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.
Optimistic Rollup Oracle Fraud Proof Mechanisms
Custom Smart Contract Development
Build production-grade smart contracts with battle-tested security and gas optimization.
- Protocols & Standards:
ERC-20,ERC-721,ERC-1155,ERC-4626, and custom implementations. - Security First: Built with
OpenZeppelinlibraries 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.
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.
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.
Witness Data Oracle
A decentralized oracle service that provides the necessary pre-state and transaction data for fraud proof verification off-chain, ensuring provability without centralized dependencies.
Bonding & Slashing Module
Secure economic security layer that manages validator bonds, automates slashing for fraudulent actors, and ensures honest behavior is always the rational choice.
Monitoring & Alert Dashboard
Real-time observability into the health of your fraud proof system, including challenge status, bond levels, and data availability, with configurable alerts for operators.
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.
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.
Formal Verification & Audit Readiness
We develop fraud proof circuits and verifier contracts using formally verifiable patterns (e.g., with K framework) and structure code for seamless audits by firms like Trail of Bits or OpenZeppelin.
Future-Proof Protocol Upgradability
We build upgradeable fraud proof verifiers with clear governance pathways, allowing your rollup to evolve its VM or opcodes without requiring a hard fork of the entire dispute system.
Build vs. Buy: Custom Fraud Proofs vs. Generic Solutions
A direct comparison of the resources, risks, and outcomes associated with developing a custom fraud-proof system in-house versus partnering with Chainscore for a production-ready, audited solution.

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.
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.
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.
Phase 4: Mainnet Launch & Monitoring
We manage the mainnet deployment with you, including contract verification, initializer script execution, and front-end integration. Post-launch, we provide 30 days of enhanced monitoring with real-time alerts for dispute events and system health.
Deliverables: Live mainnet system, monitoring dashboard access, and operational handover documentation.
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your dApp.
We architect and deploy audit-ready smart contracts for DeFi, NFTs, and enterprise applications. Our process delivers gas-optimized Solidity code with comprehensive test coverage, ensuring security and performance from day one.
Reduce your time-to-market with battle-tested development patterns and a focus on security-first design.
- Custom Logic: Tailored
ERC-20,ERC-721, andERC-1155implementations for tokens, marketplaces, and DAOs. - Security Audits: Integration with top firms like OpenZeppelin and CertiK; we fix vulnerabilities before deployment.

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.
