Question 1

What is a dApp?

Accepted Answer

dApp (Decentralized Application) is an application that interacts with a blockchain in one form or another (e.g. calls or reads from Smart Contracts; blockchain indexing, etc.). Usually, it helps with achieving something that is not possible with just Smart Contracts (like random), or for indexing some information that is not easily accessible through the blockchain directly (transaction history, custom Smart Contracts events, etc.). Ensure secure blockchain interaction with dApp audit. dApps, such as wallets and cross-chain bridges, are connected to the blockchain. Most projects only audit smart contracts paying no attention to off-chain vulnerabilities. Hacken’s dApp audit is the best available choice for projects that want a high level of security. Focused on the off-chain code review, our dApp audit prevents the leakage of a private key and ensures a secure interaction of your dApp with the protocol.

Question 2

What coding languages are dApps based on?

Accepted Answer

The dApp code can be written in any programming language. Most dApps are written in Java, Python, JavaScript, C#, and Rust.

Question 3

What is the difference between a dApp and a smart contract?

Accepted Answer

dApp is not a Smart Contract. This is a normal application (client – something you can see with your eyes and interact with, or server – something that is hidden behind the UI) that interacts with one or several blockchains. It is not deployed on the blockchain, it deploys like a regular Web 2.0 application; the logic can be changed in the future after the deployment. dApps use smart contracts to authorize transactions and interact with blockchain. Smart contract code is not the only code of a dApp. dApps also have off-chain code that doesn’t interact with the blockchain. This off-chain code is the target of the dApp audit.

Question 4

What are smart contracts used by dApps?

Accepted Answer

dApps are deployed on blockchain and use smart contracts for app logic. Smart contracts are digital contracts that automatically execute transactions once predetermined conditions are met.

Question 5

What are the security challenges of dApp? How secure are dApps?

Accepted Answer

The most common exploits in the dApp audit environment are overconfidence in a node (or node provider), failure to account for blockchain branching out, incorrect validation of ENS records, weak authentication via message signing, unsafe private key storage, XSS/SQL injections from the blockchain data, misuse of checksum addresses, blockchain data inconsistency, incorrect integration with a smart contract and/or blockchain platform, usage of wrong data types, application architecture, repository consistency, code style consistency, and deprecated, vulnerable, or outdated Web3 libraries.

Question 6

What are the dApp security improvement practices?

Accepted Answer

Deploying a dApp to the blockchain is different from traditional app development because making any changes after is difficult. Therefore, it’s vital to ensure security and the absence of any bugs before the launch. dApp security improvement practices are smart contract audit for the on-chain code and dApp audit for the off-chain code. The dApp security audit performed by Hacken experts covers both the back-end and front-end of the decentralized app. A comprehensive dApp audit by a team of professionals will help protect your financial interests by identifying and removing all vulnerabilities and exploits. dApp Audit by Hacken will help your project expand the possibilities of decentralized networks in finance, arts & collectibles, gaming and technology, and other segments. With a dApp audit, you can ensure that all blockchain superpowers, such as built-in payments, secure on-chain data, and user credentials, work as intended.

Question 7

Can I conduct a dApp audit myself?

Accepted Answer

We encourage projects to use their internal resources to review their dApps. Internal audits can identify vulnerabilities. However, there is extra value to a professional dApp 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 review dApp comprehensively. External audit firms have teams specializing in security research and dApp vulnerability assessment.

Question 8

Will I get recommendations on how to address detected issues after an audit?

Accepted Answer

Hacken specialists will provide you with a report containing step-by-step client-friendly recommendations on how to eliminate detected issues.

Question 9

What is the duration of a dApp audit?

Accepted Answer

The duration of a dApp contract audit varies depending on the audit scope and complexity. Generally, the audit duration is specified before the process starts so that a customer is aware of each stage in the process.
