Secure, production-ready smart contracts built for your specific business logic.
We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process is built on audited code patterns and gas-optimized Solidity 0.8+, ensuring security and efficiency from day one.
We deliver fully functional, auditable contracts in as little as 2-4 weeks.
Our development lifecycle includes:
OpenZeppelin for battle-tested components.Hardhat or Foundry.Typical deliverables include:
ERC-20, ERC-721, or ERC-1155 with minting, vesting, and governance features.We provide complete documentation and a handover session to ensure your team is fully equipped.
Chainscore operates and maintains your dedicated fraud proof relayer, ensuring your Optimistic Rollup is always secure and responsive. We handle the complex infrastructure so your team can focus on application logic.
We guarantee a sub-10-second response time to any fraudulent state root challenge, backed by a 99.9% uptime SLA. Our automated monitoring ensures your rollup's security is never compromised.
We run parallel Geth and Erigon execution clients to independently verify L1 and L2 state. This redundancy eliminates single points of failure and ensures the highest possible data integrity for fraud proofs.
Our system continuously monitors the sequencer and L1 bridge for anomalous activity. We provide real-time alerts and can initiate a fraud proof challenge before malicious state is finalized.
We engineer and submit fraud proofs with gas-optimized transaction bundling and priority fee management, minimizing your operational costs while maximizing proof inclusion speed on Ethereum.
Our relayer infrastructure is built with zero-trust principles, undergoes regular penetration testing, and follows OpenZeppelin Defender best practices for secure private key management.
You get a dedicated engineering lead and 24/7 on-call support. We provide detailed analytics on challenge activity, cost breakdowns, and performance reports to inform your roadmap.
Managing fraud proof relayers in-house demands significant capital, specialized talent, and constant vigilance. Outsourcing to Chainscore Labs provides a production-ready, secure, and cost-effective solution, allowing your team to focus on core product development.
Access a dedicated team of blockchain security engineers and cryptographers with deep experience in Optimistic Rollup protocols (Arbitrum, Optimism). We handle the complex logic of fraud proof generation, submission, and monitoring.
Eliminate the capital expenditure and DevOps burden of running high-availability infrastructure. We manage all hardware, software updates, and 24/7 monitoring, providing a predictable operational expense.
Our globally distributed, multi-cloud relayer network ensures sub-second fraud proof submission with guaranteed service levels. We maintain the infrastructure so you never miss a challenge window.
Benefit from enterprise-grade security practices, including regular protocol updates, intrusion detection, and comprehensive audit trails. Our systems are built with defense-in-depth principles to protect your sequencer's bond.
Deploy a battle-tested fraud proof relayer service in weeks, not months. Avoid the lengthy hiring, R&D, and testing cycles required to build a reliable in-house system from scratch.
We continuously monitor and integrate updates from L2 protocol teams. Your relayer service automatically adapts to new fraud proof mechanisms, opcode changes, and security patches without any action required from your team.
Compare the total cost, risk, and time investment of building a fraud proof relayer in-house versus using Chainscore's managed service.

Time to Production | 6-12 months | 4-8 weeks |
Initial Development Cost | $250K - $500K+ | From $15K/mo |
Core Engineering Team | 3-5 Senior Devs (6+ months) | Our Team (Included) |
Security Audit & Formal Verification | External Cost: $50K - $150K | Included & Continuously Updated |
Uptime SLA & Monitoring | You build it (99.5% typical) | 99.9% Guaranteed |
Fraud Proof Response Time SLA | Not guaranteed (Team-dependent) | < 4 Hours Guaranteed |
Protocol Upgrade Management | Your responsibility (High risk) | Fully Managed |
Total Year 1 Cost (Est.) | $500K - $1M+ | $180K - $300K |
Key Person Risk | High (Specialized knowledge) | Eliminated |
We operate your fraud proof relayer with a battle-tested, security-first process designed for maximum uptime and minimal operational overhead for your team.
We deploy dedicated, high-availability nodes (RPC, sequencer, validator) on secure cloud infrastructure. Each environment is hardened against common attack vectors and configured for optimal performance.
Our team installs and configures the official Optimism or Arbitrum Nitro fraud proof relayer software. We manage all keys, RPC endpoints, and gas strategies to ensure efficient and secure transaction submission.
We implement comprehensive monitoring for chain reorgs, challenge periods, transaction success rates, and gas price spikes. Real-time alerts are sent to our SRE team and your designated contacts.
Our system automatically detects invalid state roots and submits fraud proofs within the challenge window. We manage the entire dispute process, including bond posting and interaction with the L1 contract.
We continuously analyze relayer performance, optimize gas usage, and provide detailed weekly reports on uptime, challenges handled, costs, and network health.
Our dedicated team handles all incidents, from network congestion to protocol upgrades. We ensure seamless migration during hard forks and maintain compatibility with the latest L2 releases.
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our focus is on security-first development using audited patterns from OpenZeppelin and rigorous internal testing to prevent exploits and ensure asset safety.
From tokenization to complex DeFi protocols, we deliver contracts that are gas-optimized, upgradeable, and built for your specific regulatory environment.

Standard integration of our managed fraud proof relayer service takes 1-2 weeks. This includes environment setup, smart contract configuration, and end-to-end testing with your sequencer. Complex customizations or multi-chain deployments may extend this to 3-4 weeks. We provide a detailed project plan at kickoff.
