Cryptocurrency exchange Kraken announced the release of its self-custody cryptocurrency wallet, which can be used by Kraken users and non-users. The wallet will initially support eight blockchains, including Bitcoin, Ethereum, Solana, Optimism, Base, Arbitrum, Polygon, and Dogecoin. The Kraken wallet is open source, and developers can access and contribute to the code. Kraken will also pay developers who discover vulnerabilities through its open source sponsorship program so they can improve the wallet in case of errors. Kraken states that the wallet will collect "the absolute minimum amount of data required as wallet functionality," which aligns with the privacy principles valued by many cryptocurrency users.
