Scoring philosophy
Each signal adds points to a base score of 0. Points are capped at 100. For verified safe wallets (known exchanges, public figures), the score is capped at 12 regardless of other signals. The score reflects on-chain behavioral risk, not moral judgment — a high score means caution is warranted, not that the wallet is definitely criminal.
