ERC-3643 Real World Assets (RWA)

The ERC-3643 token standard is designed to turn real world assets (RWAs), like company shares, loans, or real estate, into digital tokens that can be traded on the blockchain. Unlike regular tokens, it follow strict rules to make sure they meet legal requirements. With this standard, every token holder’s identity is verified to comply with regulations like Know Your Customer (KYC) and Anti-Money Laundering (AML) laws, making it ideal for assets that need extra security and regulatory approval.

Note: Hedera’s system contract functions do not natively support ERC-3643 functionalities on HTS tokens. However, standard ERC-3643 functions can still be implemented within a smart contract and deployed on the network, similar to other EVM-compatible chains.
