Fyer
Arriving in Korea
Bring stablecoins.
Spend won.
Korea runs on won, and the card in your pocket may not clear here. Fyer turns the stablecoins you already hold into won-priced tourism vouchers — spent by showing a code at the counter.

The mid-market rate, read from the same oracle the app uses. A 0.30% conversion fee applies at purchase and is shown before you confirm — never after.
Why travellers use it
Money that works the moment you land
No branch visit, no waiting for a transfer to clear, no explaining yourself at a counter.
One balance, in won
FYUSD, USDT, USDC and DAI all read as a single won figure. Nothing to convert by hand, no rate to watch while you shop.
Priced before you agree
The rate, the fee and the final won amount are on screen before you confirm. What you sign is what comes off your balance.
Change stays yours
Spend part of a voucher and the rest waits for next time. Leftover balance can be sent back to your wallet.
In the app
Won on the front screen
Whatever you deposited, the number you look at is the number you can spend. The rate beside it is the live one — the same figure this page is showing you.
- Deposit, vouchers and history one tap from the balance
- Tap the eye to hide the number at a counter
- Open “What's inside” to see which coins make up the total
How it works
Three steps, in this order
You verify before you fund, and you fund before you spend. Each step has to finish before the next one opens.
Verify once
Scan your passport photo page, hold it to the phone to read the chip, then a selfie. About a minute. Korean regulation requires it before any money moves.
Send stablecoins
From a wallet you already use. Send from the address you registered — that is how we know the deposit is yours.
Spend in won
Your balance reads in won from that moment. Show the code at the counter and the amount comes off.
Before you land
What you don't need
The usual ways to spend foreign money in Korea all ask for something a visitor doesn't have.
- A Korean bank account
- A card that clears in Korea
- An exchange listing in your country
- Cash you have to carry home
Where it spends
The things a trip is made of
Vouchers are issued against Korean tourism partners and priced in won. You pick the category; the app shows what is in stock.
