PROVEN METHODOLOGY
Our Development & Delivery Process
A structured, transparent workflow designed to deliver a production-ready, secure, and scalable cross-chain messaging SDK in weeks, not months.
01
Discovery & Architecture Design
We start with a deep technical assessment of your target chains (EVM, Cosmos, Solana, etc.) and use cases to design a gas-optimized, modular SDK architecture. This phase defines the exact message passing protocols (CCIP, IBC, Wormhole, Axelar) and security model.
1-2 weeks
Design Phase
5+
Protocols Supported
02
Core SDK & Smart Contract Development
Our engineers build the SDK core in TypeScript/Go/Rust with idiomatic APIs and develop the required on-chain smart contracts (verifiers, routers, adapters) using audited patterns from OpenZeppelin and protocol-specific security frameworks.

03
Security Audit & Penetration Testing
Every component undergoes rigorous internal review followed by a formal audit from a top-tier Web3 security firm. We simulate adversarial conditions to identify and remediate vulnerabilities in message validation, relayer logic, and economic incentives.

Cross-Chain SDK Development FAQs
Answers to the most common questions CTOs and technical founders ask when evaluating a partner for cross-chain SDK development.
We follow a structured 4-phase engagement: 1) Discovery & Scoping (1 week): Deep dive on your requirements, target chains, and architecture. 2) Development & Integration (2-4 weeks): Build, test, and integrate the SDK into your application. 3) Security Audit & Staging (1-2 weeks): Internal review and deployment to a testnet/staging environment. 4) Mainnet Launch & Support (1 week): Final deployment and handover. Most standard SDK integrations are delivered in 4-6 weeks from kickoff.
