mygnoscan

A fast, minimal blockchain explorer for gno.land that actually shows useful data.

Built on the tx-indexer GraphQL API with a local SQLite cache for dependency analysis.

Features

• Realm inspector — source, imports, dependents, callers, MsgRun references
• Dependency graph — interactive D3 visualization of what imports what
• Transaction inspector — full message details, events, errors
• Usage tracking — direct MsgCall, indirect imports from other contracts, MsgRun references
• Smart caching — SQLite stores computed dependency graphs and usage stats
• Single binary — Go backend with embedded frontend, no Node.js
