About this app
WHAT IT DOES
Base Network Explorer is a read-only blockchain lookup tool for the Base network. It lets you inspect any address, transaction, or block by simply pasting an identifier. For an address, it shows native ETH balance, contract bytecode (with a contract/non-contract indicator), and balance snapshots for common ERC-20 tokens such as WETH, USDC, DAI, cbETH, and USDbC. For a transaction, it displays sender, recipient, value, gas price, and block number. For a block, it returns the block hash, timestamp, gas used and limit, and a sample of transaction hashes. The tool supports both Base Mainnet and Base Sepolia.
HOW TO USE
Connect your wallet using the Connect button — this establishes the RPC connection through the injected wallet bridge. Select your network from the dropdown (Base Mainnet or Base Sepolia). Enter an Ethereum-style address (0x...), a transaction hash (0x...), or a numeric block number into the lookup field, then click Look up or press Enter. Results appear immediately in the card below. Each result includes a direct link to BaseScan for deeper inspection.
TECHNICAL MECHANISM
The tool uses ethers.js v5.7.2 over the wallet's injected provider. For ERC-20 balance checks, it calls balanceOf on a curated set of common Base tokens — not an exhaustive scan, because scanning all token transfers would require an archive node and enormous log ranges. The token list is small and targeted so the lookup stays fast (under 2 seconds on most connections). Address validation uses ethers.utils.getAddress to normalize checksums. The provider is obtained through BGWallet.getProvider() and is never cached beyond the current session — storage is unavailable in the sandboxed frame, so all state is ephemeral.
WHAT IT CANNOT SEE
This tool does not read pending mempool transactions — it only queries finalized state. It cannot show internal transactions, event logs, or historical token balances at arbitrary past blocks. It does not decode custom contract calls or proxy patterns. ERC-20 detection is limited to a fixed list of major Base tokens; it does not auto-discover all tokens held by an address. It cannot fetch private transaction data or state beyond what the RPC provides. It does not support cross-chain lookups — only the selected Base network.
PLEASE NOTE
This is an EVM-only tool designed for the Base network. It does not support Solana, Tron, Bitcoin, or any non-EVM chain. All lookups are read-only — no transaction signing or submission occurs. The tool runs entirely in your browser; no data is sent to any backend server.
