Bitkey is the safe, simple, and secure way to own and manage your bitcoin. It's a mobile app, hardware device, and a set of recovery tools all in one wallet. Bitkey is a 2-of-3 multi-signature wallet which means there are three private keys protecting your bitcoin. You always need two out of three keys to sign a transaction, giving you extra protection. If you hold bitcoin with an exchange, you don't control it. With Bitkey, you hold the private keys and control your money. Recovery Bitkey recovery tools help you recover your bitcoin if you lose your phone, hardware, or both, without needing a seed phrase. Device verification Verification on your Bitkey device provides an additional layer of security for confirming transfers and critical settings. Privacy Keep your balance and transactions private, with protections to ensure that everyone else — from onlookers to our servers — stays in the dark. Inheritance Put an inheritance plan in place for your bitcoin, with a process that’s simple to set up and secure by design.

Proton Wallet is a secure, easy-to-use crypto wallet that gives you sole control of your BTC. We designed Proton Wallet for Bitcoin newcomers, offering an intuitive experience while ensuring only you can access your BTC. Unlike other self-custodial wallets, Proton Wallet offers seamless multi-device support so you can use your wallet from any mobile device or web browser. Similar to how Proton Mail made encrypted email easy-to-use for 100 million users, we hope Proton Wallet can help everyone around the world safely use Bitcoin in a peer-to-peer and self-sovereign way. ** Not your keys, not your coins ** Proton Wallet creates your wallet using a BIP39 standard seed phrase, ensuring seamless recovery and interoperability with other self-custodial wallets, including hardware wallets. This also means you can easily import existing wallets or recover your Proton wallets on other services. Your encryption keys and wallet data are protected with end-to-end encryption, so no one else — not even Proton — can access them. Proton Wallet makes storing and transacting with Bitcoin simple while encrypting all your sensitive data, giving you financial sovereignty and privacy. Proton servers cannot access your BTC and do not even know your historic transactions and balances. ** Freely transact onchain ** The Bitcoin network is the most decentralized, censorship-resistant and secure financial network. Every transaction from Proton Wallet is mined by the Bitcoin network and recorded forever on the Bitcoin blockchain so no one can dispute it. You will pay the current network fee to Bitcoin miners to include your transaction in the blockchain, but no transaction fee is charged by Proton Wallet. Proton Wallet is free for everyone because we believe financial freedom and privacy should be available to all. ** Send Bitcoin via Email ** Bitcoin transactions are permanent and there's no bank you can call if you make a mistake. Copying the wrong 26-character Bitcoin address can be catastrophic. Proton Wallet's unique Bitcoin via Email feature means you only need to verify another Proton Wallet user's email instead, reducing the likelihood of errors. Each BTC address is cryptographically signed with PGP by the recipient's app, ensuring that it belongs to the recipient. ** Keep transactions and balances private ** Due to our incorporation in Switzerland, your data is protected by some of the world's strictest privacy laws. We also minimize data on servers by encrypting all transaction metadata (including amounts, senders, recipients, and notes) on user devices. Each time you receive BTC from someone with Bitcoin via Email, we automatically rotate your BTC addresses, protecting your privacy and making it difficult to connect your transactions on the public blockchain. ** Multiple BTC wallets and accounts ** Proton Wallet makes it easy for you to create multiple wallets, each with its own 12-word seed phrase for recovery. Inside each wallet, you can also create multiple BTC accounts to organize and separate your assets for better privacy. After the default wallet, subsequent wallet creations support an optional passphrase as another layer of protection. Free users can have up to 3 wallets and 3 accounts per wallet. ** Protect your Bitcoin with Proton ** Choose a crypto wallet that's transparent, open source, optimized for Bitcoin, and puts you in control. You can protect your wallet with two-factor authentication and activate Proton Sentinel, our AI-powered advanced account protection system that identifies and blocks malicious logins. Our 24/7 specialist support team is always ready to assist you. Download Proton Wallet now and start protecting your financial freedom.

Verdict

The call

The clearest difference is monetization model: Proton Wallet at free against Bitkey's paid. Bitkey's advantage is update cadence (weekly vs every 3 weeks). On price, rating, review sentiment and ratings volume there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

Proton Wallet holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 138 and 271 respectively. Written reviews complicate that: 71% of Bitkey's written reviews are positive against 65% of Proton Wallet's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Bitkey ships an update weekly, Proton Wallet every 3 weeks. The most recent releases landed on October 25, 2026 and October 30, 2026 respectively.
