Bounty #2303 - wRTC Solana Bridge Dashboard (60 RTC)

Claimed by: kuanglaodi2-sudo

Implementation

Built a real-time wRTC Bridge monitoring dashboard at dashboard/wrtc-bridge-dashboard.html:

• Total RTC locked (RustChain Bridge API)
• wRTC circulating supply (Solana RPC)
• Recent wraps (RTC to wRTC) and unwraps (wRTC to RTC) via /bridge/ledger
• Bridge fee revenue (0.1% of volume)
• Price chart via DexScreener/Raydium + Chart.js
• Bridge health (4 endpoints: Solana RPC, RustChain API, Solana Contract, Ledger Sync)
• Lock state breakdown bar chart
• Chain volume bar chart
• Auto-refresh every 30s

Deploy target: rustchain.org/bridge or standalone.
