FAQPage Schema

How do I access multichain RPC endpoints for building web3 apps?▼

Access multichain RPC endpoints by appending a token-authenticated access token to a single URL. This provides plug-and-play connectivity to 100+ blockchains via JSON-RPC, WS, GraphQL, or REST interfaces for your web3 apps.

Can I use Ethers.js with a single blockchain RPC endpoint for multiple chains?▼

Yes, Ethers.js integrates directly with the single blockchain RPC endpoint. You can route requests across 100+ supported chains by configuring the token-authenticated URL within your Ethers.js provider setup.

What is the best way to test smart contracts across different blockchains?▼

The best way to test smart contracts across blockchains is using a unified RPC endpoint. It removes the need to manage multiple node providers by routing requests through one token-authenticated URL across 100+ chains.

Does GetBlock support real-time data streams for multichain dashboards?▼

Yes, GetBlock supports real-time data streams for multichain dashboards via WebSocket and Yellowstone Geyser integration. This enables live event tracking across 100+ blockchains through a single endpoint URL.

Do I need dedicated nodes for scalable blockchain workloads?▼

Dedicated nodes are optional for scalable blockchain workloads. The platform offers shared CU-based pricing for standard requests and dedicated nodes to handle higher-volume scalable workloads across 100+ supported chains.

Why manage multiple node providers when a single URL covers 100+ chains?▼

Managing multiple node providers is unnecessary because a single URL with token-based authentication covers 100+ chains. This unified access eliminates complex authentication schemes and simplifies node management across networks.
