Bitcoin address inspector

Validate a Bitcoin address, identify its network and script type, and inspect the scriptPubKey without querying a block explorer.

No blockchain lookup. The address is processed only to decode its format and is not stored. Avoid reusing addresses when privacy matters.

What this Bitcoin address checker shows

Bitcoin addresses encode a destination script and a network. This tool recognizes legacy P2PKH, P2SH, native SegWit, and Taproot formats. It also produces the scriptPubKey used in a transaction output.

Why network validation matters

Mainnet, testnet, signet, and regtest use different address encodings. An address can be structurally valid but inappropriate for the network where you intend to transact.
