Fetch a block

After you know the tip, fetch a concrete block. Pass false (or equivalent) when you only need headers — full transaction objects cost more bandwidth and credits.

eth_getBlockByNumbergetBlockgetblock

← All guides

Steps

  1. Get a block identifier: height (hex on EVM), slot (Solana), or hash (Bitcoin).
  2. Call the family get-block method with the right verbosity flag.
  3. Remember: full node, not archive — very old historical blocks may be pruned depending on the chain and node config.
  4. For transaction details inside the block, follow the get-transaction guide.

Tips

  • On EVM, true as the second arg expands full transactions — heavy; prefer false then eth_getTransactionByHash.
  • Solana getBlock requires a slot that still exists in the node’s retention window.
  • Bitcoin verbosity: 0 = hex, 1 = JSON txids, 2 = JSON full txs.
