Crypto market heatmap: coins, narratives and ecosystems on one treemap.

By default, token size on the heatmap is proportional to market capitalization. Bitcoin and Ethereum occupy the largest rectangles because they have the highest market caps, and smaller-cap tokens appear as smaller rectangles. This sizing matches each token's visual weight to its economic significance. The Size control can also size by open interest, 24h spot volume or equal area.

With price change selected, green is a gain and red a loss over the selected window, and intensity scales with the move against the board's own range (full color at no less than 5% on 24h and longer windows). Neutral gray means little change. The other metrics have fixed neutral points: 0% APR for funding, 50 for RSI and 1x for relative volume, so green always means above neutral. This color gradient makes extreme movers immediately visible.

Price change has 1-hour, 4-hour, 24-hour, 7-day and 30-day windows, opening on 7 days, and RSI uses 1H, 4H or 1D candles. Each window recolors every token based on its price change over that period. Comparing the 1h and 7d views often reveals useful divergences: a token that is red on the 1h but deep green on the 7d may be experiencing a healthy pullback within a strong trend, while a token green on 1h but red on 7d may be a dead cat bounce.

The heatmap data is rebuilt every three hours from CoinGecko and Sharpe's open-interest and funding data; the 1h and 4h price changes and RSI come from hourly perp candles. The page checks for new data every five minutes, and the legend shows when the metric on screen was observed.

The heatmap covers 15 narratives (DeFi, AI, Layer 1, Layer 2, Memes, Gaming, RWA, DePIN, NFTs, Privacy, AI Agents, DeFAI, Perp DEX, Prediction Markets and Exchange Tokens) and 20 blockchain ecosystems. Pick one to see its coins, or All narratives or All ecosystems for one tile per category. When several sector tiles turn deep green or red together, it signals broad-based sector rotation rather than isolated token moves.

The heatmap provides instant visual pattern recognition that tables cannot match. It reveals sector rotation (which sectors are gaining while others fade), relative strength (which tokens within a sector are leading versus lagging), and market breadth (whether gains are concentrated in a few names or broadly distributed). These patterns help identify where capital is flowing and which market themes have genuine momentum behind them.

Yes. The Market Heatmap is available free on Sharpe Terminal with no account required. Every universe, color metric, size mode and exclusion is accessible immediately. Heatmap data is also available through Sharpe's REST API and MCP server for programmatic access.

Crypto market cap is calculated as current price multiplied by circulating supply, the number of tokens actually in public circulation, excluding locked, burned, or unvested tokens. For example, Bitcoin's market cap = BTC price x ~19.7M circulating BTC. Market cap does not account for illiquid tokens, so it can overstate true tradeable value for assets with shallow order books. It is the most widely used metric for ranking crypto assets by size and the basis for sector indexing and dominance calculations.

Circulating supply is the number of tokens currently available to the public and tradeable on exchanges. Max supply is the hard cap on how many tokens will ever exist: Bitcoin's max supply is 21 million, Ethereum has no hard cap, and most altcoins publish a fixed or inflationary schedule. Total supply sits between the two: all tokens that exist today including locked, staked, and team allocations. The ratio of circulating to max supply indicates future dilution, so a token with 20% circulating and 100% max supply will see 5x potential sell pressure as remaining supply unlocks.

A treemap is a data visualization that represents hierarchical data as nested rectangles, where each rectangle's area is proportional to a numerical value. In crypto market heatmaps, each token is a rectangle sized by market cap and colored by performance, with rectangles grouped by sector. A treemap shows market-wide patterns in one view: which sectors dominate capital, which tokens are biggest, and which are moving hardest. Treemaps are preferred over pie charts when comparing hundreds of items simultaneously because rectangles pack more efficiently than slices.

Use a heatmap when you want to read the whole market at once: sector rotation, breadth, relative strength, extreme movers. Use a sortable table when you need to rank, filter, or export a specific list of tokens by a specific metric. They pair well: scan the heatmap to see where capital is flowing, then switch to a sortable view to drill into the tokens or sectors that stood out. Sharpe's Market Heatmap and Market Cap rankings cover both.

Basic market heatmaps are fine for casual reference but thin on sector analysis and programmatic access. Sharpe's heatmap adds narrative and ecosystem tiles built from every eligible member, coloring by funding, OI value change, RSI and relative volume as well as price, coin exclusions, and a free API and MCP server that serve the same numbers.
