 # 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.
+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
 
-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 [hardhat](https://hardhat.org/) as development environment for the
+smart contracts.
 
-We use the default aragon-cli devchain command to confgure and run a local
-development ganache.
+To run a local development chain run:
 
-    $ npm run devchain (or aragon devchain --port 7545)
-
-To clear/reset the chain use:
-
-    $ 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.
+    $ npm run devchain # or: hardhat node --network hardhat
 
 ### Bootstrap
 
-1. Run an Ethereum node and ipfs
+1. Run an EVM node and ipfs
 
         $ npm run devchain
         $ ipfs daemon
 
-2. Deploy each app to the devchain
+2. Compile contracts and build ABIs
 
-        (make sure you've run `npm install` for every app - see installation)
-        $ npm run deploy:apps
+        (compiled artifacts will be in `/artifacts`)
+        $ npm run build
 
-3. Deploy a new KreditsKit and create a new DAO with the latest app versions
+3. Deploy new upgradable contract proxies
 
-        $ npm run deploy:kit
         $ npm run deploy:dao
 
-4. Execute seeds to create demo contributors, contributons, etc. (optional)
+4. Execute seeds to create demo contributors, contributions, etc. (optional)
 
         $ npm run seeds
 
 **Step 2-4 is also summarized in `npm run bootstrap`**
 
-If you want to reset your local setup:
+5. Show contract addresses
 
-        $ npm run reset // deploys a new kit and a new DAO
-        $ npm run reset:hard // deploys all apps and does reset
+        $ 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
+
+## Specs / Testing
+
+With a local development chain running:
+
+    $ hardhat test
+
+If you add or change contract code, please make sure to add and/or adapt tests
+accordingly. Don't worry, it's easy! You can use existing tests as a template
+for new ones.
 
 ## 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.
-
-![](docs/kredits-diagram.png)
-
-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.
+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 `truffle exec`. For example: `truffle exec
-scripts/add-proposal.js`.
+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.
+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
+### repl/console
 
 Similar to cli.js but only provides a REPL with an initialized `kredits`
 instance.
 
-    $ truffle exec scripts/repl.js
+    $ hardhat console --network localhost
 
 ### 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
+    $ hardhat run scripts/add-{contributor, contribution, proposal}.js --network localhost
 
-### list-{contributor, contribution, proposal}.js
+### list-{contributors, contributions, proposals}.js
 
 List contract entries
 
-    $ truffle exec scripts/list-{contributor, contribution, proposal}.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
+    $ hardhat run scripts/list-{contributors, contributions, proposals}.js --network localhost
 
 ### seeds.js
 
 Run seeds defined in `config/seeds.js`.
 
-    $ truffle exec scripts/seeds.js
-    or
     $ npm run seeds
 
-### current-address.js
+### Get the contract addresses
 
-Prints all known DAO addresses and the DAO address for the current network
+All contract addresses are stored in `lib/addresses.json`
 
-    $ 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
+    $ cat lib/addresses.json
 
 ## 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.
+We use OpenZeppelin for an upgradeable contracts:
+[https://www.npmjs.com/package/@openzeppelin/hardhat-upgrades](https://www.npmjs.com/package/@openzeppelin/hardhat-upgrades)
 
-### Example
+Refer to the OpenZeppelin README and `scripts/create-proxy.js`
 
-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>`)
+[OpenZeppelin Step by Step guide](https://forum.openzeppelin.com/t/openzeppelin-upgrades-step-by-step-tutorial-for-hardhat/3580)
 
-## Known Issues
+For an upgrade example checkout `scripts/upgrade-example.js`
 
-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)
+## 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
