UNBANK · In development
Building the next
chapter of payments.
Umbra's non-custodial Monero gateway is live today. UNBANK is the next chapter, currently in development: a way for customers to pay with a card while merchants receive Monero in their own wallets.
Live today · Umbra on Monero mainnet
What already runs.
None of this is a slide. It's a working non-custodial gateway settling real Monero. We do not yet claim card acceptance, fiat conversion, or production-hardening. These are the next areas of development.
Non-custodial by construction
We hold a wallet view key, never a spend key. We can watch payments arrive; we cannot move them. Funds land straight in the merchant's own wallet.
A subaddress per invoice
Every invoice mints its own Monero subaddress, so payments are attributable without ever reusing an address.
Fiat-priced, rate locked
Invoice in USD or EUR with the XMR rate fetched live and frozen at creation, or price natively in XMR.
Two signed webhooks
payment_detected at 0-conf, payment_confirmed at 10, each HMAC-SHA256 signed, with retry, one-click redelivery and secret rotation.
Reorg-safe
Dropped transactions and chain reorganizations revert cleanly; a detected invoice falls back to pending and its webhook is withdrawn.
Live on Monero mainnet
Running today against a real mainnet node and wallet RPC, not a testnet demo.
In development
What we're building.
The airlock: buyer pays Visa, merchant receives Monero to keys we never hold, our custody designed to be brief. Monero settlement already runs; card acceptance and conversion are in development.
Licenses & registrations
The registrations in each jurisdiction that keep the door open, the reason unlicensed attempts get welded shut.
An acquiring partnership
The card-in leg: a licensed acquirer so buyers can pay with the card already in their pocket.
Fiat → XMR conversion
Regulated desks, under our name, so the paperwork never learns the merchant's.
The Shopify listing + first 10 merchants
The distribution and the first lawful merchants done confessing.

Lawful merchants only, privacy for businesses, not impunity for crime. The airlock (card-in, fiat conversion) is in development; only the non-custodial XMR leg is live today. Nothing here is investment advice.
