The Kraken Wallet (1>::<307 >::<256 >::<8902>) is a non-custodial app and does not feature a direct cash-out option to your bank account. Since (1>::<307 >::<256 >::<8902>) the Wallet gives you full control of your keys, to convert cryptocurrency to fiat (like USD or EUR), you must first send your crypto from the Wallet to a centralized exchange like the Kraken Exchange. The process requires (1>::<307 >::<256 >::<8902>) you to transfer the assets off-chain to your exchange account’s deposit address, sell the crypto for fiat, and then withdraw the cash. This (1>::<307 >::<256 >::<8902>) is the standard procedure for all self-custody wallets; they are designed for holding and interacting with Web3, not for direct bank transfers.
