# Asset Tokenization Studio FAQs: features, roles, compliance

> Answers to common questions about Asset Tokenization Studio: source code access, supported assets, roles, compliance, and Hedera integration.

<AccordionGroup>
  <Accordion title="Can I Access the Source Code for Asset Tokenization Studio">
    Check out the public [GitHub repo](https://github.com/hashgraph/asset-tokenization-studio) for the full source code. Alternatively, you can try out the[ interactive sandbox (demo)](https://tokenization-studio.hedera.com/) to explore the Asset Tokenization Studio (ATS) features.
  </Accordion>

  <Accordion title="What is Asset Tokenization?">
    Asset tokenization converts[ real-world assets (RWAs)](/support/glossary#real-world-asset-rwa) like real estate, equities, bonds, or commodities into [digital tokens](/support/glossary#digital-token) on a blockchain or other distributed ledger technology (DLT). This allows for [fractional ownership](/support/glossary#fractional-ownership), greater liquidity, and easier transferability, making these assets accessible to a wider range of investors.
  </Accordion>

  <Accordion title="What is the Difference Between a Security Token and a Digital Security?">
    A [security token](/support/glossary#security-token) represents ownership in a real-world asset and must comply with securities regulations. It often offers benefits like dividends or voting rights. [Digital security](/support/glossary#security-token) is a broader term referring to the digital form of any security, regardless of whether it's on a blockchain. It encompasses all forms of digital representations of securities, including those on traditional databases, not just those issued as tokens on a distributed ledger technology (DLT).
  </Accordion>

  <Accordion title="What is Asset Tokenization Studio?">
    [Asset Tokenization Studio (ATS)](/solutions/tokenization/ats#how-asset-tokenization-studio-ats-works) is Hedera's open-source solution designed to simplify creating, managing, and operating tokenized assets. It provides open-source tools and templates to streamline tokenization for assets like equity, debt, or real estate, with built-in compliance controls.
  </Accordion>

  <Accordion title="What Assets Can I Tokenize Using Asset Tokenization Studio?">
    You can tokenize various assets, including real estate, equities, bonds, and commodities. ATS supports different asset classes, enabling issuers to define terms and ensure regulatory compliance.
  </Accordion>

  <Accordion title="How Does the Tokenization Process Work?">
    In ATS, tokenization involves defining the asset's characteristics, setting up compliance rules, and generating digital securities on the Hedera network. Once created, these tokens can be issued and traded on the blockchain or other forms of distributed ledgers, with ATS managing the entire lifecycle.
  </Accordion>

  <Accordion title="How Does Asset Tokenization Studio Ensure Regulatory Compliance?">
    Asset Tokenization Studio integrates compliance features such as KYC/AML checks, approval lists/blocklists for eligible investors, and role-based permissions. It also supports SEC Regulations D (506-b, 506-c) and Regulation S, ensuring that tokenized securities comply with key regulatory frameworks.
  </Accordion>

  <Accordion title="Can Asset Tokenization Studio Support Additional Functions and Jurisdictions in the Future?">
    Yes, Asset Tokenization Studio is designed with flexibility in mind and can be extended to support additional functionalities and regulatory requirements for new jurisdictions in the future. Future updates aim to enhance the platform’s capabilities to meet the evolving needs of issuers and investors.
  </Accordion>

  <Accordion title="Are the Smart Contracts Used by Asset Tokenization Studio Secure?">
    Yes, the smart contracts used by Asset Tokenization Studio are audited by [A\&D Forensics](https://adforensics.com.ng/audit-services/) to ensure their security and reliability. This auditing process helps protect the platform and its users from potential vulnerabilities, ensuring a secure tokenization environment. The full audit report can be found [here](https://github.com/hashgraph/asset-tokenization-studio/blob/main/Smart%20Contracts%20Audit%20Report.pdf).
  </Accordion>

  <Accordion title="Can I Upgrade/Update a Tokenized Asset After It’s Deployed?">
    Yes, ATS allows certain [updates to tokenized assets using proxy contracts](/solutions/tokenization/ats#in-depth-architecture-of-ats). This design pattern allows you to change the logic or functionality of the token without altering the underlying asset data. When an update is needed, the proxy contract can point to a new logic contract (resolver) that defines the new rules or behaviors.
  </Accordion>

  <Accordion title="Does Asset Tokenization Studio Support ERC-3643 Compliance?">
    Yes, Asset Tokenization Studio includes partial [ERC-3643](/support/glossary#erc-3643) support by default. Full ERC-3643 integration is available as an optional configuration — during bond or equity creation, issuers can specify a Compliance ID (the smart contract enforcing regulatory rules) and an Identity Registry ID (the contract managing investor identities and compliance status) to work with existing ERC-3643 compliance infrastructure.
  </Accordion>

  <Accordion title="What Are External Management Lists and How Do They Work?">
    External Management Lists in Asset Tokenization Studio allow issuers to integrate with external smart contracts for enhanced control and compliance. These include External Pause Lists (for emergency token operation pauses), External Control Lists (for additional governance capabilities), and External KYC Lists (for third-party identity verification). Issuers can select multiple contracts from each list type during the creation process, enabling sophisticated multi-party control structures and integration with external compliance providers.
  </Accordion>

  <Accordion title="What Wallets Are Supported by Asset Tokenization Studio?">
    Asset Tokenization Studio supports wallets compatible with the Hedera network, including [MetaMask](https://metamask.io/), [HashPack](https://www.hashpack.app/), and [Blade Wallet](https://bladelabs.io/).
