Cyfrin debuts Cygent
Cyfrin announced Cygent, an AI 'security engineer' that learns a codebase, joins calls and automatically files fixes as pull requests to remediate issues. The company presented Cygent as an automated assistant for security teams to find and repair code problems, accompanied by demo video coverage. (x.com)
Cyfrin said on April 10 that it has launched Cygent, an artificial intelligence tool that reviews smart-contract code, writes fixes, and opens GitHub pull requests. (cyfrin.io) A smart contract is code that moves crypto assets automatically on a blockchain, so a bug can become a live exploit once the code is deployed. Cyfrin sells security audits for that market and says its platform has helped secure more than $40 billion in decentralized-finance total value locked. (cyfrin.io 1) (cyfrin.io 2) Cyfrin said Cygent is built to do more than flag problems in a report. The company said the tool learns a project’s codebase, works inside developer tools such as GitHub and Slack, and can join Google Meet calls while tracking findings from discovery to resolution. (cyfrin.io) The pitch targets a familiar bottleneck in crypto security work: scanners produce long lists of possible issues, then human engineers spend hours sorting false positives and writing patches. Cyfrin said that handoff from “finding” to “fixing” is where teams lose time and introduce new mistakes. (cyfrin.io) Cyfrin has been adding artificial-intelligence features across its products for months. In December 2025, it launched “AI First Flights,” a training system on CodeHawks that gives auditors instant feedback on practice submissions across 10 on-demand audits. (cyfrin.io) The company has also tied its recent product push to a market where losses remain large. Chainalysis said more than $2.17 billion had been stolen from crypto services by July 17, 2025, and later said total 2025 crypto theft reached $3.4 billion, including $2.02 billion attributed to North Korean hackers. (chainalysis.com 1) (chainalysis.com 2) Cyfrin’s own 2025 year-end summary said it completed more than 75 private audits in 2025, found more than 1,000 vulnerabilities, and expanded its security tooling alongside education products and research. That same post said the firm helped secure $50 billion in total value locked during 2025. (cyfrin.io) The company has framed Cygent as the next step after audits, scanners, and training tools: software that stays with the team after a finding appears and drafts the remediation work itself. Whether teams trust an automated agent to patch production smart contracts will be tested in code review, where every pull request still needs a human decision before merge. (cyfrin.io)
