Check Bitcoin SegWit Address Tool

Wanna distinguish between SegWit and legacy/normal bitcoin wallet address?

This online tool can help you check if a BTC address is legacy or SegWit (P2PKH, P2SH, P2WPKH, P2WSH, P2SH-P2WPKH, P2SH-P2WSH) on the mainnet.

You need only a browser and a valid bitcoin address.

Be safe with this tool; we use only public data and there is no need for login, password or private key!

SegWit (native-P2WPKH)

This address is a SegWit address.

SegWit (native-P2WSH)

This address is a SegWit address.

SegWit (P2SH-P2WPKH)

This address is a SegWit P2WPKH address nested in a BIP16 P2SH output, so-called P2SH-P2WPKH.

SegWit (P2SH-P2WSH)

This address is a SegWit P2WSH address nested in a BIP16 P2SH output, so-called P2SH-P2WSH.

Undecidable

This is a P2SH address, but it is undecidable if this is a SegWit or non-SegWit address.

A P2SH-P2WPKH/P2WSH address is indistinguishable from a non-SegWit P2SH address (such as a non-SegWit multi-signature address) until an UTXO is spent and the redeemScript is exposed.

To decide this, you need to send some satoshis to this address and send them to another address.

non-SegWit (P2PKH)

This is a non-SegWit legacy address.

non-SegWit (P2SH)

This is not a SegWit address, but one of other legacy P2SH addresses.

Based on the transaction history of this address, this P2SH address is different from P2SH-P2WPKH/P2WSH addresses.

What is SegWit?  What are the benefits?

Segregated Witness, also known as SegWit is a new protocol on the bitcoin network (BIP 141) effective from August 2017.

Using SegWit, you can receive significant discounts for blockchain fees on every transaction that spends funds received to a SegWit address.
