Scrinium — The future of portfolio investment

node yarn npm truffle ganache-cli solidity

Installation

We recommend using the latest versions node, npm и yarn.

To install the dependencies (after repo cloning), you must run the following command yarn install (yarn should be already globally istalled in your system).

Configuring

Networks

By default, project is configured to use the development network:

{
  host: '127.0.0.1',
  port: 8545,
  network_id: 5777,
  gas: 3 * 10**6,
  gasPrice: 20 * 10**9
}

For overriding any values of the development network, you must create a file ./config/networks/development.js which exports the overridden directives, for example:

module.exports = {
  host: '172.0.0.1',
  port: 8646,
  gasPrice: 10 * 10**9
}

To add a new network, you must create a file named as the network, for example, ./config/networks/live.js:

module.exports = {
  host: '8.8.8.8',
  port: 8747,
  network_id: '*',
  gas: 2 * 10**6,
  gasPrice: 10 * 10**9
}

By default transactions are signing by the first unlocked account of the node. For specifiyng a different account, you must add the from: <unlocked_address> directive.

Deploy

By default, it comes with deployment configuration for develop and development networks — ./config/deploy/develop.js and ./config/deploy/development.js.

Property Required Type Description
commissionsAddress · String Address for LiquidityProvider commissions

Development

You may run Remix IDE by executing of yarn remix command. It will run on http://localhost:8080. To mount local directory with contracts you should click on the chain icon in the IDE and accept prompt.

Testing

To run tests you need to execute following commands:

yarn truffle develop
# Command above will start Truffle Develop terminal
# with already running Ganache private node on 9545 port
truffle(develop)> test

Note: tests for Scrinium.sol contract may fail because of hardcoded ICO timestamps.

Deployment

Before starting the deployment of smart contracts, you must have running Ethereum node (Geth, for example, or Ganache) with enabled JSON-RPC option.

The network configuration ./config/networks/<network_name>.js and deploy configuration ./config/deploy/<network_name>.js should exist.

Base account (field from in the network configuration) should be unlocked.

In case of Ganache

# 1. Run Ganache in a separate tab
[PORT=<port>] yarn ganache # 8545 port by default

# 2. Run migrations (contracts that are already migrated will be rewritten)
[NETWORK=<network_name>] yarn migrate # development network on 8545 port by default

In case of Geth

# 1. Unlock base account
geth attach <protocol>://<host>:<port> --exec "personal.unlockAccount(eth.accounts[0], <accountPassPhrase>)"

# 2. Run migrations (contracts that are already migrated will be rewritten)
NETWORK=<network_name> yarn migrate

# 3. Connect to the console for checking deployed contracts
geth attach <protocol>://<host>:<port> --preload ./preload-<network_name>.js

# 4. Try to run some commands such as:
> scrinium.balanceOf(eth.accounts[0]);
> balances.balanceOf(eth.accounts[0])
> platform.getTradeIds()

In case of Infura

You may deploy contracts via Infura (to Ropsten, Rinkeby, Kovan or Mainnet networks) by running yarn migrate with additional environment variables:

NETWORK=<network_name> \
INFURA_ACCESS_TOKEN=<infura_access_token> \
<NETWORK_NAME>_PRIVATE_KEY=<account_private_key> \
yarn migrate

    • TRUFFLE_MIGRATIONS_OMIT=<migration_number_1>,...,<migration_number_N> — specified migrations will be omitted
    • INFURA_ACCESS_TOKEN=<infura_access_token>
    • <INFURA_NETWORK_NAME>_PRIVATE_KEY=<account_private_key>
