This package provides several examples to use DeFi features.

Usage

1. npm i decentralized-finance-defi
2. try some of the following examples in your code

Get Current Gas Price Info

const gasPriceInfo = await DeFiService.getGasPriceInfo()
console.log(gasPriceInfo.fastest)

Get Compound Account Data

const { DeFiService } = require("decentralized-finance-defi")

const walletAddress = '0xA63CD0d627c34Ce3958c4a82E6bB12F7b9C1c324'
const accountInfo = await DeFiService.getCompoundAccountData(walletAddress)

console.log(`The collateral value in ETH is: ${accountInfo.total_collateral_value_in_eth.value}.`)

Get Crypto Currency Prices (API Key Required)

const { DeFiService } = require("decentralized-finance-defi")

const pricesWithTimeStamp = DeFiService.getPriceDataWithTimeStamp()

// There will be ETH :)
console.log(pricesWithTimeStamp[1])

Transfer Ether

require('dotenv').config() // this ensures process.env. ... contains your .env file configuration values
    
const { DeFiService } = require("decentralized-finance-defi")

const fromWalletAddress = process.env.SENDER_WALLET_ADDRESS
const toWalletAddress = process.env.RECEIVER_WALLET_ADDRESS
const amountInETH = 1
const senderPrivateKey = process.env.SENDER_WALLET_PRIVATE_KEY

await DeFiService.transferEther(fromWalletAddress, toWalletAddress, amountInETH, senderPrivateKey)

Deposit Ether to Compound

require('dotenv').config() // this ensures process.env. ... contains your .env file configuration values
    
const { DeFiService } = require("decentralized-finance-defi")

const amountOfEtherToBeDeposited = 1
const senderPrivateKey = process.env.SENDER_WALLET_PRIVATE_KEY
const gasLimit = 250000
const web3ProviderURL = process.env.PROVIDER_URL // e.g. https://mainnet.infura.io/v3/yourinfuraprojectid

await DeFiService.depositEtherToCompound(amountOfEtherToBeDeposited, senderWalletPrivateKey, gasLimit web3ProviderURL)

Borrow Ether from Compound

require('dotenv').config() // this ensures process.env. ... contains your .env file configuration values
    
const { DeFiService } = require("decentralized-finance-defi")

const amountOfDAIToBeBorrowed = 100
const walletPrivateKey = process.env.SENDER_WALLET_PRIVATE_KEY
const gasLimit = 250000
const web3ProviderURL = process.env.PROVIDER_URL // e.g. https://mainnet.infura.io/v3/yourinfuraprojectid

await DeFiService.borrowDAIFromCompound(amountOfDAIToBeBorrowed, walletPrivateKey, gasLimit, web3ProviderURL)

Swap DAI to Ether via Uniswap

require('dotenv').config() // this ensures process.env. ... contains your .env file configuration values
    
const { DeFiService } = require("decentralized-finance-defi")

const amountOfDAIToBeSwapped = 50
const walletAddress = process.env.SENDER_WALLET_ADDRESS
const walletPrivateKey = process.env.SENDER_WALLET_PRIVATE_KEY
const web3ProviderURL = process.env.PROVIDER_URL // e.g. https://mainnet.infura.io/v3/yourinfuraprojectid

await DeFiService.swapDAIToETH(amountOfDAIToBeSwapped, walletAddress, walletPrivateKey, web3ProviderURL)
