The well-known cryptocurrency exchange Kraken introduced Kraken Wallet, a self-custodial mobile wallet, and even made the app’s code public when it first launched.
As per a Kraken announcement, users can manage their NFTs, tokens, and DeFi holdings across several cryptocurrencies such as Dogecoin, Ethereum, Solana, Optimism, Base, Arbitrum, and Polygon. Users can also obtain 24/7 customer service support and connect to well-known decentralized applications.
The company further stated that third-party evaluation enhances the wallet’s security by posting the code for Kraken Wallet on the development platform GitHub.
For the sake of privacy, the wallet also rejects the acquisition of any but essential customer data. Email addresses, sign-in credentials, and know-your-customer data are not stored by Kraken, and user IP addresses are concealed by the company. The company further states that not even internal app performance analytics are gathered.
According to Kraken, the reason why Kraken Wallet is still in demand is because Apple iOS CryptoKit does not support the secp256k1 elliptic curve, which is necessary for generating digital signatures and cryptographic keys on blockchain networks such as Bitcoin. The app has to be connected to the internet and utilize extra software to sign transactions.
The company said, “This means that the private keys must be exposed — at least during signing — within the memory of the sandboxed app environment. This leaves them more exposed to potential threats than a wallet which uses a secure element to sign transactions.”
Further, the firm added, “Despite the inability to perform the signing on the secure elements directly, which would offer increased protection, we have committed to providing an open-source mobile crypto wallet that prioritizes security, transparency and user control.”
