A wallet score is a number or grade assigned to a crypto wallet address after analysing its on-chain activity. There is no single standard, and the term covers several uses. Compliance firms give addresses risk scores based on links to hacks, scams, mixers or sanctioned entities, which exchanges use in transaction monitoring and when deciding whether to accept a deposit. Projects use activity or reputation scores to decide who qualifies for an airdrop and to filter out farms of fake accounts. Some lending experiments use wallet history as a stand-in for a credit score. Each provider uses its own method, so the same address can score differently in different tools. Scores can wrongly flag innocent users who received tainted funds, and they raise privacy questions. Also see blockchain analytics.
