Layer 3 AppChain Bridge Development
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts.
Deliver a battle-tested, auditable codebase that forms the secure foundation of your Web3 product.
- Full Lifecycle Development: From ideation and
Solidity/Rustcoding to deployment onEVM/Solana/Cosmoschains. - Security & Audits: Rigorous internal review, integration with
OpenZeppelinlibraries, and preparation for third-party audits. - Key Deliverables: Production-ready contracts, comprehensive documentation, and deployment scripts for 2-week MVP timelines.
Engineered for Sovereign Rollup Interoperability
Our bridge infrastructure is purpose-built for sovereign rollups, enabling seamless asset and data transfer across isolated L2/L3 environments. We deliver the foundational interoperability layer your application-specific chain requires.
Business Outcomes: From Isolated Chain to Integrated Hub
Our Layer 3 AppChain Bridge Development transforms your sovereign chain from a siloed environment into a high-value, interconnected hub. We deliver measurable outcomes that drive adoption, liquidity, and developer activity.
Multi-Chain Liquidity Access
Deploy a secure bridge to Ethereum, Arbitrum, and Base, unlocking billions in TVL for your native assets. Enable seamless cross-chain swaps and composability, directly increasing your chain's utility and attracting DeFi protocols.
Developer Onboarding Velocity
Provide developers with battle-tested SDKs and unified APIs, reducing integration time from months to weeks. Our modular bridge architecture allows teams to deploy dApps that work across your L3 and connected L2s instantly.
Enterprise-Grade Security Posture
Receive a bridge secured by formal verification and audits from firms like Spearbit. We implement multi-sig governance, fraud proofs, and continuous monitoring, providing the institutional-grade security required for high-value asset transfers.
Reduced Time-to-Market
Leverage our pre-audited, modular bridge components to launch your production-ready cross-chain capability in 6-8 weeks, not 6-8 months. Avoid the pitfalls of in-house development and focus on your core application logic.
Enhanced Token Utility & Value
Design bridge economics that incentivize holding and using your native token for fees and governance. Create sustainable revenue streams and strengthen your token's fundamental value proposition within a multi-chain ecosystem.
Future-Proof Interoperability
Build on a flexible architecture designed for the modular future. Our bridges are prepared for integration with EigenLayer AVS, AltLayer, and other emerging infra, ensuring your chain remains at the forefront of interoperability.

Our Delivery Process: From Architecture to Mainnet
We deliver production-ready Layer 3 AppChain bridges through a transparent, milestone-driven process designed for technical founders and CTOs who need predictable timelines and enterprise-grade security.
1. Architecture & Specification
We define your bridge's core architecture, including consensus mechanism, data availability layer, and cross-chain message passing protocol (e.g., IBC, Axelar, Wormhole). This phase delivers a comprehensive technical specification document for your team's review.
2. Core Bridge Development
Our engineers build the bridge's smart contracts (Solidity/Rust) and relayers using battle-tested libraries. We implement security-first patterns, including multi-sig governance, pause mechanisms, and rate limiting from day one.
3. Security Audit & Testing
Every bridge undergoes rigorous internal testing and a formal audit by a top-tier third-party firm. We provide a detailed vulnerability report and implement all critical recommendations before deployment.
4. Testnet Deployment & Integration
We deploy the bridge to a testnet environment (e.g., Sepolia, Arbitrum Goerli) and assist your team with integration. This includes SDK setup, wallet connectivity, and end-to-end transaction flow validation.
5. Mainnet Launch & Monitoring
We manage the secure mainnet deployment with phased rollouts. Post-launch, we provide 24/7 monitoring, alerting, and performance dashboards to ensure 99.9%+ uptime and rapid incident response.
6. Documentation & Handoff
We deliver comprehensive technical documentation, operational runbooks, and conduct knowledge transfer sessions with your engineering team, ensuring you have full ownership and operational control.
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts that form the backbone of your Web3 product. Our development process is built on security-first principles, utilizing OpenZeppelin libraries and comprehensive audit trails to protect your assets and users.
- Token Standards:
ERC-20,ERC-721,ERC-1155, and custom implementations. - DeFi Protocols: Automated market makers (AMMs), staking pools, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, vesting schedules, and governance modules.
- Deliverables: Full test suites, deployment scripts, and technical documentation.
We deliver audit-ready code in 2-4 weeks, reducing your time-to-market while ensuring compliance with industry security standards like
EIPspecifications.
Frequently Asked Questions on AppChain Bridge Development
Get clear, specific answers to the most common questions CTOs and founders ask when evaluating a partner for their cross-chain bridge.
For a standard, audited AppChain bridge connecting to 2-3 major chains (e.g., Ethereum, Arbitrum, Polygon), we deliver a production-ready solution in 4-6 weeks. This includes architecture, smart contract development, security audits, and a basic front-end integration. Complex multi-chain or custom consensus mechanisms can extend this to 8-12 weeks. We provide a detailed project plan with weekly milestones after the initial scoping call.
