Questions.
Do I need to pay to start?
No. A free account gets the guided tutorial and a set of free challenges. The subscription unlocks the rest.
What is a hosted instance?
Some challenges run as a live target launched just for you, on its own address, with a flag unique to that instance. It stays up for an hour and can be extended.
Which cryptocurrencies are accepted?
Checkout runs through a crypto payment processor that supports the major coins, including BTC, ETH, USDT and LTC.
Does the subscription renew automatically?
No. It simply ends after 30, 90 or 365 days. We email you three days before.
Which languages are supported?
The interface is available in English, French, Ukrainian, Chinese and Korean. Challenge content is published in English first.
What does stackd not do?
Everything offensive stays inside the training targets we build. No real-world targets, no stolen data, no ready-made weapons.
