# Kredits Contracts
|
|
|
|
This repository contains the Solidity smart contracts organized as
|
|
[Aragon](https://hack.aragon.org/) apps and JavaScript API wrapper for [Kosmos
|
|
Kredits](https://wiki.kosmos.org/Kredits).
|
|
|
|
It is based on [aragonOS](https://hack.aragon.org/docs/aragonos-intro.html) and
|
|
follows the aragonOS conventions. Aragon itself uses the [Truffle
|
|
framework](http://truffleframework.com/) for some things.
|
|
|
|
## Development
|
|
|
|
### Installation
|
|
|
|
All requirements are defined in `package.json`.
|
|
|
|
$ npm install
|
|
|
|
Each of the aragon apps are separate packages:
|
|
|
|
$ cd apps/[app]
|
|
$ npm install
|
|
|
|
You can use `npm run install-all` to install all app dependencies at once.
|
|
|
|
### Local development chain
|
|
|
|
For local development it is recommended to use
|
|
[ganache](http://truffleframework.com/ganache/) to run a local development
|
|
chain. Using the ganache simulator no full Ethereum node is required.
|
|
|
|
We use the default aragon-cli devchain command to confgure and run a local
|
|
development ganache.
|
|
|
|
$ npm run devchain (or aragon devchain --port 7545)
|
|
|
|
To clear/reset the chain use (e.g. if you run out of funds on your devchain)
|
|
|
|
$ npm run devchain -- --reset (or aragon devchain --port 7545 --reset)
|
|
|
|
We default to port 7545 for development to not get in conflict with the default
|
|
Ethereum RPC port.
|
|
|
|
### Bootstrap
|
|
|
|
1. Run an Ethereum node and ipfs
|
|
|
|
$ npm run devchain
|
|
$ ipfs daemon
|
|
|
|
2. Deploy each app to the devchain
|
|
|
|
(make sure you've run `npm install` for every app - see installation)
|
|
$ npm run deploy:apps
|
|
|
|
3. Deploy a new KreditsKit and create a new DAO with the latest app versions
|
|
|
|
$ npm run deploy:kit
|
|
$ npm run deploy:dao
|
|
|
|
4. Execute seeds to create demo contributors, contributons, etc. (optional)
|
|
|
|
$ npm run seeds
|
|
|
|
**Step 2-4 is also summarized in `npm run bootstrap`**
|
|
|
|
If you want to reset your local setup:
|
|
|
|
$ npm run reset // deploys a new kit and a new DAO
|
|
$ npm run reset:hard // deploys all apps and does reset
|
|
|
|
## Contract architecture
|
|
|
|
Contracts are organized in independent apps (see `/apps`) and are developed and
|
|
deployed independently. Each app has a version and can be "installed" on the
|
|
Kredits DAO independently.
|
|
|
|
|
|
|
|
A DAO can be deployed using the `scripts/deploy-kit.js` script or with the
|
|
`npm run deploy:dao` command. This deploys a new Kredits DAO, installs the
|
|
latest app versions and sets the required permissions.
|
|
|
|
See each app in `/apps/*` for details.
|
|
|
|
|
|
## Helper scripts
|
|
|
|
`scripts/` contains some helper scripts to interact with the contracts from the
|
|
CLI. _At some point these should be moved into a real nice CLI._
|
|
|
|
To run these scripts use `truffle exec`. For example: `truffle exec
|
|
scripts/add-proposal.js`.
|
|
|
|
Some scripts are also defined as npm script, see package.json.
|
|
|
|
### cli.js
|
|
|
|
Call any function on any contract:
|
|
|
|
$ truffle exec scripts/cli.js
|
|
|
|
### repl.js
|
|
|
|
Similar to cli.js but only provides a REPL with an initialized `kredits`
|
|
instance.
|
|
|
|
$ truffle exec scripts/repl.js
|
|
|
|
### add-{contributor, contribution, proposal}.js
|
|
|
|
Script to add a new entries to the contracts using the JS wrapper
|
|
|
|
$ truffle exec scripts/add-{contributor, contribution, proposal}.js
|
|
|
|
### list-{contributors, contributions, proposals}.js
|
|
|
|
List contract entries
|
|
|
|
$ truffle exec scripts/list-{contributors, contributions, proposals}.js
|
|
|
|
### send-funds.js
|
|
|
|
Sends funds to an address. Helpful in development mode to for example fund a
|
|
metamask account.
|
|
|
|
$ truffle exec scripts/send-funds.js
|
|
|
|
### seeds.js
|
|
|
|
Run seeds defined in `config/seeds.js`.
|
|
|
|
$ truffle exec scripts/seeds.js
|
|
or
|
|
$ npm run seeds
|
|
|
|
### current-address.js
|
|
|
|
Prints all known DAO addresses and the DAO address for the current network
|
|
|
|
$ truffle exec scripts/current-address.js
|
|
or
|
|
$ npm run dao:address
|
|
|
|
### deploy-kit.js
|
|
|
|
Deploys a new KreditsKit that allows to create a new DAO
|
|
|
|
$ truffle exec script/deploy-kit.js
|
|
or
|
|
$ npm run deploy:kit
|
|
|
|
`ENS` address is required as environment variable.
|
|
`DAO_FACTORY` can optionally be set as environment variable. (see aragon)
|
|
|
|
### new-dao.js
|
|
|
|
Creates and configures a new DAO instance.
|
|
|
|
$ truffle exec script/new-dao.js
|
|
or
|
|
$ npm run deploy:dao
|
|
|
|
KreditsKit address is load from `lib/addresses/KreditsKit.json` or can be
|
|
configured through the `KREDITS_KIT` environment variable.
|
|
|
|
### deploy-apps.sh
|
|
|
|
Runs `npm install` for each app and publishes a new version.
|
|
|
|
$ ./scripts/deploy-apps.sh
|
|
or
|
|
$ npm run deploy:apps
|
|
|
|
## Deployment
|
|
|
|
### Apps deployment
|
|
|
|
To deploy a new app version run:
|
|
|
|
$ aragon apm publish major --environment=NETWORK_TO_DEPLOY
|
|
|
|
### KreditsKit
|
|
|
|
deploy the KreditsKit as Kit to create new DAOs
|
|
|
|
$ truffle exec scripts/deploy-kit.js --network=NETWORK_TO_DEPLOY
|
|
|
|
### Creating a new DAO
|
|
|
|
make sure all apps and the KreditsKit are deployed, then create a new DAO:
|
|
|
|
$ truffle exec scripts/new-dao.js --network=NETWORK_TO_DEPLOY
|
|
|
|
## ACL / Permissions
|
|
|
|
## Upgradeable contracts
|
|
|
|
We use aragonOS for upgradeablity of the different contracts. Refer to the
|
|
[aragonOS upgradeablity documentation](https://hack.aragon.org/docs/upgradeability-intro)
|
|
for more details.
|
|
|
|
### Example
|
|
|
|
1. Setup (see #Bootstrap)
|
|
1. Deploy each contract/apps (see `/apps/*`)
|
|
2. Create a new DAO (see scripts/deploy-kit.js)
|
|
2. Update
|
|
1. Deploy a new Version of the contract/app (see `/apps/*`)
|
|
2. Use the `aragon dao upgrade` command to "install" the new version for the DAO
|
|
(`aragon dao upgrade <DAO address> <app name>`)
|
|
|
|
## Known Issues
|
|
|
|
When resetting ganache Metamask might have an invalid transaction nonce and
|
|
transactions get rejected. Nonces in Ethereum must be incrementing and have no
|
|
gap.
|
|
|
|
To solve this reset the metamask account (Account -> Settings -> Reset Account)
