[Kraken's Krak Launches Cashback Debit Card, Payroll Deposit, and High-Yield Vaults] According to The Block, Kraken announced that its Krak app has launched a Mastercard debit card in the UK and EU, supporting real-time multi-asset payments with 1% cashback. Additionally, it introduced 'Vaults,' a high-yield feature integrated with DeFi protocols, targeting annualized returns exceeding 10%. The app also supports direct payroll deposits via IBAN, aiming to position Krak as a multi-asset 'primary account' alternative to traditional bank accounts.
