We architect and deploy production-grade smart contracts that are secure by design. Every contract undergoes a rigorous multi-stage audit process, including automated analysis with Slither and manual review by our in-house security team, before deployment to Mainnet.
Legal Entity Onboarding System Development
Smart Contract Development
Secure, gas-optimized smart contracts built to your exact specifications.
- Custom Logic: Build
ERC-20,ERC-721,ERC-1155, and bespoke token standards. - DeFi Protocols: Develop automated market makers (AMMs), lending pools, and staking mechanisms.
- Gas Optimization: Achieve up to 40% lower transaction costs through efficient bytecode and storage patterns.
- Full Audit Trail: Receive comprehensive documentation and a verifiable security report.
From a 2-week MVP to a complex multi-chain system, we deliver contracts that are reliable, upgradeable, and ready for scale.
Core Components of Your Onboarding System
We build a fully integrated, compliant, and automated legal entity onboarding system. Each component is designed to reduce manual review, accelerate time-to-market, and ensure regulatory adherence across jurisdictions.
Automated KYC/KYB Engine
Real-time identity verification and business document validation using AI-powered checks against global sanctions lists and PEP databases. Reduces manual review time by 80%.
Smart Contract Registry & Compliance Layer
On-chain entity registry with programmable compliance rules (whitelists, transaction limits, jurisdiction flags). Built on Solidity with OpenZeppelin security patterns.
Multi-Jurisdictional Rule Engine
Dynamic policy engine that adapts onboarding flows based on entity type (LLC, DAO, Foundation) and jurisdiction (US, EU, Singapore). Ensures continuous compliance.
Audit Trail & Reporting Dashboard
Immutable audit log of all verification steps and decisions, with automated reporting for regulators (FATF Travel Rule, AML/CFT). Simplifies audits.
API Gateway & Developer Portal
RESTful APIs and SDKs for seamless integration with your existing front-end, custody solutions, and DeFi protocols. Includes comprehensive documentation.
Security & Custody Integration Layer
Secure key management architecture with MPC/TSS options and direct integrations with leading institutional custodians (Fireblocks, Copper).
Why Build a Dedicated Onboarding System
Generic KYC providers create friction and risk. A purpose-built system integrates compliance into your core product, accelerating revenue while protecting your business.
Accelerate Time-to-Revenue
Reduce onboarding time from days to minutes with automated document verification and risk scoring. Directly integrate with your treasury or trading platform to activate client accounts instantly.
Mitigate Regulatory Risk
Embedded AML/CFT checks, perpetual KYC monitoring, and immutable audit trails ensure compliance with FATF Travel Rule, MiCA, and global sanctions lists. Built-in controls adapt to jurisdictional changes.
Reduce Operational Cost
Eliminate manual review overhead and third-party vendor fees. A unified system for entity verification, beneficiary checks, and ongoing monitoring cuts compliance costs by over 60%.
Enhance User Experience
Seamless, white-labeled flows that match your brand. Support for multi-jurisdiction entity structures, document uploads, and e-signatures creates a professional first impression.
Future-Proof for Scale
Modular architecture supports new entity types, jurisdictions, and regulatory requirements. Scale to thousands of verifications daily without performance degradation.
Gain Data Sovereignty
Maintain full control over sensitive client data and compliance records. Host on your infrastructure with end-to-end encryption, avoiding third-party data breaches.

Our Delivery Methodology
We deliver secure, compliant, and scalable legal entity onboarding systems through a structured, transparent process designed to de-risk your project and accelerate time-to-market.
Discovery & Compliance Mapping
We conduct a deep-dive analysis of your target jurisdictions and required KYC/AML/KYB regulations. We map workflows to specific legal requirements, ensuring your system is built for compliance from day one.
Architecture & Smart Contract Design
Our architects design a modular system with on-chain identity anchoring, verifiable credentials, and automated compliance checks. We prioritize upgradability and gas efficiency for high-volume environments.
Secure Development & Integration
Our engineers build the core onboarding engine, integrating with leading identity providers (e.g., Synaps, Sumsub) and blockchain networks. Every module undergoes peer review and automated security testing.
Comprehensive Audit & Penetration Testing
Before deployment, the entire system undergoes rigorous third-party smart contract and web application security audits. We provide a formal attestation report for your stakeholders.
Staged Deployment & Go-Live
We deploy to testnet for final validation, followed by a phased mainnet rollout. Our team provides full operational support during launch, ensuring a smooth transition to live operations.
Ongoing Maintenance & Updates
We offer SLA-backed maintenance packages covering monitoring, regulatory update patches, and system enhancements. Stay compliant as laws evolve without rebuilding from scratch.
Frequently Asked Questions
Get clear answers on how we build secure, compliant, and automated onboarding systems for your Web3 platform.
A Legal Entity Onboarding System automates the collection, verification, and management of KYC/KYB documentation for corporate clients (e.g., VCs, DAOs, institutional funds) accessing your DeFi protocol, exchange, or tokenization platform. It's essential for compliance with global AML/CFT regulations, enabling you to serve institutional capital while managing risk. Without it, you face manual overhead, compliance gaps, and an inability to scale B2B offerings.
