Tangem Portfolio Viewer

About

Tangem Portfolio Viewer lets you check any Tangem (EVM) wallet’s coins and tokens with live USD values — read-only, with no keys and no signing.

WHAT IT DOES
• Portfolio balances across Ethereum, Arbitrum, Optimism, Base, and Polygon
• Live USD values via public Blockscout explorers
• Recent addresses and preferences saved locally on your device
• Dark / light / auto theme
• Full dashboard view in a dedicated tab

PRIVACY & SECURITY
• Read-only — never asks for private keys, seed phrases, or passwords
• Wallet addresses are sent only to public Blockscout APIs for balance lookups
• Recent addresses and settings stay on your device

OPTIONAL FEEDBACK
Tangem Portfolio Viewer may show an optional anonymous survey to help us prioritize improvements. Surveys only ask about your experience with the extension — feature preferences, usage habits, and suggestions. Surveys never request sensitive information. You can disable surveys anytime in Settings, or simply dismiss them with the skip button.

PERMISSIONS
• Storage — theme, chain tab, and recent addresses (local only)
• Alarms — periodic check for optional survey settings
• Blockscout hosts — read-only portfolio data
• api.tangemview.com — optional anonymous survey config and responses only when you submit

This extension is an independent community project and is not affiliated with, endorsed by, or connected to Tangem AG.

For portfolio viewing only — not a wallet, not financial advice.
