How sub-handles by ada-handle at Cardano work?

Subhandles by ADAHandle are an extension of the ADAHandle system, which operates on the Cardano blockchain. ADAHandle allows users to create unique, human-readable addresses for their wallets, replacing the need to use long, complex public keys. Subhandles take this functionality a step further by enabling the creation of secondary handles under a main ADAHandle.

How Subhandles Work:

1. Main Handle Creation: To create subhandles, you first need to register a main ADAHandle. For example, if you register @example, this becomes your primary handle.
2. Subhandle Format: Once the main handle is established, you can create subhandles in the format subname@mainhandle. For instance, you can have john@example, wallet@example, etc. These are useful for identifying different accounts or roles tied to a primary handle.
3. Ownership Structure: The owner of the main handle has complete control over the subhandles. Subhandles cannot be created or assigned by anyone other than the main handle’s owner, ensuring control and security within the ecosystem.
4. On-Chain Integration: Subhandles, like main handles, are integrated into the Cardano blockchain. This means that when a transaction is sent to a subhandle (e.g., john@example), it is effectively routed to the associated wallet address, which is tied to the main handle’s account.
5. Use Cases:
   • Personalization: Individuals or businesses can create subhandles for different purposes. For example, a business can create subhandles like sales@company, support@company, or admin@company to represent different departments.
   • Wallet Management: Users can create subhandles to manage multiple wallets under a single main handle, making it easier to organize transactions.
6. Security & Privacy: The subhandle system inherits the security features of the Cardano blockchain, ensuring that transactions to and from these addresses remain secure. However, privacy concerns may arise if subhandles are publicly associated with certain activities or identities.

Benefits of Subhandles:

• Enhanced User Experience: Subhandles simplify wallet management by allowing users to create personalized, easy-to-read addresses.
• Branding & Professionalism: Businesses or influencers can use subhandles to strengthen their brand identity on the blockchain.
• Convenience: Instead of remembering different wallet addresses, users only need to manage a main handle and its associated subhandles.

By leveraging the security and decentralization of Cardano, subhandles offer an elegant solution for wallet management and identity on the blockchain.

Can subhandles be transferred?

Virtual SubHandles cannot be sold, however if the Virtual SubHandles was Privately minted by the Handle owner, then the Handle owner can change the address to which the Virtual SubHandle resolves to.

Here’s how this works in practice:

1. Main Handle Ownership: The main handle (e.g., @example) has full control over its subhandles (e.g., john@example, wallet@example).
2. Transfer of the Main Handle: If the main handle @example is transferred to a new owner, all associated subhandles (john@example, wallet@example) are also transferred automatically along with it.
3. No Independent Transfer: You cannot independently transfer just a subhandle like john@example to another user while retaining control of the main handle. Subhandles are essentially an extension of the main handle, meaning their control and ownership follow the main handle’s ownership.

Summary:

• Subhandles are extensions of the main handle and are managed entirely by the main handle’s owner.
• SubhandlesNFT work the same way as regular Handles, it’s an NFT that can be sold or transferred at any time
• Transferring the main handle will automatically transfer all associated subhandles.

This design ensures that subhandles remain under the centralized control of the main handle’s owner, maintaining consistency and security.
