Create a member account in clear steps.

First create one soulbound Membership SBT for the connected wallet, then choose a residence H3 cell from a map. KYC or World ID is optional during signup and can be added from the member area whenever you are ready.

First-time wallet

Backend routing should show this flow only when the connected address has no active Membership SBT. Registered wallets should land on /member.

Step 2

Choose your residence H3 cell from a map.

Required

Users should not need to type an H3 cell. Let them search an address or place, use current location, then confirm the map cell Sonari will register.

Search city, station, or address

Search text may be sent to a map provider. Sonari stores the selected H3 cell only.
