nonce
; it is an important piece of information, especially to ensure that a transaction is not sent twice.
address
— the address to retrieve the transaction count.
quantity or tag
— the integer of a block encoded as hexadecimal or the string with:
latest
— the most recent block in the blockchain and the current state of the blockchain at the most recent block. A chain reorganization is to be expected.safe
— the block that received justification from the beacon chain. Although this block could be involved in a chain reorganization, it would necessitate either a coordinated attack by the majority of validators or an instance of severe propagation latency.finalized
— the block accepted as canonical by more than 2/3 of the validators. A chain reorganization is extremely unlikely, and it would require at least 1/3 of the staked ETH to be burned.earliest
— the earliest available or genesis blockpending
— the pending state and transactions block. The current state of transactions that have been broadcast to the network but have not yet been included in a block.quantity
— an integer value identifying the number of transactions sent from an address at the specified block.eth_getTransactionCount

is to create the transaction object built in a script designed to send a transaction. The nonce field is required, and it is retrieved using the eth_getTransactionCount
method.
The following code shows how to build a rawTransction
using web3.js.
nonce
for the sender’s address, which is done through the getTransactionsCount
function. This function calls web3.eth.getTransactionCount
, passing the sender’s address and returning the count of transactions previously sent from this address. This count, used as the nonce
, is critical for ensuring the transaction’s uniqueness and order in the blockchain.
After setting up the sender’s wallet with a private key, the script defines the transaction parameters, including the toAddress
and the value
(amount of ETH to be transferred). The value
is defined in Wei and then converted to ETH for logging purposes.
The script then constructs a transaction object that includes essential fields such as from
, to
, value
, and nonce
. While gasPrice
and gasLimit
can be specified; they are optional in this script, as Web3.js will provide default values if they are not explicitly set.
The transaction is sent using web3.eth.sendTransaction
, which handles the transaction signing under the hood with the private key from the wallet. This approach simplifies the transaction creation and sending process, as the complex steps of manually creating, signing, and serializing the transaction are abstracted away by Web3.js. This will ultimately send a transaction using the eth_sendRawTransaction method.
Once the transaction is sent, a receipt is obtained and logged, providing details of the executed transaction. In case of any errors during the transaction process, these are caught and logged, aiding in troubleshooting and ensuring robust error handling.
The sendEther
function encapsulates the entire process, and its execution triggers the sending of the transaction, demonstrating a streamlined and efficient way to handle Ethereum transactions programmatically.The address nonce
