Our verdict
OSL is a licensed, custodial exchange for people who put regulatory standing and published reserves above a long coin list. Regulated in Australia, Austria and Hong Kong, it publishes proof of reserves, yet lists just 22 coins, so it suits focused holders rather than explorers.

Frequently asked questions
Is OSL regulated?+
Yes. It is registered with AUSTRAC as a crypto exchange provider and remittance service provider, authorised by the Austrian Financial Market Authority as a MiCAR crypto-asset service provider, and licensed by the Securities and Futures Commission, Hong Kong as a virtual asset trading platform.
What does OSL do with my crypto?+
Custody is custodial, so the platform holds the assets on your behalf rather than giving you keys. The account works from a mobile app, so access is through the exchange rather than a self-custody wallet.
How many coins can I trade?+
The listing covers 22 coins, which is a focused set by exchange standards. Anyone wanting a long tail of assets for general speculation would find more choice elsewhere.
How do I add money to my account?+
Fiat deposits run by bank transfer, listed as bank. No card or wallet rails are named, so plan around having a bank account to move money from.
Does OSL show proof of reserves?+
Yes, proof of reserves is published, which lets you check the exchange is holding assets against its obligations. It is one of the more reassuring signals on safety for a custodial platform.
Can I trade derivatives?+
Yes, derivatives are offered alongside the spot market. That suits traders who want to take a position rather than only buy and hold coins.
How is OSL priced?+
The listed price is $0, so there is no charge for opening or using the account itself. Trading costs still apply per trade, and the coin list is limited to 22.
Who is OSL based in?+
The operating entity is OSL EU GmbH, headquartered in Austria, and the exchange was founded in 2018. Austrian headquarters sit alongside the European authorisation.
How do I get help?+
Support runs on chat, email and help centre, so help comes through live chat, email and a help centre. There is no phone line listed, which matters if you prefer to talk someone through a problem.
