What is Device Fingerprinting?
Device fingerprinting identifies a visitor by the combination of attributes their browser and device expose, rather than by cookies or IP address alone.
How it works
Signals like canvas rendering, installed fonts, timezone, and hardware concurrency combine into a stable identifier that survives proxy rotation.
Why it matters for web3
Fingerprints let you recognize the same operator across thousands of IPs, which is where scrapers and botnets are weakest. For your community, that means your allocations stay protected and real holders get a fair experience.
How ValidatorWall detects it
ValidatorWall scores every request against behavioral, network, and device signals, so automated patterns surface even when they imitate real real holders. Suspicious sessions get challenged or blocked before they reach your community.
