Why I built it

Working on Cosmos SDK chains, every new testnet meant either running a full explorer stack locally or going without visibility into validators, governance and block times. I wanted something disposable: paste an RPC endpoint, explore, done.

What it does

• Live dashboard with real-time block and transaction subscriptions
• Search for blocks, transactions and accounts
• Validators with uptime, commission and voting power
• Governance proposals and voting results
• Chain parameters and IBC transfer tracking
• A locked mode that pins one RPC endpoint, for a public explorer of a specific chain

How it’s built

React, TypeScript and Vite in the browser, talking to the chain over a WebSocket RPC with CosmJS. No backend, no indexer, no database.

The hard part

The protobuf layer. CosmJS doesn’t cover every module, so some governance and staking queries needed hand-written decoders. Keeping type safety through nested messages and Cosmos’s heavy use of the Any type took longer than the UI.
