Optimistic Rollup Restaking Bridge Architecture
Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
- Protocol Development: Custom
ERC-20,ERC-721,ERC-1155, and bespoke token standards. - DeFi & DEX: Automated Market Makers (AMMs), liquidity pools, staking, and yield farming vaults.
- NFT Ecosystems: Generative minting, royalty enforcement, and marketplace logic.
- Security Audits: Every contract undergoes internal review and is prepared for third-party audits.
We deliver fully documented, gas-optimized contracts with a 99.9% uptime SLA for mainnet deployments, enabling you to launch with confidence.
Core Technical Components We Deliver
We build the foundational infrastructure for your Optimistic Rollup restaking bridge, delivering production-ready components with enterprise-grade security and performance.
Custom Bridge Smart Contracts
Secure, gas-optimized Solidity contracts for depositing, withdrawing, and managing restaked assets. Built with OpenZeppelin libraries and formal verification patterns for maximum security.
Fault-Proof & Challenge System
Core logic for detecting and disputing invalid state transitions on the L2. Implements a multi-round interactive fraud proof protocol with economic security guarantees.
Cross-Chain Messaging Layer
Reliable message passing between L1 and L2 for deposit finality and withdrawal proofs. Supports native bridges (Optimism, Arbitrum) and custom rollup SDKs.
Restaking Module & Slashing Logic
Smart contract suite for managing validator stakes, delegation, and slashing conditions. Enforces economic security for the bridge's fault-proof system.
Sequencer & Prover Infrastructure
High-availability node infrastructure for transaction sequencing, batch submission to L1, and zero-knowledge proof generation (if required).
Monitoring & Alerting Dashboard
Real-time observability into bridge health, transaction flow, validator status, and security events. Provides alerts for failed batches or slashing conditions.
Why Build a Restaking-Secured Bridge
Our Optimistic Rollup bridge architecture leverages EigenLayer's restaking ecosystem to deliver a new standard in security, cost, and interoperability for institutional-grade cross-chain applications.
Radical Cost Reduction
By leveraging the shared security of the Ethereum staking pool, you eliminate the need to bootstrap and incentivize a dedicated validator set. This cuts operational costs by over 80% compared to building and maintaining a standalone Proof-of-Stake bridge.
Faster Time to Mainnet
Our modular bridge framework is built on battle-tested optimistic verification. We provide a production-ready codebase, cutting development time from 6+ months to under 8 weeks. Focus on your application logic, not the bridge's consensus mechanism.
Future-Proof Interoperability
Built as an EigenLayer AVS, your bridge automatically integrates with a growing ecosystem of shared security services. This positions your application for seamless future upgrades and compatibility with new L2s, rollups, and modular chains without re-architecting security.
Institutional-Grade SLAs
We deliver enterprise service level agreements for uptime and finality. Our architecture is designed for 99.9% availability with sub-30 minute optimistic challenge windows, providing deterministic guarantees for high-frequency trading and settlement applications.

Our Development & Audit Process
A rigorous, multi-layered approach designed to deliver secure, scalable, and production-ready restaking bridge infrastructure. We focus on minimizing your technical risk and accelerating your time-to-market.
Architecture & Specification
We begin with a detailed technical design document, defining the bridge's state transition logic, fraud proof mechanisms, and integration points with L1 (Ethereum) and L2 (Optimism, Arbitrum). This ensures alignment on security assumptions and system boundaries before a single line of code is written.
Core Smart Contract Development
Implementation of the core bridge contracts in Solidity 0.8+ using OpenZeppelin libraries. This includes the deposit/withdrawal logic, state commitment hashing, and the verifier contract for fraud proof validation. All code follows gas-optimized patterns.
Internal Security Review & Testing
Before external audit, our team conducts exhaustive unit, integration, and fuzz testing. We simulate adversarial scenarios, including invalid state transitions and delayed fraud proofs, using Foundry and Hardhat to identify and remediate vulnerabilities.
Testnet Deployment & Monitoring
Deployment to a public testnet (Sepolia, Holesky) with a full monitoring stack. We test real cross-chain messaging, fraud proof submission, and economic incentives under live network conditions, gathering performance metrics before mainnet.
Mainnet Launch & Post-Launch Support
We manage the secure mainnet deployment, including multi-sig configuration and initial liquidity bootstrapping. Our team provides 24/7 monitoring and incident response support for a defined period to ensure a smooth production launch.
Frequently Asked Questions
Get clear answers on timelines, security, and process for our custom bridge architecture development.
A standard bridge deployment with core restaking functionality takes 4-6 weeks from kickoff to mainnet launch. This includes architecture design, smart contract development, integration testing, and security audit preparation. Complex multi-chain or custom fraud-proof systems can extend the timeline to 8-10 weeks. We provide a detailed project plan with weekly milestones during the initial scoping call.
