Kraken launches self-custodial mobile wallet called Kraken Wallet
> The crypto exchange giant Kraken released a self-custodial mobile wallet called Kraken Wallet, and it even published the app's code at launch. Kraken Wallet lets users manage their NFTs, tokens and DeFi positions across Bitcoin, Ethereum, Solana, Optimism, Base, Arbitrum, Polygon and Dogecoin, according to a release from Kraken. Users can also connect to popular decentralized applications and access round-the-clock customer service support. The firm also released Kraken Wallet's code on the developer platform GitHub, stating that third-party review strengthens the wallet's security. The wallet also eschews all but necessary customer data collection in the name of privacy. Kraken holds no sign-in details, email addresses or know-your-customer information, and the firm hides user IP addresses. "Not even internal app performance analytics are collected," the company adds. Kraken notes that Kraken Wallet remains a hot wallet due to Apple iOS CryptoKit not supporting the secp256k1 elliptic curve, which is used to create cryptographic keys and digital signatures on the blockchain networks like Bitcoin. The app must use the internet and use additional software to sign transactions. "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," the firm said. "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." Kraken brought in $49.3 billion in spot market volumes in March, according to The Block's Data Dashboard. The firm also launched an institutional custody platform called Kraken Custody on March 20.
Bitcoin Sign Guy sells the Bitcoin sign for over 16 BTC

> Christian Langalis, colloquially known as the ‘Bitcoin Sign Guy,’ has decided to auction off the piece of paper on which he wrote ‘Buy Bitcoin,’ and held up behind Janet Yellen in 2017 during a House Financial Services Committee. The former Cato Institute intern, who now works on projects on decentralized personal server platform Urbit, stated, “When Bitcoiners ask me about the sign, I tell them, ‘you’d have done the same in my seat.’” According to a Bloomberg article, Langalis turned down a private five-BTC offer in the hopes that the auction would fetch a higher price. His gamble seems to have paid off, with the sale amounting to 16 BTC — over a million dollars at the time of sale and 220% more than the private offer. One bidder appeared to briefly misclick a bid, rocketing the price to 100 BTC before they corrected their bid down to 10 BTC. The anonymous winner of the Bitcoin sign went by the username ‘Squirrekkywrath.’ The note is described as being ‘hastily drawn on a yellow legal pad,’ and ‘one of few widely-recognized physical Bitcoin artifacts, given Bitcoin’s virtual nature’ by the auction house. The auction house requires all individuals placing bids to deposit 1% of their bitcoin bid as collateral. Read more: Don’t download your full node Bitcoin software from Bitcoin.org. Additionally, the sign is characterized as ‘Ink Drawing on Legal Pad’ and the auction winner may select a certificate of authenticity in the form of their choosing, including a paper certificate or a bitcoin ordinal. Langalis earned almost 17 bitcoins from a series of replica editions that he sold in 2019. He says he plans to use the bitcoin earned from the auction to work on current cryptocurrency projects.
