Polygon method guide

Last updated:

eth_getBlockTransactionCountByNumber returns how many transactions are contained in a given Polygon block, selected by block number (a 0x-prefixed hex integer) or by one of the named block tags. The count is returned as a 0x-prefixed hexadecimal string.

Use it when you only need the transaction count and not the full block body — for example to size pagination, to detect empty blocks, or to decide whether a heavier eth_getBlockByNumber call is worth issuing. If you already have a block hash instead of a number, use the sibling method eth_getBlockTransactionCountByHash.

This is a light read on the free tier (polygon_read_rpc category). Polygon blocks are produced about every ~2.1 seconds and typically carry ~50–150 transactions, so latest advances quickly — poll on roughly that cadence if you are tracking the chain tip. A request for a block that does not exist (e.g. a height beyond the current chain head) returns a result of null rather than an error.
