Kraken
Exchange and institutional venue

Long-running exchange with retail, pro trading, staking, OTC, institutional, and everyday-money services. Kraken Card connects eligible UK, EEA, and US customers to cash and crypto balances through jurisdiction-specific Kraken entities and issuers: Monavate issues the UK and EEA Mastercard programs, while the current US program is a Visa. Crypto is converted to fiat at purchase and a variable spread can apply, so zero card transaction fees do not mean zero conversion cost.
