Coinbase’s Irish arm has been fined roughly $3.6 million by the Central Bank of Ireland for failing to properly protect customer funds, the regulator’s second enforcement action against the exchange’s European operations in less than a year. The regulator said Thursday it penalized Coinbase Ireland €3,252,618 for breaching safeguarding and outsourcing rules under the country’s Electronic Money Regulations between November 2020 and August 2025.
