And it will. Join us.

This summer don't touch grass SR

You can also pledge behind them and earn whenever they get a payout: immunefi.com/hacker-pledgin…

25,000,000 IMU now pledged behind security researchers. People aren't just cheering for whitehats anymore. They're backing them with capital.

27k for the bug-finding agent immunefi.com/s/ss/?severity…

Well, another feedback loop closed, 5k payout. I just found a confirmed bug on @immunefi #immunefitribe immunefi.com/s/ss/?severity…

@Haxatron1 congrats sir!

@Haxatron1 that's like 1,2,3...27 thousand!

So many new security researchers who joined in the last 6 months are absolutely crushing it.

This SR joined Immunefi in December 2025. This week he found a high-severity vulnerability before anyone could exploit it. Dead men tell no tales, but apparently they find bugs. Congrats @RebelsRunways!

This Security Researcher has earned $3,612,409 hunting bugs on Immunefi. 32+ live critical vulnerabilities found, saving hundreds of millions of dollars from hacks. Meet @lonelysloth_sec, ranked Top 5 all-time on @Immunefi. We asked him how he does it. One practical bug bounty strategy that has helped him find better bugs: "Protocols share a lot of code. When you find a bug that isn't exploitable, take some times to check if the same bug doesn't show up in other protocols where it might be. Study families of protocols, compare their code. Things are getting more and more interconnected." The habit, routine, or mindset that has made him more consistent as a researcher: "Curiosity. I don't rest until I understand every part of the system. Even if I end up not finding a bug, I want to understand it." A memorable bug or win, and what helped him find it: "I have quite a few public disclosures, but for one project between '24 to '25 I got paid for 9 critical bugs. I spent months getting to know every last detail of their (very large) code base. More than a breakthrough it was about persistence in one target, learning everything about it, and using everything I knew on it. They weren't the highest paying bugs I found, but I'm very proud of that achievement. I still find bugs in that project." His advice to a researcher trying to level up or land their first bounty: "Find motivation in the journey, because it's a long one. Enjoy understanding something that previously was mysterious to you, the feeling of knowledge accumulating. It compounds and will eventually lead to your bounties. Keep trying -- you need to give luck a chance to find you."

@JB_Xponential @lonelysloth_sec It really is about persistence and curiosity

Many newcomers think bug bounties are about finding a clever exploit. In reality, they're often about persistence. Reading every contract, tracing every state transition, understanding every invariant, and refusing to leave unanswered questions. Curiosity compounds, and eventually the bugs reveal themselves.

@zzykxx @lonelysloth_sec beautiful sentence indeed

@immunefi @lonelysloth_sec "you need to give luck a chance to find you", that's a beautiful sentence

@MartinMarchev @lonelysloth_sec he really is

@immunefi @lonelysloth_sec A true legend 🫡

@asen_sec @0xfrsmln great work!

@0xfrsmln @immunefi 🔥🔥 good work ser

I just found a bug and got paid on @immunefi #immunefitribe immunefi.com/s/ss/?severity…

Count me in for SR Summer

@MVadivalan incredible work

I just got my 1'st four digit payout 🥳 Thank you @immunefi I just found a bug and got paid on @immunefi #immunefitribe immunefi.com/s/ss/?severity…

@immunefi First two tasks completed 🫡

@immunefi I'm locked in

You're going to waste the summer. Not because you're lazy. Because summer makes losing momentum feel harmless. And by the time September shows up, "I'll lock in soon" has already cost you 3 months of your life. This summer, use it. Today, we're launching SR Summer 🏖️💻 A challenge for security researchers who want to spend this summer turning their skills into actual money. The goal is not just to tell you to "hunt harder." It's to help you get better at the parts of security research that actually affect your results. Which programs should you spend time on? How do you choose targets with a higher chance of meaningful findings? How do you structure your research process? How can AI help you move faster? How do you write reports that are easier to review, and more likely to communicate impact clearly? That is what SR Summer is about. The full breakdown is below. Don't read it in September.
