Do you audit contracts deployed on Ethereum mainnet?

Yes. We audit both pre-deployment code and already-deployed contracts. For deployed contracts, we review the verified source on Etherscan and analyze on-chain state.

Do you cover Ethereum L2 deployments?

Yes. We audit contracts targeting Arbitrum, Base, Optimism, and other EVM L2s. L2-specific risks like sequencer dependencies are covered. See our dedicated ecosystem pages for details.

What Ethereum-specific tools do you use?

Slither, Mythril, Foundry (forge), Echidna, Certora Prover, and our internal Sentinel engine. Tool selection depends on the codebase and audit scope.

Ethereum Smart Contract Security Audits

Ethereum secures the largest concentration of on-chain value in crypto. With over $55 billion in DeFi TVL and thousands of active protocols, it's the primary target for sophisticated attackers. Our Ethereum audits cover the full EVM attack surface: from Solidity-specific bugs to protocol-level economic exploits.

Ethereum-Specific Security Risks

Every blockchain has unique security properties. These are the risks specific to building on Ethereum.

EVM Storage & Reentrancy

Ethereum's execution model makes external calls before state updates dangerous. Reentrancy remains a top exploit vector despite years of awareness.

MEV & Front-Running

Ethereum's public mempool enables MEV extraction: sandwich attacks, front-running, and transaction ordering manipulation at the protocol level.

Proxy Upgrade Risks

The majority of major Ethereum protocols use upgradeable proxies. Storage collisions, initialization bugs, and admin key compromises are critical risks.

Composability Exploits

Ethereum's composable DeFi ecosystem means protocols interact in unexpected ways. Flash loan attacks exploit these interactions atomically.

Notable Exploits on Ethereum
