC 2 and GDPR compliance, and is capable of handling complex, multi-chain environments typical for financial institutions.

Weaknesses: SonarX’s enterprise focus and infrastructure scale may be unnecessary for smaller organizations or those new to digital asset accounting. The solution is best-suited for financial institutions and large enterprises with the technical capacity to integrate and maintain institutional blockchain data pipelines. Like Alliu, it does not have an application user interface so some coding knowledge is required.
