What ERC3643 does

ERC3643 is a Luxembourg-registered non-profit association (association sans but lucratif) that stewards an open-source token standard for the issuance, management, and transfer of permissioned tokens used in real-world asset (RWA) tokenization. The protocol, originally developed by Tokeny in 2018 as T-REX and submitted as an Ethereum Improvement Proposal in 2021, achieved 'Final' status as EIP-3643 in December 2023, becoming the first tokenization standard formally approved by the Ethereum community. Its core technology combines permissioned token smart contracts with ONCHAINID, a built-in decentralized identity framework that enforces KYC/AML and offering rules at the contract level before any transfer can execute, alongside modular compliance add-ons, a T-REX Token Factory, upgradable proxies, and EVM-compatible interfaces that preserve ERC-20 interoperability.

The association operates a community-led, non-commercial model: the T-REX implementation is freely available on GitHub, and governance is distributed across Legal, Technology, Ecosystem, and Education working groups populated by member organizations. Its 92+ members as of December 2024 include financial institutions (Apex Group, ABN AMRO, Citi, Invesco, WisdomTree, Fasanara, Bitstamp), infrastructure providers (Tokeny, Polygon Labs, Chainlink Labs, LayerZero Labs, Movement Labs, Fireblocks), law firms (Norton Rose Fulbright, DLA Piper, CMS), and consultancies (Capgemini, Deloitte). Strategic integrations with Chainlink (Automated Compliance Engine, June 2025), LayerZero (cross-chain Delivery-versus-Payment, May 2025), GLEIF (LEI identity infrastructure), and Zama (Fully Homomorphic Encryption for confidential RWA) extend the standard's technical reach, while engagement with six major regulators (CSSF, BaFin, DFSA, FSRA, MAS, SEC) and an ISO standardization initiative launched in November 2025 underpin its regulatory positioning.

ERC3643 generates no direct revenue from the protocol, which is open-source and free; the legal entity has 1-10 employees and no disclosed funding. Value capture is indirect, anchored in ecosystem adoption: $32 billion+ in assets have been tokenized using the standard, 7 Onchain Factories are deployed across major blockchains, and members have launched 15+ initiatives. The protocol earned Deloitte's 'Initiative of the Year 2024' award and a 10/10 security score from Hacken. President Dennis O'Connell leads the association, with founding members including Tokeny, Apex Group, Aztec Group, Archax, Bitstamp, Capgemini, CMS, DLA Piper, DFNS, Invesco, Polygon Labs, and others.

Core offering

ERC3643 distributes the T-REX Protocol, an open-source suite of EVM-compatible smart contracts that enables the issuance, management, and transfer of permissioned tokens for real-world asset (RWA) and securities tokenization. The protocol embeds a decentralized identity framework (ONCHAINID) and modular compliance logic so that token transfers are only executed when investor and offering rules are satisfied at the smart-contract level. Governance and ecosystem development are run by the non-profit ERC3643 Association, with the standard offered free of charge.

Product overview

ERC3643 is an open-source token standard for RWA (Real World Asset) tokenization, implemented as the T-REX Protocol. The core offering consists of a suite of smart contracts enabling permissioned tokens with built-in compliance and identity verification. The protocol's architecture includes: T-REX Protocol (core tokenization standard), ONCHAINID (decentralized identity framework), Permissioned Tokens module, Compliance Management system, Tokens Factory, and Proxies for upgradability. The ecosystem is governed by the ERC3643 Association (non-profit) and T-REX DAO. The protocol is open-source, free to use, EVM-compatible, and has over $32 billion in assets tokenized. Smart contracts have been audited by Hacken with a 10/10 security score.

Recent moves6 records

Expansion highlights6 records

Others

• Chainlink: Oracle infrastructure provider and core integration partner of ERC-3643 (Automated Compliance Engine launched June 2025). Although not a direct competitor, Chainlink is an enabling ecosystem participant whose oracle services underpin ERC-3643's compliance verification workflows.

Direct peers

• Tokeny: The original creator of the T-REX Protocol (predecessor to ERC-3643) and a founding member of the ERC3643 Association. Tokeny offers a commercial enterprise tokenization platform built on the same underlying architecture, making it both a steward and a direct commercial implementer of the standard.
• Polymath: Pioneer in security token offerings with the ERC-1410/ERC-1400 standards. Competes directly in the permissioned security token infrastructure space, targeting similar institutional issuers seeking compliant tokenization.
• Securitize: Leading security token issuance and management platform that has tokenized billions in private securities. Competes with ERC-3643's permissioned token approach via its own DS Protocol and is a direct alternative for compliant RWA tokenization.
• tZERO: Security token exchange and issuance platform that pioneered regulated trading of tokenized securities. Overlaps with ERC-3643 in the compliant tokenized securities infrastructure space.

Emerging players

• Ondo Finance: Issuer of tokenized US Treasuries and yield-bearing products (OUSG, USDY). Operates in the RWA tokenization space with institutional focus and competes for the same regulated asset tokenization mandate as ERC-3643 issuers.
• Centrifuge: Tokenization platform focused on real-world assets (invoices, real estate, royalties) with its Tinlake protocol. Comparable in targeting the RWA tokenization market, though Centrifuge's primary focus is on DeFi-integrated asset financing rather than securities compliance.
• Maple Finance: Tokenized credit and lending platform serving institutional borrowers and lenders. Comparable to ERC-3643 use cases around tokenized loans and institutional-grade financial instruments, with a permissioned pool architecture.
• Provenance Blockchain: Public blockchain purpose-built for financial services, offering tokenization infrastructure for private credit, funds, and securities. Targets similar institutional issuers with a permissioned blockchain alternative to ERC-3643's EVM-based approach.

Broad incumbents

• Harbor (now part of BitGo): Harbor pioneered compliant tokenized securities issuance using ERC-1404-style standards and was acquired by BitGo. Comparable to ERC-3643 in the permissioned security token space, though now positioned as part of BitGo's broader digital asset custody and infrastructure portfolio.
