overview
SECURE FOUNDATIONS

Custom Smart Contract Development

Build production-grade smart contracts with battle-tested security and gas optimization.

We architect and deploy secure, auditable smart contracts that power your core business logic. Our development process ensures zero critical vulnerabilities at launch through rigorous testing and formal verification.

  • Protocols & Standards: ERC-20, ERC-721, ERC-1155, ERC-4626, and custom implementations.
  • Security First: Built with OpenZeppelin libraries and audited by leading security firms.
  • Gas Optimization: Achieve up to 40% lower transaction costs through efficient bytecode and storage patterns.

Deploy a fully audited, custom token or DeFi protocol in as little as 2-3 weeks.

ARCHITECTURE BREAKDOWN

Core Components of Our Fraud Proof Architecture

Our modular fraud proof system is built on battle-tested components, ensuring your optimistic rollup is secure, efficient, and ready for production. Each element is designed to minimize trust assumptions and maximize developer velocity.

01

State Commitment Manager

We implement a robust on-chain contract that anchors your rollup's state roots. This is the single source of truth for dispute resolution, built with formal verification for absolute correctness.

Interactive Dispute Game Engine

Our engine automates the multi-round fraud proof challenge process. It handles bisection games, state transition proofs, and on-chain verification, reducing your operational overhead to zero.

SECURITY & ECONOMIC IMPERATIVES

Why a Custom Fraud Proof System is Non-Negotiable

Off-the-shelf fraud proof mechanisms expose your rollup to unacceptable risks. A custom-built system is a core security and economic requirement for any production-grade optimistic rollup.

01

Tailored Dispute Resolution Logic

We architect fraud proofs that precisely match your rollup's execution environment and state transition rules, eliminating false positives and ensuring only invalid state roots are successfully challenged.

Optimized for Your Data Availability Layer

Our systems are engineered for seamless integration with your chosen DA solution (Celestia, EigenDA, Ethereum calldata), minimizing proof generation latency and verification costs specific to your data pipeline.

Minimized Challenge Window & Capital Lockup

We implement aggressive, security-optimized challenge periods (as low as 24 hours for permissioned sets) to reduce validator capital lockup and accelerate finality, improving capital efficiency for your ecosystem.

Resistance to Griefing & DoS Attacks

Our designs incorporate economic disincentives, bond slashing mechanics, and proof bounties to deter malicious or spam challenges, protecting the integrity and liveness of your network.

TRANSPARENT & PREDICTABLE

Our Delivery Process: From Design to Mainnet

A structured, four-phase approach to deliver secure, production-ready optimistic rollup oracle fraud proof mechanisms. We provide clear milestones, regular updates, and guaranteed outcomes.

01

Phase 1: Architecture & Threat Modeling

We design your custom fraud proof system architecture, including data availability layers, dispute resolution logic, and economic security models. This phase establishes the technical foundation and identifies attack vectors before a single line of code is written.

Deliverables: Technical specification document, threat model report, and system architecture diagrams.

2-3 weeks
Typical Duration

Phase 2: Core Protocol Development

Our engineers build the core fraud proof smart contracts and off-chain verifier nodes in Solidity/Rust. We implement battle-tested patterns from OpenZeppelin and follow security-first development practices, including comprehensive unit and integration testing.

Deliverables: Auditable smart contract codebase, verifier node software, and a full test suite.

Phase 3: Security Audit & Testnet Deployment

Your system undergoes a rigorous security audit by our internal review board and optionally, a third-party firm like Spearbit. We deploy to a dedicated testnet (e.g., Sepolia, Holesky) for stress testing and bug bounty programs to ensure resilience.

Deliverables: Audit report, testnet deployment addresses, and a finalized deployment runbook.

Technical & Implementation Details

Fraud Proof Mechanism FAQs

Get clear, expert answers to the most common questions about building and integrating custom fraud proof mechanisms for your Optimistic Rollup.

A standard implementation for a new L2 chain takes 6-8 weeks from design to mainnet deployment. This includes architecture, smart contract development, integration with your sequencer, and a comprehensive security audit. For integrating with an existing rollup stack (like Arbitrum Nitro or Optimism Bedrock), the timeline is typically 3-4 weeks. We provide a detailed project plan with weekly milestones.
