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
