Some chains can't be read at all

Paste a Bitcoin or Ethereum address anywhere and you can see what it holds. Nobody built that as a feature. It's how those chains work: every balance is public, permanently, to everyone.

Monero and Zcash are built the other way.

On Monero, amounts and addresses are hidden by default. There's no public balance to look up. Zcash gives you a choice — a transparent address works like Bitcoin's, a shielded one doesn't.

Reading a shielded balance needs the account's private viewing key. That's a key. It belongs to whoever owns the account, and handing it to a product hands over the ability to watch everything that account does, forever.

Aureus doesn't accept keys of any kind, so we can't read those chains and we won't build a way to.

This is the one place where “we can't show you that” isn't us being careful or unfinished. Nobody can show you that from an address alone. Anything claiming otherwise has either asked someone for a viewing key, or is showing you something else.

So when a read here names Monero or Zcash as unreadable, that's not a hole in our coverage. It's the chain doing exactly what it was designed to do.
