This repository contains sample DApps and smart contracts developed for Ethereum platform. All smart contracts are deployed on Ethereum's Rinkeby testnet. Metamask browser extension is used for testing and development
Some of the tests may require Metamask/Mist due to account accesses, however pages like crc32.html may be tested just using Infura.
Please check out the *.js files in app directory. By setting infuraAPIKey variable you may execute most of the tests without needing Metamask/Mist

• Ethereum network access via web3 provider may be checked using app/conn.* files
• CRC32 DApp in app/crc32.* interfaces with a IEEE 802.3 compliant CRC32 calculator smart contract
• Wallet DApp in app/wallet.* interfaces with the NoNameToken, a StandardBurnable ERC20 token smart contract

Please refer to the following step-by-step guides to setup and start development with Truffle

• How to setup Truffle for macOS and Linux
• How to build Geth on macOS and Linux

Basic commands for development and testing are as follows

# everytime you had a fresh checkout, get dependencies via
$ npm install

# compile smart contracts
$ truffle compile

# test smart contracts
$ truffle test

# create an .env file to store wallet seed and infura api keys in project root dir
$ cat .env
MNEMONIC=<wallet seed phrases (may be Metamask)>
INFURA_API_KEY=<infura api key>

# deploy smart contracts on various networks
$ truffle migrate --network localhost
$ truffle migrate --network mainnet
$ truffle migrate --network ropsten
$ truffle migrate --network rinkeby

# serve static content with lite-server at localhost:3000
$ npm run dev
