Four surfaces, one number
The score reads four groups of public on-chain signals. Age and activity depth: an address with years of steady history behaves differently from a fresh burner, and scammers overwhelmingly farm fresh burners. Token spread: a wallet carrying a pile of unsolicited airdrop and dust tokens has a wide phishing surface, because every one of them is a lure waiting for an approval. Approval surface: standing permissions to contracts, especially unlimited ones, are the single most common drain vector. Balance concentration: how value sits across assets hints at whether one signature can take everything.
Each surface contributes to a 0-1000 total. The bands map to ranks: S is rare and boring in the best way, A and B are typical healthy wallets, C means real findings worth acting on, D means the wallet has open doors an attacker would enjoy.
Why heuristics, not verdicts
The score is a heuristic, and we say so on every page. It cannot see intent, it cannot see your device, and it cannot know that the sketchy approval is your own testing contract. What it can do is compress hours of manual explorer reading into ten seconds and point at the specific findings that produced the number.
That is why the findings list under the score matters more than the letter. An A-rank wallet with one unlimited approval to an unverified contract still has one concrete task to do today. The rank sets priority; the findings set the to-do list.
What moves the number
The fastest way up is closing surfaces: revoking stale approvals, ignoring dust rather than touching it, and letting an address build history instead of rotating burners. The fastest way down is the opposite pattern, plus events the monitor is built to catch: a sharp balance drop or a fresh cluster of risky approvals.
Nothing in the scoring rewards holding any particular token, and no scan can change your score by itself. The read is passive: public data in, signal out. No signature, no connection, no permission at any point.
