Hardware wallet security promises concentrate on keys never leaving the device, but this breach exposed a different attack surface entirely: order records and delivery addresses. They touch no on-chain asset, yet they link a real name, a home address and a known holding to a single list, and they render an unverifiable data-retention claim hollow.
Mastercard announced on October 19, 2026 a new security tool aimed at screening stablecoin transactions for fraud and sanctions-related risks.

Key Facts Sports-event prediction-market operators Crypto.com and Novig have filed suit against Missouri financial regulators to challenge the state’s cease-and-desist orders on sports event contracts. Kalshi, Polymarket, Robinhood and Underdog, which received similar orders, have held off on litigation according to court records. The core legal question is whether sports-event contracts are sports betting under Missouri state law, or derivatives trades under the federal commodity-futures regulatory framework. The case is widely viewed as a marker in the broader US state-versus-federal clash over how to classify sports prediction markets. ...
A U.S. federal judge denied on October 16 a joint motion by Gemini Trust and the CFTC to vacate a prior $5 million settlement, raising the bar for crypto firms seeking to unwind regulatory consent decrees.
According to multiple blockchain security and research firms, the crypto industry lost $768 million to hacks in September 2026, the worst single-month figure of the year, with NEAR Intents and Bitget among the major victims.

The US Department of Justice announced on September 15 criminal charges against two Robinhood engineers, alleging that between 2025 and 2026 they used inside information about the company’s upcoming crypto asset listings to take front-running positions on Hyperliquid decentralized perpetual contract exchange, with illegal profits potentially reaching several million dollars. This case represents the first criminal charge by US judicial authorities for insider trading conduct on a decentralized finance (DeFi) protocol, and will have profound effects on DeFi regulation, on-chain transaction privacy, and US crypto industry compliance architecture.
The US Senate’s cloture vote on September 15 on the CLARITY Act failed to clear the 60-vote threshold needed for passage, marking a significant legislative setback for this key bill that the crypto industry had long awaited. The core obstacles to passage were the ethics controversy over President Trump’s family crypto wealth and the long-standing partisan divide over the regulatory boundary between the SEC and CFTC. The result will directly affect compliance expectations of US-based crypto firms, market structure choices of stablecoin issuers, and the pace at which major global economies borrow from each other’s crypto legislative paths.
The US House Ways and Means Committee released a sweeping crypto tax bill ahead of Wednesday’s markup, establishing tax treatment rules across crypto payments, stablecoins, mining, and staking, while introducing a $10 de minimis exemption for small crypto payments. The bill will shape US crypto industry compliance costs, tax architecture, and retail crypto payment adoption, and may become a baseline text for subsequent Senate legislation and bipartisan crypto legislative negotiations.
Senate Republicans on September 14 released the ‘final draft’ of the long-pending Clarity Act for digital assets, while the White House confirmed that President Trump has accepted most of the bill’s ethics provisions. The new draft makes significant adjustments to digital-asset classification, the allocation of regulatory authority between the SEC and CFTC, stablecoin reserve requirements and disclosure of conflicts of interest. Industry analysts say the release breaks a multi-month stalemate that had previously been described by industry observers as a Schrödinger-style legislative limbo, and could clear the path for a full Senate vote in the coming weeks.
