What is Shentu?
Shentu (CTK), formerly CertiK Chain, is a blockchain focused on security for the wider crypto ecosystem. It pairs a public chain with tools aimed at protecting smart contracts and users, including the Shentu Security Oracle, which produces on-chain security scores, and ShentuShield, a community pool that can reimburse losses from hacks or code failures. CTK is the network's native coin. It is used to pay gas fees, to stake and help secure the chain through its delegated proof-of-stake design, and to fund and reward participation in security analysis and governance. The project grew out of CertiK, a blockchain auditing firm founded in 2018, and the chain later rebranded from CertiK Chain to Shentu. The network sits alongside an active commercial auditing business, which gives it a clear purpose within crypto security. You can check the Shentu price and hold CTK in a self-custody wallet.

What's the best Shentu wallet app?
That depends on what you want to do with your CTK. If you're holding only, any non-custodial wallet works. If you want to hold, swap across 20+ chains, connect to dApps, and use crypto for real-world spending, Zypto App is purpose-built for that while still being fully non-custodial.
