Security Report Flags Yield Integration Risks in Arbitrum Bridge Holding $3.3B

0
·1 views

A DeFi security research team published an assessment of the Arbitrum Bridge, which connects Ethereum and the Arbitrum layer-2 network and holds roughly $3.3 billion in total value locked. The report examines how the bridge's capital could be deployed for additional yield while preserving security. It identifies risks including a seven-day withdrawal challenge window, upgrade and admin control by a DAO-held multi-sig, and concentration of funds in a single escrow contract. The authors rate the overall risk posture as moderate-to-high, scoring it 7 out of 10, with the lack of a dedicated yield-integration layer as the most significant exposure.

Phone validation API results need distinct handling for valid, unknown and failed checks

A signup form that treats every phone-check result as pass or reject can wrongly block users during outages or on unanswerable questions. The article presents a dependency-free Python fixture with four branches (normal, unknown, provider_failure, otp) that returns fixed outputs for testing signup logic without credentials or network calls. The free Basic Lookup route does not return line type, ownership, reachability or OTP delivery, so the design must not rely on those fields. The proposed design maps valid results to continuation under the team's own policy, unknown results to review or an existing OTP step, and provider failures to bounded retries before review. Questions the route cannot answer are handed off to a separate OTP provider the team already operates.

Canva Launches Brush, an AI Model That Edits Designs, Claiming 46% Lower Cost per Edit

Canva released Brush on 29 October, eight days after its Craft image-generation model, to handle refinements to existing designs. Built by Canva Research, the vision-language model is available now to Canva Pro subscribers within Canva AI, with wider rollout planned later. Canva reports it runs 69% faster and 46% cheaper per edit than its previous design agent, though the company has not published its test method or outside benchmarks. Brush works through an agentic loop that makes changes, inspects the result, and adjusts, while keeping every element editable by the user. The company says the aim is to apply requested changes without disturbing the rest of the design.

Audit of 80 Shopify and WooCommerce product pages finds gaps in shipping and return schema

A technical audit examined public HTTP responses from 100 online stores, of which 80 had readable product pages. Most of those pages lacked key structured data, with 78 of 80 missing shippingDetails and 76 of 80 missing hasMerchantReturnPolicy in their Product JSON-LD. The author notes that Offer fields like price and availability were generally present, while native files such as /llms.txt were largely absent unless manually configured. The study is explicitly limited to a non-random sample and does not mean stores lack shipping or return policies on their websites. The author also promotes a read-only tool, CitedCart, that lets store owners inspect their own markup.
