Direct Ethereum event-log evidence of large USDT/USDC transfers, mints and redemptions above a whale-scale threshold, scanned block by block rather than sampled from periodic total-suppl… Purpose: Give an autonomous buyer direct transaction-level evidence of large stablecoin transfers, mints and redemptions as blocks close, complementing the periodic total-supply pulses in the stablecoin-intelligence family. 5-minute freshness target; missing evidence is reported explicitly rather than invented.

Directional Bitcoin/stablecoin-liquidity transmission context from validated 24-hour stablecoin supply change and BTC spot momentum, with regression beta explicitly withheld until calibrated. Purpose: Test whether stablecoin supply impulse and Bitcoin price momentum are currently aligned while refusing to publish an uncalibrated causal beta coefficient. 5-minute freshness target; missing evidence is reported explicitly rather than invented.

Direct CFTC weekly change in leveraged-fund long, short and spread positions for CME Solana, including change in net exposure. Purpose: Detect whether reported leveraged-fund exposure in CME Solana shifted toward net-long, net-short or stable positioning during the latest CFTC week. 168-hour freshness target; missing evidence is reported explicitly rather than invented.

Solana validator count, delinquency, stake concentration (Gini, Herfindahl, top-10 and top-33 share), the superminority able to halt consensus and commission distribution, read from getVoteAccounts on Solana's own public JSON-RPC. Purpose: Measure how concentrated Solana consensus stake currently is and how many validators are delinquent without inferring operator identity or geography. 15-minute freshness target; missing evidence is reported explicitly rather than invented.

Live perpetual-futures funding rates for BTC, ETH, SOL and XRP. Purpose: Give market-neutral and basis-trade agents a fresh, multi-venue funding-rate reading without polling several exchanges and reconciling several schemas. 5-minute freshness target; missing evidence is reported explicitly rather than invented.
