KYC Proof-of-Compliance Ledger

overview

CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built for production by Web3-native engineers.

We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our development process is built for security and speed, delivering a production-ready MVP in 2-4 weeks.

Security-First Architecture: Built with OpenZeppelin standards, formal verification, and comprehensive unit/integration testing.
Gas Optimization: Expert-level code to minimize transaction costs for your users.
Full Audit Support: We prepare your code for third-party audits and provide remediation guidance.

We don't just write code; we deliver battle-tested infrastructure. Our contracts have secured over $50M+ in TVL across DeFi and NFT projects.

Typical Deliverables: ERC-20/ERC-721 token contracts, custom DEX/AMM logic, staking & vesting systems, multi-signature wallets, and upgradeable proxy patterns using UUPS or Transparent Proxy.

ENTERPRISE-GRADE INFRASTRUCTURE

Core Features of Our Compliance Ledger

Our KYC Proof-of-Compliance Ledger provides the foundational infrastructure for secure, scalable, and interoperable identity verification. Built for developers to integrate in days, not months.

Immutable Proof-of-Compliance

Anchor KYC/AML verification results as tamper-proof attestations on-chain. Each verification creates a cryptographic proof, enabling instant, trustless verification by any third-party protocol.

Zero-Knowledge

Privacy Layer

On-Chain

Proof Anchoring

Protocol-Agnostic SDKs

Integrate with a single API. Our SDKs support Solidity, Rust (Solana), and Cosmos SDK, with pre-built modules for DeFi, NFT marketplaces, and institutional onboarding.

PROVEN METHODOLOGY

Our Delivery Process

A structured, four-phase approach to delivering a production-ready KYC Proof-of-Compliance Ledger, designed to minimize risk and accelerate your time-to-market.

Phase 1: Discovery & Architecture

We conduct a deep-dive workshop to map your compliance workflows, data sources, and regulatory requirements. The output is a detailed technical specification and architecture diagram for your custom ledger.

2-3 Days

Workshop Duration

1 Week

Spec Delivery

Phase 2: Core Ledger Development

Our engineers build the core ledger smart contracts (e.g., on Solana, Ethereum, or Polygon) using audited patterns. This includes immutable proof storage, verifier logic, and role-based access control modules.

Solidity 0.8+

Code Standard

OpenZeppelin

Security Base

Phase 3: Integration & API Layer

We develop and deploy the off-chain API gateway and webhooks that connect your existing KYC provider (e.g., Sumsub, Onfido) to the on-chain ledger, ensuring seamless data flow and proof generation.

Phase 4: Audit & Production Deployment

The complete system undergoes a final security audit. We then manage the deployment to your chosen mainnet or testnet, provide comprehensive documentation, and conduct knowledge transfer with your team.
