This would result in the following gas sum 21000 + 3 + 3 + 5000 (tx_gas + push_gas + push_gas + sstore_clear_gas). The total amount of which may be refunded is therefor gas_sum / 2 (13.003). The amount refunded is 15.000 but since this clearly exceeds the maximum of …

Instead, gas exists only inside of the Ethereum virtual machine as a count of how much work is being performed. When it comes to actually paying for the gas, the transaction fee is charged as a certain number of ether, the built-in token on the Ethereum network and the token with which miners are rewarded for producing blocks.

Feb 26, 2018 · Gas price seems to be around 3 GWei, not the 50 GWei given in the answer. I got the information from EthGasStation, which gives most of the information I needed. According to their calculator (and my calculations), 1 kB needs 625000 gas and with current gas and ether prices, 1 kB = $1.57875 (0.001875 ETH)

A spreadsheet of opcodes and their gas costs that Ethereum launched with are here. It has some analysis per How were gas costs chosen for the Ethereum Virtual Machine instructions? The spreadsheet is titled 1.0 gas costs, so it might not be updated. edit 2017-12-11: here is the EIP-150 revision of the spreadsheet. Here is a small snippet from it:

May 18, 2023 · In the middle ground, you can search online for Ethereum gas estimators and gas prices, and set your MaxFeePerGas (and MaxPriorityFeePerGas) to the value they suggest at that time. Note: the gas limit can also affect the priority of your transaction:

May 29, 2017 · Max gas limit for a transaction is the gas limit for that particular block. you can get the gas limit of block by eth.getBlock('latest') and checking gasLimit parameter in it. gas limit of the next block is 1.2 times of the moving avg of gas limit of all previous blocks.

View will not cost gas only if called from outside the network, that is if a function in a contract is view and is called from another contract it will cost gas. The reason it will not cost gas if called from outside the network is that the function can be resolved in the local node that you are using to connect to the network without ...

Feb 25, 2022 · Ether transfer to an externally-owned account will cost you exactly 21,000 gas units. Ether transfer to a smart contract will cost you more than 21,000 gas units, and the exact amount depends on the implementation of the fallback function in that contract.

Pure and View functions don't cost any gas to call if they're called externally from outside. In this type of case, there won't be any transaction initiated because this will be like just querying the blockchain for its current state and nothing will be changed. But they do cost gas if called internally by another function.

Jul 14, 2018 · The gas limit should be as high as your transaction will consume, and no higher. The amount of gas a transaction consumes depends on what it does. (Bear in mind that if your transaction results in gas refunds, for example because it deletes storage data, you still need to account for it in the gas you supply.)
