impermax-filter

This repo provide a simple filter function for those using the Impermax dapp.

Motivation

As of today, Impermax still needs to implement a filter feature for their markets. There is no easy way to select only a single token or token list, nor order the markets by supply, borrow or farm APR.

How-to Guide

There is no installation for this. You need to use your browser's Dev Tools console (F12).

• Open Impermax dapp.
• Once on markets page, after all markets are loaded, open Dev Tools console (F12).
• Paste impermaxFilter function from filter.js or filter.min.js into the console.
• Call the function using the tokenList and order (and optionally rearrangeDOM) arguments.
• Done.

Arguments

impermaxFilter(tokenList, order, rearrangeDOM);

tokenList: Array containing strings for each token you want to filter in the search.

order: String for desired ordering mode. Allowed values: supply, borrow, farm. When informing supply or farm the order will be descending (as in higher is better) and if borrow the order will be ascending (as lower is better).

rearrangeDOM: If set to true, The function will filter and rearrange the DOM elements in the page itself. Default to false.

Sample call

impermaxFilter(['USDC', 'USDT', 'MAI', 'DAI'], 'supply');

Response

The response will be an Array containing the ordered and filtered list of market pairs.

[
    {
        "token": The token for this entry,
        "pair": The pair of token from the liquidity pool,
        "source": Where the liquidity pool is hosted,
        "supply": Supply APR,
        "borrow": Borrow APR,
        "farm": Farm APR,
        "href": URL at Impermax for the market,
        "row": Row element in the DOM
    },
    ...
]

If you set rearrangeDOM to true, the page itself will be changed. Check sample below, filtered by stablecoins only (USDC, USDT, DAI, MAI) and ordered by Supply APR.
