ARCHITECTURE & EXECUTION
Core Protocol Capabilities We Deliver
We build the foundational identity layer for your Web3 ecosystem. Our team delivers production-ready, audited components that enable verifiable, private, and portable credit identity.
03
On-Chain Reputation & Scoring Engine
Deploy custom smart contracts that calculate and attest to creditworthiness based on on-chain transaction history, repayment events, and attested off-chain data, creating a tamper-proof reputation ledger.
05
Compliance & Consent Orchestration
Integrate regulatory modules for granular consent management, data minimalism, and audit trails. Automate compliance with frameworks like GDPR and Travel Rule, built directly into the protocol logic.

Frequently Asked Questions
Get clear answers on implementation, security, and integration for your decentralized identity solution.
A standard deployment for a production-ready identity protocol takes 4-6 weeks. This includes requirements analysis, smart contract development (Solidity/Cairo), zk-circuit design, frontend integration, and a full security audit. For proof-of-concepts or integrations with existing wallets, timelines can be as short as 2 weeks.
