PREDICTABLE, SECURE, SCALABLE
Our Development & Integration Process
A transparent, four-phase methodology designed for technical leaders. We deliver production-ready cross-chain staking infrastructure with clear milestones, security-first engineering, and dedicated support.
01
Discovery & Architecture Design
We begin with a deep technical workshop to define your staking model, target chains (Ethereum, Solana, Polygon, etc.), and tokenomics. Deliverables include a detailed technical specification and architecture diagram.
Client Value: Aligns all stakeholders on scope, prevents costly mid-build pivots, and establishes a clear development roadmap.

Frequently Asked Questions
Answers to common technical and commercial questions about our custom staking API and SDK development services.
A standard cross-chain staking protocol with a custom API layer and SDK typically takes 6-10 weeks from kickoff to mainnet deployment. This includes smart contract development, security audits, API/SDK integration, and testing across target chains. Complex features like multi-asset staking or novel reward mechanisms can extend this timeline. We provide a detailed project plan with milestones within the first week of engagement.
