Article IV
Manifestos don't settle. Rails do.
Here is where declaring turns into a build plan, and where we're honest about what runs today versus what is in development.
Your customers will not install a wallet. Not this year, not for a decade. They pay with the cards in their pockets, and any privacy movement that requires them to change first is a movement that loses. So we take the transaction as the world makes it, card-shaped, surveilled on the buyer's end as it already was, and we change where it lands.
The design: buyer pays Visa, merchant receives Monero, at a subaddress derived from keys we never hold. The confession ends at the point of sale.
And the airlock has two doors. The same rail lets people, not only merchants, fund privately, carry a card that spends anywhere, and cash Monero back out to a bank. Merchants get paid in XMR today; the consumer side is on the roadmap, in development. See the card →
The rail in development · not yet live
T+0s
The world's rail. Card authorization through a licensed acquirer. This leg was never private and we don't pretend otherwise.
FIAT
T+0d
The buffer. Rolling reserve against chargebacks, the reversible-in, irreversible-out asymmetry is real, and it will die on our books, not yours.
RESERVE
T+1d
The conversion. Fiat to XMR through regulated desks, under our registrations, on our name. We absorb the paperwork so it never learns yours.
FX
T+2d
The exit. Settlement lands in your wallet, your keys, a fresh subaddress. Our custody of your value: forty-eight hours, then zero, forever. This last leg, Umbra, already runs.
XMR
Exhibit B · what already runs, Umbra, on Monero mainnet
Non-custodial view-only wallets: we hold a view key, never a spend key, we cannot move your funds. A fresh subaddress per invoice. USD/EUR pricing with the rate locked at creation. Two HMAC-signed webhooks, payment_detected at 0-conf, payment_confirmed at 10, with retry, redelivery and secret rotation. Dropped-transaction and reorg reversion. Running against a real Monero mainnet node today.
Not yet, and not claimed: card acceptance, fiat conversion, and production-hardening. Those capabilities are in development.
