I ran yarn upgrade --latest and I got the below. But I thought I just upgraded why the below is asking me to update again? If so, should I and how to?

This is caused because the latest version of @walletconnect/web3-provider package depends on packages of deprecated version. So even though you upgrade the packages listed in package.json, the package's dependencies are not upgraded, causing the warning. However, upgrading all of them is not recommended because dependency version mismatch can cause issues with the dependent package. The best way is to create PR at the dependency repo to upgrade deps.

QUESTION

Web3 SendSignedTransaction through Infura doesn't appear in the Etherscan transactions list

Asked 2021-Sep-02 at 22:29

OVERVIEW

Hello everyone, I am neither a developer nor a programmer, but I've started this Udacity Blockchain Nanodegree Program and I started programming some blockchain applications.

From the course I started to code a simple program to send some Ether from one Metamask account to another one, both accounts are in the same testnet (Rinkeby).

This is what I am using for program so far:

Metamask with the 2 accounts in the Rinkeby Testnet.
Web3 version 1.5.1
ethereumjs-tx version 2.1.2
Infura Rinkeby Endpoint

PROBLEM

The problem is that the course is outdated and most of their code doesn't work anymore. So, I started implementing my code after 3 days of searching through the Web3 website ( link: https://web3js.readthedocs.io/en/v1.4.0/index.html ), I managed to write the code that you can see in the snippet.

The code throws no errors on my end, and when I check the number of transactions (including the pending ones), the number of transactions keeps increasing each time I run my code. But, when I check the Rinkeby Etherscan website ( link: https://rinkeby.etherscan.io/ ), the transactions are nowhere to be found in the transaction list (completed, pending, failed, outgoing and incoming transactions).

QUESTIONS

What is/are the problem/s with my code? How can I solve it/them?
How do I calculate the GasPrice and how do I determine the GasLimit? I only want to make a transaction to send X amount of Ether with no data.
I tried to use the same GasPrice and GasLimit as Metamask, but it throw me the error "Intrinsic gas too low". Why does it happen? Because, I had no problems using those values with Metamask, and the transaction to send some ether from one of my metamask account to the other took less than 3 minutes to completed (I sent the transaction from the Metamask Plugin).
Does the chain's fork has anything to do with this problem? If so, How do I check the correct fork for my two accounts in Metamask?

NOTE

I am sharing through the code the private key for the senderAccount because these 2 accounts are only for testing this particular code in the Rinkeby Testnet. I am not planning to use them as wallets.

In order to use the .send({from: ...}) method, you need to

Have the from account unlocked on your provider.

OR
Add its private key to the web3 account wallet (docs)

Ulocked provider account

This approach is mostly used on local providers (e.g. Ganache) that fund and unlock some accounts by default.

Keeping an unlocked account on a production provider is unwise, because anyone who queries the provider can send transactions.

Web3 account wallet

You need to pass the private key that generates the from address.

Unfortunately, most of the Web3 stack relies heavily on window, browser and external, crypto dependencies which aren't available on server-side. This isn't just an issue with Gatsby, but other SSR and static site generators (e.g. Next.js) as well.

There are a few workarounds though. See Using Client-Side Only Packages on Gatsby

Use a different library or approach
Add client-side package via CDN
Load client-side dependent components with loadable-components
Use React.lazy and Suspense on client-side only

Depending on your requirements #1 is likely not an option. I've had better success using ethers, instead of web3. But you'll likely run into similar issues with other packages at some point.

A combination of #2 and 3/4 will be the way to go. First, remove the packages (web3) that are causing issues and load them either from gatsby-browser.js or using react-helmet on the page/component that's using it.
