ZK-Rollup Wallet Circuit Review

overview

CORE SERVICE

Smart Contract Development

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

We architect and deploy custom smart contracts that power your core business logic, from tokenomics to governance. Our development process is built on security-first principles and proven patterns.

Full Lifecycle Delivery: From specification and Solidity/Rust development to deployment and monitoring.
Security & Audits: Code follows OpenZeppelin standards and undergoes internal review + third-party audit readiness.
Gas Optimization: Contracts are optimized for minimum execution cost without compromising security.
Compliance Ready: Built-in support for ERC-20, ERC-721, ERC-1155 and custom standards with upgradeability via proxies.

We deliver battle-tested contracts that reduce deployment risk and accelerate your time-to-market by weeks.

SECURITY FIRST

Why a Formal ZK Circuit Audit is Critical

ZK-Rollup wallets secure billions in assets. A single logic flaw in the zero-knowledge proof circuits can lead to catastrophic loss. Our formal audit process systematically eliminates these risks before mainnet deployment.

Prevent Catastrophic Logic Flaws

We identify and remediate critical vulnerabilities in your circuit logic, such as soundness errors that could allow invalid state transitions or double-spends, protecting user funds.

100%

Soundness Verification

Ensure Mathematical Correctness

Our experts validate the underlying cryptographic assumptions and arithmetic constraints of your Plonk, Groth16, or Halo2 circuits to ensure proofs are generated and verified correctly.

Zero

Arithmetic Overflows

Optimize for Gas & Performance

We analyze and recommend optimizations for your circuit's constraint system and proof size, directly reducing on-chain verification costs and improving user experience.

Up to 40%

Gas Cost Reduction

Mitigate Front-Running & MEV

We audit for subtle timing and ordering vulnerabilities specific to rollup sequencers that could be exploited for MEV extraction or transaction censorship.

Proactive

MEV Risk Analysis

Verify Compliance with Specifications

We conduct a line-by-line review to ensure the implemented circuit logic perfectly matches the formal protocol specification and intended wallet behavior.
