ZK-Rollup Storage Layer Security Audit

Specialized security audit of the data availability and storage layers within ZK-Rollup architectures. We verify the integrity of state commitments, proof generation dependencies, and fraud-proof mechanisms to secure your L2 infrastructure.

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our focus is on security-first development, gas optimization, and regulatory readiness from day one.

  • Audit-Ready Code: Built on Solidity 0.8+ with OpenZeppelin standards, designed for seamless integration with top auditing firms.
  • Gas-Efficient Logic: We optimize for the lowest possible transaction costs, a critical factor for user adoption and protocol economics.
  • Compliance Patterns: Proactive integration of pause functions, upgradeable proxies, and access control to meet evolving regulatory requirements.

We deliver a production-ready contract suite in 2-4 weeks, complete with deployment scripts, verification, and comprehensive documentation.

Our engineers specialize in:

  • Token Standards: ERC-20, ERC-721, ERC-1155, and custom implementations.
  • DeFi Primitives: Staking pools, liquidity vaults, automated market makers (AMMs).
  • Enterprise Logic: Multi-signature wallets, vesting schedules, and DAO governance modules.

COMPREHENSIVE SECURITY ASSESSMENT

Our ZK-Rollup Storage Audit Scope

We conduct rigorous, line-by-line audits of your ZK-Rollup's data availability and state management layer to eliminate vulnerabilities before mainnet deployment.

01

Data Availability Protocol

Audit of the core logic for publishing and verifying transaction data on L1. We verify the integrity of data commitments, challenge mechanisms, and fraud-proof systems to prevent data withholding attacks.

EXPLORE
02

State Transition & Merkle Trees

Security review of the state root calculation, Merkle Patricia Trie implementation, and state delta management. Ensures the rollup's state is consistently and verifiably updated.

EXPLORE
03

Sequencer & Prover Integration

Analysis of the interface between the sequencer, prover, and storage layer. We check for race conditions, data consistency issues, and liveness failures that could halt the rollup.

EXPLORE
04

Upgrade & Governance Mechanisms

Security assessment of contract upgradeability, timelocks, and multi-sig governance for the storage contracts. Identifies centralization risks and ensures safe, permissioned evolution of the system.

EXPLORE
05

L1 Bridge & Withdrawal Security

Deep dive into the bridge contracts that facilitate deposits and withdrawals. We verify asset safety, message passing correctness, and resistance to replay or censorship attacks.

EXPLORE
06

Economic & Incentive Analysis

Review of staking, slashing, and fee mechanisms that secure the data layer. We model attack vectors to ensure it's economically irrational to compromise the network's data availability.

BEYOND THE CONTRACT CODE

Why a Specialized Storage Layer Audit is Critical

ZK-Rollup security extends far beyond smart contract logic. A dedicated storage layer audit is essential to prevent data unavailability, state corruption, and protocol failure.

01

Prevent Data Unavailability Attacks

We audit your data availability solution (Celestia, EigenDA, EIP-4844) to ensure sequencers cannot withhold transaction data, which would freeze L2 withdrawals and break protocol liveness.

EXPLORE
02

Secure State Transition Integrity

Our review validates the correctness of the state tree (Merkle/Verkle) updates and storage proofs, preventing invalid state roots from being committed to the L1.

03

Audit Bridge & Withdrawal Safety

We rigorously test the storage proofs and fraud/validity proofs used in the bridge contract, ensuring users can always withdraw assets based on provable L2 state.

EXPLORE
04

Optimize Data Compression & Costs

We analyze your calldata/Blob usage and storage schema to identify inefficiencies, potentially reducing L1 data publishing costs by 20-40%.

05

Ensure Upgrade Safety & Governance

We audit storage layout compatibility for upgrades, preventing critical state corruption during protocol migrations or admin key rotations.

06

Mitigate RPC & Indexing Risks

We evaluate the sequencer and node software for consistency in state serving, preventing forks and ensuring reliable data for indexers and end-users.

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom Solidity/Rust smart contracts that are audit-ready from day one. Our development process integrates OpenZeppelin libraries and follows formal verification patterns to mitigate risks before the first line of code is written.

From token standards to complex DeFi logic, we deliver contracts you can stake your business on.

  • Custom Logic: Tailored ERC-20, ERC-721, ERC-1155, and bespoke protocols for your specific use case.
  • Security-First: Rigorous testing with Foundry/Hardhat, plus integration with leading audit firms for final review.
  • Gas Optimization: Expert-level tuning to reduce deployment and transaction costs by up to 40%.
  • Full Lifecycle Support: Development, deployment, verification, and upgrade management via transparent proxies.
