PROVEN FRAMEWORK
Our Delivery Methodology
We deliver production-ready bridge infrastructure through a structured, transparent process designed for technical founders and engineering teams. Our methodology ensures security, speed, and seamless integration.
01
Architecture & Design Sprint
We begin with a collaborative 1-week sprint to define your bridge's technical architecture, security model, and tokenomics. This phase includes threat modeling and finalizes the protocol specifications.

Frequently Asked Questions
Get clear answers on timelines, security, and integration for your cross-chain project.
Standard bridge API deployments take 3-5 weeks from kickoff to mainnet launch. This includes architecture design, core development, security review, and integration testing. Complex multi-chain or custom consensus mechanisms can extend to 8-10 weeks. We provide a detailed sprint plan within the first week of engagement.
