What is CertiK?
CertiK is a blockchain security platform founded in 2018 by computer science professors from Yale and Columbia universities. It was created to meet the rising need for security across decentralised finance and the wider blockchain space, where flaws in smart contracts have led to very large losses.
The CertiK ecosystem runs on its native CTK token and offers end-to-end security services, including smart contract auditing, on-chain monitoring and the SkyNet security scoring system. It applies formal verification, a mathematical way of proving code behaves as intended, alongside AI-assisted tools that flag weaknesses across networks such as Ethereum, BNB Smart Chain, Polygon, Avalanche and Solana.
By its own account CertiK has audited more than 3,800 projects and helped secure a large volume of on-chain value. The CTK token lets holders stake into CertiKShield, a shared reimbursement pool for security incidents, and take part in governance decisions about the platform.

FAQ
Buying CertiK: FAQs
How much do I need to buy CertiK?
Not much at all, because Digital Surge does not set a high minimum on CertiK. You can make a small AUD deposit by PayID and place your first CTK order with that, then add to it later once you are comfortable with how the platform works.
How soon can I buy CTK after registering?
Generally within a few minutes. As soon as your identity check is approved, a PayID deposit of Australian dollars usually arrives in under a minute, so your AUD is ready to use. From there you can buy CTK straight away at the live rate.
Can I sell CertiK and withdraw AUD afterwards?
Yes. You are free to sell your CTK on Digital Surge at any time, turn it back into AUD, and withdraw those Australian dollars to your bank account. Nothing locks your holding in place, and the amount you get back follows the live CTK price when you sell.
What does CertiK actually do?
CertiK audits and monitors blockchain code to find security weaknesses before they can be exploited. It uses formal verification and automated tools, and publishes security scores through its SkyNet system. The CTK token supports this work by powering staking in CertiKShield pools and governance across the platform.
What can I use the CTK token for?
CTK has several roles in the CertiK ecosystem. Holders can stake it into CertiKShield, a pool that helps reimburse users after security incidents, vote on governance proposals, and unlock certain features of the security platform. Beyond that you are free to simply hold CTK in your wallet.
How do I check the live CertiK price in AUD?
The live CertiK price in AUD appears at the top of this page and refreshes through the day, so you always have the current rate in Australian dollars. You can also use the converter to change any AUD amount into CTK, or CTK into AUD, before you decide to buy.
