first_img Doubao has been exposed for advancing a personal assistant product, internally codenamed Spell

On September 29, according to a report by Phoenix Technology citing Sina Technology, Doubao, a subsidiary of ByteDance, is advancing its product planning in the personal assistant direction. Insiders revealed that continuing the strategy of last year's Doubao mobile assistant in the personal agent direction, internal testing of related exploratory products began in April this year, codenamed Spell, mainly led by the Doubao mobile assistant team, but has not been officially announced due to reasons such as the release of the Doubao mobile phone.The insider stated that as personal assistant products like Muse and Instinct have gained attention overseas, Doubao is also accelerating the external release of personal agent capabilities, planning to integrate the Spell project more deeply with Doubao products. The new product will be jointly managed by the Spell project and the Doubao dialogue team, and it is expected to be launched externally soon. According to "Big Factory Daily," the Doubao product line has received a new task during the Mid-Autumn Festival, requiring a rapid reconstruction of a product that benchmarks Muse, with a beta version developed by September 30 for internal testing, involving the entire Doubao product line and multiple upstream and downstream teams in this holiday development.Previously, the technical preview version of the Doubao mobile assistant made its debut in December 2025, first launched on the ZTE Nubia M153 engineering prototype. In September 2026, the consumer version was officially released, landing on the Nubia NaviX Ultra model. Reports indicate that Spell can be seen as Doubao's extension of the personal agent capabilities accumulated on mobile devices into an independent application form.

first_img Cross-chain trading platform Relay API exposes pending transactions, which will compensate approximately $312,000

Co-founder and Chief Operating Officer of the cross-chain trading platform Relay, Jason Maier, stated that the team discovered an issue with the Relay API over the weekend, which exposed pending transaction information before trade execution. MEV seekers exploited the pending routing status to infer on-chain paths and front-run trades before order execution, resulting in worse execution prices for users trading through Relay.This activity occurred from September 12 to September 26, primarily concentrated from September 23 to 26. Seekers profited approximately $136,000 from this, affecting around 5,600 users, with a median impact of $11.88. Relay will pay a $50,000 bounty to Outputlayer for reporting the issue and will automatically compensate affected users without the need for applications; funds will be directly sent to wallets, with a total compensation amount of approximately $312,000.Jason Maier stated that MEV can arise through public mempool exposure, order detail inference, malicious participation in auctions, or data gaps between service providers, and protecting a single link in the transaction path is not sufficient. He mentioned that the team will continue to enhance the execution quality and privacy of the entire transaction path and called on security researchers to report vulnerabilities when discovered.
