At Kraken, transparency isn’t a slogan – it’s a standard. Our latest Proof of Reserves (PoR), attested as of September 30, 2025, once again verifies that client assets held on our platform are backed 1:1 and beyond. The process covers major cryptoassets, including BTC, ETH, SOL, USDC, USDT, XRP and ADA.
We don’t expect blind trust. We don’t need it. We offer cryptographic evidence.

What our September 2025 report shows
Our PoR captures a complete snapshot of client assets across all services – not just spot balances. It includes margin accounts, futures holdings and staked assets, offering a full-spectrum look at customer exposure as of September 30, 2025:
A quick refresher – what is Proof of Reserves?
Proof of Reserves is a cryptographic process that allows clients to verify — independently and privately — that their assets are included in a third-party accountancy firm’s snapshot of the platform’s liabilities.
We use a Merkle tree to combine individual balances into a single cryptographic hash. Clients receive a personalized Merkle proof, which they can use to confirm inclusion without revealing personal details. The independent accountancy firm then confirms that Kraken’s onchain holdings exceed total client balances — effectively verifying full reserves without assumptions.
Why Kraken’s PoR goes further
While more exchanges are now offering “PoRs” in some form, not all of them offer the same level of rigor or transparency. Here’s what sets ours apart:
1. We account for liabilities, not just assets
Some platforms show what they hold — but skip what they owe. We include total client liabilities in every PoR. Anything less isn’t a full proof of reserves.
2. User-level verification
Every client can verify their own inclusion using our open-source Merkle verification tool. This isn’t just about trust – it’s about verification.
3. A decade of consistency
We first pioneered PoR in 2014 — and we haven’t stopped. Kraken conducts PoR regularly and methodically, not just during news cycles.
PoR is vital. It’s not about promises. It’s about proof – visible, cryptographic, third-party-verified proof. Kraken’s process is built to withstand scrutiny and empower users with information.
What’s next – expanding scope
We’re committed to publishing PoRs quarterly, alongside our financial disclosures, to ensure users have a regular window into platform solvency. We’re also actively working to expand the coverage of our PoRs to include more supported assets, giving a broader view of the reserves across our ecosystem.
Since the beginning, Kraken has stood for accountability, independence and crypto-first values. We believe transparency should be an industry norm, not an afterthought. That’s why we’ll keep raising the bar.
