Main news drivers

Ledger and Coldcard security issues

Cointelegraph reports that Ledger confirmed an unauthorized hardware implant and said losses may exceed $86 million. Ledger said the incident appeared to be isolated to a single reseller and its Southeast Asian market. Separately, Cointelegraph says hardware wallet maker Coldcard is investigating how a phishing link appeared on its X account. The company told users not to visit or interact with the link.

CFTC sets out prediction market rules

The US Commodity Futures Trading Commission has proposed two measures on event contracts. According to Decrypt, a proposed rule would fold contracts tied to sports, politics, culture and weather into the "swap" definition, while an interim rule excludes casino-style gambling. Cointelegraph notes that the measures set the stage for a potential US Supreme Court battle over federal and state jurisdiction.

IMF on tokenized stocks

CoinDesk reports that the IMF found real demand for tokenized stocks, with investors using them for smaller and after-hours trades. The IMF also said the market is still volatile and illiquid, and that liquidity, legal rules and settlement systems have not caught up.

Zcash prepares quantum defenses

Decrypt reports that Zakura, a Zcash full node developer, expects hash-based signatures to land in Zcash in January. It is also rolling out a privacy tool for rotating transparent addresses this week.

What to watch next

• Ledger follow-up: any update on the size of losses and whether the implant stays limited to one reseller, per Cointelegraph.
• Coldcard: the company said it will share further verified updates on the phishing link.
• CFTC rules: the proposed and interim rules on event contracts, and any jurisdiction fight with states that Cointelegraph says could reach the Supreme Court.
• Zcash: Zakura's address-rotation privacy tool this week and hash-based signatures targeted for January, according to Decrypt.
• Sentiment: whether Fear & Greed holds in the low 60s after its slide from 73 earlier in the week.
