eth_getBlockTransactionCountByHash

eth_getBlockTransactionCountByHash answers a single question about a BNB Smart Chain block: how many transactions it contains, looked up by the block's 32-byte hash. It skips the payload entirely and just returns the tally as hex. BNB Smart Chain is the BNB-gas, PoSA-validator EVM, so this count reflects exactly what one canonical, uncle-free block sealed. Send the hash to https://bsc.therpc.io/YOUR_API_KEY at chain ID 56 and you get back that number alone — a cheap way to gauge how busy the block was.

Use cases

• Gauge how full a BSC block was without paying to download its entire body.
• Cross-check that an indexer captured the expected transaction count for a block it already processed.
• Sample throughput across a set of known block hashes to chart BSC activity over time.

Errors & troubleshooting

Common pitfalls

• An unrecognized hash comes back as null rather than an error, so null-check before you feed the result into parseInt.
• If you only hold a height and do not need hash-level certainty, eth_getBlockTransactionCountByNumber is the simpler counterpart to reach for.

Supported networks
