ZK has broken out of the crypto bubble. Google Wallet, Cloudflare and EZKL now ship zero-knowledge proofs in production. Here’s what that looks like in the real world: hexens.io/blog/zk-usecas…

You can now transfer encrypted USDC, USDT, Bitcoin, and more using Encrypted on the Avalanche🔺 C-Chain. It provides confidential account balances and token transfers—no one can see how much you’re transferring. The lack of this feature was one of the biggest blockers to

I'm a Security Engineer with 5+ years of experience in Web Security and Bug Bounty. Actively looking for new opportunities in cybersecurity (engineering or triage roles). Feel free to reach out or connect, happy to share my CV.

Thank you Remedy for the fantastically unique Remedy CTF 2025 merch! First blood cards are 🔥 Looking forward to participating or collaborating in the task development next year 👀

1/ How I found 4 critical bugs in 3 months and reached All-time #9 on Immunefi 🧵

In this talk, I presented our approach and architecture for MLIR-based #FHE compiler and ecosystem designed for privacy-preserving computation using fully homomorphic encryption (FHE). youtube.com/watch?v=9dvVxb…

Early FHE was a math marvel but a compute nightmare. Modern schemes like BGV/BFV/CKKS flip the model, packing vectors with CRT and unlocking SIMD via Galois automorphisms. Here’s how the math makes FHE practical: hexens.io/blog/simd-in-f…

We are pleased to share the first edition of the FHERMA Cookbook — a collection of modular #FHE components and AI models, developed through fherma.io challenges. eprint.iacr.org/2025/1302 The Cookbook is designed as a practical, extensible resource for

Security on @Arbitrum just got to a whole other level! After 30+ audit firms applied and underwent a rigorous evaluation process, we’re excited to share the final list of top-tier auditors selected for the Arbitrum Audit Program.

New Bug Bounty on Remedy: Valantis Labs is offering $200,000 to security researchers to help secure its modular exchange protocol. Bounty details are here:

Hexens is excited to have the support of EF Ecosystem Support Program. Wait for what’s coming!

1/5 We launched Alpha Challenge a year ago to discover hidden gems. After valuable lessons learned, bringing back a CTF alternative focused on onchain research was a no-brainer. Welcome to the Wintermute Alpha Challenge 2025.

Hexens has completed a security review for Logarithm Labs. The audit assessed the Metavault, focusing on deposit/withdrawal handling, allocation management, and ERC-4626 integration. Their new upgrade makes vaults easier to use while preserving strong asset management. Read the

We’re proud to be collaborating once again with our trusted security partner, hexens this time to safeguard our Metavault. The future of DeFAI is closer than ever.

FHE-Powered Privacy at Production Speed. Our new deep-dive article on Generalized BFV explains why this new scheme looks promising: how polynomial plaintext modules leads to more throughput and how it actually scales. Read the full article: hexens.io/blog/gbfv
