Blueprint Finance is a core contributor to institutional-caliber DeFi solutions through its dual-protocol system. Concrete powers tokenized DeFi native asset management and the creation of new derivatives for any asset, while Glow enables trading, borrowing, earning, and restaking on Solana. By combining a robust quantitative framework with innovative protocol design, Blueprint transforms complex DeFi mechanisms into secure, reliable products for both institutional and individual users. The company is building the technical foundation for broader institutional adoption of decentralized finance.

Concrete engaged Halborn to address two primary security needs:

• Independent, in-depth protocol review to fully audit smart contracts and underlying assumptions, identifying weaknesses that may not be visible to the internal team.
  

• Proactive threat identification to uncover overlooked edge cases or sophisticated attack vectors that could compromise user funds, disrupt protocol operations, or undermine platform integrity.
  

Halborn delivered a meticulous and methodical code review that detected nuanced vulnerabilities and subtle edge cases that might have otherwise gone unnoticed. This process directly strengthened the resilience and long-term stability of the protocol.

Leo Horstmeyer, Senior Smart Contract Lead at Concrete, stated that “Halborn’s expertise and adaptability gave us complete confidence in our protocol’s security. Their thorough review uncovered subtle issues, strengthened our code, and elevated our team’s security mindset.” 

The Halborn team also showed exceptional flexibility, adapting to Blueprint’s production schedule and tight deadlines to ensure a secure and timely launch without sacrificing the thoroughness of the engagement.

The Concrete team noted that Halborn's responsiveness and adaptability set them apart. They quickly addressed questions, provided actionable feedback, and aligned seamlessly with Concrete’s timelines. The collaborative and highly efficient engagement streamlined the security process from start to finish.

As a result of the engagement, Concrete:

• Achieved meaningful improvements in critical administrative functions, mitigating operational bottlenecks and risks as the protocol scales.
  

• Embedded stronger internal security practices, elevating team awareness and reinforcing a culture of proactive, security-first thinking.
  

• $850M+ value protected through Halborn’s security audit
  

• 35,000+ individual users protected
  

For any DeFi project aiming to launch with confidence, Halborn provides more than just audits. They validate protocol integrity, strengthen operational readiness, and deliver the peace of mind that comes from working with trusted industry leaders.
