The European Union’s Cyber Resilience Act took effect on Friday, Sept. 11, 2026, and with it comes a legal obligation that will reshape how crypto wallet manufacturers handle security failures: report actively exploited vulnerabilities within 24 hours or face fines running into the tens of millions of euros. The rule applies to hardware and software wallet providers including Trezor, Ledger, BitBox and Zilliqa, and it arrives at a moment when the wallet industry has already been tested by a string of breaches and phishing campaigns.
A compliance clock with real teeth
The Cyber Resilience Act is not a vague statement of principle. It sets out a strict sequence of deadlines that manufacturers of any “product with digital elements” sold in the EU must now follow once a vulnerability is being actively exploited. An early warning is due within 24 hours of a company becoming aware of the issue. A fuller notification must follow within 72 hours. Once corrective measures are available, a final report is required within 14 days, and for the most severe incidents, companies have up to one month to deliver that final report.
Failure to comply is expensive. Under Articles 13 and 14 of the regulation, companies that fall short face fines of up to €15 million ($17.3 million) or 2.5% of their worldwide annual turnover, whichever figure is higher. A separate penalty of up to €5 million applies if a company submits information that is incorrect, incomplete or misleading. Because the law covers any digital product sold into the EU market, it applies well beyond crypto, but its impact on wallet makers is immediate and specific, given how central these devices and apps are to safeguarding private keys and user funds.
Why regulators moved now
The timing is not incidental. The wallet industry has spent recent months absorbing a series of security incidents that exposed how fragile the supply chain around crypto custody can be. Trezor disclosed that a data breach at its shipping partner ShipMonk, revealed Sept. 4, ultimately affected an additional 67,000 US customers, a sharp revision upward from an initial estimate of just 14,000 victims. Separately, phishing campaigns targeted both Trezor and BitBox customers through compromised third-party email services, exploiting trust in routine account communications. In June, Zilliqa disclosed a vulnerability in a Ledger app that could have exposed private keys through onchain data, a reminder that risk in this industry does not stop at the hardware itself but extends into the software and services built around it.
These incidents echo a broader pattern of weaknesses across the industry’s edges. Security researchers have previously flagged dozens of iOS crypto wallet apps found vulnerable to key theft flaws, while custodial platforms have faced their own exposure problems, including a case where Revolut leaked customer Bitcoin data to a fake government agency. Separate reporting detailed how a similar incident showed fake regulator emails managed to defeat identity verification checks. Taken together, these episodes illustrate a common thread: attackers are increasingly targeting the people and processes surrounding wallets and exchanges, not just the cryptography itself.
What the new rule changes in practice
For crypto users, the Cyber Resilience Act does not eliminate risk, but it does formalize expectations that previously depended on each company’s own goodwill and public relations judgment. Wallet manufacturers can no longer decide, on their own timeline, when and how to disclose an actively exploited flaw affecting EU customers. The law converts what used to be a reputational calculation into a legal deadline backed by financial penalties.
This matters because the consequences of delayed disclosure in this industry are not abstract. Wallets hold the private keys that control access to crypto assets, and a vulnerability left unreported even briefly can leave a wide window for attackers. The law’s tiered structure, an early warning within 24 hours, a fuller report within 72 hours, and detailed follow-up reporting once fixes exist, is designed to compress that window while still giving companies room to investigate before making sweeping public statements.
The rule also applies uniformly regardless of company size or reputation, which puts smaller wallet makers under the same compliance pressure as established players. That could raise operating costs for the industry as a whole, particularly for firms without dedicated security and legal teams already built to handle rapid incident response.
What to watch next
- Whether any wallet manufacturer faces enforcement action or fines under the new deadlines in the coming months, which would set a practical benchmark for how strictly the rule is applied.
- How companies structure public vulnerability disclosures going forward, given the risk of separate €5 million penalties for incomplete or misleading reports.
- Whether the broader pattern of supply-chain and phishing incidents, including cases affecting liquidity providers hit by exploits elsewhere in crypto infrastructure, prompts additional EU scrutiny of third-party vendors used by wallet makers.
- Whether other jurisdictions outside the EU move toward similar mandatory reporting timelines for crypto hardware and software providers.
