eth_getBlockByNumber - Boba Network RPC Method

Retrieve complete block data by block number on Boba Network. Perfect for AI dApp developers, enterprise integration teams, and builders requiring offchain compute access building on the Hybrid Compute L2 enabling smart contracts to access AI models and Web2 APIs natively.

Returns information about a block by block number on Boba Network.

Why Boba Network? Build on the Hybrid Compute L2 enabling smart contracts to access AI models and Web2 APIs natively with HybridCompute 2.0 for native AI/API access, $70M ecosystem funding, OP Stack compatibility, and two-way offchain integration.

Use Cases

The eth_getBlockByNumber method is essential for:

  • Block explorers - Display complete block information
  • Transaction indexers - Process all transactions in a block
  • Analytics platforms - Analyze blockchain data for AI-powered dApps, Web2 API integration, enterprise blockchain solutions, and offchain computation
  • Timestamp verification - Get block timestamps for time-based logic
