Getting Started

Requirements

git
- You'll know you did it right if you can run git --version and you see a response like git version x.x.x
Nodejs
- You'll know you've installed nodejs right if you can run:
  - node --version and get an ouput like: vx.x.x
Yarn instead of npm
- You'll know you've installed yarn right if you can run:
  - yarn --version and get an output like: x.x.x
  - You might need to install it with npm
ganache
- You'll know you did it right if you can run the application and see:
- You can alternatively use ganache-cli or hardhat

Optional Gitpod

If you can't or don't want to run and install locally, you can work with this repo in Gitpod. If you do this, you can skip the clone this repo part.

Setup

Clone this repo

git clone https://github.com/PatrickAlphaC/ethers-simple-storage
cd ethers-simple-storage

Then install dependencies

yarn

Note: You'll notice in our package.json we are using "solc": "0.8.7-fixed". Usually, you'll just be able to do "solc": "0.8.7" to get a specific version, but there was a bit of an issue with that one... You'll find out why we use 0.8.7

Typescript

If you like typescript, run git checkout typescript then run yarn

Usage

Run your ganache local chain, by hitting quickstart on your ganache application

Save the workspace. This way, next time you open ganache you can start the workspace you've created, otherwise you'll have to redo all the steps below.

Copy the RPC SERVER sting in your ganache CLI, and place it into your .env file similar to what's in .env.example.

.env Example:

RPC_URL=http://0.0.0.0:8545

Hit the key on one of the accounts, and copy the key you see and place it into your .env file, similar to what you see in .env.example.

.env Example:

PRIVATE_KEY=11ee3108a03081fe260ecdc106554d09d9d1209bcafd46942b10e02943effc4a

Compile your code

Run

yarn compile

You'll see files SimpleStorage_sol_SimpleStorage.abi and SimpleStorage_sol_SimpleStorage.bin be created.

Run your application

node deploy.js

For WSL users

yarn add ganache

Change Server settings in Ganache

Settings > Server > Host Name

Change Host Name to vEthernet (WSL)

Run your application

node deploy.js

Deploying to a testnet

Make sure you have a metamask or other wallet, and export the private key.

IMPORTANT

USE A METAMASK THAT DOESNT HAVE ANY REAL FUNDS IN IT. Just in case you accidentally push your private key to a public place. I highly recommend you use a different metamask or wallet when developing.

Export your private key and place it in your .env file, as done above.
Go to Alchemy and create a new project on the testnet of choice (ie, Sepolia)
Grab your URL associated with the testnet, and place it into your .env file.
Make sure you have testnet ETH in your account. You can get some here. You should get testnet ETH for the same testnet that you made a project in Alchemy (ie, Sepolia)
Run

node deploy.js

Troubleshooting: Ethers 6.X.X instability

const provider = new ethers.providers.JsonRpcProvider(process.env.RPC_URL)
                                      ^

TypeError: Cannot read properties of undefined (reading 'JsonRpcProvider')

If you are experiencing issues with the latest version of Ethers, ethers ^6.0.2, try

const provider = new ethers.JsonRpcProvider(process.env.RPC_URL)

as providers were migrated to ethers.* in version 6 (previously ethers.providers.*). reference: https://docs.ethers.org/v6/migrating/#migrate-providers

Or you can easily solve the problem by downgrading to a previous version of Ethers, such as ethers 5.7.2.

To downgrade to ethers 5.7.2, run either of the following commands on your command line interface, depending on your package manager:

For npm:

npm install [email protected]

For yarn:

yarn add [email protected]

ethers-simple-storage-fcc's Issues

Solved

Hi all, I am following Patrick's lesson and in lesson 5-6, when he talked about VS code formatting, he mentioned that in settings.json, for "editor.defaultFormatter", we should use "NomicFoundation.hardhat-solidity". But when I tried to do so, this value has been underlined by system, indicating it is not a valid parameter. I tried to change it to "esbenp.prettier-vscode", still my codes are all in white.

The Prettier - Code formatter extension version is v9.10.4.
The Solidity extension version is v0.6.9. (No Solidity + Hardhat extension as in his video)

Please advise. Thank you.

Error: invalid hexlify value

chainId address mismatch

Hello guys, I got to the session were we are to deploy the SimpleStorage.sol contract with only transaction data, but I'm stuck with the following error.

Error: chainId address mismatch (argument="transaction", value={"nonce":3,"gasPrice":20000000000,"gasLimit":10000000,"to":null,"value":0,"data":"0x..."
reason: 'chainId address mismatch',
code: 'INVALID_ARGUMENT',
argument: 'transaction',

Here is the code snippet

const nonce = await wallet.getTransactionCount();
  const tx = {
    nonce: nonce,
    gasPrice: 20000000000,
    gasLimit: 10000000,
    to: null,
    value: 0,
    data: "0x...",
    chainId: 31337,
  };
  const sendTxResponse = await wallet.sendTransaction(tx);
  await sendTxResponse.wait(1);
  console.log(sendTxResponse);

I tried using my ganache Network ID: 5777 as chainId as instructed but still got the same error.
I also tried using 31337 as chainId but it didn't work.

Any Ideas???

Clarification on setting up development environment

Hi guys,

I always have a doubt:

After I have installed all the packages as node, ethers, solc etc in my local project folder, when I create a new folder for a new project do I have to reinstall all the dependecies?

thanks

I do it as the step, but I got an error.

ganache UI doesn't show transactions

I'm having an issue with the ganache UI. I'm fairly certain that my transactions are going through since the nonce of the wallet keeps going up (I think I'm at 3 or 4 now). However, when I view the Transactions tab on Ganache's UI, it shows nothing.

No error messages in the console either.

Any ideas for how I can display the transactions on the Ganache UI?

Error running node deploy.js command in the terminal - Error: Cannot find module

I'm just at the start (6:35:00) of using VSC and can't find a solution. I've tried reinstalling, and restarting, won't work!

When I try to run the deploy.js code using
node deploy.js
in the terminal, I get the following error:

In package.json -> scripts -> compile 'yarn' is redundant and causes the compilation to run twice

Issue : could not detect network with ganache

Hi all !
So I was trying to launch my first blockchain with ganache (hour 7) and I am stuck with the following issue :
"reason: 'could not detect network',
code: 'NETWORK_ERROR',
event: 'noNetwork'
"

I made sure ganache is running, that I have ethers and fs
I don't know where exactly the issue is so I can't make a minimalist code

async function main() {
  const provider = new ethers.providers.JsonRpcProvider(
    "http://127.0.0.1:7545"
  );
  const wallet = new ethers.Wallet(
    "1b8975f86182691cc7a416ed4b6bc04dfabff769922925632232636f5da1c1c4",
    provider
  );
  const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf8");
  const binary = fs.readFileSync(
    "./SimpleStorage_sol_SimpleStorage.bin",
    "utf8"
  );
  const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
  console.log("deploying please wait...");
  const contract = await contractFactory.deploy();
  console.log(contract);
}

Thank you for your help

Compiler version problem in visual studio code

I started visual studio code but usage of latest compiler version is showing error.

I used this:

'''
pragma solidity >=0.8.0 <0.9.0;
'''

'''

I got this error message:

Source file requires different compiler version (current compiler is 0.4.17+commit.bdeb9e52.Emscripten.clang - note that nightly builds are considered to be strictly less than the released versionsolc

'''

Can someone please help me?, Thanks in advance.

ts-node command not found

If we don't have ts-node installed globally its gives the error ts-node command not found. Need to update README.MD to use npx ts-node deploy.ts if using npm or yarn ts-node deploy.ts for yarn.

some typos at line 54, 128

I have seen some typos on line no. 54 and 128. So, I fixed it and created a pull request.
I'm so happy to contribute!

error Command "--base-path" not found.

Hi Fam.
i am at 6:53:10 of the course
Iran this command
yarn --solcjs --bin --abi --include-path node-modules/ --base-path . -o . SimpleStorage.sol

and it shows an error

error Command "--base-path" not found.

version of node.js engine is incompatible with module when I run "yarn add solc"

After I run "yarn add solc" I run to this error:
error [email protected]: The engine "node" is incompatible with this module. Expected version "^14.0.0 || ^16.0.0 || ^18.0.0". Got "19.6.0"
error Found incompatible module.

I think its because I downloaded node.js via homebrew and It automatically got me version 19.6.0
Can you please tell me what is the best way to solve this error? Should I lower my version of node.js back to 18.0.0?
Please anyone write me how to solve this problem I will be waiting :)

Error: missing revert data in call exception

Hi everyone. Right now I'm on Lesson 5 (7:30:00).
When trying to deploy deploy.js I get many errors in the console. The first line is:

Error: missing revert data in call exception; Transaction reverted without a reason string

I was following the course and just double-checked my code with Patrick's, both deploy.js and SimpleStorage.sol
I hate putting a lot of code in my questions, but since I can't determine the place of the issue happening, it's the only way.

Unable to install Solc in my environment [Doesn't show up] (Stuck at Tutorial Moment 6:48:00)

In the tutorial, after running:

yarn add solc

Visual Studio would bring up 2 new packages: (package.json && yarn.lock)

### None of them appear to me after running the exact same command. I ran:

corepack enable

yarn --version
solcjs --version

And I still get nothing. I tried everything, even installing it with

npm install solc

But nothing really brought those files in my visual studio

typescript error - Only a void function can be called with the 'new' keyword

hi everyone

I am trying to switch to ts version of the deploy file in this course.

in the deploy.ts, I am using the decrypt method fromEncryptedJsonSync from the from ethers.Wallet ether js.
unfortunately it works with js but not in ts version.

here is my code and my packages version:

import {ethers } from 'ethers'
import dotenv from 'dotenv'
dotenv.config();
import * as fs from 'fs-extra';


// using Ganache desktop localy to get the a test wallet locally, getting the Private key from it
const ProviderRPC:string = process.env.PROVIDER_RPC !;
const PrivateKeyPassword:string = process.env.PRIVATE_KEY_PASSWORD!;
// abi - bin > files names
const AbiFileName = "SimpleStorage_sol_SimpleStorage.abi"
const BinFileName = "SimpleStorage_sol_SimpleStorage.bin"

async function main() {
    // main scipt to compile code
    //HTTP://127.0.0.1:7545

    // blockchain connection  ( network provider )
    const provider = new ethers.providers.JsonRpcProvider(ProviderRPC)
    //const wallet = new ethers.Wallet(PrivateKey, provider);
    //get the encryptedJsonKey object
    const encryptedJsonKey:string = fs.readFileSync("./.encryptedKey.json", "utf8")
    // decrypt the encryptedJsonKey object  throw passing the pasword  to get the wallet
    console.log(PrivateKeyPassword)
    let wallet:any= new ethers.Wallet.fromEncryptedJsonSync(
        encryptedJsonKey,
        PrivateKeyPassword
    )
    console.log(wallet)
    // connect the wallet with the provider
    wallet = await wallet.connect(provider)

    const abi = fs.readFileSync(`./${AbiFileName}`, "utf8")
    const bin = fs.readFileSync(`./${BinFileName}`, "utf8")

    const contractFactory = new ethers.ContractFactory(abi, bin, wallet)
    console.log("Deploying, Please wait ...")
    const contract = await contractFactory.deploy()
    // specifiy the number of block confirmation that it gonna wait
    await contract.deployTransaction.wait(1)
    console.log(`contract address : ${contract.address}`)

    // store a new favorite number
    const StoreTransactionReceipt = await contract.store("16")
    const StoreTransactionResp = await StoreTransactionReceipt.wait(1)

    // get the favorite number
    const currentFavoriteNumber = await contract.retrieve()
    console.log(`current Favorite Number : ${currentFavoriteNumber.toString()}`)
   
}

main()
    .then(() => {
        console.log("deployment Done!")
        process.exit(0)
    })
    .catch((error) => {
        console.error(error)
        process.exit(1)
    })

the issue is in the line below :

    let wallet:any= new ethers.Wallet.fromEncryptedJsonSync(
        encryptedJsonKey,
        PrivateKeyPassword
    )

the error I am getting in my console

I tried to look into the node_modules/@ethersproject/wallet/src.ts/index.ts file
it gives punch of errors there too, I think maybe it's a typescript version issue or the ethersjs types not working well.
any ideas? :)

ENV Variable not able to read on terminal

Hey there - so when I try to run the deploy.js script with encrypted keys, I try to set the environment variable for PRIVATE_KEY_PASSWORD=PASSWORD in the terminal. For your information, I did not install all the Ubuntu environment for coding hence the terminal I use is still with Windows. I think the problem is that I cannot find anywhere how to pass a "node deploy.js" command with a ENV variable set in the terminal in Windows. Could you help?

Running into a "NETWORK_ERROR" while deploying contract to Goerli

So, I've been following the entire tutorial and was able to run the simple storage contract on Ganache. However, when I try to deploy the same on Goerli through Alchemy, I get this error:

Error: could not detect network (event="noNetwork", code=NETWORK_ERROR, version=providers/5.7.2)

I tried hardcoding the RPC URL and my PRIVATE KEY values into the provider and wallet functions, instead of getting them from the .env file, without any success. Is this an issue with Alchemy's API/ Goerli? Am I missing something?

when watching 8:03:38 ,deploy contract to goeril instead of Ganache , there is error "reason":"cannot estimate gas; transaction may fail or may require manual gas limit"

EncryptedKey and Password not working

When I am trying to deploy contract with password it is show no commend found error
"PRIVATE_KEY_PASSWORD=SAYA123 : The term 'PRIVATE_KEY_PASSWORD=SAYA123' is not
recognized as the name of a cmdlet, function, script file, or operable program. Check the
spelling of the name, or if a path was included, verify that the path is correct and try again."
and also if i tryin to delete PRIVATE_KEY from .env it is also not working.

README.md, SyntaxError: Cannot use import statement outside a module

On video time 8:17:16
README.md

I followed the instructions by commenting the lines

const ethers = require("ethers")
const fs = require("fs-extra")
require("dotenv").config()

and replacing them with

import { ethers } from "ethers"
import * as fs from "fs-extra"
import "dotenv/config"

now, in deploy.ts file

async function main() {
const provider = new ethers.providers.JsonRpcProvider(process.env.RPC_URL)
    const wallet = new ethers.Wallet(process.env.PRIVATE_KEY, provider)
    ...
}

and in encryptKey.ts file

async function main() {
    const wallet = new ethers.Wallet(process.env.PRIVATE_KEY)
    const encryptedJsonKey = await wallet.encrypt(
        process.env.PRIVATE_KEY_PASSWORD,
        process.env.PRIVATE_KEY
    )

<process.env.PRIVATE_KEY> in both files is giving the error

var process: NodeJS.Process
Argument of type 'string | undefined' is not assignable to parameter of type 'BytesLike | ExternallyOwnedAccount | SigningKey'.
  Type 'undefined' is not assignable to type 'BytesLike | ExternallyOwnedAccount | SigningKey'.ts(2345)

I tried uncommenting const ethers = require("ethers"), replacing import { ethers } from "ethers" and the error is gone but when run,

What's wrong here?

Ganache doesn't start RPC server

When I launch Ganache it shows this screen and doesn't start the server

yarn.lock,node_modules and package.jason is not coming

After running the yarn add solc, yarn.lock,node_modules and package.jason is not generating on file side in vs code.

Cant deploy contract to test network.

In section 5 I am right at the part at the very end where I am trying to deploy the contract to the test netwrok and I am getting this error:

Deploying, please wait...
<ref *1> Error: cannot estimate gas; transaction may fail or may require manual gas limit [ See: https://links.ethers.org/v5-errors-UNPREDICTABLE_GAS_LIMIT ] (error={"reason":"cannot estimate gas; transaction may fail or may require manual gas limit","code":"UNPREDICTABLE_GAS_LIMIT","error":{"reason":"processing response error",

It deployed just fine when connecting to ganache. The video also never mentioned anything about inputting a gas fee at this point either

So im trying to run this command and getting this error
error fires right after conrtact.deploy()

deploy.js is throwing a no network error

I am at 7:07:38 in the course where Patrick first runs the deploy.js using the command node deploy.js. Instead of getting the contract details, it throws an error stating "could not detect network". Any help would be much appreciated.
the entire error is as follows:

Lesson 5: TXRejectedError: the tx doesn't have the correct nonce.

Hello, I am receiving the error below when trying to deploy "deploy.js":

TXRejectedError: the tx doesn't have the correct nonce.

Here is the code:

  const nonce = await wallet.getTransactionCount();
  const tx = {
    nonce: nonce,
    gasPrice: 20000000000,
    gasLimit: 1000000,
    to: null,
    value: 0,
    data: "Long Byte Code",
    chainId: 1337,
  };
  const sentTxResponse = await wallet.sendTransaction(tx);
  await sentTxResponse.wait(1);
  console.log(sentTxResponse);

Anyone have any ideas why I still get this error even when using await wallet.sendTransaction(tx) for the nonce?
"Long Byte Code" stores the Byte code from the byte file. It has been removed for space.

Code works without transactionResponse.wait() using Ganache, but doesn't work on real testnet without it.

''' const currentFavNum = await contract.retrieve();
console.log(Current favorite number is: ${currentFavNum});
console.log("Updating favorite number...");
let transactionResponse = await contract.store(7);
// let transactionReceipt = await transactionResponse.wait();

const updatedFavNum = await contract.retrieve();
console.log(`Updated favorite number is: ${updatedFavNum}`);'''

As the screenshot shows, the favNum is not updated if I comment out the '''transactionResponse.wait()''', but then it works perfectly when I add it back. Wondering why?

ps: it only happens when I'm using Goerli. Ganache works fine with or without '''transactionResponse.wait()'''

Delete private_key_password from .env file

Hi everyone, I have a question about private key encryption. In the tutorial after generating "encryptedKey.json" we can delete PRIVATE_KEY_PASSWORD from .env file.

But in deploy.js we refer to process.env.PRIVATE_KEY_PASSWORD to create wallet. In my case, the program cannot find this variable since we have deleted it from .env already.

I'm wondering do we still need to keep PRIVATE_KEY_PASSWORD in .env? Or is it because I have done something wrong? Thanks.

The term 'PRIVATE_KEY_PASSWORD=password' is not recognized as a name of a cmdlet, function, script file, or executable program.

I'm using VScode in windows 10 with admin rights.
Regarding instructions on 7:47 on the video. I cannot define the variable PRIVATE_KEY_PASSWORD when writing
"PRIVATE_KEY_PASSWORD=password node deploy.js" For some reason I cannot define any variable on the integrated powershell terminal of the VScode, executed with or without admin rights.
This is the error message that I have when writing that command line:

PS E:\mycodefolder> PRIVATE_KEY_PASSWORD=password node deploy.js

Error:
"PRIVATE_KEY_PASSWORD=password: The term 'PRIVATE_KEY_PASSWORD=password' is not recognized as a name of a cmdlet, function, script file, or executable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again."

I would greatly thank in advance any sort of help, I'm sure this is just a newbie problem that I encountered.
