Are Arbitrum audits different from Ethereum mainnet audits?

The core Solidity review is the same, but we add L2-specific coverage: sequencer dependency analysis, cross-chain message handling, gas model differences, and delayed finality risks.

Do you audit Arbitrum Orbit chains?

Yes. We audit custom Orbit chains including modified sequencer configurations, custom gas tokens, and chain-specific modifications.

Do you cover cross-chain interactions between Arbitrum and Ethereum?

Yes. Any protocol that bridges assets or sends messages between Arbitrum and L1 (or other L2s) gets cross-chain risk coverage as part of the audit.

Arbitrum Smart Contract Security Audits

Arbitrum is one of the largest Ethereum L2s by TVL, hosting major DeFi protocols and handling billions in daily transaction volume. While it inherits EVM compatibility, it introduces L2-specific risks (sequencer dependencies, delayed finality, and cross-chain message handling) that require specialized audit coverage.

Arbitrum-Specific Security Risks

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

Sequencer Dependency

Arbitrum's centralized sequencer creates a single point of trust for transaction ordering. Protocols must handle sequencer downtime, delayed inclusion, and ordering manipulation.

Cross-Chain Message Risks

Messages between Arbitrum and Ethereum (or other L2s) have finality delays. Protocols that don't account for this can have state inconsistencies exploited.

Gas Pricing Differences

Arbitrum's gas model differs from Ethereum mainnet. Contracts optimized for mainnet gas may behave differently or have unexpected costs on L2.

Standard EVM Risks

All standard Solidity vulnerability classes apply: reentrancy, access control, oracle manipulation, flash loan attacks.
