FAQ
What are smart contracts and why do web3 projects rely on smart contracts?
Smart contracts are digital contracts that automatically execute financial transactions once specific terms and conditions are met. They make up the foundation of crypto trading and decentralized finance.
Smart contracts ensure safety, accuracy, and high speed of interaction. When predetermined conditions are met, the actions are executed automatically. Smart contracts ensure trust and transparency between the parties involved. When coded without errors and weaknesses, smart contracts can ensure the ultimate security of transactions.What is an ERC-20 (Ethereum) smart contract audit?
The audit process consists of vulnerability assessments of smart contracts deployed on the Ethereum network as well as identification of security flaws and network vulnerabilities. The audit team will review existing security practices that the project uses in its smart contracts. The auditing firm will also provide recommendations to the project team on security policies and better security controls designed to protect the project from new issues.What token standards are supported by ERC-20 audit?
In addition to ERC-20 audit, we support all common token standards running on the Ethereum blockchain, including ERC-20, ERC-1155, ERC-4626, ERC-721, ERC-777, ERC-2535 standards.What are ETH smart contract security risks?
They may seem like complicated systems, but all smart contracts are still computer programs or protocols with function statements and variables that are vulnerable to hacks and exploits. Many smart contracts are fraudulent in nature: unethical actors insert malicious functionality to get unauthorized access and steal money. In our practice, we have seen dozens of unique and repeated loopholes inserted in the code. Besides, some parts of the protocol can be of low quality in terms of protection. Hackers carefully study all the errors and try to capitalize on them. There is a real risk of losing hundreds, thousands, or even millions of dollars due to exploits of smart contract vulnerabilities. A full audit by a team of professionals will help protect your financial interests by identifying and removing all vulnerabilities and exploits.Can I conduct a smart contract audit myself?
We encourage projects to use their internal resources to review smart contracts. Internal audits can identify vulnerabilities. However, there is extra value to professional audit. A third-party auditing team offers an external call. This is the only way to receive an authoritative opinion and informed recommendations on your code from the outside. On top of that, the internal team may lack the necessary expertise or time to comprehensively review a smart contract. External audit firms have entire teams that specialize in security research and smart contract vulnerability assessment.What benefits does a company get by passing an Ethereum contract audit?
Most hacks are attributable to ETH projects because Ethereum is the most popular chain for smart contracts. Ethereum contract audit allows a company to detect and then eliminate vulnerabilities in a smart contract by exploiting which attackers can cause serious damage to this company and its clients. The passed audit will also serve as a confirmation of the company’s reliability for potential partners and investors.Where can I find examples of Ethereum smart contract audit reports?
All audit reports (if public) can be found in the “Audits” section at hacken.ioCan I trust Hacken?
In our five years of experience as a Web3 cybersecurity organization, we have audited more than 1,500 projects on all possible chains. We provide other cybersecurity services, such as Penetration Testing, dApp Audits, Bug Bounties, and Proof of Reserves.
