Assuming you’re using Geth:
1. Connect to your geth node.
If you’re using a local node, you can use the IPC endpoint. For example:.
geth attach ipc:/home/ethereum/.ethereum/geth.ipc
If you’re using an infura node, you’ll need to use the RPC endpoint. For example:
geth attach https://mainnet.infura.io/v3/YOUR-PROJECT-ID
2. Use the eth_getTransactionByHash RPC call to get information about a particular transaction. For example:
> eth_getTransactionByHash “0x88df016429689c079f3b2f6ad39fa2c258a2529ef7e6dc77054e7bf099667ee”

blockNumber: “0x388372”,
from: “0x4e83362442a28205cecd5a72ee861a1f1b78070a”, // This is the sender’s address
gas: “0x15f90”, // This is the amount of gas used by the transaction
gasPrice: “0x4a817c800”, // This is the gas price in wei (10^-9 ETH)
hash: “0x88df016429689c079f3b2f6ad39fa2c258a2529ef7e6dc77054e7bf099667ee”, // This is the transaction hash
input: “0xa9059cbb0000000000000000000000004e83362442a28205cecd5a72ee861a1f1b78070a0000000000000000000000000000000000000000000000000000000000002710″, // This is the data field of the transaction, which in this case is a contract call (encoded as ABI) to the ERC20 transfer function transferring 2,712 tokens from sender to recipient with address 0x4E83362442A28205CECd5A72EE861A1F1B78070A. Note that this data field can also be empty for simple value transfers between addresses. To decode this data field, you can use an ABI decoder such as https://abi.hashex.org/ or https://toolkit.chainstack.com/decode-transaction-data, or if you’re using Geth you can use the admin_eth_abiDecodeLog RPC call (see https://github.com/ethereum/go-ethereum/wiki/Management-APIs#admin_eth_abidecodelog).
nonce”: “0x11″, // This is the nonce of the sending account, used to prevent replay attacks (https://en.wikipedia.org/wiki/Replay_attack). To get this value, you can use the eth_getTransactionCount RPC call (https://github.com/ethereum/wiki/wiki/JSON-RPC#eth_gettransactioncount). r”: “0xb59d55bfa4ef75554cd08ae867107dd0507ca55ddea349fb529462ba1607fe66”, // This is one of two values used to verify that the transaction was signed by the sender’s private key corresponding to their address (the other value being v). To verify that a transaction was signed by a particular address, you can use https://etherscan.io/, which will show you the signer’s address next to the “From” field if it was able to verify the signature, or you can use a tool such as https://github.com/kvhnuke/etherwallet/tree/mercury#online-signer to verify signatures yourself s”: “0x36b93de5502144b13ffda50cb968785fd3379783067c3196836aa49254355ea3″, // see r description above v”: “0x25″, // see r description above value”: “0xde08884c0751f24bebd58bb46089ec881810218e160b6f927ec8ede5460a6552” // This is the value being transferred in wei from sender to recipient }.
NOTE: WARNING: Before attempting to check your gas fee Ethereum, it is important to be aware of the risks associated with doing so. Gas fees can be high and volatile, and you may end up losing money if you do not correctly estimate the amount of gas required for a transaction. Be sure to research and understand the current gas fee costs before attempting to check your gas fee Ethereum.
As you can see from this example transaction, there are several fields which are important in understanding how much gas was used by a transaction:
gas – This is the amount of gas used by this transaction. Note that this is not necessarily equal to the amount of gas consumed by all of the computations performed by this transaction, since unused gas is refunded to the sender at the end of execution; rather, it’s equal to gas consumed – refunded gas .
In this example, we can see that 21000 – 24406 = 1594gas was consumed by this transaction (although note that refunds are capped at half of total gas used).
gasPrice – This is the price of each unit of gas used in wei . In this example, we can see that each unit of gas costs 4000000000 wei , or 0 .
04 ETH .
value – This is the value being transferred in wei from sender to recipient . In this case, we can see that 1 ETH is being sent from 0 x4E8 3362442A28 205CEC d5A72EE86 1A 1F 1B78070A to 0 xde08884 c075 1 F24BEBD58 BB46089EC 881810218E 160 B6F927EC 8EDE5460 A6552 .
To calculate the total cost of a transaction in ETH , simply multiply gasUsed * gasPrice . In our example above, this would be 1594 * 0 .
04 = 0 . 06376 ETH .
Alternatively, if you’re using Parity , you can use their traceTransaction API call instead (see https://wiki.parity.

When it comes to Ethereum, gas is everything. It’s what allows the decentralized network to function and keeps things running smoothly. So, what exactly is gas and how do you calculate it?
When a user wants to send ETH or tokens, they must include a gas fee to cover the cost of the transaction. The gas fee is calculated based on the amount of data included in the transaction, and the gas price, which is set by the user. The gas price is usually denominated in Gwei, which is worth 0.000000001 ETH.
When it comes to gas fees, Ethereum is no different than other blockchain platforms. Like Bitcoin, Ethereum has a block size limit that creates a fee market. And like Bitcoin, Ethereum’s gas fees have been on the rise in recent months as usage has increased.
A gas fee is a charge levied by Ethereum in order to cover the cost of running a transaction or contract on the Ethereum network. The gas fee is paid in ETH. Ethereum transactions are executed by “gas”, which is effectively a measure of how much processing power is required to run the transaction or contract.
Ethereum’s gas prices are based on the computational power needed to execute a transaction or contract on the Ethereum network. The higher the gas price, the more “fuel” is needed to complete the transaction, and the faster it will be processed. The gas price is not constant; it depends on the current demand for processing transactions on the Ethereum network.
To put it simply, Ethereum gas is a unit used to measure the amount of computational effort that it will take to execute a given transaction or smart contract. In other words, it represents the amount of work that needs to be done in order for a transaction to be processed by the Ethereum network. The gas limit is the maximum amount of gas that a transaction can use, and the gas price is the amount of ETH that a user is willing to pay per unit of gas.
Since the Ethereum blockchain is decentralized, there is no one “in charge” of it. This means that there is no customer service to contact if you have a problem. It also means that there is no one to set gas prices or to determine how much gas should be used for a particular transaction.
Gas fees on Ethereum are the fees that are charged by the network in order to process a transaction. The gas fees are used to pay for the computational resources that are required to execute a transaction. The fees are also used to pay for the storage of data on the Ethereum network.
Gas fees are the fees charged by Ethereum miners for processing transactions on the Ethereum network. These fees are paid in ether, the native currency of Ethereum. The gas fee is calculated based on the amount of gas used by a transaction, and the gas price, which is set by the miners.
When it comes to blockchain technology, one of the most frequently asked questions is: “What is gas fee for Ethereum?”
In order to understand what gas fee is, we must first understand what Ethereum is. Ethereum is a decentralized platform that runs smart contracts. These contracts are apps that run exactly as programmed without any possibility of fraud or third-party interference.
