@pagedao/core v0.3.3

@pagedao/core

Core library for PageDAO Hub with blockchain connections and price calculations.

Features

• Blockchain connections to Ethereum, Optimism, Base, and Osmosis
• Price calculation for PAGE token across all networks
• TVL calculation and weight distribution
• Caching mechanisms for efficient data retrieval

Installation

npm install @pagedao/core
# or
yarn add @pagedao/core

Usage

import { fetchPagePrices, fetchAllTVL, calculateTVLWeights } from '@pagedao/core';

// Get PAGE token prices across all networks
const prices = await fetchPagePrices();
console.log(prices);

// Get TVL data
const tvlData = await fetchAllTVL(prices);
console.log(tvlData);

// Calculate weights based on TVL
const weights = calculateTVLWeights(tvlData);
console.log(weights);
