Using the Block Explorer

The Liberty Chain Block Explorer provides a comprehensive interface for inspecting transactions, addresses, tokens, and smart contracts on the network. It is powered by Blockscout, a widely adopted open-source explorer used by many EVM chains.

Access the explorer at https://testnet-explorer.lcx.com.

Searching the Explorer

The search bar at the top of the explorer accepts several types of queries. Simply paste or type your query and press Enter:

Wallet or contract address — Enter a full 0x... address to view its balance, transaction history, and associated tokens.
Transaction hash — Paste a transaction hash to see full details including status, gas usage, and decoded input data.
Block number — Enter a block number to view the block's transactions, timestamp, and metadata.
Token name or symbol — Search by token name or ticker symbol to find token contract pages with holder counts, transfer history, and supply information.

Understanding a Transaction Page

When you open a transaction on the explorer, you will see the following key fields:

Status — Whether the transaction succeeded or reverted. A green checkmark indicates success; a red indicator means the transaction failed.
Block — The block number in which the transaction was included. Click the block number to view all transactions in that block.
From / To — The sender and recipient addresses. If the recipient is a contract, you will see the contract name (if verified) and the method that was called.
Value — The amount of ETH transferred in the transaction (may be zero for contract interactions).
Gas used — The actual gas consumed by the transaction, along with the gas limit that was set and the effective gas price.
Input data — The raw calldata sent with the transaction. If the contract is verified, Blockscout will decode this into a human-readable function call with named parameters.

Tabs on the transaction page may also include internal transactions (calls between contracts), event logs emitted during execution, and token transfers triggered by the transaction.

Understanding an Address Page

An address page displays all activity associated with a particular wallet or contract:

Balance — The current ETH balance held by the address, denominated in both ETH and its approximate value.
Transactions — A chronological list of all transactions sent from or received by the address. Each entry shows the method called, value transferred, and gas fee.
Internal transactions — Calls made between contracts during transaction execution. These are not separate on-chain transactions but are important for understanding complex contract interactions.
Token transfers — All ERC-20, ERC-721, and ERC-1155 token movements involving the address, with links to the corresponding token contract pages.
Contract tab — For verified contracts, this tab displays the source code, ABI, compiler settings, and provides read/write interfaces to interact with the contract directly from the explorer.

Verifying Contracts on the Explorer

Contract verification links your deployed bytecode to its original Solidity (or Vyper) source code, making it publicly readable and enabling the explorer's read/write interface. Verified contracts display a green checkmark on their address page and allow anyone to inspect the code and interact with public functions.

You can verify contracts directly through the Blockscout UI, or programmatically using Hardhat or Foundry. For detailed instructions on all verification methods, see the Verify Smart Contracts guide.

Verify Early

We recommend verifying your contracts immediately after deployment. Verified contracts build trust with users and make debugging significantly easier since transaction input data is automatically decoded.

API Access

The Blockscout explorer exposes a REST API that allows you to programmatically query blockchain data. The API is available at:

Blockscout API Base URL

https://testnet-explorer-api.lcx.com/api/v2/

Common API endpoints include:

/addresses/:address — Retrieve address details including balance and transaction count.
/addresses/:address/transactions — List transactions for a specific address.
/transactions/:hash — Get full details for a specific transaction.
/blocks/:number — Retrieve block details by number.
/tokens/:address — Get token information including supply and holder count.
/smart-contracts/:address — Retrieve verified contract source code and ABI.

API Documentation

The full Blockscout API documentation is available through the explorer's built-in API docs page. Visit the explorer and click "API" in the navigation for interactive documentation with request/response examples.
