PROVEN METHODOLOGY
Our Development & Integration Process
A streamlined, four-phase approach designed to get your cross-chain mobile remittance product to market faster, with enterprise-grade security and reliability.
01
Discovery & Architecture
We conduct a deep technical analysis of your requirements to design a scalable SDK architecture. This includes selecting optimal source/destination chains, defining fee structures, and planning for compliance (Travel Rule, AML).
1-2 weeks
Phase Duration
100+
Protocols Analyzed
02
Core SDK Development
Our engineers build the core SDK modules in Kotlin/Swift, integrating secure key management, multi-chain wallet connectors (EVM, Solana, Cosmos), and real-time gas estimation. All code follows OWASP and blockchain security best practices.
3-4 weeks
Phase Duration
99.9%
Test Coverage
03
Bridge & Liquidity Integration
We integrate and configure production-ready bridge solutions (e.g., Axelar, Wormhole, LayerZero) and liquidity aggregators. This phase includes setting up monitoring, fallback routes, and simulating edge-case failure scenarios.

CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built to your exact specifications, from concept to mainnet deployment.
We architect and deploy production-grade smart contracts that power your protocol's core logic. Our development lifecycle ensures security-first design, gas optimization, and comprehensive testing before any code touches a blockchain.
- Custom Logic: Build on
Solidity 0.8+,Rust (Solana), orMove (Aptos/Sui)for DeFi, NFTs, DAOs, and more. - Security Rigor: Adhere to
OpenZeppelinstandards and conduct internal audits to mitigate risks before formal review. - Full Lifecycle: From technical specification and development to deployment, verification, and post-launch monitoring.
Deploy with confidence. We deliver battle-tested contracts that are secure, efficient, and ready to scale from day one.

Frequently Asked Questions
Get clear answers on integration, security, and support for our enterprise-grade SDK.
Typical integration takes 1-2 weeks for a production-ready implementation. We provide a structured onboarding process: initial setup (1-2 days), core integration of send/receive flows (3-5 days), and testing/QA (3-5 days). For teams with existing wallet infrastructure, integration can be faster.
