ERC-3643: The Standard for Regulated Real-World Assets

The Foundation of Compliant Tokenization

ERC-3643 is the leading Ethereum token standard for permissioned digital securities. It enables programmable compliance, ensuring only verified investors can hold and transfer tokens under strict, rule-based conditions. That makes it ideal for regulated real-world asset (RWA) tokenization.

At Libertum, ERC-3643 powers our security token infrastructure — enabling seamless investor onboarding, jurisdictional restrictions, and secure, real-time transfers.

Why ERC-3643?

On-Chain KYC/KYB Enforcement

Seamlessly verify investor credentials (via providers like Sumsub) before every transfer.

Jurisdictional Compliance

Tokens follow programmable regional rules for transfer eligibility and investor categories.

Full Transfer Control

Issuers and agents can approve, freeze, or revoke transfers as needed.

Modular & Interoperable

Built on Ethereum, ERC-3643 works with wallets, dApps, and marketplaces across the ecosystem.

Built for Regulated Markets

Whether you're tokenizing real estate, equity, debt, or private funds, ERC-3643 provides the compliance backbone:
