Overview
Kraken is one of the oldest US-based exchanges, respected for security, reliability and transparency (regular proof-of-reserves). Kraken Pro offers competitive maker/taker fees, while the instant-buy flow is pricier. It supports 230+ assets across 190+ countries and requires KYC. It is a frequent choice for users who value a long, breach-free operating history.
Availability
Kraken is available in: United States, EU, UK, 190+ countries. Always confirm availability for your country on the official site, as regional support changes. Availability, regulation and tax treatment vary by country. Check your local laws before trading, and confirm current details on the official site. Regional note — India: Indian residents face 30% tax on crypto gains and 1% TDS on transactions above ₹50,000 per the Finance Act 2022.
Fees deep-dive
Kraken runs two distinct pricing tracks. The "Instant Buy" flow aimed at beginners charges a spread plus a fee that commonly lands well above 1% all-in depending on payment method — broadly comparable to Coinbase's simple flow and well above Binance's flat spot rate. Kraken Pro (free to use — just a different interface on the same account) uses a maker/taker schedule starting at 0.25% maker / 0.40% taker at the lowest 30-day volume tier and stepping down with volume, reaching 0.00% maker / 0.10% taker at the highest published tiers — competitive with, and in the maker case cheaper than, Binance's base rate. Stablecoin and some promotional pairs carry reduced fees. Withdrawal fees are set per asset and network on Kraken's published fee schedule and move with on-chain conditions; USD withdrawals via bank wire carry a flat fee, while ACH, where available, is typically free. Deposits are generally free for crypto and bank transfer, with card/instant funding carrying its own processing cost. Compared with Binance, Kraken Pro's top-tier maker fee is actually lower, though Binance's flat, no-tier-climbing 0.10% is simpler for a mid-size trader to reach; compared with Coinbase, Kraken Pro undercuts Coinbase Advanced Trade at most volume tiers, while both share the pattern that their simple/default flow is the expensive one — a trap for inattentive users on either platform.
Security architecture
Kraken has never disclosed a confirmed exchange-level custody breach in its operating history dating to 2011, a track record it markets directly and which independent reviewers generally corroborate. It was the first major exchange to publish a cryptographic proof-of-reserves audit and continues to publish these quarterly; the audits are conducted by The Network Firm, an independent CPA firm, using a Merkle-tree structure that lets individual users verify their own balance is included in the total without exposing other customers' account data, alongside disclosure of both assets and client liabilities to demonstrate solvency rather than just asset existence. Kraken states client crypto assets are held primarily in offline, geographically distributed cold storage, with a limited hot-wallet balance maintained for withdrawal liquidity. 2FA options include authenticator-app TOTP and hardware security keys (YubiKey/FIDO U2F), and Kraken supports a Global Settings Lock feature that time-locks changes to withdrawal addresses and security settings to blunt account-takeover attacks. This is consistent with FlixoCrypt's existing research showing no material custody breach on record for Kraken, making it one of the stronger security track records among the exchanges reviewed here.
KYC & verification
Kraken requires tiered identity verification before withdrawals or full trading access. The entry "Starter" tier requires only an email and basic details and allows limited deposits with no withdrawals; "Intermediate" verification requires full legal name, address, date of birth and a government-issued ID, typically approved within minutes to a few hours, and unlocks fiat withdrawals and higher limits. A "Pro" tier, required for the highest limits, adds proof-of-address and, for larger accounts, a short questionnaire on source of funds, and can take one to several business days depending on volume. Document requirements — accepted ID types, proof-of-address formats — vary by the user's country, since Kraken's onboarding adapts to local regulatory requirements rather than using one fixed global checklist.
Mobile app
Kraken's main app rates around 4.5 out of 5 on Google Play, and the separate Kraken Pro app rates slightly higher at roughly 4.6; FlixoCrypt could not independently confirm precise current iOS App Store figures at time of writing. Kraken splits its mobile experience into two apps — a simple buy/sell app aimed at beginners and a Kraken Pro app exposing the full order book, charting and Pro fee schedule — mirroring the platform's two-tier fee structure and letting each audience use an interface sized to their needs rather than forcing a beginner into a dense trading terminal. Biometric login and standard account-security controls are available on both apps. User feedback commonly praises reliability and the depth of the Pro app's charting/order tools, while some reviews note the two-app split itself as mildly confusing for new users unsure which one to download.
Customer support
Kraken offers 24/7 support via live chat and an in-app voice-call option that connects users directly to a support agent, alongside a large self-service Support Center. Kraken states it aims to resolve issues typically within 24 hours, and third-party reports on social-media escalations have cited response times in the roughly one-to-four-hour range depending on volume, though these figures fluctuate with market conditions and aren't independently guaranteed. There is no general inbound public phone number for cold-calling support — the voice option is initiated from within the app or website. Kraken's support is generally regarded as a relative strength versus offshore-leaning rivals, consistent with its reliable, security-first positioning.
Pros
- Strong security and reliability reputation
- Competitive Pro fees
