Overview

What Cyfrin actually does.

Cyfrin is a leading smart contract security audit firm that has secured over $50 billion in TVL across multiple blockchains including Solana. The firm conducts thorough manual code reviews of Solana programs written in Rust and Anchor, identifying vulnerabilities before they can be exploited. Beyond auditing, Cyfrin operates Updraft — a free developer education platform that includes a comprehensive Solana Development Course. This combination of security auditing and education makes Cyfrin unique in the space: they both find vulnerabilities in production code and teach developers how to write secure code from the start. Cyfrin's audit methodology covers common Solana-specific vulnerabilities including account validation errors, PDA seed collisions, CPI (Cross-Program Invocation) attacks, and integer overflow issues that are unique to the Solana runtime environment. For Solana teams preparing for mainnet launches, a Cyfrin audit provides the industry-recognized stamp of security that users and investors look for. The free educational content also makes them a valuable resource for developers learning Solana security best practices.
