PROVEN PROCESS
Our Delivery Methodology
We deliver production-ready cross-chain metadata systems through a structured, transparent process designed for technical founders and CTOs. Every phase is built on audited code, documented integrations, and clear communication.
01
Architecture & Protocol Audit
We conduct a deep technical analysis of your existing smart contracts and data structures to design a secure, gas-efficient synchronization model. This includes evaluating LayerZero, Axelar, Wormhole, or CCIP for your specific use case.
48-72 hours

02
Smart Contract Development & Hardening
Our engineers build and deploy the core synchronization logic using Solidity 0.8+ with OpenZeppelin libraries. Every contract undergoes static analysis, fuzz testing, and formal verification patterns before audit.

Frequently Asked Questions
Common questions from CTOs and technical leads evaluating cross-chain data infrastructure.
Standard deployments take 2-4 weeks from kickoff to production. This includes requirements analysis, smart contract development, off-chain service deployment, and integration testing. Complex multi-protocol integrations can extend to 6-8 weeks. We provide a detailed project plan within the first 3 business days.
