Smart Contract Security Audits

Comprehensive Smart Contract Security Services

OtterSec provides end-to-end security auditing for smart contracts across multiple blockchain platforms, securing over $36.82 billion in on-chain total value locked (TVL) across 120+ projects. The firm achieves a 66% success rate in identifying core security issues before deployment and has identified and patched vulnerabilities worth over $1 billion.

Audit Process

The audit engagement follows six structured phases: exploratory discussion to understand project requirements, information gathering under MNDA, customized quote based on complexity and risk assessment, audit kickoff with regular status updates, detailed report delivery with vulnerability classifications and remediation recommendations, and ongoing communication throughout the engagement.

Platform Coverage

OtterSec audits smart contracts across Solana (core code and ecosystem protocols), EVM-compatible chains, Sui, Aptos, Cosmos, and Near Protocol. The team has audited critical infrastructure including Solana Core, Account Compression, and Aptos standard library, as well as major protocols like Aave, Kamino, Jito, Raydium, Tensor, Jupiter, MetaMask, and PancakeSwap.

Advanced Testing Methodologies

Penetration Testing

White box and black box testing methodologies address security challenges at the intersection of Web3 and traditional Web2 attack surfaces. Capabilities include wallet security assessments (including deep analysis of MetaMask's Snaps sandboxing environment), exchange infrastructure testing (OAuth misconfigurations and authentication vulnerabilities), backend API security testing, and supply chain security assessments.

Fuzzing and Automated Testing

OtterSec leverages custom-built fuzzing tools including differential compiler fuzzers for Vyper, differential transactional fuzzers for Solana validators, rBPF JIT fuzzers, and Move VM bytecode fuzzers. Discovered vulnerabilities include denial of service vectors in critical infrastructure, memory safety issues, consensus bugs, and state inconsistencies.

Comprehensive Reporting

Audit reports include severity classifications, detailed vulnerability descriptions, proof-of-concept exploits where applicable, gas optimization recommendations, and suggested fixes with implementation guidance. OtterSec maintains a public audit report repository accessible through Notion for transparency.
