PROVEN FRAMEWORK
Our Development & Security Methodology
We deliver production-ready cross-chain bridges with a security-first approach, ensuring your data sovereignty and system integrity from day one.
01
Architecture & Threat Modeling
We begin with a comprehensive threat model, designing a modular architecture that isolates core components (relayers, encryption, consensus) to minimize attack surfaces and ensure data integrity across chains.

Frequently Asked Questions
Get clear answers on development timelines, security, costs, and our proven process for building secure bridges between blockchains and decentralized storage.
A standard bridge MVP with core functionality (e.g., Ethereum to Filecoin/IPFS) typically deploys in 4-6 weeks. Complex, multi-chain deployments with custom encryption layers and advanced relayers can take 8-12 weeks. We provide a detailed sprint-by-sprint roadmap after the initial architecture review.
