Sovereign KYC Chain for Regional Compliance

We architect and deploy dedicated, application-specific blockchains (AppChains) that serve as a single source of truth for KYC data, enabling compliant cross-border payments and remittance within a defined region or consortium.

overview
FULL-STACK ENGINEERING

Custom Blockchain Development

Build secure, high-performance blockchains and decentralized applications from the ground up.

We architect and develop custom blockchain solutions tailored to your exact business logic, from private enterprise chains to public mainnet deployments. Our full-cycle development delivers production-ready code in 6-12 weeks.

  • L1/L2 Development: Build bespoke chains using Substrate, Cosmos SDK, or EVM rollup frameworks.
  • Smart Contract Suites: Comprehensive Solidity/Rust development with formal verification and audit preparation.
  • Node Infrastructure: Deploy and manage validator nodes, RPC endpoints, and indexers with 99.9% uptime SLAs.
  • Cross-Chain Integration: Enable interoperability with bridges and messaging layers like LayerZero and Wormhole.

We deliver not just code, but a fully documented, maintainable system with clear upgrade paths and on-call developer support.

ENGINEERED FOR COMPLIANCE

Core Architecture & Capabilities

Our sovereign KYC chain is built on a modular, enterprise-grade architecture designed to deliver regulatory certainty, operational resilience, and seamless integration for financial institutions and Web3 platforms.

01

Modular & Sovereign Blockchain

A dedicated, application-specific blockchain (AppChain) for KYC data. This ensures complete data isolation, jurisdiction-specific rule enforcement, and eliminates cross-chain contamination risks for your compliance operations.

Zero Shared State
Data Sovereignty
Custom Consensus
Regulatory Alignment
02

Zero-Knowledge Proof Verification

Implement privacy-preserving KYC with ZK-SNARKs. Users prove compliance (e.g., residency, accreditation) without exposing raw PII, enabling secure, trustless verification for DeFi, token sales, and institutional onboarding.

PII Never Stored
Privacy by Design
< 500ms
Proof Verification
03

Automated Rule Engine & Oracles

A programmable on-chain engine that automatically enforces regional AML/CFT rules and sanctions lists. Integrated with premium oracle networks for real-time, tamper-proof regulatory data feeds.

Real-Time Updates
Sanctions Screening
100+ Jurisdictions
Rules Supported
04

Interoperability Bridges

Secure, audited cross-chain bridges (IBC, Axelar) to attest KYC status to any EVM or Cosmos-based chain. Maintain a single source of truth while enabling compliant user access across your multi-chain ecosystem.

Business Outcomes for Your Consortium

Deploy a production-ready, compliant KYC infrastructure that accelerates market entry and reduces operational overhead for all consortium members.

01

Regulatory Compliance On-Chain

We deliver a sovereign KYC chain that enforces regional AML/CFT rules as programmable logic, providing an immutable audit trail for regulators. This reduces manual compliance overhead by over 70% for member institutions.

02

Interoperable Identity Verification

Implement a reusable KYC credential system using W3C Verifiable Credentials. Once a user is verified by one member, their credential is portable across the entire consortium, eliminating redundant checks and accelerating user onboarding.

Secure, Sovereign Data Control

Deploy a dedicated, permissioned blockchain where KYC data is hashed and anchored. Members maintain full control over their node infrastructure and data residency, meeting strict data sovereignty laws (e.g., GDPR, PDPA).

PREDICTABLE, TRANSPARENT, AND SECURE

Our Delivery Methodology: From Blueprint to Mainnet

We deliver compliant, sovereign KYC infrastructure through a proven, phased approach that de-risks your project and ensures on-time, on-budget delivery.

01

Phase 1: Discovery & Compliance Blueprint

We conduct a deep-dive workshop to map your specific regulatory requirements (e.g., GDPR, MiCA, FATF Travel Rule) and define the technical architecture for your sovereign KYC chain. This phase establishes the legal and technical guardrails for the entire project.

Phase 2: Sovereign Chain Development

Our engineers build your custom, application-specific blockchain using a modular framework (e.g., Cosmos SDK, Substrate). We implement core KYC primitives: identity modules, verifiable credentials, and privacy-preserving attestations.
