Arbitrum One / address
Arbitrum One address lookup
Look up any Arbitrum One address on Arbiscan. tx.taxi detects the format, picks the right Arbitrum One explorer, and redirects.
Arbitrum One is an Ethereum L2 optimistic rollup that uses the EVM address and hash formats. tx.taxi's configured primary Arbitrum explorer is Arbiscan, widely used for L2 transaction receipts, contract verification, and L1-to-L2 message tracking. Paste an Arbitrum address, transaction hash, block hash, or block number at tx.taxi/{value} and the router classifies the format and 302-redirects to /address/, /tx/, or /block/ on Arbiscan. Arbitrum has its own L2 block numbering separate from Ethereum L1, which Arbiscan presents alongside the matching L1 batch reference. On this page: Arbitrum One address lookups specifically.

Frequently asked questions
Does Arbitrum One have its own address format?
No. Arbitrum One uses the EVM format: '0x' followed by 40 hex characters. The same string can also be valid on Ethereum and other EVM chains, so chain context matters.
Are Arbitrum block numbers the same as Ethereum block numbers?
No. Arbitrum One has its own L2 block numbering that is independent of Ethereum L1. Arbiscan shows the L2 block plus a reference to the L1 batch the transactions settle to.
What is the difference between Arbitrum One and Arbitrum Nova?
Arbitrum One is the main rollup with full Ethereum security. Arbitrum Nova uses a data-availability committee and targets cheaper transactions. They are separate chains with separate explorer instances.
