What address types does this validator support?

All four Bitcoin address types: Legacy P2PKH (starting with 1), Nested SegWit P2SH (starting with 3), Native SegWit Bech32 (bc1q...), and Taproot Bech32m (bc1p...).

What's the difference between Bech32 and Bech32m?

Bech32 is used for Native SegWit (bc1q). Bech32m is a strengthened variant with a different checksum constant — used for Taproot (bc1p) and other version 1+ witness outputs. We verify both.

Does this tool check the balance or activity of an address?

No. It only validates the address format and checksum. Checking balance requires querying the blockchain, which needs a network call — this tool is 100% offline.

Why does my address show as 'testnet'?

Testnet addresses start with m, n, 2, or tb1. They're valid addresses but only work on Bitcoin's test network, not mainnet. Sending mainnet funds to a testnet address will lose them.

Can this tool detect which wallet generated an address?

No. Wallet identity isn't encoded in addresses. We can only tell the address type (Legacy/SegWit/etc.) and the network (mainnet/testnet).

Is my address sent anywhere?

Never. The Base58Check and Bech32 verification are computed locally in JavaScript. Verify with DevTools → Network — zero requests.

How to use Bitcoin Address Validator

Follow these steps — everything happens instantly in your browser.

1
Step 1. Paste a Bitcoin address into the input field.
2
Step 2. The validator instantly detects the address type (Legacy, SegWit, Native SegWit, Taproot) and runs checksum verification.
3
Step 3. Read the green/red status — green means the checksum passes, red means the address is invalid.
4
Step 4. Use the info card to learn which networks and wallets support that address type.
