ERC-3643

Estándar de Contrato Inteligente

Compliant token standard (T-REX) extending ERC-20 with on-chain identity verification and permissioned transfer logic for regulated real-world asset (RWA) tokenization. Embeds a modular compliance layer and identity registry into the token contract, ensuring only wallets holding valid credentials from authorized claim issuers can hold or transfer tokens. Designed for institutional securities, funds, and real estate tokenization within existing regulatory frameworks.
