Is this a valid bitcoin address?
327 sats \ 12 comments \ @spiderman 25 Jul bitcoin

I was signing up for a conference that accepts payment in bitcoin. I chose the option and the following address showed up.

34caqaP9TBbZSqL3EsVNHf1zyrp8gEew1e

It looks weird, as all my trezor addresses start with bc1. Is it a legitimate address? I skipped payment because thought if I pay, the funds will be gone.

Though not good for privacy you could just look it up on mempool.space https://mempool.space/address/34caqaP9TBbZSqL3EsVNHf1zyrp8gEew1e

if its an invalid address it will show it as invalid

Yes.

This will explain it better than I can.

"How to identify a bitcoin address? You can identify the type of a bitcoin address by looking at the first letters of it. If it starts with "1", it's a legacy address which are the most expensive fee wise. If it starts with "3", it's a P2SH address. If it starts with "bc1q", it's a native segwit and if the first 4 letters are "bc1p", it's a taproot address."

Different wallet type. I tried it in blue wallet, and it seems to be valid because it took me to the confirmation page when I plugged in an amount. If I change the last character to something else, it doesn’t let me proceed because it’s invalid

Good call on being cautious. That looks like a legacy address easy to second guess when you are used to bc1. 😅

Look up "wrapped segwit."

What OP stated wasnt wrapped SegWit address but old Script Hash address

Pay-to-Witness-Script-Hash (P2WSH) is the segwit variant of P2SH. The main advantage to using P2WSH over P2SH is that it can help lower transaction fees, and the primary reason to use a script hash instead of a public key hash is to accommodate multisig arrangements.
Like P2WPKH, a P2WSH address begins with a prefix of bc1q. However, it has a longer character length of exactly 62. Unlike the address types covered thus far, P2WSH addresses are created using the SHA-256 hashing function alone, without including RIPEMD-160, resulting in the increased character length. This was implemented cautiously, adding extra protection from a fairly nuanced and extremely unlikely multisig attack vector.

Has prefix "bc1q"

Pay-to-Script-Hash (P2SH) was introduced to bitcoin as a soft fork in accordance with BIP 16 on April 1, 2012. Like most forks, the story behind it is fascinating. P2SH shares a lot in common with P2PKH. The main difference is that the address is created by hashing a redeem script instead of hashing a single public key.
A redeem script can be thought of as coded instructions specifying how bitcoin received to the P2SH address can be spent in the future. There could be a wide range of possibilities, including multiple different public keys. The receiver, not the sender, determines the script details, and the spending instructions are not exposed publicly until bitcoin is spent out of the address.
While advanced users can construct complex scripts, the most common uses for P2SH have been to create nested segwit addresses (covered below) and multisig wallets. For example, a script can include three public keys and specify that signatures from any two of the corresponding private keys can spend the bitcoin. This would create a 2-of-3 multisig address.
P2SH addresses are exactly 34 characters in length, and they begin with a prefix of 3, as specified by BIP 13. Before the soft fork on April 1st, a handful of transactions experimented with this alternative prefix, the first of which is found in Block 170,052.

Has prefix "3", which is (again) what op stated in above post

Nested segwit (also known as wrapped segwit)
Therefore, the P2SH addresses using this trick became known as nested segwit

What am I missing?

  • Script Hash : Spending with extra spending condition (most-known method is multisig).
  • Segwit : Regular spending address with discounted size.
  • Segwit Script Hash : same as Segwit but it can carry certain spending rules while also receiving segwit discount
  • Nested Segwit : SegWit script inside of Pay-to-Script Hash. Popularly known as a temporary solution before SegWit gained adoption because it allow old address to being able to interact with new standard.

Doesnt nested segwit start with 3?

Nested SegWit is one example of Script that P2SH address can carry hence i said

What OP stated wasnt wrapped SegWit address but old Script Hash address

If u still have doubt in mind look up https://mempool.space and paste the address there, mempool.space will show the address type as "P2SH"

It's still an empty address atm, the spending condition will be revealed after it has been used to conduct outgoing transaction
