ethereum: web3.py basis price

As a developer working with Ethereum and his blockchain network, you encountered a common problem that can arise, comparing gas prices via the Web3 library compared to those obtained from the Etherscan transaction. In this article we will enter it, which can lead to this discrepancy and study potential solutions.

What’s going on?

By using the Web3 library to get Python “Gaseprice” of the property of the property, you basically ask for the price of gas related to this transaction. However, comparing this value with what comes from the Etherscan transactions, there may be slight differences for various reasons.

Possible reasons:

1
Transaction time tags : Gas prices are usually calculated at the time of execution (e.g. blocking time stamps), and then periodically updating the network. These updates can lead to a delay that causes slight inconsistencies between secured Web3 values ​​and results from Etherscan.

• Network overload : If a large number of transactions are made at the same time, this may cause gas prices at different times, causing potential inconsistencies compared to Etherscan values.

3
gas prices : The Ethereum network constantly updates gas prices using `This process does not always reflect the latest gas prices in real time, which may cause slight discrepancy between the web3 values ​​and the results from Etherscan.

• Make sure that both methods use the same version of the protocol, network configuration and other appropriate settings.

solutions:

1
Use a newer service provider : If possible, switch to a newer Web3 library or a service provider that can provide the latest price data.

• Make sure that all block number updates are reflected in the "Gaseprice" value.

Python

No web3 import web3

Provider = web3 (web3.httpprovider ('

Disable gas price updates

Provider.forcegasprice = True

4
Use the Etherscan Library

: Consider the use of libraries such as `or ‘Python-ethereum’, which are specially designed to interact with the Ethereum network and can provide more accurate results.

5
Check gas price updates in the console : Start a test transaction in the local network to determine whether gas prices are immediately updated in both Etherscan and Web3.

Application

Although time can be a contributing factor, it is important to consider other potential problems when comparing gas prices between the values ​​provided by Web3 and the results from the Etherscan transaction. By studying solutions, such as the latest use of service providers or introducing gas prices manually (if necessary), you can reduce the likelihood of incompatibilities and ensure accurate work results in the development of Ethereum.

code:

Here is an example of testing gas prices for Python:

“ Python

No web3 import web3

Provider = web3 (web3.httpprovider (‘

Get the current block number and time stamp

Blocknumber = provider.currentblocknumber

Time marker = Supplier. Typemp ()

Recover the gas price with the latest service provider (optional)

to try:

Gasprice = service provider.
