Ethereum Audit Services

An Ethereum audit is a professional investigation that documents the origin, movement, and current state of ETH and ERC-20 tokens in your wallets. You need one when banks require proof of legitimate fund sources, for legal proceedings involving crypto assets, tax compliance documentation, or due diligence in business transactions. Our audits provide legally-accepted evidence that your Ethereum holdings are legitimate.

Yes, we provide complete coverage of the Ethereum ecosystem. This includes native ETH, all ERC-20 tokens (including wrapped tokens, stablecoins, and governance tokens), ERC-721 NFTs, and ERC-1155 multi-tokens. We also track interactions with all major protocols and can decode custom smart contract interactions.

Absolutely. We specialize in decoding and documenting complex DeFi activities including liquidity provision on Uniswap and Curve, lending and borrowing on Aave and Compound, yield farming strategies across multiple protocols, liquid staking on Lido and Rocket Pool, and leveraged trading on platforms like dYdX. We translate these technical interactions into clear, understandable documentation.

Yes, we provide comprehensive coverage of the entire Ethereum ecosystem including Layer 2 networks. This includes Arbitrum, Optimism, Base, zkSync Era, Polygon, and others. We can trace funds moving between Ethereum mainnet and L2s through official bridges and third-party bridging protocols, providing complete cross-layer documentation.

We decode all smart contract calls to provide human-readable explanations of what each transaction accomplished. This includes the function called, parameters used, resulting state changes, and the financial impact. For DeFi interactions, we show the before/after positions so you can clearly understand what happened in each transaction.

We can trace Ethereum transactions back to the network's genesis in 2015. This allows us to document the complete history of any wallet, including early mining rewards, ICO participation, and historical DeFi activities. For source of funds purposes, we typically trace back to identifiable sources like exchange withdrawals or mining rewards.

You receive a comprehensive report package including: an executive summary suitable for banks and legal proceedings, complete transaction history with annotations, fund flow visualization diagrams, source identification with verification links, methodology explanation, and supporting spreadsheets. Reports are delivered in PDF format with Excel transaction data.

Yes, we can identify when funds have interacted with mixing services like Tornado Cash. While mixers are designed to obscure direct transaction links, we can document the deposit and withdrawal patterns, timing analysis, and establish probable connections. This information is crucial for compliance purposes and understanding the full transaction history.

Standard Ethereum audits are completed within 5-7 business days. Complex cases involving multiple wallets, extensive DeFi activity, or historical transactions may take longer. We offer priority processing (2-3 days) and urgent processing (24-48 hours) for time-sensitive matters such as legal deadlines or bank requirements.

Yes, our reports are specifically designed to meet banking compliance requirements. We have successfully provided documentation accepted by major banks worldwide for account opening, mortgage applications, and large deposits. Our methodology follows industry standards and reports include all verification information banks require.
