How to query local Ethereum blockchain for a specified transaction?

Question

I want to find specified transaction. How can I query my local Ethereum blockchain from the console?

Answer 1

Find Transaction By Transaction Hash

Ideally you would have saved the transaction hash, and then you can query for the transaction using this transaction hash. Here is an example:

> eth.sendTransaction({from: eth.accounts[0], to: eth.accounts[1], value: web3.toWei(1.23456, "ether")})
"0x4a950bc3651c991aa2ff50fc49601e69960f1f75823df3d4a5dfc7d3c5e3c190"

Use eth.getTransaction(txHash) to get the transaction details. The transaction has not been mined into a block yet:

> eth.getTransaction("0x4a950bc3651c991aa2ff50fc49601e69960f1f75823df3d4a5dfc7d3c5e3c190")
{
  blockHash: null,
  blockNumber: null,
  from: "0xa485ab3ad17cd9aca6fd5343a53a513685c7e0ed",
  gas: 90000,
  gasPrice: 20000000000,
  hash: "0x4a950bc3651c991aa2ff50fc49601e69960f1f75823df3d4a5dfc7d3c5e3c190",
  input: "0x",
  nonce: 201,
  to: "0xcf358622d70f62f212aef64e7e26e4746dc84eb3",
  transactionIndex: null,
  value: 1234560000000000000
}

The transaction has just been mined:

I0430 21:20:39.493822   14719 worker.go:569] commit new work on block 10543 with 1 txs & 0 uncles. Took 1.257998ms

> eth.getTransaction("0x4a950bc3651c991aa2ff50fc49601e69960f1f75823df3d4a5dfc7d3c5e3c190")
{
  blockHash: "0xeb71b38f6301c570a46d864a0159ddd2b352dec8409a64f210778d8826e4fda0",
  blockNumber: 10543,
  from: "0xa485ab3ad17cd9aca6fd5343a53a513685c7e0ed",
  gas: 90000,
  gasPrice: 20000000000,
  hash: "0x4a950bc3651c991aa2ff50fc49601e69960f1f75823df3d4a5dfc7d3c5e3c190",
  input: "0x",
  nonce: 201,
  to: "0xcf358622d70f62f212aef64e7e26e4746dc84eb3",
  transactionIndex: 0,
  value: 1234560000000000000
}

Find Transaction Using A Script To Search For Transaction To/From Account

Otherwise see the answer Script To Find Transactions To/From An Account to the question Common useful JavaScript snippets for geth for a scripts to search the blockchain for your transaction.

Answer 2

to get details of any transaction you need a transaction hash

var tx = {from: eth.coinbase, to:eth.accounts[1], value: web3.toWei(10, "ether")}
> personal.sendTransaction(tx,"your_passphrase")

after executing this you will get the transaction hash

"0x575021e07c382ff4af7deaa884bc1e32c21a1e1a537530495460fb5f6bb295a6"

Using this transaction hash you will get the transaction transaction details can be of three types

1. Transaction Receipt

2. Transaction

3. Block

1.To get transaction Receipt

> eth.getTransactionReceipt("0x575021e07c382ff4af7deaa884bc1e32c21a1e1a537530495460fb5f6bb295a6");
{

  transactionIndex: 0
}

2. To get Transaction

eth.getTransaction("0x575021e07c382ff4af7deaa884bc1e32c21a1e1a537530495460fb5f6bb295a6")

  transactionIndex: 0,
  v: "0x1344248",
  value: 10000000000000000000
}

3. To get the Block which contains this transaction you need to use block number which will be found in above two details of transaction

eth.getBlock(17003)

}

you can use all 3 of them from javascript by using web3

1. web3.eth.getTransactionReceipt("transaction Hash")
2. Web3.eth.getTransaction(transaction Hash)
3. web3,eth.getBlock(Block number/block hash)
