L2Dashboard

This project serves as a tool for understanding the distribution and evolution of value locked across different blockchain networks, providing insights into the growth and adoption of various Layer 1 and Layer 2 solutions in the blockchain ecosystem. It's used to get an understanding of how L2beats can be built using open source data.

L2Beats-style Data Dashboard for L2s

Project Overview This project is a web-based dashboard that visualizes and compares Total Value Locked (TVL) across multiple blockchain networks. It provides a real-time, interactive visualization of how much value (in USD) is locked in various blockchain protocols over time.

Technical Architecture

Uses the DeFi Llama API (api.llama.fi) to fetch historical TVL data Endpoint: https://api.llama.fi/v2/historicalChainTvl/{chainName} Data is retrieved for multiple chains including:

Ethereum Base Arbitrum Mantle Blast Linea World coin Zircuit

Technical Stack

Pure HTML/JavaScript implementation (no frameworks) Chart.js library for data visualization Responsive design using modern CSS All-in-one single page application

Interactive Elements

Hover tooltips showing exact TVL values Clickable legend to toggle individual chains Responsive x-axis with auto-scaling date labels Dynamic y-axis labels converting values to M/B (millions/billions)

Data Processing

Automatic conversion of Unix timestamps to readable dates TVL normalization to millions/billions for readability Handling of missing or null values Error handling for failed API requests Minimum value threshold to prevent logarithmic scale issues
