ERC-3643

Smart Contract Standard

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.

Platform Evolution & Sovereignty

Smart Contract Standard Atributos

Origins Originated at Tokeny Solutions as the T-REX protocol for compliant security token issuance on Ethereum; motivated by MiFID II and other regulatory frameworks requiring KYC/AML enforcement at the token contract level for institutional RWA tokenization.
Data Formats ABI-encoded transfer calls with embedded compliance checks; ERC-20-compatible transfer interface; on-chain claims via ERC-735-style identity registry
Terms CC0
Funds Undisclosed (Tokeny Solutions is a private company)
Based On ERC-20 (extended); ERC-735 (on-chain claims model); influenced by earlier ERC-1400 security token standard
Permissions Permissioned; transfers restricted to wallets holding valid on-chain credentials issued by authorized claim issuers; issuer controls identity registry and compliance module configuration
Development Tools T-REX SDK (Tokeny); ERC-3643 Association reference implementation; Hardhat-based deployment scripts; OpenZeppelin base contracts
Protocol Maturity / Standardization Final; ERC-3643 finalized on Ethereum EIPs; T-REX v4 audited and deployed; stewardship transferred to ERC-3643 Association
Trust Framework On-chain identity registry mapping wallet addresses to verified credential claims; modular compliance contracts enforce jurisdiction-specific transfer rules; authorized claim issuers act as trust anchors
Target Application Domain Regulated real-world asset (RWA) tokenization; security tokens; tokenized funds; private equity; real estate; institutional DeFi
Deployment Model Per-token deployment with shared identity registry; compliance module and claim issuer registry deployed separately and referenced by token contracts
Standard Type Asset / Compliance Standard
Ecosystem Ethereum (and EVM-compatible chains); adopted by institutional RWA platforms including Tokeny, Polymesh integrations, and compliant DeFi protocols
