USDC on Solana · no paperwork
Zero paperwork.
Real cards.
Virtual cards, gift cards and mobile data, paid in USDC on Solana. Connect a wallet and spend - no ID scans, no selfies, no waiting room. Your agents can shop too, inside the limits you set.
N°01 / Cards
Two cards.
Pick your rhythm.
One card you keep and top up, or one you load once and spend down. Both are virtual, both are paid for in USDC, and you see the full price before anything is charged.
Both cards live in your account, not in your name. Add funds in USDC, spend anywhere the network is accepted, and reveal the number only when you need it.
Reloadable Mastercard
For subscriptions and anything that renews.
- 0Top up in USDC whenever you like

Illustrative numbers. The app shows the live total, line by line, before you confirm. Networks may ask for cardholder billing details - never for documents.
N°02 / Gift cards
Gift cards,
sorted by country.
Choose a country, then a brand, then one of the amounts that brand actually sells. The code waits in your account until you decide to reveal it - not in an inbox.
EUR 25 ≈ 27.32 USDC
Availability is checked when you ask for a quote. Brand and country rules apply.
N°03 / Mobile data
Data before
the plane lands.
eSIM data for one country, a whole region or the entire map. Need a number? Get one for calls and texts, or just for a single verification code.
Example prices. Carrier activation rules depend on the plan.
N°04 / Agents
Give your agent
a wallet with a leash.
Create a key for an AI agent, decide what it may buy and how much, and keep the final word. It spends from your balance - it can never withdraw it.
You set the rules once.

- 0Caps per order, per day and in total

N°06 / Wallet & privacy
Keep less.
Expose less.
Pay straight from your own wallet when you don’t need a card, and keep what you hold to yourself when you do.
From your wallet
Send USDC. Pay per request.
Transfer to any Solana address or pay pay-per-request APIs directly. You sign every payment yourself; nothing sits in a Nulo balance on the way. These payments are public on-chain, like any Solana transfer.

N°08 / FAQ
Straight answers.
Do I need to verify my identity?
No. You connect a Solana wallet and fund with USDC. Card networks may ask for cardholder billing details, but never for documents or selfies.
What does it cost?
Every quote shows the provider price and the Nulo fee as separate lines before you pay. Card issuance prices are listed in the app.
Is there a spending limit?
We don’t put a monthly cap on reloadable cards. Merchants, issuers and countries can still have rules of their own.
Can an agent drain my balance?
No. An agent key can only buy within the scope and limits you set, and it can never withdraw.
How do I get gift card codes?
They stay hidden in your account until you reveal them, so they’re never sitting in an email.
Which wallets work?
Any Solana wallet that can hold USDC and sign transactions.
