Single-Collateral Sai

Installation
Single-Collateral Dai support in Dai.js is implemented as a plugin. The SCD plugin is also available as an npm package and its source code can be found on Github.
npm install @makerdao/dai-plugin-scd
import { ScdPlugin } from '@makerdao/dai-plugin-scd';
// or
const { ScdPlugin } = require('@makerdao/dai-plugin-scd');
Quick example
The code below creates a CDP, locks ETH into it, and draws out Sai.
import Maker from '@makerdao/dai';
import { ScdPlugin } from '@makerdao/dai-plugin-scd';
​
async function openLockDraw() {
  const maker = await Maker.create("http", {
    plugins: [ScdPlugin],
    privateKey: YOUR_PRIVATE_KEY,
    url: 'https://kovan.infura.io/v3/YOUR_INFURA_PROJECT_ID'
  });
​
  await maker.authenticate();
  const cdpService = await maker.service('cdp');
  const cdp = await cdpService.openCdp();
​
  await cdp.lockEth(0.25);
  await cdp.drawSai(50);
​
  const debt = await cdp.getDebtValue();
  console.log(debt.toString); // '50.00 SAI'
}
​
openLockDraw();
The services and objects below are used to work with Single-Collateral Sai.
​CDP Service​
​Collateralized Debt Position​
​System Status​
​Token Conversion​
openCdp()
Returns: promise (resolves to new CDP object once mined)
openCdp() will create a new CDP, and then return the CDP object, which can be used to access other CDP functionality. The promise will resolve when the transaction is mined.
const cdpService = await maker.service('cdp');
const newCdp = await cdpService.openCdp();
getCdp(int id)
Returns: promise (resolves to CDP object)
getCdp(id) creates a CDP object for an existing CDP. The CDP object can then be used to interact with your CDP.
const cdpService = await maker.service('cdp');
const cdp = await cdpService.getCdp(614);
Once you have an instance of a CDP, you can use CDP instance methods to read its state and perform actions.
