FAQ

Common questions

No, only public address if you choose to connect a wallet; our assessment works with just the questions above.

It helps you calculate obligations; always consult a tax professional. We follow published IRD cryptoasset guidance, including the Budget 2026 updates and the extra $15 million compliance programme, but we are not the IRD and we do not file returns for you.

Ledger, Trezor, Coldcard, BitBox, Keystone.

Yes, encrypted and never sold. We only collect what we need to produce your report, and we never ask for private keys or exchange passwords.

Free assessment; Pro plans from $49 NZD/year.
