Architecture Overview

BTOS is structured as a layered operating stack.

At its foundation are tokenisation standards such as ERC-3643, ERC-4626, and ERC-7540. These support permissioned tokenisation, vault-based product structures, and asynchronous operational flows.

On top of this sits Byzanlink’s unified compliance model, which supports permissioning, whitelisting, policy control, lifecycle rule enforcement, and investor qualification logic.

At the delivery layer, BTOS provides a white-label solution and API engine that allow institutions to deploy branded product experiences and connect tokenisation workflows into their existing systems.

BTOS also connects to supporting services such as wallets, signatures, verification providers, and interoperability infrastructure.
