starknet_getBlockTransactionCount - Get Block Transaction Count
Get the number of transactions in a Starknet block by block ID. Useful for block analysis, throughput monitoring, and indexing pipelines.
Starknet RPC endpoint: endpoint URLs, plans and pricing.
Returns the number of transactions in a specific Starknet block. The block can be identified by hash, number, or the "latest" / "pending" tags.
Overview
This method provides a lightweight way to query block activity without fetching full block data. It is commonly used in monitoring dashboards, indexing pipelines, and throughput analysis tools. Starknet processes batches of transactions into blocks that are then proven and submitted to Ethereum L1, so transaction count per block is a useful metric for understanding network load.
Starknet blocks can contain various transaction types including INVOKE, DECLARE, DEPLOY_ACCOUNT, and L1_HANDLER transactions. This method counts all transaction types in the block.
