ZK-Rollup Circuit Vulnerability Disclosure Service

A managed, confidential bug bounty program focused on the mathematical soundness and logic of your zero-knowledge proof circuits. We handle researcher coordination, vulnerability validation, and secure disclosure.

overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built to your exact specifications.

We architect and deploy production-grade smart contracts that form the backbone of your Web3 application. Our development process is built on security-first principles, utilizing battle-tested libraries like OpenZeppelin and rigorous internal audits before deployment.

We deliver contracts that are secure by design, not as an afterthought.

  • Custom Logic: Tailored Solidity/Vyper development for DeFi protocols, NFT collections, DAOs, and enterprise applications.
  • Full Lifecycle: From initial design and Hardhat/Foundry testing to mainnet deployment and verification.
  • Security Audits: Optional integration with leading third-party auditors for an additional layer of verification.
  • Gas Optimization: Code reviewed for efficiency to minimize user transaction costs on EVM-compatible chains.

STRUCTURED & SECURE

Our Vulnerability Disclosure Framework

A systematic, confidential process for responsibly reporting and resolving critical vulnerabilities in ZK-Rollup circuits, minimizing protocol risk and protecting user funds.

01

Strict Confidentiality & Legal Protection

All submissions are handled under a legally binding NDA. We ensure researcher anonymity and protect your protocol's reputation by preventing premature public disclosure of vulnerabilities.

Why a Managed ZK Bug Bounty Program

A structured, expert-led vulnerability disclosure program is the most effective way to uncover critical zero-knowledge circuit flaws before they become exploits. We manage the entire process, from attracting elite researchers to validating and remediating findings.

02

Structured Triage & Validation

Our in-house ZK engineers perform initial validation on all submissions, filtering out noise and false positives. We provide you with a detailed technical report, proof-of-concept, and severity assessment (Critical/High/Medium) for each valid finding.

CORE INFRASTRUCTURE

Custom Smart Contract Development

Secure, gas-optimized smart contracts built to your exact business logic.

We architect and deploy production-grade smart contracts that form the unbreakable backbone of your application. Our development process is built on security-first principles, utilizing battle-tested libraries like OpenZeppelin and rigorous internal audits before any code touches the blockchain.

Deliver a secure, auditable, and maintainable codebase that scales with your user base, not your risk.

  • Protocol-Specific Logic: Custom ERC-20, ERC-721, staking mechanisms, DAO governance, and bespoke DeFi primitives.
  • Gas Optimization: Every line of Solidity or Vyper code is written and reviewed for minimum execution cost.
  • Full Lifecycle Support: From initial architecture and development through to deployment, verification, and ongoing maintenance.

ZK Bug Bounty Program FAQs

Get clear answers on how our structured vulnerability disclosure program secures your ZK-Rollup circuits and incentivizes ethical hackers.

Our program follows a structured 4-phase process: 1) Scoping & Setup (1 week): We define the scope, deploy a private bug bounty instance, and set reward tiers. 2) Active Bounty Period (2-4 weeks): Our curated network of 500+ vetted white-hat hackers tests your circuits. 3) Triage & Validation: Our team validates all submissions, replicating exploits and assessing severity using CVSS 3.1. 4) Remediation & Payout: We provide detailed vulnerability reports with PoC code, assist with fixes, and manage all bounty payouts to researchers.
