Odaily reports that former Mt.Gox CEO Mark Karpelès stated that a Ledger hardware wallet he purchased from Malaysia was found to contain a suspicious module with a SIM card chip built in. The module was hidden in the screen padding area, and the device's outer packaging was intact.

Slow Mist Chief Information Security Officer 23pds analyzed that attackers may have connected the malicious module to the screen data cable to record the words displayed when the device generates seed phrases, and then used LTE or eSIM to transmit the data externally.

23pds pointed out that the secure element of a hardware wallet is mainly used to prevent private keys from being directly read, but it cannot prevent malicious hardware from capturing screen display content. Currently, the related attack mechanism remains a technical speculation and still awaits further verification.

Odaily News: Brazil's largest stock exchange, B3, is expected to launch a securities tokenization platform in the first half of 2027. The relevant tokenized securities will be interchangeable with traditional stocks and will share price and liquidity. The platform was originally scheduled to launch in the second half of 2026, but has now been adjusted to the first half of 2027.

Humberto Costa, Director of Products and OTC Strategy at B3, stated that tokenized securities will be issued based on existing assets and will not be primarily issued on the blockchain, and trade settlement will still follow the current two-business-day settlement mechanism. Whether Brazilian Depositary Receipts and exchange-traded funds will be included in this infrastructure is still under evaluation.

B3 also plans to launch its own stablecoin and will apply to the Central Bank of Brazil for authorization to conduct digital asset operations and custody business. Round-the-clock trading and instant settlement still require approval from Brazilian regulators or the establishment of a new regulatory framework. (Bitcoin.com News)

Odaily News: Aero has published the token exchange terms and timeline for the merger of Aerodrome and Velodrome. The merger will launch on October 21 at 8:00 PM (ET), at which point token emissions on both legacy platforms will cease. Existing AERO can be exchanged 1:1 for the new AERO, while each VELO can be exchanged for approximately 0.044 AERO, with this ratio applying to both circulating and locked tokens. The VELO exchange ratio depends on the supply at launch, with Aerodrome holders allocated 94.5% of the new supply and Velodrome holders allocated 5.5%.

Existing veAERO and veVELO positions will be converted into new sAERO positions, with remaining lockup time carried over and rounded up to the nearest full week, and permanent locks converted to maximum-duration staking. Tokens will not be exchanged automatically; self-custodied assets must be processed through the Aerodrome or Velodrome upgrade portal, and users must first claim rewards and rebase and clear active votes. The new model will replace the original weekly voting cycle with real-time allocation, allowing sAERO holders to direct rewards to pools and earn yield as exchange revenue accumulates, with a 47-hour cooldown period initially in place for allocation adjustments. The merger was announced in November 2025, and developer Dromos Labs originally planned to complete it in the second quarter of 2026.
