Publisher Evidence

Limited evidence

[email protected]

Publisher identity, store signals, distribution reach, and warning signals used for context. Treat this as supporting evidence, not a clean bill of health.

Chrome does not expose the same publisher verification data as IDE stores, so this score is deliberately conservative.

About This Extension

BaseDex follows cryptocurrency prices, markets, and wallet balances. Follow the coins you care about and convert between them. Check network fees, explore market sentiment and activity, and add an address to see balances, tokens, and recent activity. Save a price alert and Chrome notifies you on this device. Currency, language, alerts, and wallets stay in this browser. BaseDex does not ask for a seed phrase or private key. BaseDex is an independent product. It is not affiliated with Coinbase, Base, or any exchange. Market and chain figures come from public data and can be delayed. What BaseDex includes Prices Search any coin and keep a personal list of the ones you check. Each row shows the price, the daily change, and a small chart. Pin the coins you want at the top. Open a coin for a longer chart and save a target price. When that price is reached, Chrome shows a notification on this device. Convert an amount from one coin to another, or between USD and EUR. Markets A daily strip shows a sentiment reading and current network fees. Refresh updates the figures while you are looking at them. Explore Browse markets by leading coins, trending coins, gainers, losers, and categories. Open DeFi to search protocols and see value locked by network. Open NFT to search collections and sort them by rank, trend, volume, gainers, or losers. Wallets Add a name and an address. BaseDex reads that address across the supported networks and shows one portfolio total. Open a wallet to see holdings, recent transfers, NFTs, and an average buy price you can save for your own reference. Settings Choose USD or EUR, a dark, light, or system appearance, and a compact list. The language can follow the browser or be set directly. Privacy Policy, Terms of Use, About, and Contact are inside the extension. Open the side panel to keep BaseDex beside the browser, or expand it into a full tab. What you can expect BaseDex is a place to follow cryptocurrency prices, look through markets, and check wallet balances without creating an account. What you save stays on this browser. Figures are informational, markets move quickly, and displayed data can be delayed or unavailable.
