Broadcast transaction

Submit a signed raw transaction (hex) to the network via Blockchair's push/transaction.

How to use

  1. Sign your transaction offline using your wallet or a library (bitcoinjs-lib, ethers, etc.). This page does NOT sign — it only relays.
  2. Pick the chain that matches your signed transaction. Sending a BTC tx on the LTC network (or vice versa) will fail.
  3. Paste the raw transaction hex into the textarea (e.g. 0100000001… for Bitcoin-family, or 0xf86c… for Ethereum).
  4. Click Broadcast. On success the response shows the accepted txid; on failure you'll see the node's rejection reason (already-spent inputs, low fee, malformed hex, etc.).
  5. Tip: always double-check the hex — broadcasted transactions cannot be undone.
