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.

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.

01

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

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.

01

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
02

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
03

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.

KYC Proof-of-Compliance Ledger FAQ

Get specific answers on implementation, security, and ROI for our enterprise-grade compliance ledger.

A standard deployment for a KYC Proof-of-Compliance Ledger takes 4-6 weeks from kickoff to production. This includes 1-2 weeks for requirements & design, 2-3 weeks for core development and integration, and 1 week for security review and deployment. Complex multi-jurisdiction requirements or custom regulatory rule engines can extend this timeline, which we scope and quote for upfront.
