Adding funds

How do I add funds?
Cryptocurrency today. Card, Apple Pay and Google Pay are coming soon.
Which coins can I send?
Each one gets you a permanent address that is yours — send to it as many times as you like.
  • Tether (USDT, TRC-20)
  • Tether (USDT, BEP-20 / BSC)
  • Tether (USDT, TON)
  • Tether (USDT, ERC-20)
  • USD Coin (USDC, ERC-20)
  • Bitcoin (BTC)
  • Ethereum (ETH)
  • Litecoin (LTC)
  • Solana (SOL)
  • Binance Coin (BNB, BSC)
  • USD Coin (USDC, Solana)
  • TRON (TRX)
  • Cardano (ADA, BEP-20 / BSC)
  • Dogecoin (DOGE)
  • Bitcoin Cash (BCH)
  • Toncoin (TON)
What is the smallest deposit?
The minimum depends on the coin and network and can change. Open your deposit screen to check the current minimum before sending. Deposits below it may not be credited. The amounts below are recommendations for keeping send fees reasonable, not processing minimums:
NetworkWorth sending at least
Tether (USDT, TRC-20)$20
Tether (USDT, BEP-20 / BSC)$5
Tether (USDT, TON)$5
Tether (USDT, ERC-20)$30
USD Coin (USDC, ERC-20)$30
Bitcoin (BTC)$15
Ethereum (ETH)$30
Litecoin (LTC)$5
Solana (SOL)$5
Binance Coin (BNB, BSC)$5
USD Coin (USDC, Solana)$5
TRON (TRX)$5
Cardano (ADA, BEP-20 / BSC)$5
Dogecoin (DOGE)$5
Bitcoin Cash (BCH)$5
Toncoin (TON)$5

Sending on the wrong chain for the amount is the single most common way people lose money here, so pick a cheap network for small deposits.

Do you charge a deposit fee?
No. You pay the network's fee to send, and we credit what arrives. We take nothing on top.
How long does a deposit take?
Seconds to a few minutes on most coins. Bitcoin and Ethereum can take longer when their networks are busy.

Cashing out

What is the smallest withdrawal?
$10.00.
Which currencies can I withdraw to?
USDT on the Tron network (TRC-20). More networks are being added.
  • USDT (Tron / TRC-20)
What does a withdrawal cost?
Just the network fee, passed straight through. We add nothing on top.
How long does it take?
Usually minutes. Larger withdrawals get a quick manual approval first, usually a few minutes to a few hours.
What's unplayed?
Money you deposit starts as Unplayed: it has to be opened on packs once before it can leave — a $50 deposit is withdrawable after $50 of opens. Your wallet shows two figures, Withdrawable and Unplayed, and every paid open moves money from one to the other. Selling a win from a free pack (promo code, waitlist reward, daily pack) adds to Unplayed too. This is what keeps Kruna a game rather than an exchange.

Items & shipping

What happens when I win something?
It lands in your inventory and it is yours. Sell it back instantly for balance, or keep it and have the real thing shipped to you.
Do you ship the actual item?
Yes, to a growing list of countries, and we cover the shipping on anything worth over $100. If we do not reach you yet, you can still sell any item back instantly — more countries are being added.

Fairness & odds

How do I know the odds are real?
Every open is decided by two numbers: a secret one we commit to before you click, and one you choose and can change any time. Neither side can steer the result alone, and we cannot change ours after the fact without breaking the seal you already saw.

The three numbers behind every open:

Our sealed number

Shown as a fingerprint before you open

…

Your number

Yours to set, change it whenever

The result

Both numbers mixed, landing between 0 and 1

0.418293…

The mixHMAC-SHA256(server, client:nonce)[0..8] / 0xFFFFFFFF → 0–1

Rotate your seeds in your profile and we hand over the raw secret number. You can then redo the mix for every open you made with it and confirm each result matches the seal you were shown beforehand.

Where do I see an item's chance?
On the pack page, next to every item. The chance is set per pack rather than per item, because the same item can sit in several packs at different prices — a watch that is a long shot in a cheap pack is a realistic pull in an expensive one.
Can you change what I win after I click open?
No. The result is fixed the moment the two numbers meet, and our half was sealed before you clicked. Changing it afterwards would break the fingerprint you can already see.

The United States, the United Kingdom, Serbia and Switzerland, along with some other countries where we cannot operate yet.
