Landmark $24M Fine: Coinbase's Coding Glitches Undermine Crypto Compliance

Coinbase Admits Coding Errors Led to $24M Ireland Fine Over Transaction Monitoring Breakdown

The Central Bank of Ireland has fined Coinbase Europe Limited €21.46 million ($24.7 million) for a significant anti-money laundering (AML) and counter-terrorist financing (CTF) monitoring failure spanning April 2021 to March 2025, according to a Yahoo report Crypto giant Coinbase fined in Ireland. The regulator cited a breakdown in Coinbase's transaction-monitoring system, which left over 30 million transactions—worth €176 billion—unmonitored for a year, creating compliance gaps as detailed in Coinbase Europe Fined €21M.

Around 31% of Coinbase Europe's total transaction volume during this period escaped scrutiny, with 2,708 suspicious transaction reports later filed, flagging potential links to money laundering, fraud, and child sexual exploitation, the Yahoo article said.

The Central Bank emphasized that Coinbase's failures stemmed from three software errors in its monitoring system, including mishandling special characters in wallet addresses. These flaws went undetected for years, allowing the backlog of unreviewed transactions to accumulate. Coinbase acknowledged the errors were unintentional but admitted the lapses in internal controls and compliance oversight, according to Central Bank fines Coinbase Europe. The firm has since corrected the coding issues, enhanced its monitoring tools, and added stronger oversight to prevent recurrence, as reported in Coinbase Fined €21.5M in Ireland.

The fine marks the first enforcement action against a crypto firm under Ireland's updated AML/CTF procedures, the Yahoo piece notes. Deputy Governor Colm Kincaid highlighted the risks posed by crypto's anonymity and cross-border nature, stating, "Criminals will take any opportunity to evade detection." The initial penalty was reduced by 30%—to €21.5 million from €30.7 million—after Coinbase agreed to a settlement without legal challenge, and the Central Bank's reprimand and financial penalty now await confirmation by Ireland's High Court.

Coinbase's admission of responsibility comes as the company relocates its European operations to Luxembourg by year-end. The move underscores strategic shifts amid regulatory pressures, particularly as the firm seeks to strengthen its compliance infrastructure. In a statement, Coinbase reiterated its commitment to compliance, stating the errors were "corrected" and that the company remains focused on "operating with the highest standards of integrity."

The fine adds to a broader narrative of heightened regulatory scrutiny in the crypto sector. While Coinbase's Q3 2025 earnings showed strong revenue growth and expanded derivatives trading, the Ireland enforcement highlights vulnerabilities in its compliance framework, as noted in Yahoo's ETFs in Spotlight. The incident also aligns with growing concerns from global regulators about crypto's role in illicit finance.

For users, the enforcement does not directly impact trading or asset holdings but raises questions about Coinbase's readiness to meet evolving regulatory expectations. The firm is separately pursuing a U.S. National Trust Charter to expand custody services, a move covered in Coinbase Just Got Fined €21 Million, signaling its intent to bolster legitimacy in a sector still grappling with perceptions of risk.
