# Kredits Contracts
|
|
|
|
This repository contains the Solidity smart contracts and the JavaScript API
|
|
wrapper for [Kosmos Kredits](https://wiki.kosmos.org/Kredits).
|
|
|
|
## Development
|
|
|
|
### Installation
|
|
|
|
#### App dependencies
|
|
|
|
All requirements are defined in `package.json`.
|
|
|
|
$ npm install
|
|
|
|
### Local development chain
|
|
|
|
We use [hardhat](https://hardhat.org/) as development environment for the
|
|
smart contracts.
|
|
|
|
To run a local development chain run:
|
|
|
|
$ npm run devchain # or: hardhat node --network hardhat
|
|
|
|
### Bootstrap
|
|
|
|
1. Run an Ethereum node and ipfs
|
|
|
|
$ npm run devchain
|
|
$ ipfs daemon
|
|
|
|
2. Compile contracts and build ABIs
|
|
|
|
(compiled artifacts will be in `/artifacts`)
|
|
$ npm run build
|
|
|
|
3. Deploy new upgradable contract proxies
|
|
|
|
$ npm run deploy:dao
|
|
|
|
4. Execute seeds to create demo contributors, contributions, etc. (optional)
|
|
|
|
$ npm run seeds
|
|
|
|
**Step 2-4 is also summarized in `npm run bootstrap`**
|
|
|
|
5. Show contract addresses
|
|
|
|
$ cat lib/addresses.json
|
|
|
|
## Fund a local development account
|
|
|
|
If you need to fund development accounts with devchain coins:
|
|
|
|
$ npm run fund # or hardhat fund --network localhost
|
|
|
|
## Contract architecture
|
|
|
|
We use the [OpenZeppelin hardhat
|
|
proxy](https://www.npmjs.com/package/@openzeppelin/hardhat-upgrades) for
|
|
deploying and managing upgradeable contracts. (see `scripts/create-proxy.js`)
|
|
|
|
Each contract is independent and is connected to its dependencies by storing
|
|
the addresses of the other contracts.
|
|
|
|
## 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 `hardhat run`. For example: `hardhat run
|
|
scripts/list-contributors.js --network localhost`. (NOTE: add `--network
|
|
localhost` or the network you want to use)
|
|
|
|
Some scripts are also defined as npm script, see `package.json`.
|
|
|
|
### repl/console
|
|
|
|
Similar to cli.js but only provides a REPL with an initialized `kredits`
|
|
instance.
|
|
|
|
$ hardhat console --network localhost
|
|
|
|
### add-{contributor, contribution, proposal}.js
|
|
|
|
Script to add a new entries to the contracts using the JS wrapper
|
|
|
|
$ hardhat run scripts/add-{contributor, contribution, proposal}.js --network localhost
|
|
|
|
### list-{contributors, contributions, proposals}.js
|
|
|
|
List contract entries
|
|
|
|
$ hardhat run scripts/list-{contributors, contributions, proposals}.js --network localhost
|
|
|
|
### seeds.js
|
|
|
|
Run seeds defined in `config/seeds.js`.
|
|
|
|
$ npm run seeds
|
|
|
|
### Get the contract addresses
|
|
|
|
All contract addresses are stored in `lib/addresses.json`
|
|
|
|
$ cat lib/addresses.json
|
|
|
|
## Upgradeable contracts
|
|
|
|
We use OpenZeppelin for an upgradeable contracts:
|
|
[https://www.npmjs.com/package/@openzeppelin/hardhat-upgrades](https://www.npmjs.com/package/@openzeppelin/hardhat-upgrades)
|
|
|
|
Refer to the OpenZeppelin README and `scripts/create-proxy.js`
|
|
|
|
[OpenZeppelin Step by Step guide](https://forum.openzeppelin.com/t/openzeppelin-upgrades-step-by-step-tutorial-for-hardhat/3580)
|
|
|
|
For an upgrade example checkout `scripts/upgrade-example.js`
|
|
|
|
|
|
## Deployment to other networks
|
|
|
|
Deployable networks are configured in the `hardhat.config.js`.
|
|
|
|
To deploy to those networks provide the `--network` argument to the hardhat
|
|
commands, e.g. `--network rsk`.
|
|
|
|
Please note that some npm scripts combine multiple hardhat commands. In those
|
|
cases the hardhat commands needs to be run manually with the `--network`
|
|
argument. (=> don't use `npm run bootstrap`)
|
|
|
|
Set a `DEPLOY_KEY` environment variable with the private key (HEX) which will
|
|
be used as a root/deploy account
|
|
|
|
Typical deployment flow:
|
|
|
|
$ npm run build
|
|
$ hardhat run scripts/create-proxy.js --network rsk
|
|
# OR with deploy key:
|
|
$ DEPLOY_KEY=0xsomething hardhat run scripts/create-proxy.js --network rsk
|
|
$ # commit the new addresses in the addresses.json file if needed
|
|
|
|
To run the console on one of the non localhost networks you can also just pass
|
|
on the --network argument.
|
|
|
|
$ hardhat console --network rsk
|
|
|
|
|
|
## 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)
|
