Solana audits ensure DApp security, especially with Rust-based smart contracts. Leveraging expertise in Solana's architecture, auditors identify vulnerabilities and mitigate risks through a comprehensive, tailored approach for Rust-based code.

Solana programs rely on AccountInfo::is_signer to verify if a transaction is signed by the authorized account. Missing this check can allow unauthorized access.
Programs should verify the AccountInfo::owner field to ensure accounts are used as intended. Not checking ownership could lead to unintended consequences.
Solana limits nested program calls to prevent complex attacks; understanding this is vital to avoid related vulnerabilities.
Rust offers default memory safety, but unsafe blocks can bypass these safeguards. We Careful review it to avoid memory corruptions like buffer overflows.
Anchor simplifies development, but over-reliance on its abstractions can obscure Solana concepts, potentially introducing unnoticed vulnerabilities.
Anchor projects rely on external dependencies. Updating these dependencies is crucial to addressing any security issues in those libraries.

Rust Smart Contract Security Best Practices
We check best practices for secure Rust development in smart contracts, such as using libraries and tools designed for secure coding in the Solana ecosystem.
Account Ownership & Permissions
Assess how the smart contract manages account ownership and access control mechanisms. Look for vulnerabilities that could allow unauthorized access or manipulation of accounts.
Solana Program Libraries (SPLs)
Analyze the use of SPLs (standardized libraries) within the smart contract for known vulnerabilities or potential misuse.
Cross-Program Invocations (CPIs)
Evaluate how the smart contract interacts with other Solana programs through CPIs. Identify vulnerabilities in how data is passed or how responses are interpreted.
Syscalls & Solana Runtime
Assess the use of system calls provided by the Solana runtime environment. Ensure proper error handling and validation for any interaction with the runtime.
Memory Safety
Evaluate the code for potential memory safety issues like buffer overflows, use-after-free, and dangling pointers, which can lead to code execution attacks. Tools like cargo memory can assist in this process.
Integer Overflow/Underflow
Analyze for potential integer overflow or underflow vulnerabilities that could lead to unintended behaviour or manipulation of values within the smart contract.
