RWA Tokenization Services
We build production-ready real world asset tokenization platforms — from compliant security token contracts to full investor portals — on Ethereum, Polygon, Solana, Avalanche, TON, and Blast.
Real world asset tokenization is no longer a future trend. BlackRock, JPMorgan, and Coinbase are doing it at scale. Over $32 billion in real-world assets are now tokenized on-chain — growing at 300%+ year-over-year. Analysts project the market to reach $60 billion by end of 2026 and $30 trillion by 2034 as institutional adoption accelerates. The technology works and the regulatory picture is clearer than it has ever been. What most projects are missing is a development team that understands both the blockchain infrastructure and the financial compliance layer — and can make them talk to each other cleanly. That is what we build at Blockhertz. We have worked across the full RWA stack: ERC-3643 compliant security tokens, KYC/AML-gated transfer logic, oracle-fed pricing, multi-chain deployment, and investor portal frontends. We audit every contract we ship using our own AI security tooling before it ever touches a testnet. Whether you are a real estate fund, a startup building tokenization infrastructure, a fintech exploring on-chain settlement, or an institution issuing a digital security — we can take you from whitepaper to working product.

What We Build
Everything you need, end-to-end
Security Token Smart Contracts
ERC-3643 / T-REX standard compliant tokens with built-in transfer restrictions, investor whitelisting, and compliance enforcement at the contract level. Works on Ethereum and EVM-compatible chains.
KYC/AML Integration
On-chain identity verification integrated with leading providers — Synaps, Fractal, Onfido, and Sumsub. Compliant investor onboarding without sacrificing the user experience.
Multi-Chain Deployment
We deploy across Ethereum, Polygon, Solana, Avalanche, TON, and Blast. Chain selection is driven by your asset type, investor base, and gas cost requirements — not convention.
Oracle and Pricing Integration
Real-time asset pricing via Chainlink, Pyth, and Band Protocol. Critical for debt tokens, commodity tokens, and any RWA where on-chain price feeds drive yield calculations or liquidations.
Investor Portal Development
Full-stack web application for investor onboarding, token purchase, portfolio tracking, and document management. Built on Next.js with Clerk authentication and clean mobile-first design.
Smart Contract Security Audit
Every contract we ship goes through our AI-powered security audit plus manual review. We check for reentrancy, access control, integer overflow, oracle manipulation, and 10+ other vulnerability classes before deployment.
Gas Optimization
RWA platforms handle high transaction volumes. We optimize every contract for gas efficiency — typically reducing costs by 20-40% compared to a first-pass implementation.
Compliance Documentation
Technical architecture documentation, security audit reports, and smart contract specifications written for both your legal team and regulators. Clear, precise, defensible.

Our Process
How we ship
- 01
Discovery and Architecture
We start by understanding your asset class, jurisdiction, investor base, and compliance requirements. From there we design the token architecture, select the right chain, and map the full technical stack. You get a detailed architecture document before we write a single line of code.
- 02
Smart Contract Development
We write the core token contracts, transfer restriction logic, and compliance hooks. Every function is documented and every edge case considered. We follow the Checks-Effects-Interactions pattern, use OpenZeppelin audited libraries wherever possible, and write comprehensive test suites before moving forward.
- 03
Security Audit and Testing
Before any deployment, every contract goes through our AI-powered security audit powered by Blockhertz AI Auditor, followed by a manual review. We run the full vulnerability checklist: reentrancy, access control, flash loan vectors, oracle manipulation, integer overflow, and more. You see the audit report.
- 04
Testnet Deployment and QA
We deploy to testnet and run the full investor flow end to end. KYC onboarding, token purchase, transfer restrictions, yield distributions, and secondary market transactions — all tested against real conditions before mainnet.
- 05
Mainnet Launch and Handover
We handle the mainnet deployment, verify contracts on block explorers, and configure monitoring. You receive full source code, deployment scripts, admin documentation, and a handover session. We offer ongoing support and upgrade paths as your platform scales.

FAQ
Common questions
Which blockchain is best for RWA tokenization?
Depends on the asset. Real estate and funds → Polygon or Ethereum (regulatory familiarity, liquidity). Commodities → Avalanche or Base (fast finality, low fees). Securities → Ethereum mainnet (institutional standard). We recommend chain during discovery based on your investor base and compliance requirements.
How long does a typical RWA project take?
8–14 weeks from discovery to mainnet. Smart contract development: 3–4 weeks. Security audit: 1–2 weeks. Investor portal + KYC integration: 2–3 weeks. Testnet QA + mainnet deploy: 1–2 weeks. Complex multi-jurisdiction projects run longer.
Do you handle legal and regulatory compliance?
We handle the technical compliance layer — ERC-3643 transfer restrictions, KYC/AML integration, on-chain whitelist enforcement. Legal structure (SPV, prospectus, jurisdiction) requires your own legal counsel. We can refer you to specialist RWA legal firms we have worked alongside.
What is ERC-3643 and why does it matter?
ERC-3643 (T-REX) is the institutional standard for security tokens. It enforces transfer restrictions on-chain — only verified, whitelisted investors can hold or trade the token. This is what separates a compliant security token from a generic ERC-20.
Can you tokenize any asset class?
Real estate, private equity, funds, commodities, invoices, carbon credits, and infrastructure assets. If it has a cash flow or ownership right that can be legally fractionalized, it can be tokenized. We will tell you in the discovery call if your asset class has unsolved regulatory blockers.
What does it cost?
Projects typically start at $15,000 for a single-asset MVP (smart contracts + basic investor portal). Full-featured platforms with multi-asset support, custom KYC flows, and investor dashboards range from $35,000–$80,000. Fixed-price quote provided within 48 hours of your discovery call.
Do you provide ongoing support after launch?
Yes — smart contract monitoring, security patches, chain upgrades, and investor portal updates. Retainer support starts at $1,500/month or per-incident engagements.
