We architect and deploy custom smart contracts on EVM and Solana that are audit-ready from day one. Our process eliminates costly reworks and security vulnerabilities.
Blockchain Interoperability Protocol Development
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts.
Deliver a secure, scalable foundation for your token, DeFi protocol, or NFT project in as little as 2-4 weeks.
- Full Lifecycle Development: From specification and
Solidity/Rustcoding to testing, deployment, and maintenance. - Security-First Approach: Adherence to
OpenZeppelinstandards, comprehensive unit/integration tests, and formal verification. - Gas Optimization: Expert-level code to minimize transaction costs and maximize user efficiency.
- Real-World Integration: Contracts designed for seamless interaction with oracles, bridges, and existing dApp frontends.
Core Capabilities of Our Interoperability Protocols
We build production-ready, secure bridges and messaging layers that connect your application to any major blockchain network, reducing integration time from months to weeks.
Custom Bridge Development
Secure, gas-optimized token and data bridges built with IBC, Axelar, or Wormhole SDKs. We deliver full-stack solutions from smart contracts to relayers and monitoring dashboards.
Cross-Chain Messaging (CCIP)
Implement generalized message passing for complex logic like cross-chain governance, NFT minting, or DeFi composability. Supports LayerZero, CCIP, and Hyperlane.
Security & Audits
All protocols undergo formal verification and audits by firms like Quantstamp. We implement multi-sig governance, circuit breakers, and real-time threat monitoring.
Protocol Agnostic Design
Future-proof architecture that abstracts underlying bridge protocols. Easily add support for new chains (EVM, Cosmos, Solana) without rewriting core business logic.
Gas Optimization Engine
Proprietary fee estimation and batching logic reduces user transaction costs by up to 40% compared to standard bridge implementations.
Production Deployment & SLA
We handle full infrastructure deployment with 99.9% uptime SLA, automated failover, and dedicated DevOps support. Includes Grafana dashboards and alerting.
Business Outcomes: Why Invest in a Custom Interoperability Protocol
Building a custom cross-chain protocol is a strategic investment. We deliver solutions that create measurable competitive advantages and revenue opportunities.
Capture New Revenue Streams
Enable native cross-chain swaps, staking, and lending to capture fees from multiple ecosystems. Move beyond single-chain limitations and monetize liquidity across Ethereum, Solana, and Layer 2s.
Future-Proof Architecture
Build on a modular, upgradeable framework that integrates new blockchains and standards (IBC, CCIP) without costly rewrites. Avoid vendor lock-in and technical debt from generic SDKs.
Enhanced Security & Control
Own the security model with custom validators, fraud proofs, and slashing conditions. Eliminate reliance on third-party bridge risks and maintain full custody of user funds.
Superior User Experience
Deliver seamless, sub-2-minute cross-chain transactions with unified liquidity. Our protocols abstract away blockchain complexity, reducing user drop-off and increasing retention.
Sustainable Cost Structure
Optimize gas costs and fee economics with protocol-level batching and settlement logic. Reduce operational expenses versus paying per-transaction fees to external bridge providers.
Strategic Market Positioning
Launch with a unique value proposition—custom tokenomics, governance, and incentive mechanisms—to attract early adopters and liquidity, establishing your protocol as a foundational piece of the interoperability stack.
Custom Protocol vs. Generic Bridge-as-a-Service
Choosing the right interoperability foundation impacts security, scalability, and long-term control. This table compares a custom-built protocol developed by Chainscore against off-the-shelf bridge services.

Our Development Process: From Architecture to Audit
We deliver secure, production-ready interoperability protocols through a structured, milestone-driven approach. This ensures predictable timelines, transparent communication, and auditable code quality.
1. Architecture & Design
We define the protocol's core architecture, including consensus mechanisms, validator sets, and message-passing logic (IBC, Axelar, LayerZero patterns). This phase establishes the technical foundation and security model.
2. Core Protocol Development
Our engineers build the protocol's smart contracts and off-chain relayers in Rust or Go. We implement battle-tested libraries and focus on gas optimization, upgradeability patterns, and comprehensive unit testing.
3. Security Audit & Penetration Testing
Every protocol undergoes rigorous internal review followed by an external audit with firms like CertiK or Halborn. We simulate attack vectors including double-spend, griefing, and validator collusion.
4. Testnet Deployment & Monitoring
We deploy to a dedicated testnet (Goerli, Sepolia, etc.) for integration testing and load simulation. We monitor relay latency, gas costs, and failure rates to validate performance under load.
5. Mainnet Launch & Governance
We manage the secure mainnet deployment, including multi-sig setup and initial validator onboarding. We provide documentation and tooling for ongoing protocol governance and parameter tuning.
6. Ongoing Maintenance & Upgrades
We offer SLA-backed monitoring, incident response, and protocol upgrade services. This includes implementing new cross-chain standards and security patches as the ecosystem evolves.
Frequently Asked Questions on Interoperability Development
Get clear answers on timelines, costs, security, and our proven methodology for building cross-chain protocols.
For a standard cross-chain bridge or messaging layer, development and audit cycles typically take 8-12 weeks. This includes 4-6 weeks for core smart contract development, 2-3 weeks for internal security review, and 2-3 weeks for external audit integration. Complex multi-chain hub deployments can extend to 16+ weeks. We provide a detailed sprint-by-sprint roadmap during discovery.
