We architect, develop, and deploy custom Solidity/Rust smart contracts that are secure by design. Every contract undergoes a rigorous multi-stage audit process, including automated analysis, manual review, and formal verification for critical logic.

PROVEN METHODOLOGY
Our Development & Integration Process
A structured, security-first approach to delivering production-ready confidential credit and reputation feeds. We focus on rapid integration and measurable outcomes.
01
Discovery & Architecture Design
We analyze your use case and data sources to design a custom feed architecture. This includes defining the on-chain/off-chain data flow, privacy models (ZKPs, MPC), and integration points with your existing systems.
1-2 weeks

CORE SERVICE
Custom Smart Contract Development
Secure, production-ready smart contracts tailored to your exact business logic.
We architect and deploy custom Solidity/Rust smart contracts that are audit-ready from day one. Our development process integrates formal verification and OpenZeppelin best practices to mitigate vulnerabilities before the first line of code is written.
- From Concept to Mainnet: Full lifecycle support from technical design and development to deployment and post-launch monitoring.
- Protocol-Specific Expertise: Custom logic for DeFi (AMMs, lending), NFTs (dynamic metadata, staking), DAOs, and enterprise RWA tokenization.
- Guaranteed Quality: Every contract undergoes rigorous unit testing and peer review, with comprehensive documentation for your team.
We deliver contracts you can trust, built for scale and security, not just functionality.

Frequently Asked Questions
Get clear answers on how we deliver secure, compliant, and high-performance credit scoring infrastructure for Web3 applications.
We implement a multi-layered privacy architecture. Data is encrypted at rest and in transit using AES-256 and TLS 1.3. For on-chain components, we leverage zero-knowledge proofs (ZKPs) via frameworks like Circom to compute scores without exposing raw data. Our feeds deliver verifiable attestations, not personal information. All data handling complies with GDPR and CCPA principles, and we undergo regular third-party security audits of our cryptographic implementations.
