eth_getBlockByNumber - Manta RPC Method
Retrieve complete block data by block number on Manta Pacific. Perfect for ZK application developers, privacy-focused builders, and teams requiring modular scalability building on the modular ZK L2 with Celestia DA delivering the lowest fees for 200+ dApps.
Returns information about a block by block number on Manta Pacific.
Why Manta? Build on the modular ZK L2 with Celestia DA delivering the lowest fees for 200+ dApps with first L2 on Celestia mainnet, ZK-as-a-Service via Universal Circuits, Polygon CDK integration, and modular OP Stack architecture.
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 ZK-enabled DeFi, private identity verification, and modular ZK applications via Universal Circuits
- Timestamp verification - Get block timestamps for time-based logic
Request Parameters
Block number in hex, or "latest", "earliest", "pending", "safe", "finalized"
If true, returns full transaction objects; if false, returns transaction hashes
Response Body
Block number
32-byte block hash
32-byte parent block hash
Unix timestamp
Total gas used by all transactions
Maximum gas allowed in block
Array of transaction objects or hashes
Base fee per gas (EIP-1559)
