CyStack officially launched the Smart Contract Audit service v2.0, helping protect Blockchain and Cryptocurrency projects from cybercriminals.


As one of the leading companies in security testing in Vietnam and in the region, CyStack understands the huge security risks of technology projects, especially with Blockchain and Cryptocurrency projects because even a small mistake in implementation can lead to hackers breaking in and stealing or causing millions of dollars worth of damage.

With experience in implementing security testing for many technology enterprises, including Blockchain and Cryptocurrency projects, CyStack officially launched the Smart Contract Audit v2.0, a security testing service for Smart Contracts on Blockchains. This promising service is expected to be a solid stepping stone to protect Blockchain projects from cybersecurity risks from hackers, and help them gain more trust from customers and investors.

Introducing Smart Contract Audit v2.0 service with improvements

Smart Contracts play an important role on the Blockchain network. The implementation of smart contracts on the blockchain network needs to be done correctly, because if there are errors or security weaknesses, it is very likely that hackers will easily attack and steal a large amount of assets, as well as cause damage to business operations.

CyStack’s Smart Contract Audit service focuses on finding the cybersecurity vulnerabilities and mis-implementation of Smart Contracts on the Blockchain networks, thereby suggesting remediation plans to help deploy the Smart Contracts correctly and safely, contributing to protecting the project against the risk of being attacked by hackers.

The testing and analysis process is carried out methodically by highly skilled security engineers, using dynamic analysis tools and manual source code review, to comprehensively check for possible risks to the Smart Contract.

The DeFi platform named Polynetwork was hacked due to a Smart Contract error causing a loss of $600 million in September 2021.

After going through many security audit projects for Smart Contracts, we decided to upgrade the service to better support Blockchain and Cryptocurrency projects:

  • Standardizing the test checklist according to SWC.
  • Adding the option of testing decentralized applications D-apps, Crypto Wallets, testing consensus algorithms on the Blockchain network.
  • Extending the auditing for Custom Smart Contracts, instead of limiting to Solidity, JavaScript, Rust, Go languages as before.
  • Adding the option to receive a quick report within 3 – 5 days (Express Delivery) along with the old option with the testing frame of 7 – 14 days.

Thus, along with the constant benefits of the previous Smart Contract Audit service, customers will receive the best value when using CyStack’s Smart Contract Audit v2.0 service.
