Is there any way to get a raw transaction via JSON RPC? I know how to get tx_hash from txpool, next I can get data like "from", "to", "gas", "input"... But how to get raw hex string?

I mean a raw tx like this:

0xf8ab82127c8506fc23ac0082926994b2a736980815d9c3a960e1c2a88042e4a9c9397880b844a9059cbb00000000000000000000000098aa1ad237106608b44e3a2fad6755fd5d486d3800000000000000000000000000000000000000000000000000000004a484410025a024bd7fe9b26f465ea5a06c5feb90894c60e7a5eb06a8d4bed6a729789be41660a02a9c4c909a3ab60ae76983706f1b72044572d5b9a28445771365d95ad03d1723

AFAIK there's no geth api to obtain the raw transaction. However you can get all tx fields with eth_getTransactionByHash and construct the raw transaction with them.

  • How can I construct raw_tx with fields from eth_getTransactionByHash? As I understand, I need to have private_key to do it. Is it possible to create raw_tx without private key?

  • @MaxBlock You can use ethereumjs-tx and construct a transaction passing the fields returned by getTransactionByHash (including the signature v, r, s). Then use .serialize() to obtain the raw transaction.
