        # Solidity Learning

This repository contains Solidity smart contract projects and CTF-like challenges for learning purposes.

Built and tested with [Hardhat](https://hardhat.org).

_Some of the old projects were built and tested with now deprecated [Truffle Suite](https://trufflesuite.com) using now deprecated [Ganache](https://trufflesuite.com/ganache) local test network and [Sepolia](https://www.infura.io) public test network._

## Ethernaut

Web: [ethernaut.openzeppelin.com](https://ethernaut.openzeppelin.com)

GitHub: [OpenZeppelin/ethernaut](https://github.com/OpenZeppelin/ethernaut)

Built and tested with [Hardhat](https://hardhat.org). Work in progress...

From [\\Ethernauth\\hardhat](https://github.com/ivan-sincek/solidity-learning/blob/main/Ethernaut/hardhat), run the unit tests:

```fundamental

npm install

npx hardhat compile

npx hardhat test --network localhost --parallel

```

---

Unit tests (Hardhat):

* [\\Ethernaut\\hardhat\\test\\ethernaut.js](https://github.com/ivan-sincek/solidity-learning/blob/main/Ethernaut/hardhat/test/ethernaut.js) (1-25)

_\[Deprecated\]_ Unit tests (Truffle):

* [\\Ethernaut\\truffle_suite_deprecated\\test\\ethernaut.js](https://github.com/ivan-sincek/solidity-learning/blob/main/Ethernaut/truffle_suite_deprecated/test/ethernaut.js) (level 1-20)

## Upgradeable Contracts

Built and tested with [Hardhat](https://hardhat.org). Work in progress...

## Fundraiser

__Built and tested with now deprecated [Truffle Suite](https://trufflesuite.com) using now deprecated [Ganache](https://trufflesuite.com/ganache) local test network and [Sepolia](https://www.infura.io) public test network.__

Work in progress... Also, need to migrate to Hardhat.

Install Truffle:

```fundamental

npm install -g truffle

```

Make sure to start a local test network using Ganache on port `8545`.

From [\\Fundraiser\\truffle](https://github.com/ivan-sincek/solidity-learning/blob/main/Fundraiser/truffle), run the unit tests:

```fundamental

npm install

truffle compile

truffle test --network development --show-events

```

From [\\Fundraiser\\client](https://github.com/ivan-sincek/solidity-learning/blob/main/Fundraiser/client), run the client web application:

```fundamental

npm install

npm start

```

Navigate to the client web application with your preferred web browser.

To run the unit tests on [Sepolia](https://www.infura.io) public test network, do the following:

\[1\] Specify your [Infura](https://www.infura.io) (Sepolia) API key and [MetaMask](https://metamask.io) wallet mnemonic inside [\\Fundraiser\\truffle\\example.env](https://github.com/ivan-sincek/solidity-learning/blob/main/Fundraiser/truffle/example.env) file.

\[2\] Rename the file from `example.env` to `.env`.

\[3\] In your MetaMask wallet, [switch](https://moralis.io/how-to-add-the-sepolia-network-to-metamask-full-guide) to the Sepolia public test network.

\[4\] Get some Sepolia ETH from [infura.io/faucet/sepolia](https://www.infura.io/faucet/sepolia) to your MetaMask wallet.

\[5\] Finally, run:

```fundamental

truffle test --network sepolia --show-events

```
