See it in Action

What is blockchain security?

Blockchain security focuses on safeguarding decentralized networks, smart contracts, and associated assets against vulnerabilities and attacks, including cryptographic protection, consensus integrity, smart contract auditing, and secure key management. This ensures data immutability, transactional safety, and protection from financial, operational, and network-based threats.

How is blockchain security different from traditional IT security?

Unlike traditional IT security, which protects centralized systems and data, blockchain security addresses decentralized architectures, consensus protocols, and smart contracts. It emphasizes immutability, cryptographic integrity, and economic exploits, targeting unique threats such as 51% attacks, Sybil attacks, and DeFi-specific vulnerabilities.

Are dApps and Web3 front-ends part of blockchain security?

Yes. dApps and Web3 front-ends interact directly with smart contracts and blockchain networks, making them critical security points. Vulnerabilities in authentication, API integrations, or user interfaces can compromise user funds and data, so auditing these layers is essential for end-to-end blockchain security.

How long does a smart contract audit usually take?

A smart contract audit typically takes 10-15 business days, depending on the complexity, contract size, and the number of network integrations. Comprehensive audits include automated scanning, manual review, and logic testing, with additional time for revisions, re-audits, or integration checks for DeFi protocols or multi-contract systems.

How do I choose the right blockchain security vendor?

Select vendors with proven experience, a portfolio of completed audits, contributions to OWASP or blockchain security standards, and knowledge of your target chain. Evaluate their methodology, reporting clarity, and client references to ensure comprehensive coverage of smart contracts, networks, and DeFi protocols.
