everyone is optimistic about the rise and fall of the cryptos. personally, you can all agree with me that the bitcoin price is going to exceed its current value to $71,415 in February 2022, panelists have also predicted the bitcoin price to skyrocket to an average of $249,578 by the year 2024 which could also influence the price of altcoins. it's never too late to buy and hold of Ethereum/Bitcoin now is the right time. I personally have sustained over $567,000 since last year still now copying advance trade signals and indicating stop lost and manage risk following a mentorship and a blockchain specialist https://declanbrock.com/ his pattern are very lucrative with full of complex.

Hello everyone. Can I get help for AWS Lambda and Web3?

When I try to run the main.zip file in the AWS lambda, I get an error about cytoolz module. The library is installed properly and working fine if I run the file through the shell. I tried installing the web3 module again, as well as the cytoolz module separately, but no luck.
{
"errorMessage": "Unable to import module 'lambda_function': No module named 'cytoolz.itertoolz'",
"errorType": "Runtime.ImportModuleError",
"stackTrace": []
}
However, when the file is hosted in the cloud9, which is an Amazon Web Services (AWS) service, runs perfectly.

Hey guys, I wanted to understand how does one fetch all the past event logs for a contract using the RPC endpoints?
If I make a filter then it only filters the events starting from the current block so there is no way to get past events except the explorer APIs

hello, everyone :D sorry if this is not the right place to ask. We're having trouble with some tuple data-types using 5.26.0. Specifically I can't call functions with the type tuple[] because the ABI isn't recognised. I see the latest master branch has a commit related to tuples. Will that help my case? And if so, when is a new pypi release planned?

Thank you!

Just as a reminder, which we try to do periodically, the Discord is a better place to get quicker answers as it is more frequently monitored: https://discord.gg/GHryRvPB84
@calina-c the recent changes to master do seem to be related to what you are experiencing

Hi
does anyone know how to fetch the mint price of a collection
My approach was to fetch all Transfer events and then see if it was from a null address etc

Hello Community!

I'm a blockchain, .NET and Android app developer and have been programming for over 15 years.

My vision was to develop a program that is easy to use and still offers many functions.

The "Blockchainius" project arose from this thought.

Blockchainius is a program for automatically creating private keys and wallets in all available networks that support 0x addresses like Ethereum.

With Blockchainius, the automatically created wallets can be automatically checked for credit. This credit can also be automatically sent to your wallet if you wish.

8 networks are preconfigured in the default settings: ETH, BSC(BNB), Matic, AVAX, FTM, Telos, Arbitrum, Optimism

Additional networks can be easily added with ChainID, RPC URL, symbol, coin name.

The tool is available as a freeware version (15% developer fee automatically when a wallet is found) or as a paid version (lifetime license) without fees.

If desired, an automatic e-mail notification with the most important information can also be sent.

Blockchainius is available today with update 1.3.5.0.

Windows 7 - 11 and the current .NET Framework are required.

The software can also be operated in virtual machines (VMWare, VirtualBox and others).

I am available for further questions.

The software is available here: https://www.blockchainius.net

Hi. I work with my private PoA network and setup it with {"baseFeePerGas": null}.
I added construct_sign_and_send_raw_middleware to my python bot. And I got an error

.../web3/_utils/transactions.py", line 64, in <lambda>
web3.eth.max_priority_fee + (2 * web3.eth.get_block('latest')['baseFeePerGas'])
KeyError: 'baseFeePerGas'

What I can do with it? It tries to get baseFeePerGas but my node returns null

1 reply
Eth-Gitter-Bridge
@Eth-Gitter-Bridge

<Felipe Selmo (fselmo)> This error is happening because no fee value is set for transactions and thus web3.py is trying to use some information to set a default value for you. Since the library is built around Ethereum, it will look for baseFeePerGas to attempt to estimate a good fee for the transaction. If you set your own fee values, you can likely get around this error. This is usually done as a gasPrice on other chains but can also be done via a combination of maxFeePerGas and maxPriorityFeePerGas values on Ethereum.

Hope that helps.

hello, I'm trying to port some code from js to python and having some issues. the js code generates uniswap swap commands using populateTransaction, then sends the tx data to a smart contract that actually executes. when I get transaction bytes generated by populateTransaction in JS, things work fine. in python, I dug down and used prepare_transaction to generate transaction data, but this causes the contract to error. any ideas what I might look at to debug this? or if there's a better way to replicate populateTransaction in web3py?

I should add, I'm not using build_transaction because that causes a revert (contract calls are valid from the executing smart contract, so they revert if I try to set them up locally)
