There are dangers associated with smart contracts technology, with millions of DApps and ICO,
some people intentionally engage in activity that is harmful to the whole community.

These malicious activities are only possible when vulnerabilities exist in smart contract code.

Many hacking incidents resulted from the lack of appropriate smart contract auditing.
Examples of such hacks are the, now famous, DAO hack (50 million dollars), the Parity Multi-Sig Wallet hack (300 million dollars)
or the Parity Freeze (513,000 Ether).

What a Smart Contract can do?

What is a Smart Contract?

This is one of the most widely used terms in cryptocurrency, so what is a smart contract?

The term smart contract refers to software code or a protocol used to contribute to, verify, or implement an agreement’s negotiation, or performance. Allowing credible transactions without third parties, they can be initiated automatically and are fully programmable.

People can use smart contracts to create and use Dapps or ICOs.

Trust the blockchain, audit your smart contracts

Are Your Funds Safe?

Smart contract programming is a new field, lacking security standards, documentation, and good practices; therefore, some developers neglect to audit their smart contracts before their launch.

A smart contract must be carefully planned, considering all logical permutations, accommodating all possible exceptions, and rigorously implemented. An error in the code order (as DAO hack) or an initialization omission (as Parity Freeze) can lead to a disaster, immortalized on the immutable blockchain.

With the evolution of blockchains, new smart contract development platforms will emerge; however, code security is eternal in programming. The audit of the smart contract’s code will remain a requirement for any project, be it an ICO or any other DApp, to be considered safe and ready to receive the user’s funds.

Several major hacking incidents have been reported due to a lack of smart contracts auditing.
Despite popular belief, a smart contract is not safe by nature.
As a code, it is as subject to bugs and flaws as any program.
To withstand years of hacking attempts, smart contracts
must be programmed with
a 100% accuracy.
An audit of smart contracts intended to receive funds
is mandatory.

Uncompromising safety

Callisto Security Department

We founded the Callisto Security Department to reduce the risks/flaws in smart contracts by helping developers improve the adoption of programmable blockchains.

Therefore, we aim to improve the overall security of the entire crypto industry without limiting ourselves to any project.

Another crucial point is the way we perform security audits. We believe that automated tools and formal verification cannot provide sufficient security for mission-critical systems and DApps, which is why we rely on real auditors to perform our audits.

Proof of Safety

Safety as a proof of excellence

Since 2018, our auditors have conducted over 300 smart contract security audits, covering many significant projects. In line with our primary goal, we have initiated the Proof of Safety program, designed to highlight projects whose smart contract is highly secure.

Proof of Safety consists of a customized document providing a clear and comprehensible summary of the audit report, intended to the community and investors.
