Finally, a win 🥇

Won the @Rain__Protocol USDr contest on @HackenProof among 154 researchers.

Found 9/9 highs and 12/13 mediums.

Each submission cost $5 to file. I sent 79, so $395 out of pocket. Worth it? Don't care tbh, I just wanted to find as many bugs as possible. LFG!

Honored to share the board with Otter11, @KodeKloner2, @0xfrsmln and @anchabadze, congrats!

Yeah, private contests like this are the best setup for a company. Everyone sticks to their own work, and there’s almost no spam or noise.

Yesterday we published our latest audit report.

As part of the engagement, we ran a private SpecSiege competition on a tokenised bond platform.

The setup:
• Capped at 50 researchers (The winner was @heavyw8t_)
• 30+ actively competed (submitted at least one finding)
What a capped, curated contest delivered:
- Very little spam. The few who spammed were banned.
- Judging stayed manageable. Results reached the client in under 3 days.
- A few Medium and many Low severity findings, adding another layer of review on top of the protocol's existing security work.

A short competition window, a focused group of researchers, and solid results.

Want a curated SpecSiege competition alongside your next audit? DM us.
