ERC-3643 Permissioned Tokens

πŸ“˜

The Open source standard for compliant asset tokenization

Tokeny is the initial creator of the ERC-3643 token protocol. After open sourcing the source code in 2023, Tokeny became one of the founding members of the ERC3643.org non-profit association, and is now contributing actively to the evolution and promotion of the ERC-3643 standard.

The ERC-3643 is documented here: https://docs.erc3643.org/


ERC-3643 is an open-source protocol for permissioned tokens, designed for the compliant representation of assets on EVM blockchain networks.

This advanced suite of smart contracts enables Issuers to tokenize any type of assets, providing a seamless and secure way to manage ownership and transactions on a decentralized ledger. ERC-3643 brings compliance and control on public or private blockchain networks.

Key Features of ERC-3643

  • Open Source: Initially created by Tokeny, the ERC-3643 protocol is now open-source, allowing for transparency and the opportunity for continuous improvement by the community.
  • Compliance-Focused: With its built-in decentralized identity framework, ERC-3643 ensures that only qualifying participants can hold and transact with these tokens, adhering to regulatory standards.
  • Versatile Tokenization: From real-world assets ("RWA") like commodities and collectibles to financial instruments such as securities and e-money, ERC-3643 supports a broad spectrum of asset tokenization.
  • Decentralized Yet Permissioned: Despite operating on permissionless blockchains, the protocol enforces permissioned token ownership, blending the best of both worlds.
  • Adoption and Recognition: As of 2023, with the establishment of the non-profit ERC3643 association and the attainment of 'Final' status for its version 4.0, the protocol has garnered official recognition and trust within the EVM developer community.
  • Designed for the Real World: Recognizing the challenges in tokenizing real-world assets and digital securities, ERC-3643 has been crafted to address these by enabling legal compliance, co-ownership rights protection, and the tokenization of a wide range of assets.
