Largest Ethereum L2

Arbitrum Audit Services

Professional blockchain investigation for the Arbitrum ecosystem. Track ARB transactions, analyze GMX derivatives, and document fund origins on Ethereum's leading optimistic rollup.

Arbitrum

Ethereum's leading optimistic rollup

Arbitrum is the largest Ethereum Layer 2 by total value locked, home to a thriving DeFi ecosystem and the leading decentralized derivatives platforms. With GMX pioneering decentralized perpetual trading and protocols like Camelot building innovative DEX mechanics, Arbitrum has become a hub for sophisticated DeFi users.

As an optimistic rollup, Arbitrum inherits Ethereum's security while offering dramatically lower transaction costs. This has attracted significant capital and trading volume, creating complex transaction histories that require specialized expertise to properly document and analyze.

Our Arbitrum expertise covers the complete ecosystem: GMX and derivatives trading, DeFi protocols, the ARB governance token, and comprehensive L1-L2 bridge tracking that maintains provenance continuity with Ethereum mainnet.

Why Do You Need an Arbitrum Audit?

Understanding the unique aspects of documenting Arbitrum activity

Derivatives Trading Complexity

Arbitrum hosts sophisticated derivatives platforms like GMX where users trade with leverage, manage collateral, and face potential liquidations. Documenting this activity for taxes requires understanding position mechanics, fee structures, and accurate PnL calculations.

Our team has deep GMX expertise, decoding all position-related transactions and calculating gains and losses accurately for tax reporting.

ARB Token Compliance

The ARB airdrop was one of the largest in crypto history, with significant tax implications for recipients. Additionally, ARB is used for governance, staking, and trading—all activities that need proper documentation.

We document airdrop claims with eligibility proof, and track all subsequent ARB token movements for complete compliance documentation.

Arbitrum Audit FAQ

What is an Arbitrum audit and why is it different from other L2 audits?

An Arbitrum audit traces the origin and movement of ARB, ETH, and tokens on the Arbitrum network—Ethereum's largest Layer 2 by TVL. Arbitrum's unique ecosystem includes significant derivatives trading on GMX, sophisticated DeFi protocols, and the ARB governance token. Our audits cover these Arbitrum-specific elements while maintaining provenance continuity with Ethereum mainnet.

Can you track funds from Ethereum to Arbitrum?

Yes, we provide complete L1-L2 bridge tracking. We trace funds from Ethereum mainnet through the official Arbitrum bridge (with its ~7 day withdrawal period) as well as fast bridges like Stargate, Hop Protocol, and Across. Our documentation maintains full provenance continuity showing the L1 origin of L2 funds.

Do you analyze GMX and derivatives trading?

Yes, we have deep expertise in Arbitrum derivatives protocols. For GMX, we decode all interactions including position opens/closes, leverage adjustments, liquidations, and GLP minting/burning. We calculate PnL for each trade and provide complete trading history documentation. We also cover Gains Network, Vela, Dopex, and other Arbitrum derivatives platforms.

Can you verify and document ARB airdrop claims?

Yes, we can document ARB airdrop eligibility criteria, the claim transaction, and all subsequent ARB token movements. This includes documenting the original activities that qualified for the airdrop, the claim itself, and whether tokens were sold, staked, or used for governance. Essential for tax reporting of airdrop income.

What Arbitrum DeFi protocols do you cover?

We cover all major Arbitrum DeFi protocols including Camelot DEX, Uniswap, Sushiswap, Radiant Capital (lending), Pendle Finance (yield), Jones DAO, and 80+ others. We decode liquidity positions, farming deposits, lending/borrowing, and reward claims into human-readable documentation.

Do you support Arbitrum Nova?

Yes, we support both Arbitrum One (the main network) and Arbitrum Nova (optimized for gaming and social applications). We can track funds on either network and trace assets moving between them. This is important for gaming platforms and applications that use Nova for lower costs.

How do you handle Arbitrum's withdrawal period?

Arbitrum's optimistic rollup design includes a ~7 day challenge period for withdrawals to L1. We document when withdrawals are initiated, track their progress, and note when they become claimable. For fast bridges, we track the immediate cross-chain transfers separately.

What documentation do I receive with an Arbitrum audit?

You receive a comprehensive report including: executive summary, complete transaction history with decoded interactions, derivatives position documentation with PnL, bridge transaction tracking showing L1-L2 continuity, DeFi position analysis, and supporting spreadsheets. Reports are formatted for tax, compliance, or legal use.

How long does an Arbitrum audit take?

Standard Arbitrum audits are completed within 5-7 business days. Wallets with extensive GMX trading, complex DeFi positions, or significant cross-chain activity may take longer. We offer priority (2-3 days) and urgent (24-48 hours) processing for time-sensitive needs.

Will banks accept Arbitrum audit reports?

Yes, our Arbitrum reports are designed for banking compliance. The key is demonstrating fund provenance back to Ethereum mainnet and ultimately to regulated exchanges. We clearly document bridge transactions and L1 sources to create verifiable fund trails that banks accept.
