"Public key" for Bitcoin in Opera Crypto Wallet

Hello there!

I've been trying to link my Opera Crypto Wallet to a financial aggregator, which allows be to see an overview of my assets. Because it doesn't integrate directly with Opera, I had to add the public key of each currency (Ethereum, Polygon, etc.) and it worked.

However, for Bitcoin, because a new key is generated for every transaction in Opera, it cannot be used for tracking. I would have to find the "xpub, ypub or zpub key".

There are instructions on how to find the xpub key on that webpage below, under the section "Generating your xpub key from your recovery phrase", since Opera doesn't provide the key directly. It requires the use of this BIP39 tool.

So I provided my Opera Crypto Wallet backup phrase in the relevant field, and tried all derivation paths, but my financial aggregator never detected the key properly.

Does anyone have an idea about this?

• Thank you! -

In summary, I'm trying to find the "extended public address" for my Bitcoin vault in the Opera Crypto Wallet, which would correspond to either the xpub, ypub or zpub key. Any help would be appreciated! Thank you!

@philippechoquette Does Opera Wallet have it?

@leocg There's only one place where you can find an address for Bitcoin and it's when you go to "Receive", but it's indicated that this address changes for every transaction, so it can't be used to keep track of the vault.

@leocg See the link below for the email from the support team of Koinly. As mentioned, this would really required knowledge from an Opera staffer.

So I finally figured out how to use that tool to find the information... If anyone else is looking for it, the Opera Crypto Wallet uses the BIP49 derivation path, resulting in a ypub key.

Otherwise, pretty disappointing experience on this forum... It showcases that there is a need for Opera to have a proper support team.
