PROVEN PROCESS
Our Delivery Methodology
A structured, security-first approach to integrating KYC into your smart contract ecosystem, ensuring compliance without compromising on-chain performance.
01
Compliance & Architecture Review
We analyze your tokenomics, regulatory requirements, and user flows to design a compliant, gas-efficient KYC architecture. This includes selecting the optimal on-chain verification pattern (whitelist, soulbound, modular) and off-chain attestation provider.
48-72 hours
Initial Design Sprint
3+ Patterns
Architecture Options
02
Smart Contract Development
Development of custom, auditable smart contracts for KYC state management. We implement gas-optimized whitelisting, role-based access control (using OpenZeppelin), and secure integration hooks for your core protocol (DEX, NFT mint, lending).

Secure Off-Chain Integration
Build and deploy a secure, scalable backend service to bridge your chosen KYC provider (e.g., Synaps, Persona) with the blockchain. We handle signature generation, attestation storage, and real-time status updates to the smart contract layer.
