Owlio — DeFi Portfolio Tracker

Your portfolio across every wallet. Data never leaves the browser: there is no server side.

Owlio shows what you actually hold — across Ethereum and its L2s, BNB Smart Chain, Bitcoin, Tron, TON and Solana — in a side panel that stays open while you browse. There is no server. No account, no sign-in, no database. Your addresses and your portfolio live in this browser's storage and nowhere else, because there is nowhere else for them to go. That is not a privacy setting you can weaken — it is how the product is built. WHAT YOU GET • One portfolio across 15 networks. Add an address once; every network that address is valid on is read automatically. • Tokens, NFTs and DeFi positions on separate tabs — each honest about what it knows. • Value over time: a portfolio chart with 1W / 1M / 1Y / All periods, and a "what if I had just held BTC" benchmark line over it. • Transaction history, downloaded in the background, so the chart reaches further back the longer Owlio runs. Public explorers go down from time to time; when one does, the Data status screen names the network it could not read instead of quietly showing you less. • Privacy Mode: one tap hides every number, for when someone is looking over your shoulder. • Export and import your setup as a file you control. Wipe everything in two clicks. • Interface in 10 languages, picked up from your browser.
