How It Works

01

Stake Your Claim

Companies post verified bounties with pre-funded escrow. Every dollar is locked before it hits the board.

02

Hunt the Vulnerability

Researchers pick their targets. Each bounty includes scope definitions, test credentials, and safe harbor agreements baked in.

03

Submit Your Proof

File your report with full reproduction steps, impact analysis, and remediation advice. Our triage team reviews within 24 hours.

04

Collect the Bounty

Accepted reports trigger immediate payout from escrow. Wire, crypto, or platform credit.

We found three critical vulnerabilities in our payment stack within the first week. Deadlock paid out $87,000 to the researchers before our internal team even finished their coffee.

Field Reports from Hunters & Clients

I left HackerOne after six months of pending payouts. First bounty on Deadlock, paid in 19 hours. This is how it should have always worked.

Our previous bug bounty program attracted noise. Deadlock's escrow model means only serious researchers engage. We went from 200 junk reports a month to 12 actionable findings that actually made our platform safer. The ROI is incomparable.

Made $140K last year hunting exclusively on Deadlock. The scope docs are clear, triage is fast, and there's none of that "informative, won't fix" nonsense.
