Bitcoin / block
Bitcoin block lookup
Look up any Bitcoin block on mempool.space. tx.taxi detects the format, picks the right Bitcoin explorer, and redirects.
Bitcoin is the original UTXO chain, and its addresses and transaction hashes look nothing like an EVM 0x value. tx.taxi's configured primary Bitcoin explorer is mempool.space, widely used for mempool inspection, fee estimates, and confirmation tracking. Paste a BTC address (legacy 1..., script 3..., or bech32 bc1...), a 64-character hex transaction ID, a block hash, or a block height at tx.taxi/{value} and the router classifies the format, picks mempool.space, and 302-redirects you to the matching /address/, /tx/, or /block/ page. The same JSON pipeline at /api/v1/resolve lets wallets and bots reuse the classifier. On this page: Bitcoin block lookups specifically.
How it works
- Copy your
Bitcoin block(e.g. a block height or hash). - Paste into the search above or visit
tx.taxi/<your-block>directly. - tx.taxi detects the Bitcoin format and redirects to mempool.space.

Frequently asked questions
What does a Bitcoin address look like?
Bitcoin has three common formats: legacy addresses starting with 1, P2SH addresses starting with 3, and bech32 SegWit addresses starting with bc1. Taproot addresses also use bech32m and start with bc1p. tx.taxi recognises all of them.
How long is a Bitcoin transaction ID?
A Bitcoin txid is a 64-character lowercase hex string, no 0x prefix. It is the double-SHA256 hash of the serialized transaction. Paste one at tx.taxi and you'll be routed to mempool.space's /tx/ page.
Can I look up a Bitcoin block by height on tx.taxi?
Yes. Paste a plain integer like 800000 at tx.taxi/800000 and the router treats it as a block height. mempool.space serves the matching block page.
