Meme Factory EVM Package

This repository contains MemeFactory smart contracts packaged as a reusable EVM Package. You can deploy them as-is, or extend to suit your needs to build custom contracts and more complex decentralized systems.

Install

npm install memefactory-contracts

Packaged contracts

• DSAuth
• DSGuard
• EternalDb
• Registry
• MiniMeTokenFactory
• DankToken
• MemeToken
• MemeFactory

Development

prerequisites

You need ZeppelinOS comand-line interface installed:

npm install --global zos

Using this package

Create a new ZeppelinOS project, and add the memefactory-contracts EVM package:

zos init MyProject
zos link memefactory-contracts

Start session with a network called local (defined in truffle-config), using an address different from the default:

zos session --network local --from <address> --expires 3600

Deploy all the added logic contracts to the network (note that this step is only needed on local networks, when working on public networks ZeppelinOS will automatically used the pre-deployed implementation contracts):

zos push --deploy-dependencies

Developing and contributing to this package

Initialize project:

zos init memefactory-contracts

Add contracts:

zos add DSAuth:ds-auth
zos add DSGuard:ds-guard
zos add EternalDb:meme-registry-db
zos add Registry:meme-registry
zos add App:token-factory
zos add DankToken:DANK
zos add MemeToken:meme-token
zos add MemeFactory:meme-factory

Start session with a testrpc network called ganache (defined in truffle-config):

zos session --network ganache --from <address> --expires 3600

Deploy all the added logic contracts to the network:

zos push --force

Publish the contracts:

zos publish --network ganache --from <address>

Updating packaged contracts

Update to a new version of the package and deploy changes to the logic contracts:

zos link memefactory-contracts@new-version
zos push --deploy-dependencies

Deploy updated instances of the contracts to interact with:

zos update meme-factory

Deploy upgradeable instances of the contracts:

OWNER=<address>
DB=$(zos create meme-registry-db --init initialize)
REGISTRY=$(zos create meme-registry --init --args $DB,$OWNER)
TOKEN_FACTORY=$(zos create token-factory)
DANK_TOKEN=$(zos create DANK --init --args $TOKEN_FACTORY,1000000000000000000000000000,$OWNER)
MEME_TOKEN=$(zos create meme-token --init --args $REGISTRY)
MEME_FACTORY=$(zos create meme-factory --init --args $REGISTRY,$DANK_TOKEN,$MEME_TOKEN,1)

Interact with the contracts

---

NOTE

When interacting with deployed contracts use a different address than that of the owner (admin) addressed used when creating it. The transparent proxy pattern posits that the calls from the admin address will not be delegated to the proxy contract holding the logic.

---

npx truffle console --network ganache

var address='contract-instance-address';
memeFactory=MemeFactory.at(address)
var opts = {from: 'address'};
memeFactory.version(opts)
