Security audits for Web3 protocols & dApps
Smart contracts are immutable once deployed — a single missed reentrancy, rounding error, or access control flaw can drain millions in minutes. Over $3 billion has been lost to DeFi exploits that a proper audit would have caught.
CyberAlpha audits Solidity (EVM), Vyper, and Rust (Solana, NEAR) contracts with a blend of formal review, property-based fuzzing with Foundry/Echidna, and symbolic analysis. Our auditors are active DeFi users and have contributed to multiple public bug bounty top-tier reports.
We cover the full Web3 stack: token contracts, AMMs, lending protocols, bridges, staking vaults, NFT collections, DAOs, and governance modules — as well as the off-chain components like oracles, keepers, and frontend integrations.
Schedule a ConsultationImmutable Deployments
Once mainnet code is deployed, a single bug can be exploited repeatedly with no patch window.
Billions Already Lost
$3B+ stolen from DeFi protocols since 2020 — most from vulnerabilities auditors routinely find.
Flash Loan Composability
Attackers can borrow millions with zero capital to manipulate prices and drain vaults.
Public Code, Public Attack
All contract code is on-chain and permanently available for attackers to study.
Web3 exploits are catastrophic and irreversible
