ERC20F (ERC-3643): compliant tokens, built for scale
Catena uses Fireblocks ERC20F, built on the ERC-3643 (T-REX) standard, for institutional-grade tokenization. The standard enables compliant, controllable representation of real-world assets and securities on-chain—with built-in transfer rules, identity checks, and a clear operational path from deployment to day-to-day operations.
Overview
What ERC-20F enables
Permissioned participation, role-based management, and operational safeguards at the contract level.
ERC20F is Fireblocks' implementation of the ERC-3643 (T-REX) standard for permissioned security tokens. Tokens are designed for regulated assets: transfer restrictions, identity binding, and compliance checks are enforced on-chain. Fireblocks provides the APIs and tooling to issue tokens, configure roles, and run operations at scale. The Fireblocks Operational Guide covers issuing new tokens, setting up roles, and day-to-day procedures.
Whether you are tokenizing funds, real estate, or other assets, ERC20F (ERC-3643) and Fireblocks give you a single, auditable stack. Catena integrates this infrastructure so you can focus on distribution and investor experience while staying in control of compliance and lifecycle.
Use the Tokenization API to deploy and link contracts, mint and burn tokens, and manage collections. Set up roles so only authorised parties can perform sensitive operations. The operational guide walks through each step for production use.
Catena builds on Fireblocks as the source of truth for tokens, balances, and transactions. Our platform adds investor onboarding, cap table visibility, and portfolio experience—all while keeping compliance and custody in your control.
