[asymmetric research @asymmetric_re]

Asymmetric Research and @osec_io have established a shared leadership structure that aligns both teams while each continues to operate independently.

Full details below.

@markdsouza_d go ahead sir

[Anthony Tsuei @anarcheuz]

@mmmoiez Frontend and Backend. I've replied to your DM.

[Anthony Tsuei @anarcheuz]

We're looking for a full stack Go dev in any of the US timezones, if you're interested please DM me. Position is remote with good benefits. A background in security is preferable.

[Anthony Tsuei @anarcheuz]

@x_james_t 🤝

[Anthony Tsuei @anarcheuz]

@chard_boi They are now :)

[Anthony Tsuei @anarcheuz]

@akashgo_012 Postgres and the standard go http. But there are also a bunch of custom tech.

Boredom > Beauty: Why Code Quality Is Code Security by @johnsaigle

Some of the most devastating vulnerabilities stem from complexity, inconsistency, and chaos. This post explains why predictable, well-formed code is the foundation of security.

Thank you to everyone who stopped by the Dev Cave during Scale or Die.

It was a privilege to host a space like this for builders. Huge thanks to the entire @SolanaConf team and everyone who made this possible.

We’ll be around the rest of the week! Reach out or come say hi.

[Jonathan Claudius @claudijd]

Lots of under-appreciated value in differential fuzzing campaigns, especially for regression safety.

New blog post: Navigating Vulnerabilities in Solana CPIs, by @dooflin5. It breaks down how unchecked programs, signer privileges, and account handling pitfalls can lead to exploits—and how developers can design defensively.

[asymmetric research @asymmetric_re]

We'll be playing a big role at @SolanaConf this year:

- Speaking on designing holistic security programs for high-stakes projects
- Hosting a dedicated space for security-focused builders
- Awarding a few travel grants

Details to come. Accelerate.

[Firedancer 🔥💃🏻 @jump_firedancer]

We’re seeing confusion around @Firedancerio — to clarify:

❌This is not an official account.
✅Official Comms: @jump_firedancer

Stay safe out there.

Announcing AR’s Intern Program

We’re launching an intern program that’s hands-on, high-impact, and fully remote.

Looking for security research types who are curious, skilled, and ready to work on security challenges that matter ↓

[Jonathan Claudius @claudijd]

It takes a village…

[asymmetric research @asymmetric_re]

🔥💃 We’re now running Firedancer v0.3 on mainnet! Validators running Firedancer benefit from cutting-edge security, reliability, and performance, improving Solana's liveness and safety.

Firedancer is running a public audit contest on Immunefi before its v0.1 mainnet launch. A completely new C codebase parsing untrusted network input, featuring a handwritten QUIC implementation and multi process sandboxing. No crypto background needed. DoS is in scope. 1M$ prize pool.

Fun vulnerability for my first big bug while at Asymmetric Research. Worth the read if you like weird vulns in weird things!
