A PREDICTABLE PATH TO PRODUCTION
Our Delivery Methodology: From Spec to Mainnet
We de-risk your cross-rollup bridge deployment with a structured, phase-gated process. Each stage delivers a concrete, auditable milestone, ensuring technical alignment, security, and operational readiness before mainnet launch.
01
Phase 1: Architecture & Specification
We deliver a comprehensive technical specification and architecture design document. This includes protocol selection (e.g., Celestia, EigenDA), data availability proofs, and a detailed threat model, ensuring your bridge is built on a secure, scalable foundation from day one.

Frequently Asked Questions
Get answers to common technical and commercial questions about our specialized engineering services for secure, high-performance cross-rollup data availability solutions.
Our engagement follows a structured 4-phase approach: 1) Discovery & Architecture (1-2 weeks): We analyze your rollup stack and finalize the bridge design. 2) Core Development (3-5 weeks): We build and unit-test the smart contracts and relayers. 3) Security & Testing (2-3 weeks): This includes internal audits, testnet deployment, and a third-party audit (optional). 4) Mainnet Deployment & Handoff (1 week). A standard deployment for a single rollup pair typically takes 6-8 weeks. Complex multi-rollup or custom consensus mechanisms can extend this timeline.
