Liqwid SDK

A JavaScript SDK for Ethereum and the Liqwid Protocol. Wraps around Ethers.js. Works in the web browser and Node.js.

This SDK is in open beta, and is constantly under development.

Liqwid Protocol

Simple methods for using the Liqwid protocol.

const liqwid = new Liqwid(window.ethereum) // in a web browser

// Ethers.js overrides are an optional 3rd parameter for `supply`
const trxOptions = { gasLimit: 250000, mantissa: false }

(async function() {

  console.log('Supplying ADA to the Liqwid protocol...')
  const trx = await liqwid.supply(Liqwid.ADA, 1)
  console.log('Ethers.js transaction object', trx, trxOptions)

})().catch(console.error)

Install / Import

Web Browser

<script type="text/javascript"
        src="https://cdn.jsdelivr.net/npm/@liqwid2021/liqwid-sdk@latest/dist/browser/liqwid.min.js"></script>

<script type="text/javascript">
    window.Liqwid; // or `Liqwid`
</script>

Node.js

npm install @liqwid2021/liqwid-sdk

const Liqwid = require('@liqwid2021/liqwid-sdk');

// or, when using ES6

import Liqwid from '@liqwid2021/liqwid-sdk';

Instance Creation

The following are valid Ethereum providers for initialization of the SDK.

new Liqwid(window.ethereum)

new Liqwid('http://127.0.0.1:8545')

new Liqwid()

new Liqwid('rinkeby')

// Init with private key (server side)
new Liqwid('https://rinkeby.infura.io/v3/_your_project_id_', {
  privateKey: '0x_your_private_key_', // preferably with environment variable
});

// Init with HD mnemonic (server side)
new Liqwid('rinkeby', {
  mnemonic: 'clutch captain shoe...', // preferably with environment variable
})

Constants and Contract Addresses

Names of contracts, their addresses, ABIs, token decimals, and more can be found in src/constants.ts.

Addresses, for all networks, can be easily fetched using the getAddress function, combined with contract name constants.

console.log(Liqwid.LQ, Liqwid.qLQ, Liqwid.ADA, Liqwid.qADA)
// LQ, qLQ, ADA, qADA

const address = Liqwid.util.getAddress(Liqwid.ADA);
