dai-plugin-mcd
一个 Dai.js 插件，用于与 多抵押 Dai 合约
Example usage
import { McdPlugin, ETH, REP, DAI } from '@makerdao/dai-plugin-mcd';
import Maker from '@makerdao/dai';
import { createCurrency } from '@makerdao/currency';
import { tokenAddress, tokenAbi } from 'someOtherTokenData';
const TOK = createCurrency('TOK');
const maker = await Maker.create('http', {
// ...other configuration...
plugins: [
[
McdPlugin,
{
// omit this option to get the default set:
// ETH-A, ETH-B, REP-A
cdpTypes: [
{ currency: ETH, ilk: 'ETH-A' },
{ currency: REP, ilk: 'REP-A' },
{ currency: TOK, ilk: 'TOK-Z', address: tokenAddress, abi: tokenAbi },
]
}
]
]
});
await maker.service('proxy').ensureProxy();
const cdpManager = maker.service('mcd:cdpManager');
const cdp1 = await cdpManager.openLockAndDraw('REP-A', REP(50), DAI(1000));
const cdp2 = await cdpManager.openLockAndDraw('ETH-A', ETH(50), DAI(1000));
const cdp3 = await cdpManager.openLockAndDraw('TOK-Z', TOK(50), DAI(1000));

Developer notes
MCD 合约将每秒的稳定费存储在一个名为 tax 的变量中 作为 1.X _ 10^27 形式的数字（例如 1000000000472114805215157978），以及 称为 repo 的变量中的基本利率，形式为 0.X _ 10^27 的数字。
在此插件中，getAnnualStabilityFee() 和获取 getAnnualBaseRate 函数将这些值转换为返回年度的十进制表示 率（例如 0.015 和 0.01）。
从顶级 dai.js 目录运行测试。
Local Development
由于 Babel7 处理转译的方式，在本地开发和导入此插件时无法使用 yarn link。 我们建议改用 yalc。 我们还发现名为 sane 的观察器工具很有用。
运行步骤：
- In this directory run
sane "yalc publish && cd [INSERT THE DIRECTORY OF THE PROJECT THAT IS IMPORTING THIS PLUGIN] && yalc link @makerdao/dai-plugin-mcd" src --wait=3

A Dai.js plugin for interacting with the multi-collateral dai contracts
Example usage

import Maker from '@makerdao/dai';
import { createCurrency } from '@makerdao/currency';
import { tokenAddress, tokenAbi } from 'someOtherTokenData';
const TOK = createCurrency('TOK');
const maker = await Maker.create('http', {

{ currency: TOK, ilk: 'TOK-Z', address: tokenAddress, abi: tokenAbi },
]
}
]
]
});
await maker.service('proxy').ensureProxy();
const cdpManager = maker.service('mcd:cdpManager');
const cdp1 = await cdpManager.openLockAndDraw('REP-A', REP(50), DAI(1000));
const cdp2 = await cdpManager.openLockAndDraw('ETH-A', ETH(50), DAI(1000));
const cdp3 = await cdpManager.openLockAndDraw('TOK-Z', TOK(50), DAI(1000));

Developer notes
The MCD contracts store the stability fee per second in a variable called tax as a number in the form 1.X _ 10^27 (e.g. 1000000000472114805215157978), and the base rate in a variable called repo as a number in the form 0.X _ 10^27.
In this plugin, the getAnnualStabilityFee() and get getAnnualBaseRate functions convert those values to return a decimal representation of the yearly rates (e.g. 0.015 and 0.01).
Run the tests from the top-level dai.js directory.
Local Development
Due to the way that Babel7 handles transpilation it is not possible to use yarn link when locally developing this plugin, and importing it. We recommend using yalc instead. We've also found that a watcher tool called sane is helpful.
Steps to Run:
- In this directory run
sane "yalc publish && cd [INSERT THE DIRECTORY OF THE PROJECT THAT IS IMPORTING THIS PLUGIN] && yalc link @makerdao/dai-plugin-mcd" src --wait=3
