W Scan

W Scan is a self‑hosted Blockscout explorer for W Chain. It runs the latest Blockscout backend (v8.11) with a frontend based on v2 plus custom UI improvements. It supports both W Chain Mainnet and Testnet and includes the full Blockscout feature set.

OverviewCopy Anchor Link

• Networks: W Chain Mainnet and W Chain Testnet
• Chain IDs: Mainnet 171717, Testnet 71117
• Explorer URLs:
  • Mainnet: https://scan.w-chain.com
  • Testnet: https://scan-testnet.w-chain.com
• Core features: address/transaction/block/token search, decoded input data, internal txs, logs, contract verification, ABI publishing, read/write contract, token pages, labels, and API access.

Quick StartCopy Anchor Link

1. Open the appropriate URL (Mainnet or Testnet).
2. Use the top search bar to paste an address, transaction hash, block number/hash, or token contract.
3. Click results to open detail pages with balances, transfers, logs, decoded calls, and more.
4. Switch networks via the network selector in the header.

Address PagesCopy Anchor Link

• Summary: shows total balance, token holdings, and recent transactions.
• Tokens: view ERC‑20 balances and transfer history per token.
• Internal txs: inspect value transfers created within contract executions.
• Labels: community or system labels may appear for known contracts.

Transaction DetailsCopy Anchor Link

• Overview: status, gas usage, fee, nonce, and timestamps.
• Decoding: function signature and input parameters are decoded when ABI is known.
• Logs: event topics and parameters; filter or expand for details.
• Internal txs: visualize internal calls/value movements during execution.

Token PagesCopy Anchor Link

• Metadata: name, symbol, decimals, holders, and transfers.
• Holders: ranked list of addresses and their balances.
• Analytics: supply and transfer charts when available.

Smart ContractsCopy Anchor Link

• Verify: publish source code to enable full decoding and ABI access.
• ABI: once verified, ABI is available to clients and the explorer.
• Read/Write: interact with verified contracts directly from the UI (read state or send transactions).

Network SwitchingCopy Anchor Link

• Use the header selector to switch between Mainnet and Testnet.
• Links and searches remain network‑scoped; ensure you’re on the correct network before sharing URLs.

API & ExportsCopy Anchor Link

• W Scan exposes Blockscout’s standard APIs for indexing and querying chain data.
• For endpoints, authentication options, rate limits, CSV exports, and GraphQL/REST usage, see the official Blockscout documentation at https://docs.blockscout.com.

TroubleshootingCopy Anchor Link

• Data not found: confirm you’re on the right network (Mainnet vs Testnet).
• Undecoded input: verify the contract and publish the ABI to enable decoding.
• Pending tx: network congestion may delay inclusion; retry with appropriate gas settings.
• Indexing lag: recent blocks may take a moment to index; refresh after a short interval.
