I hunt bugs on/off-chain. Mostly EVM (Solidity), Cosmos SDK + cosmwasm, Rust, Go, Move,..

Hattrick has been achieved! 3 Cosmos SDK contest wins in a row 🥇

Years of grinding Cosmos audits paid off. Success does not (always) come overnight, guys.

Shoutout to @code4rena, the amazing contest sponsors, and everyone involved!

Especially the amazingly skilled @3DOCsec, who volunteered to partner up with me. Thanks!

[Code4rena @code4rena]

The results of the $80,000 Initia Cosmos competitive audit are in!

Congratulations to everyone who submitted valid findings, especially to @bernd_eth for securing over half of the total prize pool along with 7 solo high-risk findings submitted!

Much respect to @initia for their unwavering commitment to the highest security outcomes.

200 🐐s securing this space! I'm proud to be selected as one of them.

Let's get to work - duty calls.

[thedao.fund @thedaofund]

The final 100 ETHSecurity Badge holders are in!

That brings us to 200 security experts, guiding how TheDAO allocates its funds and also coordinating behind the scenes to make Ethereum safer.

Big thanks to everyone who engaged with the process and helped shape it, and to @bonfiresai for building the tooling that made it possible.

@0xSorryNotSorry That's such a nice catch!

[BΞrnd @bernd_eth]

@octane_security Impressive, congrats! 👏

[BΞrnd @bernd_eth]

@bailsecurity I’ve seen it too. Some big Tier-1 audits were weak, but ofc it depends a lot on which team they put on the job.

One time it's great, next time meh.

Projects should stop just hunting for the famous name on the report. The real deep quality check matters much more than the logo.

Happy to end 2025 in 3rd place on the @code4rena leaderboard!

[Code4rena @code4rena]

1,206.

That’s how many awards were distributed to C4 Wardens in 2025.

Thank you to all of the Wardens who committed their time each day to making C4 the place where the best researchers compete.

And a special shoutout to the Wardens who finished in the top 10 on the C4 Leaderboard over the past 365 days!

It is @SecurityOak who brought me into this industry, gave me a chance to prove myself, and trusted my abilities from the very first audit. Thank you!

It's great to see how things have grown and matured, and I'm proud to work alongside 50+ chad auditors.

Cheers to the future!

[Oak Security @SecurityOak]

We’ve had a glowup!

Since 2017, we have conducted over 600 audits.

Today, we offer everything from protocol design to operational security, training, economic advisory, and pentesting.

New look, new services.

The same uncompromising quality!
