In the wake of major crypto exchange collapses in 2022—such as Celsius, Voyager, and FTX—investor trust in centralized platforms has taken a significant hit. In response, many exchanges have stepped up efforts to demonstrate transparency, with one of the most effective methods being the publication of Proof of Reserves (PoR) reports. These audits aim to reassure users that their deposited assets are fully backed and not being misused.
While the concept sounds promising, not all PoR reports are created equal. There is currently no universal standard for how these proofs should be conducted, leading to wide variations in credibility and depth. For an exchange to earn a spot on this list, it must meet three critical criteria:
- Independent third-party verification
- Unannounced or real-time blockchain snapshots
- Full accounting of liabilities
When all three conditions are met, the report moves beyond simple reserve verification and becomes closer to a true Proof of Solvency, as it accounts for both assets and obligations. This distinction is crucial—transparency should go beyond just showing holdings.
Exchanges like Binance and BitMEX have released reserve reports, but since they rely on self-audits without independent oversight, they do not meet our threshold for inclusion. The following platforms, however, stand out for their rigorous and transparent practices.
Kraken: Leading the Transparency Charge
Kraken consistently ranks at the top for transparency—and for good reason. Long before Proof of Reserves became a hot topic in the crypto world, Kraken was already publishing comprehensive asset audits. The exchange partners with Armanino LLP, a respected accounting firm, to conduct surprise audits at random intervals. These audits are not only independent but also include a full assessment of user liabilities, making them one of the few genuine solvency checks in the industry.

What sets Kraken apart isn’t just compliance—it’s innovation. In 2021, Kraken became one of the first major exchanges to integrate the Lightning Network, enabling faster and cheaper Bitcoin transactions. This forward-thinking approach extends to its overall security model, regulatory compliance, and user protection policies.
Kraken’s commitment to transparency doesn’t stop at audits. The exchange regularly publishes detailed reports on its financial health, custody practices, and operational resilience. For users concerned about where their funds are stored and how they’re protected, Kraken offers one of the most comprehensive windows into exchange operations available today.
Uphold: Real-Time Transparency and Full Asset Breakdown
Uphold takes transparency to another level with its real-time public dashboard, which displays up-to-the-minute data on asset reserves, user obligations, and transaction activity. Unlike most platforms that publish periodic snapshots, Uphold allows anyone to view current holdings across all supported assets—including both digital currencies and fiat.
This live visibility is a game-changer. Users can see exactly how much of each asset Uphold holds in reserve and compare it against total customer balances. More importantly, Uphold doesn’t just audit its top five holdings—it provides a full breakdown for every single asset on its platform. This level of granularity is rare and significantly enhances trust.
The exchange’s Proof of Reserves reports are independently verified and include liability calculations, ensuring a complete picture of solvency. Uphold’s model reflects a shift toward continuous transparency rather than one-off audits, aligning more closely with the real-time nature of blockchain technology itself.

Frequently Asked Questions
Q: What is Proof of Reserves?
A: Proof of Reserves is a cryptographic audit that verifies an exchange holds enough assets to cover user deposits. It typically involves publishing wallet addresses and blockchain snapshots to prove ownership of funds.
Q: Why is third-party verification important?
A: Independent audits reduce the risk of manipulation or falsified reports. When a reputable accounting firm validates the data, users can have greater confidence in the results.
Q: Does Proof of Reserves guarantee my funds are safe?
A: While PoR is a strong indicator of financial health, it doesn’t eliminate all risks. It should be one factor among others—such as regulatory compliance, security measures, and insurance policies—when choosing an exchange.
Bitstamp: Longstanding Commitment to Audits and Compliance
Bitstamp has been publishing audited Proof of Reserves reports since 2016, making it one of the earliest adopters in the industry. What makes Bitstamp’s approach particularly credible is its partnership with Ernst & Young (EY), one of the "Big Four" accounting firms. These annual audits include both asset verification and liability assessments, meeting our standard for true solvency reporting.
Beyond audits, Bitstamp emphasizes regulatory compliance across its global operations. The company reports that approximately 30% of its workforce is dedicated to compliance, risk management, legal affairs, security, and internal auditing. This heavy investment in governance underscores its commitment to operating as a trustworthy financial institution.
Bitstamp serves markets in Europe, the U.S., and beyond, adhering to strict AML and KYC regulations. Its long track record—combined with consistent third-party audits—makes it a reliable choice for users prioritizing security and regulatory adherence.
Why These Criteria Matter
Transparency in crypto isn’t just about publishing numbers—it’s about publishing meaningful numbers. A reserve report that lacks independent verification or ignores liabilities can be misleading. For example:
- An exchange might show it holds 100,000 BTC in cold storage—but if it owes users 120,000 BTC, it’s insolvent despite appearing well-reserved.
- Self-issued reports can be manipulated through techniques like “hot potato” transfers, where assets are briefly moved between affiliated wallets during a scheduled audit.
That’s why unannounced audits and real-time data are essential. They prevent gaming the system and ensure accuracy.
Final Thoughts: Choosing a Trustworthy Exchange
As the crypto industry matures, users must demand more than promises—they need proof. The exchanges listed here—Kraken, Uphold, and Bitstamp—are setting benchmarks for transparency by combining independent audits, real-time data, and full liability disclosures.
When evaluating any platform, ask:
- Is the audit conducted by a recognized third party?
- Are liabilities included?
- Is the snapshot random or real-time?
These questions help separate genuine accountability from marketing optics.
Frequently Asked Questions (Continued)
Q: Can Proof of Reserves be faked?
A: Yes—if proper safeguards aren’t in place. Without unannounced snapshots or third-party verification, exchanges could temporarily borrow funds to pass an audit. This is known as "proof of nothing."
Q: How often should Proof of Reserves be updated?
A: Monthly updates are ideal for static reports. However, platforms like Uphold that offer live dashboards provide even greater transparency.
Q: Are decentralized exchanges (DEXs) more transparent than centralized ones?
A: In many ways, yes. DEXs operate on public blockchains where all transactions are visible by default. However, CeXs can achieve high transparency through regular audits and open reporting.
