ENTERPRISE-GRADE INFRASTRUCTURE
Why Choose Dedicated Archive Nodes
Shared or public RPC endpoints introduce performance bottlenecks and security risks. Our dedicated EVM archive nodes provide the predictable, high-performance foundation your application needs to scale.
01
Full Historical Data Access
Query any transaction, event, or state from any block in the chain's history. Essential for analytics dashboards, compliance reporting, and complex DeFi applications that require deep historical context.
