Arbitrum Bridge TVL Rises to $3.5B; Analysts Flag Moderate-High Liquidity Risk

·1 views

A technical security report assesses the Arbitrum Bridge, which holds roughly $3.52 billion in total value locked, up about 4.2% over 30 days and 12.7% over 90 days. Around 84% of that value sits in canonical custodial contracts, with the remainder spread across user escrow contracts and third-party liquidity providers. The analysis rates the bridge's overall risk moderate-high, at 6.8 out of 10, citing economic attacks such as mass exits and governance-related upgrade risks rather than code-level flaws. The main vectors identified include fraud-proof exploits, sequencer collusion, governance upgrade attacks, and AMM-manipulation-driven liquidity drains.

Developer Shares Lessons from Shipping Three AI Side Project MVPs

A developer describes building over a dozen AI side projects, of which only three reached real users within two months.

Their second project, a tool that extracts decisions from Slack conversations, was built in 48 hours as a single API call and attracted sixteen users in its first week. The developer concludes that stripped-down, "sad path" versions that solve a concrete problem matter more than sophisticated infrastructure, and reports modest API costs for the projects.

Inserting Records with JooqTemplate in Java

JooqTemplate is a library that lets developers insert database records without code generation or XML configuration. Its setup involves adding a Gradle or Maven dependency and autowiring the template into a class. Records are inserted by passing a Map of field names and values to the insert method, which returns 1 on success. Fields left unset are written as null, and JooqMaps helpers can convert camelCase beans into snake_case maps, optionally preserving null values. Passing an empty map still inserts a record with default or null fields, while a null map or unknown table name triggers an exception.
