Releasing a new index token

When releasing a new index token make sure to add it to the tvl provider. So that the provider reflects the total TVL over all Index's products.

New components for an index token

Make sure to check the different custom providers for necessary changes e.g.

• add/update components for ic21 in the nav provider

Examples

Each indicator has its own provider. The following indicators are currently provided and return the according data for an Index token.

• Market Cap (NAV * supply)
• Market Price
• Net Asset Value (NAV)
• (Current) Supply
• TVL (for all Index products)
• (24h) Volume

With just a few lines you can setup any of the providers and fetch the required data.

The first example shows a full example with imports etc. Those are left out for all following ones.

MarketCap

import { providers } from "ethers"
import {
  CoinGeckoService,
  IndexMarketCapProvider,
} from "@indexcoop/analytics-sdk"
const index = "0x7C07F7aBe10CE8e33DC6C5aD68FE033085256A84" // icETH
const rpcProvider = new providers.JsonRpcProvider(url)
const coingecko = new CoinGeckoService(coingeckoApiKey)
const provider = new IndexMarketCapProvider(rpcProvider, coingecko)
const marketCap = await provider.getMarketCap(index)

Markt Price

const coingecko = new CoinGeckoService(coingeckoApiKey)
const provider = new IndexPriceProvider(coingecko)
const price = await provider.getPrice(index, chainId)

NAV

const coingecko = new CoinGeckoService(coingeckoApiKey)
const provider = new IndexNavProvider(rpcProvider, coingecko)
const nav = await provider.getNav(index)

Supply

const provider = new IndexSupplyProvider(rpcProvider)
const supply = await provider.getSupply(index)

24h Volume

import { CoinGeckoService, IndexVolumeProvider } from "@indexcoop/analytics-sdk"
const chainId = 1
const index = "0x7C07F7aBe10CE8e33DC6C5aD68FE033085256A84" // icETH
const coingecko = new CoinGeckoService(coingeckoApiKey)
const provider = new IndexVolumeProvider(coingecko)
const volume = await provider.get24hVolume(index, chainId)

AnalyticsProvider

To fetch all analytics data for a token at once use the IndexAnalyticsProvider.

const address = "0x7C07F7aBe10CE8e33DC6C5aD68FE033085256A84" // icETH
const provider = new IndexAnalyticsProvider(rpcProvider, coingeckoService)
const analyticsData = await provider.getAnalytics(address)

TVL

Returns TVL for all of the Index products combined.

const provider = new IndexTvlProvider(rpcProvider, coingeckoService)
const supply = await provider.getTvl()
