# Faucet Webpage
A simple webpage for Sepolia Testnet's faucet.
It's HW1 for 1112 NCNU CSIE "Principles and Practice of Blockchains"
link to Metamask and create a transaction to the smart contract to get SepoliaETH.
![](docs/Screenshot_20230226_025506.png)
## Project Setup
```sh
npm install
```
### fill in your smart contract's address
```sh
cp .env.example .env
vim .env
'''
VITE_BANK_ADDR = "YOUR BANK ADDRESS"
'''
```
### Compile and Hot-Reload for Development
```sh
npm run dev
```
### Compile and Minify for Production
```sh
npm run build
```
## Notice
Now, I am not sure of difference between `window.ethereum` & `web3`
I use `window.ethereum` to send transaction, check accounts, check network and use `web3` to encode ABI.
I am not sure whether it's a suitable implementation
