|
|
|
|
|
|
|
|
A template project for getting started working on the Ethereum blockchain.
|
|
|
|
|
This project comes with basic packages for compiling and deploying Solidity contracts with Truffle.
|
|
|
|
|
|
|
|
|
|
Run `cp example.secrets.json secrets.json` and fill out the copied `secrets.json` with your information.
|
|
|
|
|
|
|
|
|
|
From this directory, run `npm install` to install required packages.
|
|
|
|
|
|
|
|
|
|
From there, we can create any contracts and deploy to development or public networks...

### Public Network Deploy
|
|
|
|
|
|
|
|
|
|
To deploy, you need ETH on a wallet connected to ropsten. Metamask is the wallet I use.
|
|
|
|
|
I explain how to configure metamask on ropsten on [Knoats - Solidity](https://knoats.com/books/c/page/solidity)
|
|
|
|
|
|
|
|
|
|
Give yourself test Ethereum with the [Ropsten ETH Faucet](https://faucet.ropsten.be)
|
|
|
|

|
|
|
To deploy to ropsten test network, and verify using `truffle-verify-plugin` -
|
2021-05-03 14:46:36 -04:00
|
|
|
|
|
|
|
|
```asm
|
|
|
|
|
npx truffle migrate --network ropsten
|
|
|
|
|
npx truffle run verify Migrations --network ropsten
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
