New here? The Crypto, DeFi and DEX Volume tabs work right away, no setup. Stocks, ETFs, Portfolio and News show sample data until you add a free Finnhub API key — here's how to get one (about a minute). Keys and holdings are saved only in your browser.

How do I get a Finnhub API key?
Go to finnhub.io and click Get free API key (sign up with your email).
Copy the key shown on your dashboard.
Paste it into the Finnhub API key box above and click Save.
It's free (about 60 calls a minute). The key is saved only in your own browser and is never sent anywhere except Finnhub. It powers live data on the Stocks, ETFs, Portfolio and News tabs. A brand-new key can take a minute to start working.
Ledger — Crypto

Box size = category market cap · color = 24h change in that category's market cap · top 40 categories. Categories overlap (a coin can belong to several), so sizes don't add up to the total market. Data: CoinGecko categories.
Box size = market cap · color = 24h change · top 100 coins by market cap, independent of table sort/search.
Ledger — DeFi
Where the money sits across blockchains, how big stablecoins are, and the best-paying pools — from DefiLlama.

Yield pools shown
TVL = total value locked in DeFi protocols on that chain. Top 25 chains by TVL; 1d/7d/30d changes are calculated from each chain's daily TVL history.
USD-pegged stablecoins only (circulating supply). Price is the current market price versus its $1 peg.
APY = total advertised yield (base + reward tokens) and can change fast. High APY usually means high risk — thin liquidity, volatile reward tokens, or unaudited contracts. Raise the minimum TVL to cut the junk. Not investment advice.
Ledger — DEX Volume
Decentralized exchanges ranked by trading volume, not tokens — this tracks protocols (Uniswap, Curve, etc.), each shown with its category and native chains.

How do I get a Tiingo API key (for 3Y and 5Y returns)?
Paste it into the Tiingo API key box above, click Save, then click Get 3Y/5Y from Tiingo.
Free plan, with hourly and daily request limits. The key stays in your browser. Polygon's free plan only reaches back about 2 years, which is why 3Y/5Y come from Tiingo instead.
Ledger — News
Market headlines and news on the tickers you follow, from your Finnhub key.
Ledger — Portfolio
Track your own holdings against the live prices already being pulled on the other tabs.

Your holdings are saved only in this browser. Nobody else can see them, and each visitor starts with an empty portfolio. Example entry: Stock · AAPL · 10 shares · $150.00 per share · purchase date 2024-03-15. (Just an example — it isn't added to your portfolio.)
Optional: how do I get a Polygon API key (for stock and ETF history)?
Go to polygon.io (now also called Massive) and sign up for the free plan.
Open your dashboard, find API Keys, and copy your key.
Paste it into the Polygon API key box below and click Save.
Only needed for the value-over-time chart with stocks and ETFs, and for ETF returns. The free plan allows 5 calls a minute, so the first load is slow and then cached. Crypto history needs no key.
