OtterSec

OtterSec is a leading blockchain security firm that has secured over $36.8B in Total Value Locked (TVL) through comprehensive security audits and formal verification services. The firm has identified and patched vulnerabilities worth more than $1B, working with major protocols including Solana Foundation, Wormhole, and Jito Labs. OtterSec pioneered formal verification techniques for Solana programs and continues to develop innovative security tools for the ecosystem. Their team of experienced security researchers has audited over 120 projects, with a 66% success rate in identifying core security issues.

Security Services and Methodology

OtterSec provides comprehensive security services focused on blockchain protocols and smart contracts. Their primary service offerings include security audits, formal verification, and ongoing security monitoring. The firm's methodology combines traditional security assessment techniques with innovative formal verification approaches specifically designed for blockchain environments.

The security audit process begins with a thorough code review, examining smart contracts and protocol implementations for potential vulnerabilities. OtterSec's team analyzes both the technical implementation and the economic design of protocols, ensuring that both the code and the underlying mechanism design are secure. This dual approach has proven particularly effective in identifying complex vulnerabilities that might be missed by more traditional security assessments.

Pioneering Formal Verification

OtterSec has made significant contributions to blockchain security through their development of formal verification techniques. In January 2023, they released the first framework for formally verifying Solana programs, using the Squads Multisig program as their initial case study. This framework integrates with anchor-lang and provides APIs for specifying invariants in Solana code.

Their formal verification approach uses bounded model checking (BMC) to execute programs symbolically rather than concretely. This allows them to verify critical properties of smart contracts mathematically, providing a higher degree of certainty about security properties than traditional testing methods. The firm utilizes the Kani Rust Verifier and has developed a formal-verification-friendly runtime SDK layer to accelerate the verification process.

Major Protocol Partnerships

OtterSec has worked with many of the largest protocols in the blockchain space, particularly within the Solana ecosystem. Notable clients include:

The Solana Foundation has praised OtterSec's work, with Dominic Tsang stating: "As a blockchain, speed, scalability, and security are critical to our everyday operations. OtterSec's responsiveness, attentiveness, and talent are second-to-none when it comes to securing Solana's core code."

Wormhole, one of the largest cross-chain bridges, has relied on OtterSec for security audits of critical infrastructure components. The partnership demonstrates OtterSec's ability to secure complex cross-chain protocols where security is paramount.

Jito Labs, known for their MEV infrastructure on Solana, has worked closely with OtterSec to ensure the security of their protocol. This collaboration highlights OtterSec's expertise in specialized blockchain infrastructure security.

Security Research and Innovation

Beyond their audit work, OtterSec conducts significant security research and develops innovative security tools. Their research has included investigations into Web2 authentication vulnerabilities in Web3 applications, Solana multisig security, and analyses of various blockchain protocols.

The firm regularly publishes detailed security research through their blog, contributing to the broader blockchain security community's knowledge base. Recent publications have covered topics like subverting Web2 authentication in Web3, Solana multisig security, and detailed analyses of various blockchain protocols including Aptos's fungible assets implementation.

The OtterSec Team

OtterSec's team consists of experienced security researchers and engineers with backgrounds in both traditional cybersecurity and blockchain technology. The team combines expertise in smart contract security, formal verification, and protocol design to provide comprehensive security services.

Robert Chen, OtterSec's CEO, is known for his expertise in blockchain security and has spoken at numerous industry events about security challenges and solutions in the blockchain space. The team's technical expertise is demonstrated through their development of novel security tools and frameworks, particularly in the Solana ecosystem.

Security Standards and Best Practices

OtterSec has helped establish security standards and best practices for the blockchain industry, particularly within the Solana ecosystem. Their work includes:

The development of standardized approaches to formal verification of Solana programs, which has become a benchmark for security in the ecosystem. Their framework provides clear guidelines for implementing and verifying security properties in smart contracts.

Creation of security testing methodologies specifically tailored to blockchain protocols, incorporating both traditional security testing approaches and blockchain-specific considerations. These methodologies have been adopted by many projects in the space.
