BTCD Analytics Dashboard

Real-time risk analytics for the Elastos BeL2 ecosystem. The first third-party dashboard for BTCD — Bitcoin's stablecoin on the Elastos Smart Chain.

Live: btcd-dashboard.vercel.app

Features

• BTCD Supply & Holders — Live on-chain data via ESC RPC and Blockscout
• Peg Health Tracking — Infrastructure ready for DEX pool indexing as BTCD liquidity grows
• ELA Market Data — Price, market cap, and CoinGecko ranking
• ESC Chain Health — Transaction count and block time from Blockscout
• BTC Yield Comparison — Aave V3 WBTC supply/borrow APY (live on-chain reads)
• BTCFi Landscape — TVL comparison across Babylon Genesis, Core, Stacks, BOB, and Elastos
• Fault-Tolerant Architecture — Each data card degrades independently; one API failure doesn't break the dashboard

Architecture

• Next.js 14 App Router with Server Components and ISR caching
• Zero client-side API calls — All data fetched server-side, cached via { next: { revalidate } }
• Native fetch() for all RPC calls (preserves Next.js ISR cache)
• Viem for ABI decoding only (not network calls)
• Recharts for data visualization
• Tailwind CSS for styling
