Optimism / address
Optimism address lookup
Look up any Optimism address on Optimistic Etherscan. tx.taxi detects the format, picks the right Optimism explorer, and redirects.
Optimism (OP Mainnet) is an Ethereum L2 optimistic rollup and the original OP Stack chain. It uses standard EVM address and hash formats. tx.taxi's configured primary Optimism explorer is Optimistic Etherscan, the Etherscan-team instance for OP Mainnet, with contract verification, L2 receipts, and bridge tracking. Paste an Optimism address, transaction hash, block hash, or block number at tx.taxi/{value} and the router classifies the value and 302-redirects to the matching /address/, /tx/, or /block/ page. Because Optimism shares the EVM format with Ethereum, the same string can be valid on both chains. On this page: Optimism address lookups specifically.
How it works
- Copy your
Optimism address(e.g. a wallet address). - Paste into the search above or visit
tx.taxi/<your-address>directly. - tx.taxi detects the Optimism format and redirects to Optimistic Etherscan.

Frequently asked questions
What does an Optimism address look like?
Optimism uses the EVM format: '0x' followed by 40 hex characters. It is the same format as Ethereum, Base, and other EVM chains, so the same string can be valid on multiple chains.
How is Optimism related to Base?
Base is built on the OP Stack, the same software stack that powers Optimism (OP Mainnet). They are separate chains with separate explorers, but the on-chain formats and many concepts are shared.
Does Optimistic Etherscan show L1 batches?
Optimistic Etherscan presents L2 transactions and references the L1 batch they were submitted in, since Optimism is an optimistic rollup that posts data and proofs to Ethereum.
