Method
How do Bitcoin project audits work?
The audit process kicks off with a detailed analysis of a project's entire codebase.
On occasion and when deemed necessary, CertiK reserves the right to conduct a Team Verification (KYC) check on a project it suspects to be high risk.

We have published multiple research articles covering the Bitcoin ecosystem's evolution and security considerations.
Research reportsLiquid Network Incident AnalysisOn 6 September 2026, the Liquid Network was exploited through a vulnerability in the Elements codebase used to validate Confidential Transactions. The issue stemmed from an ambiguous cache-key encoding in the rangeproof verification cache, allowing two different validation inputs to produce the same cached entry. 
Ecosystem analysisCEX H1 2026 Review: Volume Cools, Balance Sheets DecideThis H1 2026 review compares centralized exchanges by spot and futures volume, open interest, reserve depth, Bitcoin custody, and expansion into tokenized stocks and traditional financial products.
Technical insightsDesigning Proof of Reserves for Tokenized GoldWhen you buy a real world asset like tokenized gold, the token lives on-chain, but the gold does not. It sits in a vault, managed by a custodian, documented through paper records and serial numbers. The chain confirms you own the token, but it cannot confirm the gold exists.
Technical insightsWhat is a Privacy Coin?Privacy coins are cryptocurrencies engineered to enhance user anonymity by obscuring transaction data (such as sender identities, transaction amounts transferred, transaction history, etc.). Unlike pseudonymous digital currencies such as Bitcoin (BTC), privacy coins employ advanced privacy-enhancing cryptographic methods to mimic the untraceability of physical cash in the Web3 ecosystem.
Technical insightsExploring PSBT in Bitcoin DeFi: Security Best PracticesIn this article, we share our extensive research and insights into PSBT, delving into its components, applications in Bitcoin DeFi, and the security risks associated with improper usage. We aim to highlight best practices for secure PSBT implementation and contribute to the ongoing efforts to strengthen Bitcoin ecosystem security.
Technical insightsClarity: Best Practices and ChecklistsClarity is a smart contract language developed collaboratively by Hiro PBC, Algorand, and other stakeholders. It is currently utilized on the Stacks chain (Bitcoin sidechain). The primary goal of Clarity is to provide a high level of predictability and security, ensuring that smart contracts behave as intended without any unexpected side effects.In this article, we explore the concept behind Clarity smart contracts, as well as best practices and security checklists for programming with Clarity.
