🔬 Spark Lightning Address Doxxer: a simple tool to decode Spark addresses from any Lightning address or invoice. https://reneaaron.github.io/spark-lnaddress-doxxer/ Does somebody understand why WoS addresses seem to encode the spark pubkey as a routehint, but other providers such as blitz wallet do not? h/t @Carman

I asked @c93406ed…6918f4a1 about this and he said that @9711d1ab…863ebd81 SDK also doesn’t expose the Spark public key. So there doesn’t seem to be any reason for it.

I also don't expose it on my spark wallet, could it be so that other WoS users can see that it's Spark to Spark and use Spark tx instead?

What's the impact of exposing the spark address? Is it like a reused on chain address so you can see all transactions or something?

Wow. Just tested with my @be1d8979…37fe9479 readable receiving address and it was able to extract my full transaction history. Testing the invoices and/or readable receiving addresses from @ecbe3721…13ed8ea1 and @c9bdb692…234e27a4 both did not reveal that data. Until this changes I will stop using Wallet of Satoshi. It's a shame, I really like the app.

This doesn't just work for any lightning address, only ones that are using spark internally. (and also seemingly not all of them, no idea why yet)

It's a config option when creating an invoice, WoS could turn it off if they wanted to

Are there any non-obvious reasons not to turn it off?

Saves on fees for spark to spark transfers

Because they can directly settle internally between WoS users without touching lightning at all?
