## Requirements
* Node.js >= 12
* @openzeppelin/contracts = 2.4.0
#### Global install
* ganache-cli >= 6.9.1
* truffle = 5.1.3
## Instalation
**Download and install Node.js v12.x and npm.**
* Node.js
**Using Ubuntu**
```sh
$ curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
$ sudo apt-get install -y nodejs
```
**Using Debian, as root**
```sh
$ curl -sL https://deb.nodesource.com/setup_12.x | bash -
$ apt-get install -y nodejs
```
**Clone the repo**
```sh
$ git clone https://gitlab.com/deca-currency/dcc.git
$ cd dcc
```
**Install the dependencies**
```sh
$ npm install
```
**Install ganache-cli**
```sh
$ sudo npm install -g ganache-cli
```
**Install truffle**
```sh
$ sudo npm install -g truffle@5.1.3
```
## Testing the Smart Contract:
- can see the test in pipelines or you can run it locally
#### Running locally
- open shell and execute "./run-rpc.sh" (remember change /usr/local/bin/ganache-cli to your path)
```sh
$ ./run-rpc.sh
```
- open second shell, and execute
```sh
$ truffle tests
```
## Class Diagram ERC20 Token generated with [sol2uml](https://github.com/naddison36/sol2uml)
<p align="center">
<img src="uml/diagram.png" width="720" />
</p>
## Specification
### Methods
Apart from the [ERC20 standard](https://eips.ethereum.org/EIPS/eip-20) methods that our token complies, we introduce some
improvements, either for security or others that match DECA specific requirements.
**Notes:**
* The following specifications use syntax from Solidity (0.5.12)
#### owner
Returns the address of the current owner.
```sh
function owner() public view returns (address payable)
```
#### isOwner
Returns true if the caller is the current owner.
```sh
function isOwner() public view returns (bool)
```
#### transferOwnership
Can only be called by the current owner.
```sh
function transferOwnership(address payable newOwner) public onlyOwner
```
#### updateCCDBAddress
Updates the official orbitDB address for carbon credits.
Can Only be updated by the current owner
```sh
function updateCCDBAddress(string memory newCCDBAddress) public onlyOwner
```
#### transferAnyERC20Token
Owner can transfer out any accidentally sent ERC20 tokens
```sh
function transferAnyERC20Token(address payable tokenAddress, uint tokens) public onlyOwner returns (bool success)
```
#### getETH
Close down the ICO and claim the Ether.
```sh
function getETH() public onlyOwner { require(now >= endDate); owner().transfer(address(this).balance); }
```
## DECA Promotion Dates
Now, based on the total Ethereums we got by the ICO (ETHTS)
and considering our promodates which are:
| PROMO | TIME (weeks) | DECA TOKENS PER ETH |
|--------|--------------|---------------------|
| preICO | 1 | 300 |
| Bonus1 | 2 | 275 |
| Bonus2 | 3 | 250 |
| ICO | 5 | 225 |
# In order to run tests:
- npm i -g ganache-cli
- edit last line at run-rpc.sh, fix to the correct path to your ganache-cli
- open shell and execute "./run-rpc.sh"
- open second shell, and execute "truffle tests
