ENGINEERED FOR TRUST
Our Development & Security Methodology
We build ZK-Rollup donation platforms with enterprise-grade security and predictable delivery. Our battle-tested process ensures your platform launches on time, scales reliably, and protects donor privacy by design.
01
Privacy-First Architecture Design
We architect your platform using ZK-SNARKs (e.g., Plonk, Groth16) to anonymize donor data on-chain. Our designs separate sensitive PII from public donation records, ensuring regulatory compliance (GDPR, CCPA) without sacrificing transparency.

Proof System
PII Isolation
Data Architecture
02
Formally Verified Smart Contracts
Core donation logic and fund distribution contracts are developed in Solidity 0.8+ and verified using tools like Certora and Slither. We implement OpenZeppelin standards and custom security patterns to eliminate reentrancy and overflow risks.
