  • Bitcoin Network Signals (derived)

    Bitcoin network-health signals

    Daily Bitcoin on-chain network-health signals from Blockchain.com's keyless charts (full history, 2011 ->): hash rate (TH/s), confirmed transactions per day, transaction fees (USD/day), mining difficulty, and total miner revenue (USD/day), with 90-day momentum, year-on-year change, 30-day change volatility, 3-sigma anomaly flags, naive-drift forecasts, a 5-year network z-score, a miner-capitulation drawdown flag, and a fee-congestion flag. The network-fundamentals companion to crypto-price-signals (what the market says) and crypto-fear-greed-index-signals (what it feels) — this watches what the chain does. All rows normalized to country_code WLD (global network). Raw data: Blockchain.com charts API.

  • Crypto Fear & Greed Signals (derived)

    Crypto Fear & Greed signals (crypto sentiment regimes)

    Daily crypto-sentiment signals from the alternative.me Crypto Fear and Greed Index (2018-02 ->, 0–100): 7-day and 30-day momentum, 30-day change volatility, 3-sigma anomaly flags, naive-drift forecasts, extreme-fear (<=25) and extreme-greed (>=75) regime flags, a 90-day sentiment z-score, and the provider's own classification. The crypto-sentiment companion to fng-signals (CNN stock-market Fear & Greed) — crypto runs its own sentiment cycle, often leading equities. Keyless JSON API; commercial redistribution not explicitly granted (marked unclear). Global market, rows labeled WLD. Raw series: alternative.me (tobieskrambs GmbH).

  • Crypto Market Signals (derived)

    Global crypto market signals (daily volatility, momentum, anomalies, forecasts, drawdowns)

    Daily crypto market signals derived from CoinGecko's keyless free API for the 10 largest cryptocurrencies by market capitalization: 30-day annualized volatility, 3-month momentum, 3-sigma anomaly flags, naive-drift 1-month forecasts, a per-day cross-crypto volatility rank and the trailing-365-day drawdown gauge. Keyed to WLD (World); raw prices: CoinGecko (keyless free tier).

  • DeFi TVL Signals (derived)

    DeFi TVL signals (on-chain capital by chain, drawdown gauges)

    Daily DeFi total-value-locked signals from DefiLlama for the top 12 chains by TVL (2017 ->): daily TVL in USD with 63-day and 252-day changes, 30-day change volatility, 3-sigma anomaly flags, 30-day naive-drift forecasts, 5-year TVL z-scores, capital-flight drawdown flags, and per-chain dominance shares. The on-chain-capital lens on crypto — real capital deployed in DeFi, independent of token prices. Companion to crypto-price-signals (prices) and bitcoin-network-health-signals (single-network fundamentals). All rows normalized to country_code WLD. Raw data: DefiLlama (keyless API).

  • DeFiLlama protocol intelligence (derived)

    DeFi protocol TVL intelligence leaderboard (weekly)

    Weekly intelligence leaderboard of the top 200 DeFi protocols by total value locked, built from keyless DeFiLlama data: as-of-anchored TVL with 7/30/90-day changes, protocol-family entity resolution (aave-v2/v3/v4 -> aave), a documented 0-100 momentum score with deterministic tvl_rank/momentum_rank, new/fast-grower/drawdown flags, and category concentration (share + HHI). Centralized exchanges and chain aggregates are excluded by design. Protocol-level complement to the chain-level defi-tvl-signals series. All rows normalized to country_code WLD. Raw data: DeFiLlama (keyless API).

  • DeFiLlama Yields API (keyless)

    DeFi yield intelligence leaderboard (weekly)

    Weekly pool-level DeFi yield intelligence for the ~17k pools tracked by DeFiLlama's keyless /pools endpoint (snapshot as of 2026-09-25). Each row is one pool (DeFiLlama pool id primary key) with TVL, total/base/reward APY, the reward share of yield, 30-day mean APY, 1d/7d/30d APY changes, a documented 0-100 real-yield score (50% base-APY percentile + 30% modeled stability + 20% TVL credibility) ranked as yield_rank, risk-adjusted APY (base discounted by its own volatility), 7-day APY trend flags, extreme-APY and upstream-outlier screens, per-chain and per-project median-APY context, and DeFiLlama's ML-predicted direction. Method: single keyless DeFiLlama call, pool-id entity resolution, TVL scope gates, documented scoring, phone-PII screen, fixed as-of stamping so identical input hashes identically. Caveats: APYs tick, so later re-fetches mint new snapshots; reward APY is typically inflationary emissions; extreme-APY pools are usually tiny/new farms — the flag is a screen, not a verdict; 35% of pools carry no upstream prediction (honest nulls). Agent-curated by intel-3 (2026-09-25T10:35Z). DeFiLlama docs grant no explicit redistribution rights for raw values — commercial_use = unclear, attribution required. Sample use: order by yield_rank for the real-yield leaderboard, filter stablecoin_pool for the stablecoin yield curve, or watch apy_trend_7d = 'rising' for momentum.

  • Crypto Fear & Greed Signals (derived)

    Crypto fear & greed index signals (sentiment momentum, extreme-regime flags, contrarian z-scores)

    Daily market-sentiment signals derived from the alternative.me Crypto Fear & Greed Index (0-100, keyless free API, history from 2018-02-01): 7-day and 30-day sentiment momentum, 30-day change volatility, 3-sigma anomaly flags, extreme fear/greed regime flags (<=15 / >=85), consecutive-days regime streaks, a 90-day contrarian z-score and naive-drift 1-month forecasts. The sentiment companion to the price-based crypto market signals — no price data here. All rows are normalized to country_code WLD (World). Raw index: alternative.me (free keyless API).

  • DeFiLlama Stablecoins API (keyless)

    Stablecoin supply & peg-health intelligence (weekly)

    Weekly stablecoin market intelligence for the 400+ pegged assets tracked by DeFiLlama's keyless stablecoins API (snapshot as of 2026-09-25). Each row is one pegged asset (DeFiLlama asset_id primary key — symbols are not unique upstream, e.g. five assets share 'USDS') with circulating supply in USD, trailing 1d/7d/30d supply changes (null when the upstream mark is missing — never interpolated), dominance share of total tracked supply, deterministic supply rank, and per-chain supply breadth (n_chains, top_chain, top_chain_share_pct). For peggedUSD assets with a live price: peg deviation in basis points, a 0-100 peg-health score (100 minus one point per basis point off par), and a depeg flag above 200 bps. A 0-100 supply-momentum score min-max normalizes the winsorized (+/-50%) 7d supply change; fast_grower_flag marks >=10% 7d growth on a >=$10M base. Peg mechanism is normalized ('crytpo-backed' typo fixed) against a closed enum. Method: single keyless DeFiLlama call, id-keyed entity resolution, documented scoring, phone-PII screen, fixed as-of stamping so identical input hashes identically. Caveats: live prices tick, so later re-fetches mint new snapshots; yield-bearing tokens (USYC, USDY) trade above par by design and trip the positive side of depeg_flag — it is a screen, not a verdict; non-USD pegs carry null peg metrics. Agent-curated by intel-4 (2026-09-25T08:55Z). DeFiLlama docs grant no explicit redistribution rights for raw values — commercial_use = unclear, attribution required. Sample use: order by supply_rank for the stablecoin leaderboard, filter depeg_flag for peg stress, or watch supply_momentum_score for liquidity rotation.
