Crypto Desk — Final Ruling: Additional Data Sources & Advanced Metrics

Panel: Opus, Sonnet, Grok 3, Gemini Pro 3.1 Judge: Opus (via synthesis) Date: 2026-03-25 Grade: A- (strong consensus on core signals, minor dissent on drops)

Consensus Points

1. Options-Implied Probability vs Kalshi Price (UNANIMOUS — Opus, Sonnet, Gemini)

The killer metric. Use Deribit IV + Black-Scholes d2 to calculate the options market's implied probability for "BTC above $K by date T". Compare to Kalshi price. The gap IS the edge. Zero new API calls.

2. Variance Risk Premium (UNANIMOUS — Opus, Sonnet, Gemini)

VRP = DVOL - Realized Vol. One new free Deribit endpoint. When VRP > 15, downside contracts are overpriced. When VRP < 0, crash in progress.

3. Drop NFT Blue Chip Floors (UNANIMOUS — all 4)

Zero predictive value for BTC/ETH binary contracts since 2022.

4. Polymarket CLOB API (STRONG — Opus, Sonnet)

Fill the stub. Direct Kalshi vs Polymarket arbitrage intelligence. Free, no auth.

5. Funding Rate Z-Score (STRONG — Opus, Sonnet)

Normalize funding historically, volume-weight across exchanges. |z| > 2 = mean reversion within 48h. Zero new API calls.

6. Mempool Fee Velocity (STRONG — Opus, Sonnet, Grok variant)

Fee spikes from whales panic-moving BTC to exchanges. 15-60 min lead time. Nobody in prediction markets watches this.

7. Deribit Block Trades (STRONG — Opus, Sonnet)

Institutional options flow. Filter for block_trade_id. Cluster of OTM puts = smart money hedging.

Dissent Rulings

Fear & Greed Index — KEEP (Gemini says drop, 3 say keep)

Gemini argues it's a lagging derivative of inputs we already collect. Valid point, but it's one API call and feeds the Master Sentiment composite. Keep at reduced frequency (1x daily).

GitHub Dev Activity — KEEP BUT REFOCUS (Gemini says replace, others silent)

Replace dead repos (Acala, MakerDAO) with infrastructure repos: foundry-rs/foundry, paradigmxyz/reth, matter-labs/zksync-era, anza-xyz/agave. Add emergency commit detection on bitcoin/bitcoin.

Exchange Token Health — REDUCE (Sonnet says drop most)

Keep BNB only. Drop CRO, LEO, KCS, MX. The FTX canary thesis was 2022.

Build List

Phase 1: New Data Sources (2 new files)

File: src/pipeline/data/crypto/advanced-sources.ts — New free API endpoints:

1. Deribit Historical Volatility (realized vol for VRP)
2. OKX Top Trader Long/Short Ratio
3. OKX Taker Buy/Sell Volume
4. Deribit Block Trades (institutional flow)
5. SoSoValue BTC ETF Daily Flows (fills stub)
6. Polymarket CLOB prices + order book
7. Cross-chain Bridge Flows (DefiLlama bridges API)
8. Mempool Fee Velocity (enhanced mempool analysis)
9. Altcoin Aggregate OI (Binance futures, top 15 alts)
10. Coinbase Premium Index (Coinbase vs Binance BTC price)

File: src/pipeline/data/crypto/advanced-metrics.ts — Calculated from existing + new data:

1. Options-Implied Probability (Black-Scholes d2 → N(d2) for any strike/expiry)
2. Variance Risk Premium (DVOL - realized vol)
3. Funding Rate Z-Score (cross-exchange, volume-weighted, 30d lookback)
4. Funding-OI Divergence (4 regime patterns)
5. Liquidation Cascade Probability
6. Term Structure Skew Score (near vs far IV skew)
7. On-Chain Accumulation/Distribution Score (5-component)
8. Cross-Market Regime Classifier (4 regimes: Macro Slave, Crypto Native, Risk Off, Euphoria)

Phase 2: Cron Wiring

• Advanced sources: 4 cron entries at various frequencies
• Advanced metrics: 1 cron entry after composites (every 4h)

Phase 3: Drops/Reductions

• Remove NFT floor price collection entirely
• Remove CRO, LEO, KCS, MX from exchange token health (keep BNB only)
• Reduce trending coins to 1x daily
• Reduce Fear & Greed to 1x daily
• Replace dead GitHub repos with infrastructure repos

Implementation Notes

• All new sources are free, no API keys needed (except Glassnode free tier — optional)
• Self-initializing table pattern for any new tables
• getDb() from ../../db.js — better-sqlite3, SYNC, no await on DB calls
• safeFetch() pattern with timeout and User-Agent header
• pino logger per module
• ESM with .js extensions on all imports
