What Does “Proof of Reserves” Mean and Why Does it Matter?

• Proof of reserves is intended to demonstrate that a crypto trading platform holds assets that correspond to customer balances at a specific point in time.
• Proof of reserves is not an internal accounting metric, meaning it does not show the company’s debts and liabilities.
• Crypto assets are not covered by deposit insurance, and CIPF coverage does not apply to crypto assets.

Key takeaways: Proof of reserves provides transparency in custody and backing.It can provide additional information about custody practices when evaluating different platforms, but it has limits and should be viewed alongside other factors like regulation, security controls, and withdrawal practices.
 

When people say “proof of reserves,” they usually mean one of two related things:

• Proof of assets: confirmation a platform controls certain on-chain wallets and holds specific amounts of crypto.
• Proof of customer balances: a way of showing total customer balances (liabilities to customers) are included in the calculation, often using a privacy-preserving method.

The objective is to confirm customer balances are backed by real assets the trading platform (or custody provider) rightfully holds and that are readily available.
 

Most proof of reserves approaches include a few basic steps:

• A snapshot is taken of all customer balances at a point in time.
• Those balances are combined in a way that lets users verify inclusion without exposing everyone’s information.
• The platform provides evidence of the on-chain addresses or custody wallets that hold the reserves.
• Registered platforms such as Ndax are required to provide regular reporting to regulators that includes information about client asset custody and controls.

Not by default. Proof of reserves is a transparency signal, but it does not indicate business liabilities. What this means is proof of reserves is a reassuring data point, but not a guarantee. Proof of reserves is not a replacement for security controls.

Canadian regulators have cautioned that crypto assets are high-risk, and Canadians who choose to trade crypto generally look for regulator-aligned services with clear disclosures and security practices. Crypto assets are not covered by the Canadian Investor Protection Fund (CIPF) or deposit insurance. Ndax operates within Canadian regulatory requirements.

Ndax relies on ongoing regulatory reporting and independent audits. Regulated reporting and audits provide a more complete view of client asset backing and segregation than a public proof of reserves dashboard. Independent auditors review Ndax’s internal controls, governance, and accounting practices as part of its regulatory and financial reporting processes.

Common things to check include how frequently the reports are updated, whether reserves can be confirmed on-chain or described through a custody model, whether it covers all major assets, and whether anything is excluded.

One potential concern is when a crypto platform claims it is “fully backed” without providing supporting evidence, methodology, or dates. Another red flag is an incomplete proof of reserves report that only shows some assets with no explanation.

The absence of proof of reserves is not by default a concern. Other credible transparency signals, like custody disclosures or third-party audits, can replace proof of reserves. The practical point is that users should understand how their assets are custodied and what controls are in place.

What is proof of reserves?
Proof of reserves is a method used by many platforms to confirm it holds enough crypto to match customer balances at a point in time.

Why does proof of reserves matter?
It matters because proof of reserves can increase transparency and confirm customer assets are backed and readily available.

Does proof of reserves prove solvency?
No. Proof of reserves typically don’t include business liabilities and debts. However, regulated crypto trading platforms like Ndax disclose its balance sheet and liabilities in its audited reports.

How often should proof of reserves be updated?
The best frequency depends on the platform’s model and what information the report includes. By default, more frequent updates are generally more useful to users and the community.

Can users verify their own balance in proof of reserves?
On some platforms, this is possible. Users can confirm their balance was included without revealing private information.
