Everything you need to build reliable, intelligent blockchain infrastructure

Adaptive Routing

Smart penalty-based routing that automatically shifts traffic away from slow or failing providers. Four global regions ensure localized failover - if a provider fails in South America, we route around it without affecting other regions.

  • Penalty-based traffic shifting prevents degradation
  • Four independent regions: EU, US, SA, SEA
  • Per-region provider health isolation
