Metacoin

Simple project to test ethereum/source-verify's chain monitor.

• compiles Truffle's metacoin contracts with truffle compile
• uploads the generated metadata and corresponding Solidity sources to IPFS (via Infura gateway)
• deploys to either Ropsten or Rinkeby

A running source-verify monitor will auto-detect this deployment and save entries to the metadata repository for the chain / addresses displayed in the Truffle migrations output.

Install

npm install

Configure

You'll need to create a .env file in the project root and set values for

• an Infura project ID
• the private key to an account with a testnet ether balance

INFURA_ID=1d13168ffb894ad2827f...
PRIVATE_KEY=A4AA598CD030E2E22A9A3C...

Deploy

Your choice of:

npm run deploy:ropsten
npm run deploy:rinkeby
npm run deploy:goerli
