Why whitelists exist
Projects gate early access to (1) reward genuine early community members, (2) throttle demand so infrastructure and liquidity aren't overwhelmed at launch, and (3) collect a committed test cohort whose feedback arrives before the noise of a public launch.
Sybil filtering
One person, many wallets. Teams fight sybils with proof-of-humanity checks, wallet-age and activity heuristics, social-account linking, and clustering analysis of funding sources. Typical launches discard 20–60% of raw signups as duplicates or bots.
Your real odds
If W spots are raffled among Q qualified entrants, your probability is simply P = min(1, W / Q). Completing optional tasks usually multiplies your ticket count — doing 3× tasks in a weighted raffle triples your expected chance, not your guarantee.
Red flags
Be suspicious of whitelists that ask you to (1) send funds "to verify", (2) sign blind transactions or token approvals, (3) share seed phrases — never legitimate — or (4) install unknown wallets. A real allowlist only ever needs a message signature or an address.
