Questions

Which 500 hashes do I sponsor?
When you click the button, ThreatChain picks 100 unpublished high-severity hashes from its corpus and locks them for your wallet. You'll see a preview of 10 before signing, and the full list on your contributor page after the tx confirms.
Why $5?
$5 clears every CEX withdrawal minimum and every L2 bridge minimum. You pay 5 USDC plus ~$0.30–1 gas on Arbitrum — total well under a cup of coffee. The $5 flows directly to the treasury address fixed at deploy; no middlemen.
Can I transfer the badge?
No. It's soulbound (ERC-5192). Your contribution is tied to your wallet forever. Think of it as a reputation anchor, not a tradable collectible.
What happens if I sponsor 10 times?
You still have one badge — but it upgrades. 1,000 hashes moves you from Hunter to Slayer. 5,000 to Sentinel. Each tier is visible on-chain and on your contributor page.
Can ThreatChain take my money?
No. The contract is immutable — no admin functions, no setters, no upgrades. USDC goes directly to the treasury address fixed at deploy time. You approve exactly 1 USDC per tx, not infinite, so even a compromised site can't drain you.
