RISK

Why wallet_refreshUtxos is rated Medium

This tool modifies wallet state by syncing and internalizing UTXOs — it writes/updates data in the wallet. While it involves blockchain/financial context, it does not move money or commit financial obligations; it only imports/classifies existing received funds into the wallet's internal state. No irreversible deletion occurs. Write is the most appropriate category.
