BlockSage

BlockSage is a Web3 intelligence tool designed to enhance your blockchain data analysis. It utilizes several key dependencies to provide precise token metrics, secure environment management, external data fetching, and extensive logging capabilities.

Features

• Token Metrics: Fetch and calculate token decimals and total supply.
• Wallet Token Balance: Retrieve the balance of a specific token for any wallet.
• Current ETH Price: Fetch the current Ethereum price from external APIs.
• Extensive Logging: Keep track of operations and errors through detailed logs.

Installation

npm install blocksage

Usage

First, ensure you have a .env file with your Web3 provider URL:

WEB3_PROVIDER_URL=https://mainnet.infura.io/v3/YOUR_PROJECT_ID

Then, you can use BlockSage as follows:

const BlockSage = require('blocksage'); const sage = new BlockSage(process.env.WEB3_PROVIDER_URL);

// Fetch token metrics async function getTokenMetrics() { const metrics = await sage.getTokenMetrics('<TOKEN_ADDRESS>'); console.log(metrics); }

// Get wallet token balance async function getWalletTokenBalance() { const balance = await sage.getWalletTokenBalance('<WALLET_ADDRESS>', '<TOKEN_ADDRESS>'); console.log(balance); }

// Fetch current ETH price async function getCurrentEthPrice() { const price = await sage.fetchCurrentEthPrice(); console.log(price); }

getTokenMetrics(); getWalletTokenBalance(); getCurrentEthPrice();
