 The Digital Transfer Agent (DTA) technical standard is designed around a core principle: **separation of concerns**. This ensures a system that is secure, decentralized, and flexible. The architecture clearly distinguishes between the public-facing Request Management contract, where users interact, and the private, secure Request Settlement contract, where fund operations occur.
 
 This design allows the public, multi-tenant DTA Request Management to coexist with private, single-tenant DTA Request Settlement contracts controlled by each Transfer Agent, delivering open discovery with segregated, secure settlement.

 Every subscription and redemption request submitted to DTA Request Management moves through a predictable lifecycle controlled by a state machine. However, the exact flow depends on a critical parameter set for each fund: the Net Asset Value (NAV) Time-to-Live, or NAV TTL.
 
 The NAV TTL determines whether requests are processed manually in batches or automatically as they arrive. Understanding this distinction is key to managing your fund's operations.

 ### Components of the Chainlink DTA Technical Standard
 
 The Chainlink DTA technical standard consists of multiple components that enable onchain transfer agency services:
 
 - **DTA Smart Contracts**: Enable onchain subscription and redemption of tokenized assets across multiple blockchains, supporting both onchain and offchain settlement.
   - **DTA Request Management**: Accessed by fund distributors to submit subscription/redemption requests and by transfer agents to process pending requests.
   - **DTA Request Settlement**: Deployed by each fund administrator or transfer agent, the contract is responsible for minting, burning, and transferring the tokenized fund upon successful settlement.
-- **CCIP**: Support transfer agency services across multiple blockchains. This allows requests to be submitted on one chain and settled on another. Furthermore, fund tokens can be deployed and made available to investors across multiple blockchain ecosystems.
-- **Chainlink ACE**: Provide flexible, programmable compliance enforcement (e.g., eligibility checks, rate limits, role-based access) to enable regulators’ and institutions’ requirements to be adhered to onchain.
-- **NAVLink Feeds**: Securely link tokenized funds to the fund administrators’ NAV reporting systems to ensure accurate pricing for subscriptions and redemptions across both fiat and digital asset settlement.
-- **CRE**: Ensure compatibility with legacy systems, facilitate access to fiat settlement via [established payment rails](https://www.swift.com/news-events/press-releases/swift-ubs-asset-management-and-chainlink-successfully-complete-innovative-pilot-bridge-tokenized-assets-existing-payment-systems), and enable record reconciliation with offchain systems.
