A big, heavily promoted bounty pool doesn’t mean you’ll ever see a dime.
The clearest proof of real security value for bug bounty customers is simple: money paid out to researchers.
Always has been. Always will be.
I scraped every directory page, every live program listing, every figure a crypto bug bounty platform has put in writing, all to give you the best overview of bug bounty platform impact ever written.
You'll find it all here.

Bitget has lost around $351.6M from its hot and warm wallets this evening, CEO Gracy Chen confirmed.
That makes this the largest crypto hack of 2026 so far, per @DefiLlama.
Bitget says user funds are safe and withdrawals are paused.
[SECURITY NOTICE] Bitget Hot Wallet Incident — September 24, 2026
At 18:31 UTC on September 24, 2026, Bitget's security systems detected unauthorized transfers from some of our hot wallets. Our security team activated emergency response protocols immediately.
What we have confirmed:
-Estimated funds affected: approximately $351.6 million
-Cold wallets remain fully secure. Bitget operates a three-tier wallet architecture — the breach contained only a portion of the hot wallet and warm wallet layers.
-User funds are safe. The full amount of this loss falls within the coverage of Bitget's User Protection Fund, which currently holds over $464 million
Actions we have taken:
-Emergency response team activated within minutes of detection
-Abnormal transfer addresses identified, flagged, and reported
-Withdrawals temporarily suspended as a precautionary measure, pending security review
-Law enforcement and on-chain security firms have been formally notified and are engaged
What this means for you:
-Your account balances are accurate and your assets are protected
-Deposits and trading remain fully operational
Withdrawals are temporarily paused and will be restored as soon as the security review is complete
-What comes next: We will provide updates on an hourly basis across this channel and all official platforms. A full incident report — including root cause analysis and corrective actions — will be published within 24 hours. We will not speculate on the attack vector until the investigation is complete.
Bitget has navigated multiple market cycles. We will not run from this. Every dollar and every decision will be accounted for, transparently and in full.
Updates will be posted here and across all official Bitget channels as they become available.
— Gracy Chen, CEO, Bitget

AI security agents are going to find many of the same bugs. That also means they could share the same blind spots. But how do you know what your agent keeps missing if you only test it in isolation?
Hunting on Immunefi shows you how your agent competes with other agents on real-world targets.
Immunefi Studio takes it one step further. Without submitting reports, you can see where it performs well, where it falls short, and what you need to improve to make it more accurate and efficient.
If you're building or working on an AI security agent, send us a DM.

Security researcher Naresh_Kandula identified the Most Valuable Finding in the @QuantusNetwork Audit Competition.
Report ID: 88609
Here's what Quantus had to say:
"The report identifies a high-security account bypass that allows an attacker with a compromised key to bypass the guardian delay and drain almost the entire account balance in a single block by attaching a massive tip to a failing whitelisted call."
Congrats on the finding, Naresh!
