klips/blockchain/eth/truffle-solidity/README.md

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...

Development Deploy

npx truffle develop
truffle(develop)> migrate

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

Give yourself test Ethereum with the Ropsten ETH Faucet

To deploy to ropsten test network, and verify using truffle-verify-plugin -

npx truffle migrate --network ropsten
npx truffle run verify Migrations --network ropsten

For a guide on how I configured this project, see Knoats - Solidity
