## ERC-3643 Standard

The ERC-3643 standard is a specific Ethereum improvement proposal designed to manage regulated assets on-chain. It provides a framework for creating tokens that require identity verification, such as Know Your Customer or Anti-Money Laundering checks, before a transaction can occur.

This is vital for Real World Assets that must comply with securities laws. The standard includes a built-in compliance engine that checks the eligibility of the sender and receiver against a decentralized identity registry.

By embedding these rules into the token contract itself, the standard ensures that tokens cannot be transferred to unauthorized addresses. This enables issuers to maintain control over who holds their assets while still utilizing the efficiency of blockchain technology.

It is a critical tool for institutions operating in regulated environments who want to benefit from tokenization without violating legal mandates.
