Documented and independently verifiable
Kraken scores 9.2 out of 10 and ranks #1 of 8 in the best crypto exchanges table, strongest on custody & reserves (9.4) and weakest on cost of trading (8.7).
Kraken has run since 2011 without a customer-funds breach, publishes cryptographically verifiable proof of reserves, and holds licences in several serious jurisdictions. Fees sit mid-market and the interface is unglamorous, which is the point.
4 axes, weighted as published in the table’s methodology. Each score below is read from the fact printed under it.
9.4/ 35% of the score
Terms state client assets are segregated and held for the customer; proof of reserves is published as a Merkle tree that a user can check their own balance against, attested by an independent accounting firm. No loss of customer funds on record since launch in 2011.
9.2/ 25% of the score
Holds the Wyoming SPDI bank charter granted in September 2020 — the first issued to a crypto exchange — alongside UK, EU and other national registrations; settled an SEC action over its US staking programme in February 2023 for $30m; no open matter concerning custody of client assets.
8.7/ 20% of the score
Full maker/taker schedule published with volume tiers, plus a separate lower-cost Pro schedule; deposit and withdrawal fees published per rail.
9.1/ 20% of the score
Spot markets across large and mid-cap assets, with derivatives only where locally authorised; direct bank rails in USD, EUR, GBP, CHF, CAD and AUD.
Kraken has been matching orders since 2011, which makes it older than most of the regulation now written around it. In a sector where the median exchange lifespan is measured in bull markets, the plain absence of a customer-funds loss over that span is the most load-bearing fact on its page — not because it guarantees the next fifteen years, but because every rival claim has to be weighed against a shorter record.
The custody arrangement is stated in the terms rather than implied by marketing: client assets are segregated and held for the customer. That sentence is what decides where you stand if the company fails, and it is worth more than any interface.
Kraken publishes reserves as a Merkle tree with a named accounting firm attesting to it, and a customer can verify that their own balance is included in the tree rather than taking a dashboard's word for it. That is the strongest version of this exercise available today, and it still only demonstrates assets. Liabilities — what the exchange owes everyone else — sit outside the proof, which is why we treat a verifiable Merkle tree as necessary rather than sufficient.
Fees sit mid-market: the maker/taker schedule is published in full with volume tiers, and the Pro interface runs a separate, lower schedule. Deposit and withdrawal costs are published per rail, which matters more for most retail users than a basis point on the taker fee. Nothing here is cheap in the way Binance is cheap, and nothing is disguised.
Listing policy is deliberate to the point of slowness. If your reason for holding an exchange account is to be early on newly launched assets, Kraken will disappoint you by design. Derivatives exist only where the local licence allows them, so the product you see depends on the passport you hold.
No exchange is risk-free, but Kraken carries the longest clean record among major venues: no loss of customer funds since it launched in 2011, segregation of client assets written into its terms, and a proof of reserves attested by an independent accounting firm. It also holds a Wyoming SPDI bank charter granted in 2020, which subjects it to supervision most competitors do not face.
Yes, as a Merkle tree with an independent accounting firm attesting to it, and individual customers can verify that their own balance is included. Read it as evidence of assets held, not of solvency — the liability side is not covered by the exercise.
The basic interface is straightforward and the fee schedule is published up front, so there are few surprises. The trade-off is that advanced order types live in a separate Pro interface, and new tokens list late, so anyone chasing recent launches will find the catalogue thinner than at Binance or OKX.
