Bitcoin Address Validator
Private by design — runs entirely in your browser
Detect whether a Bitcoin address is P2PKH, P2SH, P2WPKH (SegWit), Taproot or testnet, with explicit reasons for unrecognised inputs.
Which address types are recognised
Legacy P2PKH (1…), P2SH (3…), native SegWit P2WPKH/P2WSH (bc1q…), Taproot (bc1p…) and testnet (tb1…, m/n/2…). Prefix and length rules follow current Bitcoin Core conventions.
Does the tool check the checksum bytes
No — only the structural pattern. Full base58 or bech32 checksum verification is on the roadmap. The current check catches typos that change the address type.
What does mainnet vs testnet mean
Mainnet is the production Bitcoin network where real BTC moves. Testnet (and signet) is for development; its addresses cannot send or receive on mainnet.
