How it works
Spend your bitcoin's value
without selling it.
Four steps, no jargon. You keep your bitcoin the whole time. Here is exactly what happens, what it costs, and what we do if the price drops.
The four steps
1
You deposit bitcoin
Send bitcoin into collaborative custody, a vault that needs your key to move.
You see your bitcoin sitting safely, and the dollar credit line it unlocks. We cannot touch it, sell it, or lend it out.
2
You get a dollar credit line
Instantly. No credit check, no income proof, no waiting. Your bitcoin is the only qualification.
A line of up to half your bitcoin's value, ready to spend. Borrow as much or as little of it as you want.
3
You spend, anywhere
Tap your Iron Visa card in any shop, or send the dollars (USDT) to your own wallet or bank.
Normal card spending. The shop sees dollars. Your bitcoin never moved, so there is no sale and no tax event.
4
You repay, on your terms
Pay back whenever you like, instant and low-fee over Lightning. There is no fixed due date and no penalty for paying early.
Your balance drops, interest stops on what you repay, and the moment you are clear you can pull your full bitcoin back out, upside intact.
A real example
Illustrative numbers at a bitcoin price of about $100,000. Your real line and rate are shown live before you borrow a cent.
What if bitcoin drops?
The honest answer most lenders bury. Because you only borrow up to half your bitcoin's value, the price would have to fall more than 40% before anything happens, and we warn you at every step long before it does. You are always in control.
We warn you first
Email, text, and in-app, with the exact amount to top up. No silent surprises.
We never rehypothecate
Your coins are never lent out or reused. The exact thing that killed Celsius and BlockFi, we do not do.
What it costs, in plain language
No annual fee
Holding the card costs nothing.
From ~6% to ~16% a year
Interest by grade, around 10% typical, charged only on what you actually borrow. Borrow $1,000 for a month at 10%, pay roughly $8.
No credit check
We never pull your credit or ask for payslips.
No exit penalty
Repay early, leave anytime, take your bitcoin and go.
