ARCHITECTURE
Core Components of Our Escrow Systems
Our cross-border escrow systems are built on a modular, secure foundation. Each component is engineered for regulatory compliance, operational resilience, and seamless integration with your existing financial workflows.
01
Multi-Jurisdictional Smart Contract Core
Custom-built Solidity contracts that encode legal terms, automate conditional fund release, and enforce compliance with KYC/AML rules across different regulatory environments. We implement OpenZeppelin security patterns and formal verification for critical logic.

Frequently Asked Questions
Get clear answers on how we build secure, compliant, and efficient smart contract escrow systems for global transactions.
A standard deployment takes 4-6 weeks from kickoff to mainnet launch. This includes 2 weeks for requirements & design, 2 weeks for core smart contract development and internal testing, and 1-2 weeks for client testing, audit integration, and final deployment. Complex multi-chain or heavily customized compliance logic can extend this to 8-10 weeks. We provide a detailed project plan with milestones at the start.
