Introduction
The ERC-3643 token standard is revolutionizing how we build compliant NFTs and tokenize real-world assets. Unlike ERC-721, which powers most NFT development, ERC-3643 embeds legal compliance directly into smart contracts. This makes it ideal for regulated industries like finance, real estate, and securities.
In this blog, we’ll explore the legal and regulatory landscape of ERC-3643 tokens, compare them with ERC-721, and guide you on how to build your first NFT using compliant smart contracts.
What Is ERC-3643 and Why Does It Matter
ERC-3643 is an Ethereum-based token standard designed for permissioned tokenization. It integrates compliance mechanisms such as KYC (Know Your Customer) and AML (Anti-Money Laundering) directly into the token’s architecture
Key Features of ERC-3643
- Identity Management: Uses ONCHAINID to verify and store user identities on-chain
- Permissioned Transfers: Only verified participants can hold or transfer tokens
- Compliance by Design: Smart contracts enforce legal rules before transactions occur
- Modular Architecture: Separates identity, compliance, and token logic for flexibility
- Interoperability: Compatible with ERC-20 platforms and DeFi tools
These features make ERC-3643 ideal for NFT marketplace integration, especially when dealing with regulated assets like tokenized real estate or securities.
ERC-3643 vs ERC-721: Legal and Technical Comparison
While ERC-721 is the go-to standard for NFTs, it lacks built-in compliance. ERC-3643 fills this gap by offering a compliance-first approach to tokenization

Why ERC-3643 Is Better for Regulated NFTs
- Legal Ownership Tracking: Essential for tokenized securities
- Jurisdictional Compliance: Supports residency and accreditation checks
- Lifecycle Management: Over 120 functions for post-issuance operations
If you’re planning to build your first NFT for a regulated market, ERC-3643 is the smarter choice.
Global Regulatory Compliance with ERC-3643
ERC-3643 is gaining traction globally due to its ability to meet international financial regulations
Supported Compliance Standards
- MiFID (Europe): For securities classification and investor protection
- SEC Guidelines (USA): For security token offerings
- AML/KYC Protocols: Embedded in smart contracts
Real-World Applications
- Real Estate: Fractional ownership with legal safeguards
- Private Equity: Tokenized shares with investor verification
- Debt Instruments: Compliant bond trading on blockchain
ERC-3643 is not just a technical upgrade—it’s a legal enabler for blockchain adoption in regulated markets.
How to Build Your First NFT with ERC-3643
Creating a compliant NFT using ERC-3643 involves several steps. Here’s a simplified NFT smart contract tutorial:
Step-by-Step Guide
- Set Up ONCHAINID
- Deploy the identity registry smart contract.
- Verify user credentials (KYC/AML).
- Use OpenZeppelin ERC-721 Implementation
- Customize with ERC-3643 compliance modules.
- Add metadata standards for asset identity.
- Deploy Smart Contract on Ethereum
- Use Solidity for ERC-721 with ERC-3643 extensions.
- Ensure compliance logic is embedded.
- Mint NFTs
- Only verified users can mint.
- Metadata includes legal ownership details.
- Integrate with NFT Marketplace
- Use platforms that support ERC-3643 tokens.
- Enable permissioned trading.
This process ensures your NFT meets ERC-3643 global compliance standards while leveraging the uniqueness of ERC-721.
Benefits of ERC-3643 for NFT Developers
- Security: Prevents unauthorized transfers.
- Scalability: Modular design supports complex assets.
- Trust: Builds investor confidence through legal compliance.
- Efficiency: Automates due diligence and ownership verification
Whether you’re a developer or investor, ERC-3643 offers a future-proof framework for NFT development.
Conclusion
ERC-3643 is redefining how we build and manage NFTs in regulated environments. By embedding compliance into smart contracts, it offers a secure, scalable, and legally sound alternative to ERC-721.
If you’re serious about NFT development, understanding ERC-3643 is essential. It’s not just a token standard—it’s a compliance-first solution for the future of digital assets.
