Secure, production-ready smart contracts built by Web3 experts for your protocol or application.
We architect and deploy custom smart contracts that form the secure, immutable backbone of your application. Our development process is built on audited code patterns, gas optimization, and comprehensive testing to ensure reliability from day one.
We deliver battle-tested contracts that execute as intended, protecting your users and your reputation.
Our development stack includes:
Typical deliverables for a 4-6 week engagement:
We deliver battle-tested, modular IBC components that integrate seamlessly into your application's architecture, ensuring secure, scalable, and maintainable cross-chain communication from day one.
Deploy and manage dedicated, high-performance relayers with configurable packet filtering, fee management, and multi-chain pathing. We ensure 99.9% uptime SLAs for critical message flows.
Implement the Interchain Standard (ICS-20) for fungible token transfers with custom hooks for mint/burn logic, fee-on-transfer mechanics, and integration with your existing tokenomics.
Build bespoke Inter-Blockchain Communication (IBC) applications (ICA controllers, ICQ modules) to enable cross-chain smart contract calls, data oracles, and complex interchain logic.
Implement and automate the creation, updating, and governance of IBC light clients (Tendermint, Wasm) and connections, including misbehavior handling and state recovery procedures.
Apply rigorous security practices including IBC protocol conformance testing, state machine verification with Model Checking, and audits aligned with Cosmos ecosystem standards.
Tune IBC stack performance with packet latency optimization, mempool management, and implement comprehensive monitoring for packet success rates, queue depths, and relayer health.
Our Cosmos IBC bridge implementation delivers more than just connectivity. We build secure, scalable infrastructure that drives measurable business growth and competitive advantage.
Deploy a production-ready, audited IBC bridge in under 4 weeks, not months. We provide a complete solution including relayers, monitoring, and documentation, allowing your team to focus on core product development.
Bridge contracts are built with formal verification and audited by industry leaders like Oak Security. We implement multi-signature governance, comprehensive slashing logic, and real-time threat monitoring to protect billions in cross-chain value.
Break down ecosystem silos. Connect your Cosmos app-chain to Ethereum, Solana, and other IBC-enabled chains to tap into new liquidity pools and millions of potential users, increasing your TVL and transaction volume.
Guaranteed infrastructure uptime with proactive relayer management. We provide 99.9% SLA for bridge availability and sub-5-minute alerting for packet failures, ensuring seamless cross-chain operations for your users.
Eliminate the overhead of building and maintaining complex cross-chain infrastructure in-house. Our managed service model covers security updates, relayer operations, and protocol upgrades, cutting engineering costs by up to 70%.
Built on the latest IBC protocol standards (v3+) with modular design for easy upgrades. Seamlessly integrate new features like Interchain Accounts (ICA) and Interchain Queries (ICQ) as your product evolves.
A detailed comparison of the total cost, control, and capability of implementing a custom IBC bridge with Chainscore versus using a third-party bridge-as-a-service provider.
| Key Factor | Third-Party Bridge (e.g., Axelar, Wormhole) | Custom IBC Bridge by Chainscore |
|---|---|---|
Time to Integration | 1-2 weeks | 4-8 weeks |
Custom Logic & Features | Limited to platform | Full control and customization |
Protocol Revenue Share | Yes (0.1-0.5% per tx) | No (100% revenue retention) |
Branding & UX Control | Limited / White-label | Complete ownership |
Security & Audit Responsibility | Shared (you inherit their risk) | Full (audited, verifiable code) |
Multi-Chain Strategy Lock-in | High (vendor-specific SDKs) | None (pure IBC standard) |
Initial Development Cost | $0 - $50K (integration) | $80K - $250K (build) |
Ongoing Cost (Year 1) | $50K+ (fees + maintenance) | $20K - $60K (optional SLA) |
Long-term Technical Debt | High (dependency on external roadmap) | Low (own the core IP) |
Best For | Rapid MVP, non-core feature | Core infrastructure, scaling protocols, long-term projects |
A structured, security-first approach to building production-ready IBC bridges, designed to minimize risk and accelerate your time-to-market.
We analyze your Cosmos SDK chain and target ecosystem to design a secure, efficient IBC connection. This includes channel configuration, packet structure, and fee model design.
Implementation of IBC/TAO layer (clients, connections, channels) and custom ICS-20/ICS-721 transfer logic. Built with Rust/Go, following Interchain Standards.
Rigorous testing including unit, integration, and adversarial simulation. Optional formal verification and third-party audit coordination (e.g., Oak Security, Informal Systems).
Deployment of high-availability Hermes/Go Relayer nodes with automated monitoring, alerting, and fee management for uninterrupted cross-chain message passing.
Managed upgrade process including proposal drafting, validator coordination, and parameter tuning. We ensure a smooth transition from testnet to mainnet.

Get clear answers on timelines, costs, security, and our proven process for building enterprise-grade IBC bridges.
A standard IBC bridge connecting two Cosmos SDK chains takes 2-4 weeks from kickoff to mainnet deployment. This includes custom IBC middleware development, relayer configuration, and comprehensive testing. Complex multi-chain hubs or custom packet logic can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones during discovery.
