PREDICTABLE, TRANSPARENT, AND SECURE
Our Delivery Process for SDK Integration
A streamlined, four-phase engagement model designed to integrate MEV-resistant transaction building into your application with minimal disruption and maximum security.
01
Architecture & Discovery
We conduct a technical deep-dive to map your current transaction flow, identify MEV vulnerabilities, and design a custom integration blueprint. This ensures the SDK aligns with your specific use case, whether it's a DEX, wallet, or DeFi protocol.

Frequently Asked Questions
Get clear answers on how our service protects your users and integrates with your stack.
Our builder uses a multi-layered strategy: private mempool submission via RPC endpoints to bypass public pools, transaction simulation to detect and block front-running/sandwich attacks pre-signature, and optimal gas pricing algorithms that minimize exposure without overpaying. We've secured over $500M in user funds across 50+ integrated protocols.
