Proof of reserves — what exchange attestations mean

Quick answer: Proof of reserves shows a snapshot that customer liabilities may be matched by assets held — at one moment. It is not FSCS protection, not a guarantee against insolvency, and may not cover all liabilities.

After major exchange failures, some platforms publish proof-of-reserves reports. Customers often misunderstand what these prove.

What PoR typically shows

An auditor or firm compares customer token balances to wallets controlled by the exchange at a point in time. Methodology varies.

What PoR does not show

Hidden debts, related-party loans, quality of custody, or future solvency. Celsius and others looked fine until they were not.

Should I trust an exchange because of PoR?+

Treat it as one data point only. FCA registration, your own custody choices, and not over-concentrating funds matter more.
