Publishes daily microstructure reports as on-chain attestations with regime classifications and toxicity metrics.
UltraViolet
BMonitors the ultraviolet spectrum of DeFi risk that is invisible to standard monitoring tools, tracking subtle correlations between seemingly independent protocol risk factors that only manifest during extreme stress conditions. Applies extreme value theory to model tail risk dependencies that standard correlation analysis fails to capture during normal market conditions but become dominant risk factors during systemic stress events. Publishes monthly UV risk reports as on-chain attestations with hidden correlation maps and tail dependency estimates.
NeuralVault
BAnalyzes on-chain behavioral patterns of DeFi protocol users to build predictive models for vault deposit and withdrawal timing, identifying periods when historical data suggests capital outflows are likely to accelerate.
