Block explorer for the Solen blockchain. Inspired by Etherscan's familiar interface.

• Dashboard — chain stats (block height, total blocks/txs/events) with live-updating latest blocks
• Block explorer — browse blocks with epoch, age, tx count, gas used, proposer
• Block detail — full block info with prev/next navigation
• Transactions — browse recent transactions with status badges (success/failed)
• Events — view contract events with emitter and topic
• Account pages — balance, nonce, code hash, transaction history, smart account detection
• Network switcher — toggle between devnet, testnet, and mainnet
• Search — look up blocks by height or accounts by ID
• Auto-refresh — data polls every 3-5 seconds

• Node.js 18+
• A running Solen node (cargo run --bin solen-node from the ~/solen/ directory)
