News and notices

Today we are opening the public beta of Croleo. Prices, order books and trades come from our exchange engine, and orders you place match against other orders on the book. Every balance is a test fund: sign up and use Get test funds to try trading.

What you can try

• Spot markets quoted in USDT and USDC.
• Limit and market orders, including market buys by amount, with each market's fees applied.
• The withdrawal flow, including the step-up passkey check and new-address cooling period.

Tell us what is confusing or missing. Every message to support is read by the team building the product.

Croleo is a global exchange. When we launch, customers can sign up from any country except those under comprehensive sanctions: Cuba, Iran, North Korea and Syria, and the Crimea, Donetsk and Luhansk regions of Ukraine.

Croleo is not yet licensed or registered as a virtual asset service provider in any jurisdiction. Availability of each service depends on local rules, and we will publish each licence or registration once it is granted.

How the country check works

When you sign up, we ask for your country of residence and check your address during identity verification. Anyone in a sanctioned country or region is told we cannot open an account for them.

• Regulatory status
• Countries we cannot serve

Croleo accounts have no password. You can sign in with an email or SMS code, Google, Apple or a passkey, and you approve every withdrawal with a passkey: a key pair stored on your phone, laptop or security key and unlocked with your fingerprint, face or device PIN.

Why not passwords or SMS alone?

• Passwords leak in data breaches and get reused across sites.
• SMS codes can be intercepted when someone takes over your phone number with a SIM swap, so a code alone can never move funds.
• Both can be typed into a convincing fake site. A passkey only works on our real domain.

We recommend adding at least two passkeys, for example your phone and a laptop, so losing one device does not lock you out.

• Account protection
• Set up a passkey

Every listed asset trades against USDT. The largest assets also trade against USDC.

USDT markets

BTC/USDT, ETH/USDT, SOL/USDT, XRP/USDT, ADA/USDT, DOGE/USDT, TRX/USDT, AVAX/USDT, LINK/USDT, DOT/USDT, LTC/USDT, TON/USDT

USDC markets

BTC/USDC, ETH/USDC, SOL/USDC

USDC markets are usually thinner than USDT markets, so check the order book before placing a large market order.

A reserve report that only lists wallet balances does not show whether an exchange owes more than it holds. Ours will prove both sides, asset by asset.

1. We commit to every customer balance in a Merkle tree and publish its root.
2. An independent auditor checks the total behind the root and the custodian's wallet holdings.
3. You verify that your own balance is in the tree, in your browser.

• Proof of reserves

We have published a first draft of the public API: market data, order book, trades and candles, plus signed endpoints to place and cancel orders and read balances and fills.

Keys have two scopes, read and trade. There is no withdrawal scope at all, so a leaked key cannot move funds out of an account.

• API reference

• Planned maintenance is announced here and on the status page at least 72 hours ahead.
• We pick the lowest-volume hours of the week where we can.
• Open orders stay on the book unless the notice says otherwise. Deposits sent during the window are credited when it ends.
