Monoscan Block Explorer

Monoscan is the multi-chain block explorer for Monolythium networks, available at monoscan.xyz. It provides a web interface to browse blocks, transactions, addresses, and validators, along with a REST API for programmatic access and real-time data streaming via Server-Sent Events.

Supported Networks

Network	Cosmos Chain ID	EVM Chain ID	Status
Sprintnet	`mono-sprint-1`	262146	Active
Testnet	`mono_6940-1`	6940	Planned
Mainnet	`mono_6941-1`	6941	Planned

Features

Block Explorer

The UI provides pages for browsing chain data, organized by network:

Dashboard -- Network overview with latest blocks and chain status
Blocks -- Paginated block list and individual block detail pages showing height, timestamp, proposer, and transaction count
Transactions -- Transaction list and detail pages with hash, status, fees, and event data
Addresses -- Address lookup with Cosmos and EVM balances, transaction history
Validators -- Active validator set, individual validator detail, earnings
Consensus -- Consensus participation data
Governance -- On-chain governance proposals
Supply -- Token supply information
IBC -- Inter-Blockchain Communication data
CosmWasm -- CosmWasm contract data (when applicable)
Faucet -- Testnet token faucet interface
Wallet Helper -- Address format conversion and wallet utilities
Uptime -- Validator uptime monitoring
Milestones -- Network milestone tracking
Parameters -- Chain parameter display
Nodes -- Network node information
State Sync -- State sync configuration helper
Search -- Universal search across blocks, transactions, and addresses

Searching

Monoscan supports searching by:

Transaction hash -- Both EVM-format (0x...) and Cosmos-format hashes
Address -- Bech32 (mono1...) and hex (0x...) formats, with automatic conversion between the two
Block height -- Numeric block height

The search endpoint returns the match type and a redirect path:

{
  "type": "tx",
  "network": "sprintnet",
  "query": "0xabc...",
  "redirect": "/sprintnet/tx/0xabc..."
}

Validator Metrics

Validators are displayed with two key performance metrics computed over rolling windows of recent blocks:

Proposed

The number of blocks in the selected window where the validator was chosen as block proposer. Validators with greater stake are selected more frequently, so higher proposed counts generally correlate with higher voting power.

Signed

The number of block commits the validator has signed in the selected window. This metric reflects validator availability and consensus participation.

Metric Windows

Three window sizes are available for monitoring validator performance at different time scales:

Window	Purpose
200 blocks	Short-term; useful for detecting sudden changes in participation
1,000 blocks	Medium-term; balanced view of recent behavior
5,000 blocks	Long-term; overall reliability and uptime trends

Inactive Validators

Validators that are jailed (missed blocks) or tombstoned (double-signing) are displayed separately and do not affect active set statistics.

Validator Earnings

Monoscan tracks validator earnings data accessible through the API:

Individual validator earnings: GET /api/validator/{network}/{valoper}/earnings
Aggregate validator earnings: GET /api/validators/earnings

Known Accounts

A curated list of known accounts (treasury, fee collector, deployer, etc.) is available through the API with real-time balance information for both Cosmos and EVM address formats.

Richlist

The richlist shows top wallet addresses ranked by balance, with pagination and search:

Rank, address, balance, and percentage of total supply
Search for a specific address to find its rank

Live Block Producers Tape

The explorer displays a real-time horizontal tape showing the last 24 blocks and their proposers. Each card shows:

Block height
Time elapsed since creation
Proposer moniker (validator display name)
Transaction count

The tape updates automatically using Server-Sent Events (SSE), so new blocks appear without page refresh.

Faucet

Monoscan includes an integrated testnet faucet for requesting test tokens.

Using the API

Example: Get Latest Block

curl https://monoscan.xyz/api/latest

Response:

{
  "network": "sprintnet",
  "height": 1234567,
  "block_time": "2025-01-15T12:00:00Z",
  "tx_count": 3,
  "chain_height": 1234567,
  "sync_status": "synced"
}

Example: Look Up an Address

curl https://monoscan.xyz/api/address/sprintnet/mono1abc123...

Response includes both Cosmos (bech32_addr) and EVM (hex_addr) representations of the address along with balances in both formats.

Example: Stream Live Blocks

curl -N https://monoscan.xyz/api/stream/recent-blocks

Returns a continuous SSE stream. Each event contains the latest block data as JSON.

Privacy-First Design

All data displayed in Monoscan comes from indexed blockchain data, not direct node queries. This approach ensures:

No node hostnames or IP addresses are exposed
All data is derived from public, immutable blockchain records
The explorer maintains security and privacy standards

URL Format

Monoscan URLs follow a consistent pattern:

https://monoscan.xyz/{network}/tx/{hash}       -- Transaction
https://monoscan.xyz/{network}/address/{addr}  -- Address
https://monoscan.xyz/{network}/block/{height}  -- Block
https://monoscan.xyz/{network}/validator/{valoper} -- Validator

Networks -- Chain IDs and RPC endpoints
API Reference -- Direct Cosmos REST API access
Block Explorer -- General explorer information
