Blockchain pentest service from Datami

Blockchain penetration testing is a controlled simulation of an attack to identify vulnerabilities in smart contracts, network nodes, APIs, cryptography, and tokenomics logic.

It increases platform security, strengthens user trust, prevents theft of funds, data leaks, and the blocking of critical processes.

Smart contract analysis

Detection of vulnerabilities in the code that manages financial transactions and protocol logic. A mistake can cost millions.
Decentralized infrastructure assessment

Verification of nodes, synchronization, consensus, and possible attack points in the P2P network, integration with other systems.
Cryptography and tokenomics check

Security analysis of keys, wallets, signatures, encryption, and economic logic (inflation, token manipulation).

Specifics of blockchain pentesting

Penetration testing of a blockchain system provides a comprehensive understanding of potential threats to the project. It is carried out under the full control of the client and creates no risks for the infrastructure.

A blockchain pen test has a number of specific features: it takes into account the absence of centralized control, involves deep analysis of code, cryptography, and tokenomics specifics. This requires high qualifications and practical experience from the team of pentesters.

Irreversibility of transactions. In blockchain, an action cannot be “rolled back”, even accidental or malicious. Therefore, testing takes into account scenarios with irreversible consequences.
High-level financial risks. Blockchain projects often operate with tokens or cryptocurrency. Even a minor error can lead to loss of assets or reputation.
Specific attack vectors. Penetration testing covers threats unique to blockchain: front-running, flash loan attacks, gas fee manipulation, etc.

Business benefits

Advantages of blockchain pentests

Penetration testing is recommended for DeFi, NFT, and Web3 projects, crypto exchanges, wallets, fintech startups, DAOs, and token-based companies.

It identifies security weaknesses to eliminate them in advance and leave no chance for hackers. After all, even one vulnerability can cost millions.

By ordering a blockchain pentest from Datami, you will get:

Improved protection. We detect vulnerabilities that could lead to attacks, data leaks, or theft of cryptocurrency or tokens.
Professional report and recommendations. We provide a structured report with risk levels and step-by-step guidance on problem resolution.
Free retest. After vulnerabilities are fixed, we will conduct a follow-up check - at no extra cost.
Compliance and audit. Our report can be used as official proof of security for partners or regulators.
Trust in the platform. Testing increases reputation and demonstrates a responsible approach to security.
Readiness for launch. A pentest is a crucial step before launching smart contracts, a platform, or listing a token.

Datami work standards

Our approach to blockchain pentesting

The Datami pentesting team simulates real attack scenarios and uses the methods of modern hackers, without any risk to your infrastructure. We apply the most effective tools and technologies.

Depending on the level of access, we choose black-, gray-, or white-box approaches. We provide practical reports with vulnerability prioritization and actionable recommendations to improve security.

Confidentiality without compromise

We work strictly under NDA. All actions are agreed upon with the client before testing begins.

Testing tailored to the client’s business

We consider the specifics of the company and create a testing plan tailored to your goals and risks.

Automation + manual expertise

We combine automated tools with manual analysis and custom attack scenarios.

Vulnerabilities detected by pen testing

Key threats to blockchain systems

01.

Dangerous external calls

Interaction with an unverified contract allows a hacker to alter execution logic.

02.

DoS attacks

A function is blocked by the attacker, making the contract unavailable or non-functional.

03.

Integer overflow or underflow

Arithmetic errors allow balance manipulation or bypassing restrictions.

04.

Access control issues

Incorrect authorization exposes critical functions to unauthorized users.

05.

Reentrancy

An attacker repeatedly calls a function before the previous execution finishes, bypassing contract logic.

06.

Unsafe token logic

Errors in standard implementation allow balance changes or bypassing validations.

07.

Weak cryptography

Unreliable algorithms or implementation errors put data security at risk.

08.

Timestamp manipulation

An attacker manipulates block timestamps to bypass conditions or alter outcomes.

09.

Transaction front-running

A hacker front-runs your transaction, gaining financial advantage.

Frequently asked questions

Penetration testing is mandatory before project launch and should be repeated after every significant change in code or architecture.

Usually from 1 to 3 weeks. The duration depends on project specifics, system scale, smart contract complexity, and service urgency.

The price is determined by the size and complexity of the project, the number of smart contracts, the scope of infrastructure, and the depth of analysis.

Yes. We recommend rechecking security, as any changes in code or logic may create new vulnerabilities.

Not necessarily - smart contract auditing is part of penetration testing, but it can be ordered separately if required.

It depends on the chosen approach: white-, gray-, or black-box. Source code speeds up and deepens testing, but testing is also possible without it.
