ContractScan runs 5 security engines in parallel — Slither, Semgrep, Mythril, Aderyn, and AI — on Solidity or Rust/Near contracts. No CLI setup. ~30 second results. Free QuickScan: no signup. $4.99 Deep Scan: full 5-engine report. $59/mo Pro: unlimited + CI/CD. 5 real-world threat intel sources: 686 DeFi exploits, Solodit, Code4rena, Sherlock — all integrated. Goal: detect every vulnerability type ever exploited in production.

Instant security analysis for Solidity contracts. No CLI setup. AI-powered reports with fix guidance.

Upload a .sol file or paste a GitHub URL. Get a structured vulnerability report — free, no signup needed. Enter your license key to unlock unlimited scans or additional scan credits. Industry-standard Solidity static analysis. Data flow, CFG traversal, and storage slot inspection. Symbolic execution over EVM bytecode. Finds paths no linter can: integer overflows, assertion violations, unprotected ether. AST-aware pattern matching. Fast, high-precision rules for known vulnerability classes written by ContractScan. Rust-based Solidity AST scanner from Cyfrin. Detects centralization risks, unsafe casts, and unused returns.

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
