Setup

Install dependencies:

nvm use # Should install node 10.16.0
npm install -g ganache-cli
npm install

Ganache

Run Ganache:

ganache-cli --port 9545 --deterministic

Any time you shutdown ganache, you will need to do zos push and zos create to deploy the project into the blank blockchain.

npx zos session --network local --from 0x1df62f291b2e969fb0849d99d9ce41e2f137006e --expires 3600
zos push
zos create XPoap --init initialize --args '"Poap","POAP","https://poap.xyz",[]'

Truffle Commands

To run a console:

npx truffle console --network local

To run tests:

npx truffle test

Useful Commands

Working with ZeppelinOS

Session

Start by creating a session:

npx zos session --network local --from 0x1df62f291b2e969fb0849d99d9ce41e2f137006e --expires 3600

This creates a "connection" that will be used for every zos command. We define which network to connect, which account to use by default for all transaction and when it expires (3600 seconds after last used).

If no current session exists, or it its expired we need to create one.

Create or Upgrade Contracts

When we create a new contract run:

npx zos add MyContract

To upgrade a current contract (change the code of it)

npx zos update MyContract

After any change we need to push the changes:

npx zos push

add and update only change the contract instance, but they don't actually release/create an instance of that contract. To create an instance we do:

npz zos create MyContract --init initialize --args 42,hitchhiker
