About Arbiscan

Arbiscan is the main block explorer for reading activity on Arbitrum, including Arbitrum transactions, wallet addresses, contract pages, token transfers, event logs, internal transactions, gas usage, and bridge-related movements. It is useful when you need to paste a transaction hash, address, token contract, block number, or verified contract name and understand what actually happened on an Arbitrum L2 network. Users can check whether a transaction succeeded or reverted, which contracts were called, what tokens moved, which approvals are active, how L2 gas and fees were charged, and whether a contract source is verified before interacting with it. For a complete Arbiscan guide workflow, compare suspicious or high-value activity against Etherscan, Optimistic Etherscan, official protocol documentation, bridge records, and known contract addresses.

What is Arbiscan?

Arbiscan is a blockchain explorer for the Arbitrum ecosystem. It lets users search transaction hashes, wallet addresses, contract addresses, token contracts, blocks, logs, internal transactions, and bridge-related activity so they can understand what happened on an Arbitrum L2 network. A practical Arbiscan guide usually starts with a transaction or address lookup, then checks token transfers, gas and fee details, contract calls, verified source code, approvals, labels, and logs. For higher-value activity, Arbiscan data should be compared with Etherscan, Optimistic Etherscan, official bridge records, and protocol documentation.

How to Use Arbiscan

Open Arbiscan and search for a transaction hash, wallet address, contract address, token address, block number, or readable contract label.

On a transaction page, check the status, block confirmation, from and to addresses, method name, value, token transfers, L2 gas used, fee paid, logs, and internal transactions.

On an address page, review ETH balance, token holdings, token transfers, NFT transfers, contract interactions, and token approvals before treating the wallet or contract as safe.

On a contract page, confirm whether the contract is verified, read the source code and ABI when available, inspect read/write contract tabs carefully, and compare the address with official protocol documentation.

For bridge, DeFi, or high-value activity, cross-check Arbiscan with Etherscan, Optimistic Etherscan, official bridge records, protocol dashboards, and known token contract lists.

Arbiscan's Core Features

Transaction lookup for Arbitrum hashes, including success or revert status, block number, timestamp, sender, receiver, method, value, token transfers, gas used, effective fees, logs, and internal calls.

Address lookup for wallets and contracts, including balances, historical transactions, ERC-20 and NFT transfers, contract interactions, labels, and approval exposure.

Verified contract inspection, including source code, compiler details, ABI access, read contract functions, write contract interfaces, creation transactions, and related contract events.

L2 activity review for Arbitrum-specific behavior such as lower execution fees, sequencer-confirmed activity, bridge deposits and withdrawals, and interactions that may also have a related Ethereum L1 record.

Explorer comparison workflows that use Arbiscan alongside Etherscan for Ethereum mainnet activity and Optimistic Etherscan for Optimism activity when investigating multichain protocols, bridges, tokens, or suspicious addresses.

Arbiscan's Use Cases

Check a transaction hash after using a wallet, DEX, bridge, lending market, NFT marketplace, or protocol on Arbitrum.

Inspect an address before trusting a counterparty, treasury wallet, contract deployer, airdrop claim page, token holder list, or protocol-controlled account.

Read a verified contract before interacting with a token, vault, bridge adapter, proxy, staking contract, governance module, or unfamiliar DeFi integration.

Review token approvals and transfer history before revoking permissions, signing a new approval, debugging missing funds, or investigating a fake token.

Compare Arbiscan, Etherscan, and Optimistic Etherscan when a bridge transfer, multichain token, or protocol action spans Arbitrum, Ethereum, and Optimism.

Frequently Asked Questions About Arbiscan

Arbiscan: What can users inspect with it?

Users can inspect Arbitrum transaction hashes, wallet addresses, contract addresses, blocks, token transfers, NFT transfers, approvals, logs, internal transactions, gas usage, and bridge-related activity. It is most useful when you already have a hash, address, token, or protocol event to investigate.

Arbiscan: How should transaction status be verified?

Open the transaction hash on Arbiscan and check the status, block confirmation, method, from and to addresses, value, token transfers, gas details, logs, and internal transactions. For bridge or multichain actions, compare the result with the related Etherscan or Optimistic Etherscan record and the protocol's official documentation.

Arbiscan: What explorer data can be misleading?

Common mistakes include checking the wrong chain, trusting a copied token name instead of the contract address, missing internal transactions, ignoring event logs, confusing approval transactions with transfers, and assuming a verified contract is automatically safe. Labels and indexing can also lag or be incomplete.

Arbiscan: Which explorers should be cross-checked?

Use Etherscan for Ethereum mainnet records, Optimistic Etherscan for Optimism records, and official bridge or protocol dashboards when the same wallet, token, bridge, or contract system spans multiple chains. This is especially important for deposits, withdrawals, wrapped tokens, and cross-chain protocol actions.
