network.js

A node.js library for interacting with the MyBit Network SDK.

Setup

Install dependencies.
npm install

Start blockchain

We have included a local blockchain with our contracts already deployed. The API creates instances of our contracts deployed on the local chain and exposes them for easy interaction. To start the chain simply open up a terminal in the base directory and enter the following command:
./start_chain

Import package

In your node.js file import this package (@mybit/network.js):
const Network = require('@mybit/network.js');
Network takes several objects in its contructor. You need to pass it a web3 object, the addresses of the platform contracts, and the block number that the platform was first deployed on. For the address and block number you can get those by importing the contracts package:
const Contracts = require('@mybit/contracts');
To instantiate a network object you can do the following:
const web3 = new Web3(new Web3.providers.HttpProvider(`wss://mainnet.infura.io/v3/${INFURA_API_KEY}`));
const addresses = Contracts.addresses.mainnet;
const block = Contracts.block.mainnet;
const network = new Network(web3, addresses, block);

Async/await

Since these functions interact with the Ethereum blockchain, everything is done asynchronously. The easiest way to work with asynchronous functions is with the async/await syntax:
const Network = require('@mybit/network.js');
​
(async function() {
var crowdsales = await Network.getOpenCrowdsales();
console.log('Open crowdsales: ', crowdsales);
});
Check out Hello Network for more examples.

Functions

As of version 0.0.5, these are the functions currently available from network.js:

Full Contracts

api() returns ( contract instance )
The api function returns the entire API.sol contract, which contains many getter functions for accessing variable on Database.sol​
dividendToken( tokenAddress ) returns ( contract instance )
This function takes a contract address for an already deployed DividenToken.sol contract, instantiates the contract, and exposes all of its public functions.

Owner Functions

addOperator( object ) returns ( bytes32 )
This function takes an object with the following values: operatorID (address), name (string), ipfs (string), referrer (address), and owner (address) and registers the operator in the Operators.sol contract from the owner address. It returns the operatorID that will be needed for any crowdsale creation. Note, this function will not work if the owner address is a contract.

User Functions

Operator Functions

addModel( object ) returns ( bool )
This function takes an object that contains a bytes32 operatorID, a string of the asset name, a string of the ipfs hash, a bool on whether they accept the cryptocurrency indicated, a bool whether they payout in the cryptocurrency, and a address of the token those bools reference.
acceptToken( object ) returns ( bool )
An operator must specify the currencies that they accept. The object must contain an id (bytes32) of the asset model and a token (address). This function sets the asset model as accepting the indicated token. For accepting Ether, do not pass the token variable.
Note, an asset can accept as many currencies as they want.
payoutToken( object ) returns ( bool )
An operator must specify the currencies that they payout with. The object must contain an id (bytes32) of the asset model and a token (address). This function sets the asset model as paying with the indicated token. For paying with Ether, do not pass the token variable.
Note, an asset can payout as many currencies as they want.
issueDividends( object ) returns ( bool )
To pay out dividends to investors, an operator can call this function. Pass the following: asset (address), amount (uint256), and account (address). The function determines if the asset takes Ether or an ERC-20 token. If the account does not have a sufficient balance in the required payment method, the function will fail.

Asset Manager Functions

createAsset( object ) returns ( object )
To start a crowdsale to fund a new asset you must pass this function and object that contains the following paremeters:
{
assetManager: address, //Address of the asset manager (this function will be called from their account)
assetURI: string, //The URI where information about this asset can be found
ipfs: string, //The hash of the IPFS file location
modelID: bytes32, //Model ID
fundingLength: uint256, //Funding time in seconds
amountToRaise: uint256, //Funding goal
assetManagerPercent: uint256, //A number less than 100: The percentage to be received by the AssetManager
escrow: uint256, //The amount being kept in collateral priced in the paymentToken
paymentToken: address, //The token being used to pay the collateral. It will be converted to MYB
fundingToken: address//Optional: if this asset is being funded with an ERC-20 token, you must pass the address
}
The functions returns an object that contains _assetID, _assetManager, _assetURI, and _tokenAddress.
payout( object ) returns ( object )
After a successful funding, one must call this function to withdraw funds and asset tokens to the asset manager and the platform. You must pass the following asset (address) and from (address).

Investor Functions

fundAsset( object ) returns ( address )
To contribute to a crowdsale call this function and pass the following object:
{
asset: address, //The address of the asset you want to fund
amount: uint, //The amount you want to contribute
paymentToken: address, //The token you'd like to pay with. Will be converted to the token used by the asset
investor: address, //The address from which you will contribute
}

Getter Functions

getAssetsByInvestor( address ) returns ( array )
Pass an address and get back an array of assetIDs owned by that investor.
getAssetsByManager( address ) returns ( array )
Pass an address and get back an array of assetIDs managed by that asset manager.
getAssetsByOperator( address ) returns ( array )
Pass an address and get back an array of assetIDs operated by that operator.
getTotalAssets() returns ( array )
Get an array of all assetIDs on the network.
getOpenCrowdsales() returns ( array )
Get an array of all assetIDs that are currently seeking funding.
getFundingTimeLeft( assetID ) returns ( uint )
Pass an assetID and get back the time in seconds until the crowdsale finishes. If the crowdsale is already finished, you'll receive 0.
getFundingGoal( assetID ) returns ( uint )
Pass an assetID and get back the funding goal for the asset. If the asset is funded, you'll get back the total supply of tokens.
getFundingProgress( assetID ) returns ( uint )
Pass an assetID and get back the current amount that the asset has been funded.
getAssetOperator( assetID ) returns ( address )
Pass an assetID and get back the address of the operator.
getAssetManager( assetID ) returns ( address )
Pass an assetID and get back the address of the asset manager.
getAssetInvestors( assetID ) returns ( array )
Pass an assetID and get back an array of all the addresses that have funded it.
